Bug ID: 100518
Summary: ICE in copy_to_mode_reg, at explow.c:651
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: marxin at gcc dot gnu.org
Target Milestone: ---
Host: x86_64-linux-gnu
Target: aarch64-linux-gnu
It's likely a recent regression:
$ cat stringop.i
int unsigned_range_min, unsigned_range_max, a11___trans_tmp_1;
void a11() {
a11___trans_tmp_1 = unsigned_range_max < unsigned_range_min;
__builtin_memset((char *)1, 0, a11___trans_tmp_1);
}
$ aarch64-linux-gnu-gcc stringop.i -mabi=ilp32 -mstrict-align -O2 -c
during RTL pass: expand
stringop.i: In function ‘a11’:
stringop.i:5:3: internal compiler error: in copy_to_mode_reg, at explow.c:651
5 | __builtin_memset((char *)1, 0, a11___trans_tmp_1);

[PR100518] store by mult pieces: keep addr in Pmode
The conversion of a MEM address to ptr_mode in
try_store_by_multiple_pieces was misguided: copy_addr_to_reg expects
Pmode for addresses.
