Gcc 4.3 works:
.text
.p2align 4,,15
.globl convert
.type convert, @function
convert:
movl %edi, -4(%rsp)
movss -4(%rsp), %xmm0
ret
.size convert, .-convert
.p2align 4,,15
.globl load
.type load, @function
load:
movzwl (%rdi), %eax
ret
.size load, .-load
.ident "GCC: (GNU) 4.3.0 20070731 (experimental) [trunk revision
