For anyone looking to test those with Lazarus on Windows.
I have build Lazarus installers for
 - Lazarus 2.1 (trunk) + FPC 3.2rc1
 - Lazarus 2.0.7 (fixes 2.0) + FPC 3.2rc1

https://sourceforge.net/projects/lazarus-snapshots/files/

Those installers
- offer the option of a 2ndary install. So your main install will not be affected.
- are otherwise untested (not installed them myself to verify that the installed files work)
- contain a "lazarus build" of FPC RC1. That is, like all releases, the included FPC is not downloaded from FPC, but build from SVN (in this case from the 3.2RC1 tag).

Awesome.  Since this is a release candidate, I am going to try and reproduce the same FCL memory leak I detected in csvdataset here where the variable FParser isn't being freed correctly.  I'd rather the release not contain this same bug. :D

You can read about my research into this leak, and how I managed to eventually resolve it by reading my last post on this thread:

https://forum.lazarus.freepascal.org/index.php/topic,49096.0.html

And if this isn't a bug, then please let me know how I should be freeing FParser in my own code.  I will update this post once I test the RC against the leak mentioned in my thread.

Looks like this memory leak is addressed in FPC 3.2.0 RC1!  Thank you guys!  Glad I wasn't the first one to notice this issue, however, it would have been nice if someone in the forums let me know it was an issue, and is going to be resolved in the next release.  After I did a test compile, heaptrc no longer showed a memory leak.  I checked the source code in FPC trunk, and I see that a FreeAndNil(FParser); was definitely added to the Destroy destructor, resolving the memory leak.

Question: What is the relationship between this release and the fixes branch if I updated that, say, this morning Eastern Time?

The RC is based on the RC1 tag (https://svn.freepascal.org/cgi-bin/viewvc.cgi/tags/release_3_2_0_rc1/). So anything that happened in the fixes branch (https://svn.freepascal.org/cgi-bin/viewvc.cgi/branches/fixes_3_2/) since then isn't included in this release.

There is no x86_64-macos version - this rules out any Mac user with the current 64 bit only macOS 10.15.x Catalina operating system.

The i386-macosx (http://ftp://ftp.freepascal.org/pub/fpc/beta/3.2.0-rc1/i386-macosx/) release is a "fat" release. It contains both i386 and x86_64 compilers. See the Getting Started (Intel).rtf file inside the package.

IMO no, first we must branch 2.2_fixes and I hope that it'll happen in 2-8 weeks after 3.2.0 release, after that RC candidates and then release, so with most optimistic scenario
major stable version could be released 6 months after 3.2.0 is released.

Well, the Lazarus 2.2 fixes could be branched even before FPC 3.2.0 release if we decided so. I am afraid 3.2.0 release is still far away.
On the other hand, there is no need to hurry now. Instead we should improve Lazarus trunk as much as possible before branching, thus preventing the extra effort of merging commits from trunk to fixes branch.
Also new features added now in trunk would make it to Lazarus 2.2, justifying and adding substance to a new major version number.
I believe many people now must restrict their activities and stay home more than usually. The time at home can be used for bug fixing. I personally study and fix Code Explorer now.
Patches are welcome! :)

Yes. fpc searches for the real compiler in your path. Probably you have 3.0.4 installed, and that binary is in the path, and the just extracted 3.2.0 not.

In that case and as you were the one who commited my PackageRequirements patch: would you maybe take a look at this (https://lists.lazarus-ide.org/pipermail/lazarus/2019-November/237254.html) mail of mine from November where I request some feedback about me implementing selection editors, please? :) The patches won't apply cleanly anymore, but that's not the point right now. The question is in what direction I should go, especially regarding the TPropertyEditor (Note: I'd prefer to discuss this on the mailing list).

May I make a suggestion on how FPC releases could be done in the future to allow for releasing say a patched unit in the FCL, but keep the compiler/RTL coupled?

I think it would be very beneficial for both the FPC project and the developer community if the compiler/RTL were decoupled from the FCL.  This will allow fast and quick patching and/or improvements to the various FCL units, while the compiler/RTL can be released when they are known to be stable enough and production worthy.  This would essentially mimic the current FPC+Lazarus combos we see today, except with this, it will be FPC+FCL+Lazarus.  I understand how it might add some confusion, however when a developer downloads the FPC, they will have the option to also download the current FCL, or if they just want the RTL only for whatever reason, say embedded programming where most FCL units are not fully compatible, they can.  The current distribution of an all-in-one FPC install bundle should also be provided of course, as it currently is.

