Bug ID: 66084
Summary: ICE:internal compiler error: in fold_convert_loc, at
fold-const.c:1974
Product: gcc
Version: 4.7.4
Status: UNCONFIRMED
Severity: normal

Reporter: zhongyunde at huawei dot com
Target Milestone: ---
Created attachment 35509
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=35509&action=edit
a small case compile with -O2 can reproduce the issue

crash1.c: In function 'func_32':
crash1.c:1128:1: internal compiler error: in fold_convert_loc, at

1974: && "tree_int_cst_equal (TYPE_SIZE (type), TYPE_SIZE

__attribute__ ((vector_size (16))) zhong = ( g_73 <= g_73);
g_1124 = (((g_73 < l_1117) == zhong) << 9) ;
return 0;

--- Comment #1 from vfdff <zhongyunde at huawei dot com> ---
the following try can fix the issue, but need consider the reason why the
gcc_assert is added original ?

--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The assert is correct in that it is checking that the size of what is being
converted to a vector type is the same size as the vector.
The problem is more likely before that point.
