Bug ID: 87552
Summary: [9 regression] FAIL:
gcc.c-torture/compile/20010102-1.c -O3
-fomit-frame-pointer -funroll-loops -fpeel-loops
-ftracer -finline-functions (test for excess errors)
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: rtl-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: sch...@linux-m68k.org
Blocks: 85458
Target Milestone: ---
Target: ia64-*-*
On ia64, priorities can become negative, thus the assertion in
sel_target_adjust_priority is wrong. This only happens with -O3.
during RTL pass: mach
