move a bunch of register constraints from being handled by
...
getRegClassForInlineAsmConstraint to being handled by
getRegForInlineAsmConstraint. This allows us to let the llvm register allocator
allocate, which gives us better code. For example, X86/2007-01-29-InlineAsm-ir.ll
used to compile to:
_run_init_process:
subl $4, %esp
movl %ebx, (%esp)
xorl %ebx, %ebx
movl $11, %eax
movl %ebx, %ecx
movl %ebx, %edx
# InlineAsm Start
push %ebx ; movl %ebx,%ebx ; int $0x80 ; pop %ebx
# InlineAsm End
Now we get:
_run_init_process:
xorl %ecx, %ecx
movl $11, %eax
movl %ecx, %edx
# InlineAsm Start
push %ebx ; movl %ecx,%ebx ; int $0x80 ; pop %ebx
# InlineAsm End
