--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
So perhaps it was my r11-2944-g0106300f6c3f7bae5eb1c46dbd45aa07c94e1b15
that broke it?
Seems mingw -m32 uses empty LOCAL_LABEL_PREFIX:
#define LOCAL_LABEL_PREFIX (TARGET_64BIT ? "." : "")
and so emits:
        flds    LC1
...
        .section .rdata,"dr"
        .align 4
LC1:
        .long   -8388608
        .align 4
LC2:
        .long   2139095040
etc.
But on the testcase it emits:
        .set    _LC5,_LC6
If you change manually that .set _LC5,_LC6 to .set LC5,LC6, does it work th=
en?=
