The disabled warnings for ARM are now aligned with IA32 and X64. * 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, by reusing the RVCT code, as well as 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: We tested compiling and running the full UEFI Shell with this series, as well as a small set of applications and drivers, and found no issues. 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 achieve 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. 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 no 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...
