Summary: internal compiler error: in
fold_convert_const_int_from_real
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: xinlian...@gmail.com
In the following code, FE should generate FIX_TRUNC_EXPR instead of NOP_EXPR
for the float to int conversion.
extern void foo(int);
template <class Key, class Value> void Basic() {
const int kT = 1.5e6; // <--- causes ICE
int size = kT*2/3;
do {
foo(size);
size = size * 0.5 - 1;
} while (size >= 0 );
}
Note that removing the template specification, the right code is generated and
there is no ICE.