I'm just saying, it would be really nice to just patch the FCL once in awhile when a unit such as csvdataset is patched, but keep our current compiler/RTL.  As with Lazarus, the various FCL versions will need to denote which versions of the compiler/RTL it has been tested under, but for the most part, users won't be mixing and matching, they will just download the latest compiler/RTL/FCL install bundle as usual, and not even know that the contained FCL is even newer than the compiler/RTL.

I figure that generally FCL patches are easier to test, and usually will contain very critical patches such as for security vulnerabilities, memory leaks, and other bugs which may break applications if it is not patched soon.

For anybody interested in checking out 3.2.0 through the relative safety of a Docker container, I hereby present a Docker project which will automagically download FPC 3.2.0rc1 from the official FTP, and it also downloads binutils and builds a GO32v2 binutils, and then downloads the 3.2.0rc1 source code, and builds a full cross-compiler for GO32v2!

For clarification, here is what is included through this Docker image:


This image is great if you are compiling anything against either Linux or 16/32-bit MS-DOS targets, but don't want to mess around with your local FPC configuration/installation.  It's nicely contained in the Docker container for your enjoyment.

Something worth noting if you do plan on using this for DOS development, is that you can run the image like this:

Code: Pascal  [Select][+][-]
  1. docker run -it -v `pwd`/src:/usr/src kveroneau/fpc:3.2.0
  2.  

This will bring you inside the docker image into a bash shell where you have all the usual FPC and Linux commands at your disposal.  The default working directory is /usr/src, and this directory is binded to your host operating system.  Knowing this, you can easily create a DOS build and test pipeline on your Linux workstation using DOSBox!  Inside DOSBox just use the mount command to mount the same directory from your host.  Then use the DOSBox disk cache clearing hotkey after a compile to easily run the 16-bit or 32-bit program within DOSBox.

Here is the GitHub repo for this, if you wanted to give it a go:  https://github.com/kveroneau/fpc-docker/tree/master/Builder/fpc320

I am thinking of creating a build and uploading it to my Docker Hub page for anyone can just do a docker pull and use it without having to hit the FPC FTP servers each time someone wants to generate it.

Another fun fact about this Dockerfile, is that you can easily update the version number of FPC without a real hassle, and add additional cross-compile targets as needed.  Neat!  I feel that Docker works better a build tool, than a deployment tool.

I have taken the liberty to push my docker image up to Docker Hub.  I updated the Docker run command above, and also added a simple test along with a Makefile which will build a 16-bit .COM, 16-bit .EXE, and a 32-bit .EXE.  The Makefile can run within the docker container to generate the output binaries.  I tested the created binaries in my local DOSBox and it looks like it's good to go for anybody who wants to jump into the RC1 of FPC 3.2.0 without installing it over their existing FPC production install.

Docker Hub page for image: https://hub.docker.com/layers/kveroneau/fpc/3.2.0/images/sha256-e64ed3081691278903372ef8c5db72338bff6e4af4f5a7f964bc0045db93d4fd?context=explore

The Docker container also has nano installed and I included a Delphi syntax highlighter as well. ;)

Post by: dbannon on March 31, 2020, 02:19:18 am
Great news, thanks indeed.

It is mentioned above that the snapshots already have a couple of fixes not present in RC1, does that mean that fixes present in the snapshot will flow into RC2 and we should be testing against the snapshot ?

Or is RC1 what we should be testing and that will only change if critical things are found ?

Another matter, I find little or no wiki content about how to install eg FPC 320, beta, RC1 or snapshot.  While I have worked out my own recipe to do so, it would help get people involved in this testing phase is if was, publicly, less of a black art.  Is there a wiki page I just did not find ?  If not, I assume no one is unhappy with me making one ?

The download tar provided, at least for Linux is formed exactly like a normal release tar.  You can just download the TAR file for Linux, extract it, and then run the usual install.sh as you normally would to install FPC in Linux.  I cannot say the same for either the Windows RC1 or OSX RC1, haven't tried downloading those.

