Summary: [6 Regression] ICE in maybe_legitimize_operand, at
optabs.c:6903 on arm-linux-gnueabihf
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: doko at gcc dot gnu.org
Target Milestone: ---
seen building a m68k-linux-gnu cross compiler, trunk 20160220:
$ cat libgcc2.i
typedef int DItype __attribute__((mode(DI)));
DItype a;
void fn1();
void fn2() {
if (a >> 1)
fn1();
}
$ build/gcc/xgcc -Bbuild/gcc/ -c -g -O2 libgcc2.i
