2017-01-20 Jakub Jelinek <jakub@redhat.com>
* gcc.c (offload_targets_default): New variable.
(process_command): Set it if -foffload is defaulted.
(driver::maybe_putenv_OFFLOAD_TARGETS): Add OFFLOAD_TARGET_DEFAULT=1
into environment if -foffload has been defaulted.
* lto-wrapper.c (OFFLOAD_TARGET_DEFAULT_ENV): Define.
(compile_images_for_offload_targets): If OFFLOAD_TARGET_DEFAULT
is in the environment, don't fail if corresponding mkoffload
can't be found. Free and clear offload_names if no valid offload
is found.
libgomp/
* target.c (gomp_load_plugin_for_device): If a plugin can't be
dlopened, assume it has no devices silently.

commit e7c4d49ab27338e6bc8b0272c4036da58482bde0

S/390: Fix flogr RTX.
The flogr instruction uses a 64 bit register pair target operand. In
the RTX we model this as a write to a TImode register. Unfortunately
the RTX's being assigned to the two parts of the target operand were
swapped. This is no problem if in the end the flogr instruction will
be emitted since the instruction still does what the clzdi expander
expects. However, a problem arises when the RTX is used to optimize
CLZ for a constant input operand. Even then it matters only if the
expression couldn't be folded on tree level already.
In the testcase this happened thanks to loop unrolling on RTL level.
The iteration variable is used as an argument to the clz
builtin. Due to the loop unrolling it becomes a constant and after
folding the broken RTX leads to a wrong assumption.

* config/rs6000/rs6000-string.c (select_block_compare_mode): Move test
for word_mode_ok here instead of passing as argument.
(expand_block_compare): Change select_block_compare_mode() call.
(expand_strncmp_gpr_sequence): New function.
(expand_strn_compare): Make use of expand_strncmp_gpr_sequence.