In terms of getting more people involved, the Docker image I put up should give anyone with a recent Linux machine the ability to download a working copy into a Docker container and perform testing from within it.  The Dockerfile can be easily modified to support newer snapshots and/or RCs given it is provided in the same format as RC1 has been. :D

The Dockerfile also acts as a documentation on how to install FPC 3.2.0 as well, here's the full Docker command-line I used to install FPC 3.2.0 into the Docker image, which will also work outside of Docker of course. ;)

Code: Bash  [Select][+][-]
  1. $ cd /tmp && wget -O - ftp://ftp.freepascal.org/pub/fpc/beta/3.2.0-rc1/x86_64-linux/fpc-3.2.0rc1.x86_64-linux.tar|tar -xvf -
  2. $ cd /tmp/fpc-3.2.0rc1.x86_64-linux && bash install.sh && cd /root && rm -rf /tmp/fpc-3.2.0rc1.x86_64-linux
  3.  

Hope this information helps.

The problem is that everything depending on that unit needs to be recompiled, so basically that already exists, it is called fpcdeluxe :-)

As marcov said the problem is the dependencies. Especially if changes to an interface section are involved.

And what about bug reports? Currently user report against a fixed, released version (e.g. 2.6.4, 3.0.2) or trunk. If we'd separate the FCL or even split it then the user would have to report every version of the packages they use.

That said we're working on moving at least some packages to a more repository based approach (especially those that are simply library packages) with the help of fpmake and fppkg.

From what I saw at the Berlin conference, that is still some time in the future:-)

Anyway, I just think that the current release form will mostly stay the same, just that the packages that are also in the package system will be registered to it. (though IMHO this means that package registry should not be in a global unit, but in installation directories to allow multiple versions)

Hi all, the compiler in FPC 3.2.0 rc1 seems to generate bad code when the following optimizations and configurations are used.
-CpCOREAVX2
-OpCOREAVX2
OPTIMIZATION USELOADMODIFYSTORE (enabled by default in -O3).

A quick test indicates that this issue does not exist in 3.0.4.

Yet to draft a simple demo that reproduces this error.  :(

I will study and try to understand it soon. (Not today though)

Selection editors allow to add/remove properties from the object inspector depending on the selection in the designer. In Delphi it's for example used for the TFlowPanel and TGridPanel to provide some of the non-published properties. To be more precise: if a control that's inside a TFlowPanel is selected then the Top and Left properties will be hidden (they can't be changed anyway) and a ControlIndex property will be added that allows to control the position of the control in the flow panel. With my changes that also works in Lazarus with its TFlowPanel. This mechanism can be used for other "magic" properties as well.

OK, I found it easy enough to install RC1 on a beta of (March 30) Ubuntu20.04.  The repo has RPMs but no Debs and I really did not like the look of the install script, run as root ? no thanks.

So, I converted the rpm to a deb with alien  (fakeroot alien --scripts fpc-3.2.0-0.rc1.x86_64.rpm). Lintian found enough problems with the resulting deb to publish in a small paperback but it did install OK on my clean U20.04 vm.  However, seems alien overlooked the dependencies so I found it necessary to "apt install binutils make gcc" before using apt to install the deb (remembering, of course to set an explicit path to the deb).

The result was a working compiler, so, I got confident and pulled down Lazarus trunk and, sure enough it compiled that fine too. Manually installed the fpc scr tar.gz and up came Lazarus in all its glory !  Did have a problem with running the default demo empty form in Lazarus but thats probably some Lazarus issue I have overlooked. Tomorrow's problem.

Posting this, as much as anything else, so other in the Debian fold can easily install.

You can just as well install into a custom directory. Just make sure that the bin directory is in PATH and that there are symlinks to the compiler binaries in the lib subdirectory so that you can call the compiler driver fpc and that in turn can call the real compiler ppc386, ppcx64, etc.

OK, I found it easy enough to install RC1 on a beta of (March 30) Ubuntu20.04.  The repo has RPMs but no Debs and I really did not like the look of the install script, run as root ? no thanks.

You can just as well install into a custom directory. Just make sure that the bin directory is in PATH and that there are symlinks to the compiler binaries in the lib subdirectory so that you can call the compiler driver fpc and that in turn can call the real compiler ppc386, ppcx64, etc.

When I use the install.sh script to install whichever version, I run the script as my user, and place the installation into my home directory on Debian.  Has been working perfectly, no issues besides needing to recompile the TextMode IDE if I plan to use it, so that it links to the correct libraries on my system.

