FAIL: gcc.dg/tree-ssa/pr92834.c scan-tree-dump-times optimized "MAX_EXPR <" 8
FAIL: gcc.dg/tree-ssa/pr92834.c scan-tree-dump-times optimized "MIN_EXPR <" 8

with GCC configured with

../../gcc/configure --prefix=/export/users3/haochenj/src/gcc-bisect/master/master/r16-4726/usr --enable-clocale=gnu --with-system-zlib --with-demangler-in-ld --with-fpmath=sse --enable-languages=c,c++,fortran --enable-cet --without-isl --enable-libmpx x86_64-linux --disable-bootstrap

To reproduce:

$ cd {build_dir}/gcc && make check RUNTESTFLAGS="tree-ssa.exp=gcc.dg/tree-ssa/pr92834.c --target_board='unix{-m32\ -march=cascadelake}'"
$ cd {build_dir}/gcc && make check RUNTESTFLAGS="tree-ssa.exp=gcc.dg/tree-ssa/pr92834.c --target_board='unix{-m64\ -march=cascadelake}'"

(Please directly reply to this email for question about this report.)
(If you met problems with cascadelake related, disabling AVX512F in command line might save that.)
(However, please make sure that there is no potential problems with AVX512.)
