Bug ID: 127031
Summary: avr: stack smash in synth_mult for SImode multiply
Product: gcc
Version: 17.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: ptomsich at gcc dot gnu.org
Target Milestone: ---
While characerising PR127028, we triggered the following:
during RTL pass: expand
plainmul.c:2:26: internal compiler error: Segmentation fault
0x9e9214 synth_mult
gcc/expmed.cc:2953
with the reproducer:
typedef __UINT32_TYPE__ u32;
u32 f (u32 x) { return x * 0xaaab; }
using 'avr-gcc -O2' (default avr2 core, no hardware MUL).
