[cfe-users] Issue when clang launches "ld.lld.exe" in Windows OS through "-fuse-ld=ld.lld"

[Ni, Ray via cfe-users]

Dear clang experts,
I want to build out ELF image using clang in Windows OS. But I met an issue when using "-fuse-ld=ld.lld" to ask clang launch ld.lld.exe as a linker.
Somehow clang always passes additional parameter to ld.lld: "-libpath:E:\\bin\\LLVM\\lib\\clang\\12.0.0\\lib\\windows" -nologo
I found this behavior when I pass "-v" to clang. With "-v", clang will output the complete command line about how ld.lld is invoked.

Command as below:


"E:\bin\LLVM\bin\clang" -o e:\work\edk2\Build\UefiPayloadPkgX64\DEBUG_CLANGDWARF\IA32\UefiPayloadPkg\UefiPayloadEntry\UniversalPayloadEntry\DEBUG\UniversalPayloadEntry.elf -nostdlib -Wl,-n,-q,--gc-sections -z common-page-size=0x40 -Wl,--entry,_ModuleEntryPoint -u _ModuleEntryPoint -Wl,-Map,e:\work\edk2\Build\UefiPayloadPkgX64\DEBUG_CLANGDWARF\IA32\UefiPayloadPkg\UefiPayloadEntry\UniversalPayloadEntry\DEBUG/UniversalPayloadEntry.map,--whole-archive -fuse-ld=ld.lld -flto -Wl,-melf_i386 -Wl,--format=elf @e:\work\edk2\Build\UefiPayloadPkgX64\DEBUG_CLANGDWARF\IA32\UefiPayloadPkg\UefiPayloadEntry\UniversalPayloadEntry\OUTPUT\static_library_files.lst -v
