Bug ID: 101468
Summary: [r12 regression] new Wstringop-overflow tests failures
since r12-2338
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: clyon at gcc dot gnu.org
Target Milestone: ---
Since r12-2338, I've noticed that some of the new tests fail on arm/aarch64.
On aarch64:
FAIL:
gcc.dg/Wstringop-overflow-71.c (test for warnings, line 103)
gcc.dg/Wstringop-overflow-71.c (test for warnings, line 104)
gcc.dg/Wstringop-overflow-71.c (test for warnings, line 32)
gcc.dg/Wstringop-overflow-71.c (test for warnings, line 43)
gcc.dg/Wstringop-overflow-71.c (test for warnings, line 66)
gcc.dg/Wstringop-overflow-71.c (test for warnings, line 77)
gcc.dg/Wstringop-overflow-71.c (test for warnings, line 90)
gcc.dg/Wstringop-overflow-71.c (test for warnings, line 91)
gcc.dg/Wstringop-overflow-71.c (test for excess errors)
UNRESOLVED:
gcc.dg/strlenopt-95.c scan-tree-dump-not strlen1 "abort \\("
gcc.dg/strlenopt-95.c scan-tree-dump-not strlen1 "strlen \\("
on aarch64_be, we have two XPASS in addition to the FAIL above:
gcc.dg/Wstringop-overflow-47.c pr97027 (test for warnings, line 77)
gcc.dg/Wstringop-overflow-47.c pr97027 note (test for warnings, line 68)
on arm-eabi, with default configuration flags, we have:
XPASS:
gcc.dg/Wstringop-overflow-68.c pr?????? (test for warnings, line 61)
gcc.dg/Wstringop-overflow-68.c pr?????? (test for warnings, line 62)
gcc.dg/Wstringop-overflow-68.c pr?????? (test for warnings, line 63)
gcc.dg/Wstringop-overflow-68.c pr?????? (test for warnings, line 64)
gcc.dg/Wstringop-overflow-68.c pr?????? (test for warnings, line 65)
FAIL:
gcc.dg/Wstringop-overflow-70.c (test for warnings, line 19)
gcc.dg/Wstringop-overflow-70.c (test for excess errors)
gcc.dg/Wstringop-overflow-71.c (test for warnings, line 103)
gcc.dg/Wstringop-overflow-71.c (test for warnings, line 104)

UNRESOLVED:
gcc.dg/strlenopt-95.c scan-tree-dump-not strlen1 "abort \\("
gcc.dg/strlenopt-95.c scan-tree-dump-not strlen1 "strlen \\("
When forcing RUNTESTFLAGS to
-mcpu=cortex-a7/-mfloat-abi=hard/-march=armv7ve+simd, in addition to the above
we have:
XPASS:
gcc.dg/Wstringop-overflow-47.c pr97027 (test for warnings, line 77)
gcc.dg/Wstringop-overflow-47.c pr97027 note (test for warnings, line 68)
and gcc.dg/Wstringop-overflow-70.c no longer fails
