[LLVMdev] [compiler-rt] cmake fails to configure for AArh64
...to aarch64-linux-gnu-g++, which
the compiler does not need and doesn't understand as the option is
redundant for AArch64.
I tracked down where -m64 was originating from and found the following
in compiler-rt/CMakeLists.txt:
if (NOT MSVC)
set(TARGET_64_BIT_CFLAGS "-m64")
set(TARGET_32_BIT_CFLAGS "-m32")
else()
set(TARGET_64_BIT_CFLAGS "")
set(TARGET_32_BIT_CFLAGS "")
endif()
After the line with -m64 is commented out, cmake can complete the
configuration and I am able to cross compile the whole LLVM.
Could you please advise if this is a known problem...