Fpcupdeluxe, latest release, now has the possibility to install release candidates.

Navigate towards the tags-tab.
The lists will be filled from online sources.
Select the tag you want to use.
Press add tag.
It will be added towards the bottom of the normal target selection list in the basic tab.

Downloads are available at the main FTP server,

ftp://ftp.freepascal.org/pub/fpc/beta/3.2.0-rc1/

Is there any faster mirror? I'm only getting a max download speed of 400kb/s. %)

Also the ftp protocol should be replaced with http/https because webbrowsers are going to remove FTP support completely. Chrome (https://developers.google.com/web/updates/2019/12/chrome-80-deps-rems) this month and Firefox (https://groups.google.com/forum/#!msg/mozilla.dev.platform/FqCZUT9ay_o/jt4DLRDjAwAJ) in beginning of 2021.

From the release testing procedure:
Code: [Select]
5. open the installed hello.pp in IDE
6. make a minor change in the demo in IDE & save it
7. compile the demo file in IDE
8. run the demo within the IDE (debugger)
9. view documentation in IDE, traverse 2-3 pages (at least one with screenshots)
...
11. run testsuite

Which IDE is being talked about?

Where's the "test suite"?

It's also a little disheartening to see that only two users have signed up for testing (https://wiki.freepascal.org/Testers_3.2.0#Release_Testing_Procedure), and both macOS users.

This is about a FPC release. So it can only talk about the textmode IDE.

Where's the "test suite"?

It's normally located in $fpsrc/tests, though I'm not really sure if a) we distribute it with the releases and b) if it would work without the sources. Also considering that we don't have 0 failures on any platform I don't think it would be that useful of the testers to run them anyway - cause they can't determine whether the test failure is a known one or not.

trev, the ide ? if you have set your path to the fp bin dir, the command is 'fp'.   Its sure brings back memories !

The tests are in the source tar.gz, its extracted to fpc-3.2.0rc1/tests

Now, my question ?

Having completed the tests, what do we do with the report ?   In my case, its quite detailed -
Code: [Select]
Total = 7754 (25:7729)
Total number of compilations = 4781 (13:4768)
Successfully compiled = 3606
Successfully failed = 1162
Compilation failures = 9
Compilation that did not fail while they should = 4
Total number of runs = 2973 (12:2961)
Successful runs = 2961
Failed runs = 12
Number units compiled = 152
Number program that should not be run = 477
Number of skipped tests = 504
Number of skipped graph tests = 10
Number of skipped interactive tests = 31
Number of skipped known bug tests = 7
Number of skipped tests for other versions = 4
Number of skipped tests for other cpus = 267
Number of skipped tests for other targets = 185
make[1]: Leaving directory '/home/dbannon/fpcsrc/fpc-3.2.0rc1/tests'
We have successful fails, things that should fail but did not, but particularly 12 "Failed Runs". Do we need to provide details of those failed runs ? 

This log seems to have had a number of failures too -

Hmmm - this wiki page (https://wiki.lazarus.freepascal.org/How_to_get_the_fpc_ide_running_under_Mac_OS_X) suggests it did once upon a time run on macOS using Quartz/X11. As it's not in the current macOS RC1, I guess it's no longer supported despite the man page.

And that's why I doubt that it's useful for testers to run the tests. :-X At most you could compare your test results against one of the official ones for the same target with the same settings and report differences... (for a list of failed tests you can look at $fpcsrc/tests/output/<cpu>-<os>/faillist)

Correct. Jonas does not want to support the IDE on macOS (for many years already), so the best would be a bug report to remove the man page for that target as well.

In i386-win32, there's both the native compiler and the cross compiler for 64bit, which is what I'd expect.

In x86_64-win64, however, there seems to be only the native compiler. How do I get the cross-compiler for win32?

We do not provide a cross compiler from Win64 to any other x86 target, because Win64 does not support the Extended type which is supported by all other x86 targets (there are plans for software emulation, but this is currently not fully implemented).

What you can do however is to simply copy the ppc386 from the distribution as well as the units and copy that into your x86_64 installation (you should copy the binary into %fpcdir%\bin\x86_64-win64 next to the fpc.exe) then you can use fpc -Pi386 just as well.

