Bug ID: 96028
Summary: SEGV in vect_create_constant_vectors
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: ro at gcc dot gnu.org
CC: rguenth at gcc dot gnu.org
Target Milestone: ---
Host: sparc-sun-solaris2.11
Target: sparc-sun-solaris2.11
Build: sparc-sun-solaris2.11
The new gcc.dg/torture/pr95761.c test causes an ICE on 64-bit Solaris/SPARC:
+FAIL: gcc.dg/torture/pr95761.c -O3 -fomit-frame-pointer -funroll-loops
-fpeel-loops -ftracer -finline-functions (internal compiler error)
+FAIL: gcc.dg/torture/pr95761.c -O3 -fomit-frame-pointer -funroll-loops
-fpeel-loops -ftracer -finline-functions (test for excess errors)
+FAIL: gcc.dg/torture/pr95761.c -O3 -g (internal compiler error)
+FAIL: gcc.dg/torture/pr95761.c -O3 -g (test for excess errors)
Excess errors:
