Bug ID: 101012
Summary: ice in vect_slp_analyze_node_operations
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: dcb314 at hotmail dot com
Target Milestone: ---
Created attachment 50976
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=50976&action=edit
C source code
For the attached C code, compiled with today's gcc trunk and
compiler flag -O3, does this:
bug446
during GIMPLE pass: vect
tif_getimage.c: In function ‘putRGBseparate8bittile’:
tif_getimage.c:1618:13: internal compiler error: in
vect_slp_analyze_node_operations, at tree-vect-slp.c:4442
0x5fd6fd vect_slp_analyze_node_operations
../../trunk.git/gcc/tree-vect-slp.c:4442

../../trunk.git/gcc/tree-vect-slp.c:4385
The bug first seems to occur sometime after git hash
91349e57bbfd0101, dated a couple of days ago, and git
hash f8b067056ba5dd53, dated today.
I will have my usual go at reducing the code. If someone
else wants to do the git bisect, then that's fine by me.

--- Comment #1 from David Binderman <dcb314 at hotmail dot com> ---
Reduced C code seems to be:
putRGBAAseparate8bittile_w(int *cp, unsigned char *g) {
char *a, *r;
unsigned *b;
int _x;
for (; _x; _x -= 8) {
*cp++ = *r++ | (unsigned)*g++ << 8 | *b++ << 16 | (unsigned)*a++ << 24;
*cp++ = *r++ | (unsigned)*g++ << 8 | *b++ << 16 | (unsigned)*a++ << 24;
}
}
This bug seems strongly related to gcc bugzilla # 86179, which was
# 446 on my list of 724.
