JIT: Fix LA64 and RISCV64 build errors on Windows #100099

jakobbotsch · 2024-03-21T19:47:08Z

This allows the LA64 and RISCV64 crossjits to build with MSVC (when enabled in the CMakeLists.txt files for JIT and gcinfo).

The motivation is to make it easier to validate that we don't break RISC-V/LA64 builds during broad refactorings (case in point -- #100091).

This allows the LA64 and RISCV64 crossjits to build with MSVC (when enabled in the CMakeLists.txt files for JIT and gcinfo).

There are a number of "possible loss of data" warnings related to the helpers like NBitMask that required adding a bunch of casts in many places in this file. I went with just disabling these warnings since I did not want to uglify all of that code. Perhaps there is a prettier way to fix these warnings.

Disabling this warning is SDL violation:

runtime/eng/native/configurecompiler.cmake

Line 847 in ac07ea6

add_compile_options($<$<COMPILE_LANGUAGE:C,CXX>:/we4244>) # 'conversion' conversion from 'type1' to 'type2', possible loss of data

It is only ok as long as this code is not getting compiled in official builds.

@dotnet/samsung Can you please provide a patch that fixes the warnings in your preferred way without resorting to disabling the warning? Thanks!

@jakobbotsch Thank you.
@Bajtazar Could you fix the warnings in emitriscv64.cpp? The most of warnings are casts related to helpers which you have refactored. I think you can fix in prettier way. :)

Hi, I prepared a patch that fixes warnings in the emitriscv64.cpp file

@Bajtazar I think the patch can be merged separately. Could you make another PR for your patch?

Thank you!

@Bajtazar I think the patch can be merged separately. Could you make another PR for your patch?

You can open a separate PR or I can include it in this change. Up to you.

@clamp03 @jakobbotsch I've opened a separate PR with fixes (#100270)

Do we intend to enable them in main at some point (such as part of this PR)?
