Jonas,

I tried again on iMac with Big Sur, but even with target darwin + aarch64 I get this error:

Code: Pascal  [Select][+][-]
  1. Compiler "/usr/local/bin/fpc" does not support target aarch64-darwin

Code: Pascal  [Select][+][-]
  1. bash-3.2$ fpc -Paarch64
  2. Free Pascal Compiler version 3.2.1 [2020/11/20] for aarch64

Can I manually somehow overwrite fpc binaries to get it work?

Embarcadero promisses ARM64 support for Delphi only at second half of 2021. Whereas FPC 3.2.0 fixes already can compile for ARM64 target in macOS.
Bravo to developers of FPC!

Given their previous over-promising and under-delivering for 64 bit macOS and iOS compilers, I wouldn't be holding my breath.

Indeed. Another reason to use FPC + Lazarus rather than EMB's product.

I created first Universal App, signed, notarized DMG. It works fine on my Apple DTK and on Intel Mac.

But on real Mac Mini with M1 we've got an error for native aarch64 version:

Quote
Dec  4 11:35:57 MacMini com.apple.xpc.launchd[1]: Coalition Cache Hit: app<application.TestApp.27827332.27827354(501)> [1370]
Dec  4 11:35:57 MacMini com.apple.xpc.launchd[1] (application.TestApp.27827332.27827354[1787]): Service exited with abnormal code: 217

So I guess that we have to buy real Mac with M1 for testing. DTK can mask problems.

It seems to be FPC run-time error:

217 Unhandled exception occurred
An exception occurred, and there was no exception handler present. The sysutils unit installs a default exception handler which catches all exceptions and exits gracefully.

Igor,
 I have both a DTK and M1. I have not seen any bugs on the M1 that were not present on the DTK. However, there are several documented FPC bugs for situations where the optimization level is greater than -O1. My current approach is to develop everything with the FPC compiler (which is very quick to compile and nicely integrated into Lazarus) and then to compile the release builds with LLVM.

Optionally, for extra performance, I also add a couple of custom compiler options for LLVM that Jonas suggested. I do this by adding a couple lines to the .lpi file (I can not work out how to make a conditional for LLVM detection in the compiler options):

<CustomOptions Value="-dDisableLCLGIF
-Clflto
-Clfltonosystem"/>


So my build/notarization script cross-compiles and uses lipo to make a universal binary:

lazbuild -B --compiler=~/src/fpcllvm/lib/fpc/3.3.1/ppcx64 --ws=cocoa  --cpu=x86_64 ~/src/MRIcroGL12/MRIcroGL_Metal_llvm.lpi

lazbuild -B --compiler=~/src/fpcllvm/lib/fpc/3.3.1/ppca64 --ws=cocoa  --cpu=aarch64 ~/src/MRIcroGL12/MRIcroGL_Metal_llvm.lpi

Compared to the non-optimized FPC AArch64, this leads to substantially faster performance. Here are the times in milliseconds for a few tasks:

M1-FPC   
init   329
minmax   319
rgba   189
M1-LLVM   
init   126
minmax   81
rgba   104

I do expect FPC will close this gap as the AArch64 optimization matures - I urge everyone to help sponsor Kit's work on this

Since LLVM/Clang is what Apple uses for all their tools, it seems very optimized. All my Lazarus projects just work, including those that use OpenGL and Metal. I suspect this will resolve the bugs you are encountering, and should allow you to build perfectly fine M1 code on your DTK.

skalogryz,
Chris,

Many thanks for your quick responses and advices!

I compiled my app with FPC 3.2.1 fixes on two different Macs. With optimizations O2. I'll try O1 or O0 version. Or maybe LLVM.

Probably I incorrectly compiled some dylibs, or incorrectly signed APP (no errors after checking). I'll try to create more simple tests tomorrow.


Chris,

Even now FPC speed for aarch64 is very good for me. But your results of speed are very impressive. It would great to have these optimizations included for FPC in future.

I'll support FPC developers on Patreon. Really good idea. Thanks for reminding.

The LLVM backend is only supported on trunk. FPC 3.2.1 does not contain any of the newly added AArch64 peephole optimizations, so it shouldn't contain any bugs introduced by them either.

Jonas,

OK, I've understood. Thanks.

I've sent several test versions to a friend with Apple M1 Mac. The same problem with O1 and O0 optimizations. So our problem is not related with code optimization level.

Please file a bug report. That's probably a bug for the people working on the peephole optimizer.