Hello all,

First of all thanks to all contributors for the new release candidate. I know I am late to the party but I finally got around testing the Win64 version against my own library. I used O4 plus -CpCOREI - OpCOREI on a Nehalem processor

* the library uses a lot of required typecasting and tricky code linearizations
* all library tests (several thousands) passed
* I saw speed improvements (compared to FPC 3.0.4) of 3%-10% depending on function type and size of operands

From my perspective its looking good.

Kind regards,
MathMan

I hope the developer/packager would package a jvm cross compiler for Linux.

They provided one for Windows, didn't they?

On Linux, we only have a cross compiler for msdos.

It is not too difficult to build the jvm cross compiler on linux your self. Just follow the steps in the wiki and make sure you have the correct toolchain (jasmin etc)
Parent platform does not matter too much as long as it supports Java. https://wiki.freepascal.org/FPC_JVM

(Tested on Windows 7, 32-bit)

Val procedure (https://www.freepascal.org/docs-html/current/rtl/system/val.html) (and StrToFloat (https://www.freepascal.org/docs-html/current/rtl/sysutils/strtofloat.html) as well) fails with SIGFPE with Math.MaxDouble.

As Val should never raise exception (but only return non-zero value in third parameter), this is even more annoying.

First, take a look at this simple programme. It works with FPC 3.0.4, but not with FPC 3.2:

Code: Pascal  [Select][+][-]
  1. program project1;
  2.  
  3. {$mode objfpc}{$H+}
  4.  
  5. uses SysUtils, Math;
  6.  
  7. var
  8.   D1, D2: Double;
  9.   S: AnsiString;
  10.   E: Integer;
  11. begin
  12.   D1 := Math.MaxDouble;
  13.   WriteLn('D1 = ', D1);
  14.  
  15.   S := FloatToStr(D1);
  16.   // If you replace the previous line with any of the following two, then everything works!
  17.   // But the difference is only in + sign in front of exponent.
  18.   //WriteStr(S, D1);
  19.   //Str(D1, S);
  20.  
  21.   WriteLn('S = ', S);
  22.   Val(S, D2, E);  // SIGFPE here!
  23.   //D2 := StrToFloat(S); // same with this, as it uses Val internally.
  24.  
  25.   WriteLn('D2 = ', D2);
  26.   ReadLn;
  27. end.
  28.  

Now, let's see:
First, the declaration of Math.MaxDouble changed in FPC 3.2
In 3.0.4 it was:
MaxDouble    =  1.7e+308;
And in 3.2 it is:
MaxDouble    =  1.7976931348623157e+308;

Now, if we use old Pascal Str function, or WriteStr, then we get '1.7976931348623157e+308' as result.
FloatToStr gives us '1.7976931348623157e308' (the difference is only in + sign in the exponent).

Then without this + sign, Val gives SIGFPE!

However, it seems that this bug in Val only appears when string value has 16 digits (and MaxDouble has it in FPC 3.2).

I know I am very very late to the game, and I know we should have pushed for inclusion of our bug fix earlier, and should have made it clearer that this is not a "minor" issue as it was classifed.

So, I'll be clear NOW:

Each and every multi-threaded FPC/Lazarus application will sooner or later Deadlock on TEvent, causing a complete unrecoverable failure of the program. Finding out what the issues might take the average user weeks.

It's a terrible nasty bug that sometimes may take ages to show up again, but if it does, you are doomed.

I really really REALLY believe this is an absolute must-fix bug for the stable branch of FPC.

Please consider to stop the release and pull in this fix. The fix is heavily tested by us under load for months, is stable and does not have any side effects - it simply stops FPC server deamons to sooner or later deadlock.

First of this is the announcement forum, you simply don't have the necessary permissions to start a new topic here. For your topic (a port for System 360) you should look at the Free Pascal -> FPC development forum or use the fpc-devel (https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-devel) mailing list.
Also you don't simply join the core team. You can get access to your own SVN branch and work there or you fork the unofficial mirror (https://github.com/graemeg/freepascal/) on GitHub. You then work on your port and then present your work (either on the mailing list or the Bugtracker (https://bugs.freepascal.org)) and we core devs will integrate it if it's okay or pass it back to you for improvements. Once your new port is integrated then or if you further "prove your worth" you'll be elevated to a team member.
Additionally someone else has started to work on a port for the ZSeries (https://wiki.freepascal.org/ZSeries). I don't know if they still work on it or if there were any results, but maybe you can use that as a starting point.

