Bug ID: 102944
Summary: Many gcc.dg/Wstringop-overflow-*.c failures
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: testsuite
Assignee: unassigned at gcc dot gnu.org
Reporter: ro at gcc dot gnu.org
CC: crazylht at gmail dot com
Target Milestone: ---
Target: sparc-sun-solaris2.11, m68k-unknown-linux-gnu,
moxie-unknown-elf, aarch64-suse-linux-gnu,
mipsel-mti-elf, arm-none-linux-gnueabihf
Between 20211019 (ff0eec94e87dfb7dc387f120ca5ade2707aecf50) and 20211020
(d98626bf451dea6a28a42d953f7d0bd7659ad4d5),
quite a number of testsuite failures occured. I'm seeing them on Solaris/SPARC
(32 and 64-bit), but gcc-testresults show reports for many others:
+FAIL: gcc.dg/Warray-parameter-3.c pr102706 (test for warnings, line 80)
+FAIL: gcc.dg/Wstringop-overflow-14.c pr102706 (test for warnings, line 39)
+XPASS: gcc.dg/Wstringop-overflow-14.c pr102706 (test for warnings, line 40)

+XPASS: gcc.dg/Wstringop-overflow-76.c pr102706 (test for warnings, line 50)
AFAICS they are due to

Adjust testcase for O2 vect.
Adjust code in check_vect_slp_store_usage to make it an exact
pattern match of the corresponding testcases.
These new target/xfail selectors are added as a temporary solution,
and should be removed after real issue is fixed for Wstringop-overflow.

This patch seems to have caused
+FAIL: gcc.dg/Warray-bounds-48.c pr102706 (test for warnings, line 133)
+FAIL: gcc.dg/Warray-bounds-48.c pr102706 (test for warnings, line 33)
I'm seeing it on 64-bit sparc, and there are also reports for
s390x-ibm-linux-gnu and m68k-unknown-linux-gnu. It may be a
coincidance, but those are all big-endian targets.

There seems to be a miss optimization issue, open pr103076 to track that.
If the miss optimization isssue is fixed in vectorizer, those testcase would
pass, if not, i'll adjust my patch.

I don't see any of the FAILs or XFAILs listed in comment #0 with cross
compilers for any of the Targets. Can this report be resolved?
I do see some unexpected failures with an m68k-unknown-linux-gnu cross in other
tests. I opened pr103751 for those.

I thinks so, now we only have
+FAIL: gcc.dg/Warray-bounds-48.c pr102706 (test for warnings, line 133)
+FAIL: gcc.dg/Warray-bounds-48.c pr102706 (test for warnings, line 33)
on sparc, s390x-ibm-linux-gnu and m68k-unknown-linux-gnu, and i've opened PR
for that.

The failures last occured on sparc*-sun-solaris2.11 on 20211101 and on
i386-pc-solaris2.11 on 20210716, so for my targets the issue is fixed
indeed.
