Bug ID: 86662
Summary: msp430-elf segfault with -flto and -mlarge
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: jozef.l at mittosystems dot com
Target Milestone: ---
Segfault after endless recursion in gimple_get_alias_set, caused by canonical
type for __int20 being set to the unsigned variant, rather than signed variant
as expected.
testcase.i
int main(void)
{
__int20 n = 5;
}
./build/gcc/xgcc -B./build/gcc -nostdlib testcase.i -mlarge -flto
