|at calls.c:3757 |
--- Comment #10 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
-fshort-double is what is causing the issue. Why are you using that option in
the first place? It changes the ABI.
With 4.7.0 (and checking enabled), I get the following ICE on all targets with
-flto -fshort-double -Os:
t7.c: In function ‘main’:
t7.c:3:5: error: non-trivial conversion at assignment
float
double
# .MEM_2 = VDEF <.MEM_1(D)>
f = 1.0e+0;

--- Comment #4 from Sylvain Laperche <sylvain.laperche at gmail dot com> ---
I downloaded the source of GCC 4.8.2 from here[1].
I compiled it with and without --disable-nls, in both case it works fine. I
cannot reproduce the issue I encounter with the the binary from the official
repository of Archlinux.
That seems to be an issue related to my environment or to the packaging done by
the distribution.
