2019-06-28x86: improve GFNI insnsJan Beulich2-23/+26
There's no need for three alternatives: "v" without TARGET_AVX512F is the same as "x". From-SVN: r272784
2019-06-28x86: fix vgf2p8affine*qb insnsJan Beulich4-4/+33
The affine transformations are not commutative (the two source operands have entirely different meaning). Also the nonimmediate_operand predicate can better be vector_operand. From-SVN: r272783
2019-06-28[ARC][COMMITTED] Fix slsr-13 regressions.Claudiu Zissulescu2-1/+6
A recent RTX cost commit has changed the costs for ARC700 leading to errors in slsr-13.c test. This commit fixes this issue by reverting the cost computation for short instructions. 2019-06-28 Claudiu Zissulescu <claziss@synopsys.com> * config/arc/arc.c (arc_rtx_costs): All short instructions are having a lower cost regardless of the speed option.

2019-06-28x86: fix CVT{,T}PD2PI insnsJan Beulich3-2/+11
With just an "m" constraint misaligned memory operands won't be forced into a register, and hence cause #GP. So far this was guaranteed only in the case that CVT{,T}PD2DQ were chosen (which looks to be the case on x86-64 only). Switch the second alternative to Bm and also replace nonimmediate_operand by vector_operand. From-SVN: r272780
2019-06-28[Arm] Remove constraint strings from define_expand constructs in the back endDennis Zhang8-618/+634
A number of Arm define_expand patterns have specified constraints for their operands. But the constraint strings are ignored at expand time and are therefore redundant/useless. We now avoid specifying constraints in new define_expands, but we should clean up the existing define_expand definitions. 2019-06-28 Dennis Zhang <dennis.zhang@arm.com> * config/arm/arm.md: Remove redundant constraints from define_expand but leave reload_inm and reload_outm patterns untouched since they need special constraints to work. * config/arm/arm-fixed.md: Remove redundant constraints from define_expand. * config/arm/iwmmxt.md: Likewise. * config/arm/neon.md: Likewise. * config/arm/sync.md: Likewise. * config/arm/thumb1.md: Likewise. * config/arm/vec-common.md: Likewise.

2019-06-27PR c++/55442 - memory-hog with highly recursive constexpr.Jason Merrill5-13/+47
This testcase in the PR is extremely recursive, and therefore uses a huge amount of memory on caching the results of individual calls. We no longer need to track all calls to catch infinite recursion, as we have other limits on maximum depth and operations count. So let's only cache a few calls at the top level: 8 seems to be a reasonable compromise. gcc/c-family/ * c.opt (fconstexpr-loop-limit): New. gcc/cp/ * constexpr.c (push_cx_call_context): Return depth.

2019-06-27[Darwin, PPC] Allow the user to override the use of hard float in kexts.Iain Sandoe2-1/+9
The default for the kernel is soft-float, however a user writing a kernel extension might want to make use of hard float.

2019-06-27[Darwin, PPC] Do not use longcall for 64b code.Iain Sandoe2-0/+14
The linker [ld64] that supports 64Bit does not need the JBSR longcall optimisation, and will not work with the most generic case (where the symbol is undefined external, but there is no symbl stub). So switch the longcall option off. ld64 will generate branch islands as needed. 2019-06-27 Iain Sandoe <iain@sandoe.co.uk> * config/rs6000/rs6000.c (darwin_rs6000_override_options): Do not use longcall for 64b code.

2019-06-26[PATCH, PPC 2/2] Fix Darwin bootstrap after split of rs6000.c.Iain Sandoe4-98/+113
To fix this we need to make the branch islands (or code) visible between both files. This keeps the generation side in rs6000.c and moves the output routine to rs6000-logue.c, placing a reference to the islands vector in rs6000-internal.h. 2019-06-26 Iain Sandoe <iain@sandoe.co.uk> * config/rs6000/rs6000-internal.h (branch_island): New typedef.

2019-06-26[PATCH, PPC 1/2] Make sure the gt- files are built for all sub-targets.Iain Sandoe2-1/+6
The new gt-rs6000-logue.h is common to all sub-targets in the port, so it needs to be added for them. It seems better to place the common target_gtfiles in the powerpc*-*-* section, rather than duplicating them in sub-targets. This would make it less likely that a sub-target would be overlooked in any future file introductions. 2019-06-26 Iain Sandoe <iain@sandoe.co.uk> * config.gcc (powerpc*-*-linux*): Move target_gtfiles from here..
