gcc.log from commit 829c0c06fe7b
Our CI detected that commit 99b5921bfc8f "Handle TYPE_OVERFLOW_UNDEFINED
vectorized BB reductions" introduced these testsuite failures on aarch64-linux:
=== gcc tests ===
Running gcc:gcc.dg/tree-ssa/tree-ssa.exp ...

I confirmed that they are still present in trunk as of commit 829c0c06fe7b
"Fortran: improve diagnostic message for COMMON with automatic object
[PR32986]" from today.
The tests above fail with these messages found in gcc.log:
- gcc.dg/tree-ssa/slsr-11.c: pattern found 3 times
- gcc.dg/vect/bb-slp-29.c: pattern found 2 times
- gcc.dg/vect/pr53773.c: pattern found 0 times
Tested on Ubuntu 22.04 with:
$ ~/src/gcc/configure \
--disable-bootstrap \
--disable-multilib \
&& make -j 60 \
&& make -C gcc check-gcc RUNTESTFLAGS="gcc.dg/tree-ssa/tree-ssa.exp
gcc.dg/vect/vect.exp"
I'll attach gcc.log from trunk.
