c71886f2ca2e46ce1449c7064d6f1b447d02fcba is the first bad commit
commit c71886f2ca2e46ce1449c7064d6f1b447d02fcba

Avoid splitting store dataref groups during SLP discovery

FAIL: gcc.dg/vect/vect-gather-4.c -flto -ffat-lto-objects  scan-tree-dump-not 
vect "Loop contains only SLP stmts"
FAIL: gcc.dg/vect/vect-gather-4.c scan-tree-dump-not vect "Loop contains only

with GCC configured with

../../gcc/configure 
--prefix=/export/users/haochenj/src/gcc-bisect/master/master/r15-812/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="vect.exp=gcc.dg/vect/vect-gather-4.c --target_board='unix{-m32\ 
-march=cascadelake}'"
$ cd {build_dir}/gcc && make check 
RUNTESTFLAGS="vect.exp=gcc.dg/vect/vect-gather-4.c --target_board='unix{-m64\ 
-march=cascadelake}'"

(Please do not reply to this email, for question about this report, contact me 
at haochen dot jiang at intel.com.)
(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.)
