I have a few projects that I may be interested in hiring or paying a bounty for. Unfortunately there are as far as I know no bounty platform for fpc but anyone that is interested in getting any of this done is welcome to contact me. I am just going to write them down and see what responses I get.
FPC pCode compiler backend. Compile Pascal in an easy to use pCode that can be analyzed by tools for things like optimization or memory leak detection. This is not something like llvm but something more high level like the pCode generated by old pascal compiler as well as some similarity to Java Bytecode.
pVM. A virtual machine for running pCode that is as portable as possible, potentially with a lot of debugging tooling options.
pCode to C compiler. Compile pCode into C compatible with GCC and IAR. Targets like ARM and MSP430 is a priority for me. Such as the Raspberry Pi Pico which is a good reference platform.
ARM M-series libraries and tooling. This has to be broken down into smaller projects.
Raylib UI for raspberry PI (and other platforms). Create an UI that look and feel like the classic windows ui and preferably has a similar API. Long term this should be an LCL replacement but that is not as important as having a full set of nice looking widgets that uses a very minimal amount of resources.
