Environment:
- VS 2022 with latest MSVC toolset(v14314.43.34808), and Windows SDK version(10.0.22621.0).
- Arm64 Windows PC.
I want to build ARM64EC version of V8 engine, but failed with following error:
> Studio/2022/Professional/VC/Tools/MSVC/14.43.34808/lib/ARM64" "-libpath:../../../../../../../../Program Files (x86)/Windows Kits/10/lib/10.0.22621.0/ucrt/arm64" "-libpath:../../../../../../../../Program Files (x86)/Windows Kits/10/lib/10.0.22621.0/um/arm64" /MACHINE:ARM64EC "/IMPLIB:./third_party_abseil-cpp_absl.dll.lib" /DLL "/PDB:./third_party_abseil-cpp_absl.dll.pdb" "@./third_party_abseil-cpp_absl.dll.rsp"
lld-link: error: ignoring unknown argument: -arm64xsameaddress:__dyn_tls_dtor
lld-link: error: -arm64xsameaddress:__dyn_tls_dtor is not allowed in .drectve (msvcrt.lib(tlsdtor.obj))
In tlsdtor.cpp, there is a linker option:
`#ifdef _M_ARM64EC
#pragma comment (linker, "-arm64xsameaddress:__dyn_tls_dtor")
#endif`
It seems that Microsoft VS added arm64xsameaddress option to support some arm64EC compatibility, but lld-link did not notice the fact.
After that, I tested a minimal program hello.cpp with following content:
`#include <iostream>
#pragma comment (linker, "-arm64xsameaddress:__dyn_tls_dtor")
int main() {
std::cout << "Hello, World!" << std::endl;
return 0;
}`
If I use MSVC cl.exe and link.exe, it was successful:
> cl /c /WX- /Od /D _DEBUG /D _CONSOLE /D _UNICODE /D UNICODE /EHsc /MDd /GS /fp:precise /arm64EC hello.cpp
link /MACHINE:ARM64EC hello.obj
Run hello.exe and the output was 'Hello, World!'.
But If I use clang-cl and lld-link, it complained following error:
> clang-cl.exe /c /WX- /Od /D _DEBUG /D _CONSOLE /D _UNICODE /D UNICODE /EHsc /MDd /GS /fp:precise /arm64EC hello.cpp
lld-link /MACHINE:ARM64EC hello.obj
lld-link: warning: ignoring unknown argument: -arm64xsameaddress:__dyn_tls_dtor
lld-link: error: -arm64xsameaddress:__dyn_tls_dtor is not allowed in .drectve (hello.obj).
Another question:
Here, I used clang-cl from LLVM github latest release version:
> clang-cl.exe -v
clang version 20.1.0
Target: aarch64-pc-windows-msvc
Thread model: posix
But If I use clang-cl from VS 2022 installed version, compile any .cpp file would complain as follow:
> clang-cl -v
clang version 19.1.1
Target: aarch64-pc-windows-msvc
Thread model: posix
> clang-cl.exe /c /WX- /Od /D _DEBUG /D _CONSOLE /D _UNICODE /D UNICODE /EHsc /MDd /GS /fp:precise /arm64EC hello.cpp

fatal error: too many errors emitted, stopping now [-ferror-limit=]
20 errors generated.
This might be the same problem as the linker option error.
