Bug ID: 83508
Summary: [8 regression][arm] c-c++-common/Wrestrict.c fails
since r255836
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org
Reporter: clyon at gcc dot gnu.org
Target Milestone: ---
Hi,
I've noticed that c-c++-common/Wrestrict.c fails on arm targets. This appeared
between r255831 and r255842, and I suspect it's beacuse of r255836.
I noticed that when forcing "old" cpus to be targetted, for instance by putting
-march=armv5t in RUNTESTFLAGS.
Another possibility is to keep gcc's default --with-cpu configure option.
My gcc.log has:
Excess errors:
/gcc/testsuite/c-c++-common/Wrestrict.c:761:3: warning: '__builtin_memcpy'
writing 4 bytes into a region of size 0 overflows the destination
[-Wstringop-overflow=]
