Subject: [PATCH] re PR tree-optimization/46312 (gcc.dg/vec-scal-opt2.c fails
for ARM targets.)
PR tree-optimization/46312
* gcc.dg/vect/vect-scal-opt2.c: Rename to...
* gcc.dg/vect/vec-scal-opt2.c: ... this. Expect to pass only
on targets that support vector shifts with scalar shift
argument.
Remove dg-options.
* gcc.dg/vect/vect-scal-opt.c: Rename to...
* gcc.dg/vect/vec-scal-opt.c: ... this, and change likewise.
* gcc.dg/vect/vect-scal-opt1.c: Rename to...
* gcc.dg/vect/vec-scal-opt1.c: ... this, and change likewise.
* gcc.dg/vect/vect.exp: Run vec-scal-* tests with relevant
flags.
* gcc.dg/vect/vect-114.c: Expect to pass only on targets that
support misaligned data accesses.
* gcc.dg/vect/pr43432.c, gcc.dg/vect/vect-15.c: Likewise.
* gcc.dg/vect/pr43430-2.c: Remove dg-options.
* lib/target-supports.exp
(check_effective_target_vect_shift_scalar): New.
