Before:
_main:
subq $8, %rsp
leaq _X(%rip), %rax
movsd 8(%rax), %xmm1
movss _X(%rip), %xmm0
call _t
xorl %ecx, %ecx
movl %ecx, %eax
addq $8, %rsp
ret
Now:
_main:
subq $8, %rsp
movsd _X+8(%rip), %xmm1
movss _X(%rip), %xmm0
call _t
xorl %ecx, %ecx
movl %ecx, %eax
addq $8, %rsp
ret
Notice there is another idiotic codegen issue that needs to be fixed asap:
xorl %ecx, %ecx
movl %ecx, %eax
