Message-ID: <20070808003330.22952.qmail@sourceware.org> (raw)
In-Reply-To: <bug-30961-7667@http.gcc.gnu.org/bugzilla/>
------- Comment #29 from hjl at lucon dot org 2007-08-08 00:33 -------
With revision 85770, I got
[hjl@gnu-27 rrs]$ cat convert.s
.file "convert.c"
.text
.align 4
.p2align 4,,15
.globl convert4
.type convert4, @function
convert4:
movq %rdi, -8(%rsp)
movq %rdi, -16(%rsp)
movlpd -8(%rsp), %xmm0
ret
.size convert4, .-convert4
.ident "GCC: (GNU) 3.5.0 20040810 (experimental)"
.section .note.GNU-stack,"",@progbits
Remove the extra mvoq won't solve this regression.