Do you think that using the -k parameter could do the trick?

Something like this?:

Code: Pascal  [Select][+][-]
  1. fpc -kld.bfd myprog

I installed FPC 3.04 from source on FreeBSD 12-STABLE r361007 amd64 with no issues.

I have ld soft-linked to ld.bfd.  I also compile the world + kernel without issue.

Thanks for the tip!
[EDIT]
Yes it solves the problems.

But tricky.

On my FreeBSD 12 OS, there are 2 binaries /usr/local/bin/ld.bfd and /usr/local/bin/ld.

And /usr/local/bin/ld is a binary, not a symlink to ld.bfd.

If I may (and this without any hostility, please trust me) it would be great to have a build-in solution in fpc himself.
For example in fpc-compiler code something like this:

Code: Pascal  [Select][+][-]
  1. {$IFDEF freebsd}
  2. // use ld.bfd
  3. {$ENDIF}

With FreeBSD there are only few distros (FreeBSD, Ghost, ...) that use the same architecture, with ld.bfd in same directory, so no risk of incompatibilities.

Issue I report on mailing list

http://free-pascal-general.1045716.n5.nabble.com/Segmentation-fault-with-cthreads-on-FreeBSD-td5735669.html#a5735673

I was using older FreeBSD 12.

Few days ago, I setup new fresh FreeBSD 12.1 installation. Latest binutils (2.33) does not ship with ld.bfd anymore. So symlink ld to ld.bfd workaround does not work anymore.

I install FPC 3.0.4 from source. Initially, it compiles fine but generated executable cause segmentation fault when executed. Compiling same exact program second time however works flawlessly and executable works. I have no idea why.

Hello.

Not sure to understand.
Are you saying that binutils (2.33) does not give ld.bfd but ld yes.

And that using ld from binutils (2.33) your program test compiles + runs ok?

Hum, I have downloaded last FreeBSD pkg binutils-2.33.1_2,1.txz but it gives here both ld.bfd and ld.

But, warning, it is not impossible that between 2 sub versions, there can be strange change in FreeBSD package.

(And imho the way that FreeBSD manage his packages is **more** than strange.)

FreeBSD 12.1 does not have ld.bfd anymore

https://lists.freebsd.org/pipermail/freebsd-current/2018-November/072212.html

A few minutes a go, I just setup another fresh FreeBSD 12.1 X86_64, install FPC 3.0.4 using fpc-3.0.4.x86_64-freebsd11.tar

Using fresh installed FreeBSD and FPC 3.0.4, I compile
Code: Pascal  [Select][+][-]
  1. program test;
  2. {$IFDEF UNIX}
  3. uses cthreads;
  4. {$ENDIF}
  5. begin
  6.      writeln('test');
  7. end.
Compilation works but executable causes segmentation fault. Compiling second time, same segmentation fault.

Then I install binutils

Code: Bash  [Select][+][-]
  1. #pkg install binutils
which install binutils 2.33. Compiling again and this time executable works.

I observe that no ld.bfd binary, and ld still symlink to ld.lld. So I guess it fixed because I install binutils.

FreeBSD 12.1-STABLE amd64 r361007.

I just cd /usr/ports/devel/binutils/ and make deinstall && make install and:

$ /usr/local/bin/ld -v
GNU ld (GNU Binutils) 2.33.1

$ /usr/local/bin/ld.bfd -v
GNU ld (GNU Binutils) 2.33.1

So, yes, Binutils v2.33.1 does still install ld.bfd as well as an ld binary which is in fact ld.bfd too. My symlink from earlier in the year has been wiped out and replaced with the ld.bfd binary.

Hum, in my FreeBSD 12.0 there are also /usr/local/bin/ld and /usr/local/bin/ld.bfd, with exactly same size.

But using /usr/local/bin/ld for link with fpc crash the program, using /usr/local/bin/ld.bfd is ok.
So it is obvious that the 2 binaries are not the same.

So maybe that in the new binutils, /usr/local/bin/ld and /usr/local/bin/ld.bfd are in fact the same now.

If somebody knows the logical of the FreeBSD package, I am interested to have some explanation.

FreeBSD 12.1 does not have ld.bfd anymore

https://lists.freebsd.org/pipermail/freebsd-current/2018-November/072212.html

This mostly seems to be about ld.bfd in base, for us this doesn't matters that much if the binutils in ports works.
