We are currently making an effort to make ARM (and AARCH64 eventually)
builds using Microsoft's Visual Studio Compiler (aka MSVC/MSFT).
These 3 patches correspond to an effort to make the assembler work with
MSFT, which entails :
- Feeding MSFT the RVCT .asm files, since they share syntax
requirements.
- Fixing some instructions syntax in those .asm files, in order to make
them palatable for MSFT.
- Fixing some minor formatting issue in INF files, while we're at it.
This set enables the assembler, meanwhile the C also require changes,
which will come in a set later. This set makes the RVCT toolchain family
and profiles obsolete, unblocking :
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=1750
As mentioned in the above bug, dropping RVCT would entail orphanating
the .asm files that powered the RVCT build. Since Visual Studio uses the
same file syntax, those can be reused to power the VS build.
These patches have been tested on VS2019 (v15.9.11) and VS2017 (v16.0.1)

Frankly, looking at it, I can't quite manage to untangle how we end up generating A32 for .asm in the first place. Is it just the toolchain default? If we look for example at the post-build version of Build/ArmVirtQemu-ARM/RELEASE_GCC5/ARM/ArmPkg/Library/ArmHvcLib/ArmHvcLib/OUTPUT/Arm/ArmHvc.iii , there is no .arm directive. That gets assembled into Build/ArmVirtQemu-ARM/RELEASE_GCC5/ARM/ArmPkg/Library/ArmHvcLib/ArmHvcLib/OUTPUT/Arm/ArmHvc.obj by the step --- "arm-linux-gnueabihf-gcc" -march=armv7-a -c -x assembler -imacros /work/git/tianocore/Build/ArmVirtQemu-ARM/RELEASE_GCC5/ARM/ArmPkg/Library/ArmHvcLib/ArmHvcLib/DEBUG/AutoGen.h -mlittle-endian -o /work/git/tianocore/Build/ArmVirtQemu-ARM/RELEASE_GCC5/ARM/ArmPkg/Library/ArmHvcLib/ArmHvcLib/OUTPUT/Arm/ArmHvc.obj -I/work/git/edk2/ArmPkg/Library/ArmHvcLib/Arm -I/work/git/edk2/ArmPkg/Library/ArmHvcLib -I/work/git/tianocore/Build/ArmVirtQemu-ARM/RELEASE_GCC5/ARM/ArmPkg/Library/ArmHvcLib/ArmHvcLib/DEBUG -I/work/git/edk2/MdePkg -I/work/git/edk2/MdePkg/Include -I/work/git/edk2/MdePkg/Include/Arm -I/work/git/edk2/ArmPkg -I/work/git/edk2/ArmPkg/Include /work/git/tianocore/Build/ArmVirtQemu-ARM/RELEASE_GCC5/ARM/ArmPkg/Library/ArmHvcLib/ArmHvcLib/OUTPUT/Arm/ArmHvc.iii --- (Adding hilarity to the situation is the bit where we, when preprocessing the file, explicitly pass -mthumb on the command line - which is obviously ignored at that point.) Fwiw, yes, it appears at least the Debian toolchain defaults to assembling A32 if no .thumb directive is explicitly in place. > What I don't want is a situation where the toolchain's default decides > how code is assembled, since that means you have to test all your code > changes twice. And to me it looks like we avoid that problem today only by accident - we are already relying on toolchain defaults for GCC. Anyway, rewinding this about 27 steps ... Are you OK with Baptiste going ahead and adding the ARM statement *only* to the files requiring it to build[1] - and the one(s) requiring it to operate properly (could you point it/them out please)? [1] Then the next question is whether he should also add it to the files where that avoids the need for (some) refactoring of code, or whether he should simply mirror the changes to .asm into .S? The "we must tie down so that each .asm/.S file is only ever built to a single instruction set" work is a substantial enough task, that I hope we can undertake at a later date rather that rolling it into this one. / Leif ^ permalink raw reply [flat|nested] 33+ messages in thread

Since we use GCC for both compiling and linker, but invoke the assembler directly (and don't pass the C flags in this case), we end up with binutils using ARM by default.

I agree with this as a general rule, but for this (hopefully never to be repeated) operation, it makes sense to me to keep each change in this set as one patch. For the simple reason that the alternative leaves several unusable commits in sequence in the repository. There is simply no way to bisect through this change on a per-package basis. This is after all a horrible horrible hack that lets us keep using the .asm files provided for one toolchain family (RVCT) in a different toolchain family (MSFT), without having to delete and re-add, losing history in the process.

(The question was posed to Liming, but I'm going to follow up here with my own thoughts, after getting CC'd by Liming. Thanks for that BTW.) Let's assume the changes are split up with a fine granularity. Under that assumption, consider two cases: (1) ARM builds on Visual Studio are broken until the last patch is applied, but all other toolchains continue working fine throughout the series. versus (2) ARM builds are broken on Visual Studio *and* on at least one other -- preexistent -- toolchain, until the last patch in the series is applied. Which case reflects reality? If it's case (1), then I prefer the fine-grained patch series structure. Nothing regresses with existent toolchains (so bisection works with them), we just have to advertise the last patch in the series as the one that enables Visual Studio. If it's case (2), then I agree with the larger (multi-package) patch, as a rare exception. (We can also put it like this: if it's *possible* to write this series such that it enables (1), then we should strive for that.)

I agree with your logic. It's just that I'm not even aware of anyone who has *tried* building with RVCT for several years. So we leave the "probably not working" toolchain potentially working for a few more commits, as a tradeoff against enabling the new one in one go. (Now, fair, there are other issues with the VS ARM port that as per the cover letter will also need to be addressed before the port is fully functional.) / Leif ^ permalink raw reply [flat|nested] 33+ messages in thread

Ard Biescheuvel asks : "Why ?" The practical reason would be because it breaks an "grep -nr "| ${toolchain}" " (although with some regex magic I guess it can be circumvented, but one would need to know in advance that there are places where there aren't spaces) The second reason would be because it breaks the standard format used in all other inf files. But if you find this is useless, I'll drop this one !
