Summary: type mismatch in shift expression produces ice with
-O3 and -m32
Product: gcc
Version: 4.5.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: gary@intrepid.com
This bug has a failure mode similar to bug #42927, except the failure occurs
only when compiling the attached test case with both -O3 and -m32 on an x86_64
host. Checks must also be enabled.
The following output is produced:
vec-shift-m32-O3-ice.c: In function 'foo':
vec-shift-m32-O3-ice.c:22:1: error: type mismatch in vector shift expression
vector char *
vector char *
unsigned int
vect_var_.26_65 = vect_var_.23_64 v>> 64;
vec-shift-m32-O3-ice.c:22:1: error: type mismatch in vector shift expression
vector char *
vector char *
unsigned int
vect_var_.26_67 = vect_var_.26_66 v>> 32;
vec-shift-m32-O3-ice.c:22:1: internal compiler error: verify_stmts failed
Although the bug was detected in the 4.5.1 release, it can be reproduced in the
gcc-4.6-20100925 snapshot (SVN revision revision 164623) as well.
