For example, I execute the following command sequences: H:\CI\bld\compilers\musl\src\math\i386>type sqrt.s #.globl _sqrt .global sqrt #.type sqrt, at function #_sqrt: sqrt: fldl 4(%esp) fsqrt fstsw %ax sub $12,%esp fld %st(0) fstpt (%esp) mov (%esp),%ecx and $0x7ff,%ecx cmp $0x400,%ecx jnz 1f and $0x200,%eax sub $0x100,%eax sub %eax,(%esp) fstp %st(0) fldt (%esp) 1: add $12,%esp fstpl 4(%esp) fldl 4(%esp) ret H:\CI\bld\compil...

I found that access llvm-mc from clang driver is impossible, and I want to use llvm-mc to compile assembly files, how to do that?
