[LLVMdev] Question about '-fno-exceptions' option and 'ExceptionsType' on MCAsmInfo with ARM.
...or a way to avoid generating stack unwinding codes when
compiling with the "armv7-none-linux-gnu" triple using clang. I tried
the '-fno-exceptions' option in order to do that, but unwinding function
symbols like '__aeabi_unwind_cpp_pr0' were still present. I think
'ExceptionType' of MCAsmInfo is set to ExceptionType::ARM with the above
target triple and it is not affected by the '-fno-exceptions' option. Am
I missing something about this, or do we need to provide an interface to
disable generation of exception codes?
Thanks,
