The following series adds ARM compilation support for the VS2017 toolchain.
* PATCH 1 targets the disabling of VS Level 4 warnings. The warnings we
chose to remove are the ones that were seen generated more than 5 times,
during the compilation of a QEMU firmware.
* PATCH 2 adds a NULL handler for the base stack check, since this is a GCC
functionality.
* PATCH 3 updates MdePkg/Library/BaseLib so that the RVCT assembly sources
are also used for MSFT.
* PATCH 4 adds the required compiler intrinsics replacements for division,
shift and memset/memcpy.
* PATCH 5 adds variable argument handlers for print output. Note that this
is done without relying on any external headers, with the VA_ARG macro
having been reverse engineered from MSFT ARM assembly output.
* PATCH 6 enables the selection of ARM in the conf templates.
With these patches, VS2017 toolchain users should be able to compile
regular UEFI ARM applications using EDK2. Note that, unlike ARM64 support,
ARM support does not require a specific update of Visual Studio 2017, as
the ARM toolchain has been available from the very first release.
Additional notes:
With an additional patch [1], it is also possible to use this proposal to
compile a complete QEMU ARM firmware. As the patch shows, the changes that
need to be applied to the EDK2 sources to achive this are actually very
minimal.
However, the generated firmware does not currently boot, possibly because
of the following warnings being generated by the MS compiler:
- ArmCpuDxe.dll : warning LNK4072: section count 118 exceeds max (96); image may not run
- UiApp.dll : warning LNK4072: section count 113 exceeds max (96); image may not run
As far as I could see, the section count max is hardcoded so a workaround
would be needed to address those.
Also, because the VS2017 ARM compiler forces a section alignment of 4096
bytes (which in turn forces use to use /FILEALIGN:4096 as a linker option
for the firmware generation), the generated firmware exceeds 2MB and we
had to double its size to 4MB.
You can find a full github repo, including this series and the additional
QEMU compilation patch at [2].
At this stage, since the goal of this series is to allow users to compile
regular ARM UEFI applications using the VS2017 toolchain, I have non plans
to spend more time on the QEMU firmware issues, especially as I suspect
that reducing the firmware size back to 2 MB may not be achievable without
Microsoft altering their compiler. I am however hopeful that ARM
specialists can take this matter over eventually...
Regards,
/Pete

* Re: [PATCH 1/6] MdePkg: Disable some Level 4 warnings for VS2017/ARM 2017-12-04 15:36 ` Gao, Liming @ 2017-12-04 17:42 ` Pete Batard 0 siblings, 0 replies; 13+ messages in thread From: Pete Batard @ 2017-12-04 17:42 UTC (permalink / raw) To: edk2-devel@lists.01.org, Gao, Liming Hi Liming, Thanks for reviewing these patches. As explained in the git comment, I chose to disable warnings that I saw being generated more than 5 times during QEMU compilation, as I suspect we may inherit things from gcc that we may not want to spend too much time changing, just to keep MSVC happy. Considering that we are introducing a new target for MS users, it may be worth being a bit more lenient with warnings for the time being, so that people don't have to spend too much time addressing issues that they wouldn't get with other compilers (gcc, Clang), if they decide to try VS2017/ARM, as it may drive them off otherwise. Especially, if we try to align ARM warnings with IA32/X64, then we're going to have to address at least 78 instances of C4244 warnings ("conversion from 'type1' to 'type2', possible loss of data") in our ARM codebase eventually, which is probably not in our best interest. For reference, here is the list of Level 4 compiler warnings I got, during QEMU compilation, along with the number of times they occurred: C4018: 7 C4101: 6 C4132: 1 C4146: 3 C4244: 78 C4366: 1 C4389: 1 C4456: 10 C4701: 50 C4703: 48 This being said, I suspect most of the warnings above may not be generated when compiling regular UEFI ARM applications or drivers, as I only started to see those when trying to compile QEMU. So, if you think that's preferable, we can proceed as you suggest, and align ARM disabled warnings with IA32 and X64. Then we can wait and see if users of VS2017/ARM start to complain that more warnings need to be disabled...

I carried this /GL- override from an earlier patch, as I was initially experiencing breakage when trying to compile some drivers without it during linking. However, I have now re-tested without this option, and I can't see any instance where /GL- appears to be needed. I will therefore remove it and submit a new patch.

You add new build for ARM. I remember the reason is that --convert-hex can't be used by trim for ARM ASM file. Right? That is correct. Maybe there's a better option to achieve just that, as duplicating the whole section just to remove an option seems a bit of an overkill... > 2. On tools_def.txt. Why introduce /D_ARM_WINAPI_PARTITION_DESKTOP_SDK_AVAILABLE option? The MSFT toolchain for ARM actively prevents compilation of native applications, when using Microsoft headers, unless this value is defined. If that is not the case, you get the error: "Compiling Desktop applications for the ARM platform is not supported." So this was needed when we were still using Microsoft headers for stdarg.h, as compilation would break otherwise. However, now that we are no longer relying on any standard headers from the VS toolchain, I just confirmed that the option is no longer needed (as the check for this definition is done in one of the Microsoft headers, not the compiler). I will therefore remove that option, as it is no longer needed. Regards, /Pete ^ permalink raw reply [flat|nested] 13+ messages in thread
