Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Summary|ICE in |ICE with LTO and |emit_library_call_value_1, |-fshort-double |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;
