2019-06-03Fix PR64242 - Longjmp expansion incorrectWilco Dijkstra4-28/+35
Improve the fix for PR64242. Various optimizations can change a memory reference into a frame access. Given there are multiple virtual frame pointers which may be replaced by multiple hard frame pointers, there are no checks for writes to the various frame pointers. So updates to a frame pointer tends to generate incorrect code. Improve the previous fix to also add clobbers of several frame pointers and add a scheduling barrier. This should work in most cases until GCC supports a generic "don't optimize across this instruction" feature. Bootstrap OK. Testcase passes on AArch64 and x86-64. Inspected x86, Arm, Thumb-1 and Thumb-2 assembler which looks correct. gcc/ PR middle-end/64242 * builtins.c (expand_builtin_longjmp): Add frame clobbers and schedule block.

2019-06-03aarch64: emit .variant_pcs for aarch64_vector_pcs symbol referencesSzabolcs Nagy8-1/+191
A dynamic linker with lazy binding support may need to handle vector PCS function symbols specially, so an ELF symbol table marking was introduced for such symbols. Function symbol references and definitions that follow the vector PCS are marked in the generated assembly with .variant_pcs and then the STO_AARCH64_VARIANT_PCS st_other flag is set on the symbol in the object file. The marking is propagated to the dynamic symbol table by the static linker so a dynamic linker can handle such symbols specially. For this to work, the assembler, the static linker and the dynamic linker has to be updated on a system. Old assembler does not support the new .variant_pcs directive, so a toolchain with old binutils won't be able to compile code that references vector PCS symbols. gcc/ChangeLog: * config/aarch64/aarch64-protos.h (aarch64_asm_output_alias): Declare.

2019-06-03[AArch64] Emit TARGET_DOTPROD-specific sequence for <us>sadv16qiKyrylo Tkachov7-4/+97
Wilco pointed out that when the Dot Product instructions are available we can use them to generate an even more efficient expansion for the [us]sadv16qi optab. Instead of the current: uabdl2 v0.8h, v1.16b, v2.16b uabal v0.8h, v1.8b, v2.8b uadalp v3.4s, v0.8h we can generate: (1) mov v4.16b, 1 (2) uabd v0.16b, v1.16b, v2.16b (3) udot v3.4s, v0.16b, v4.16b Instruction (1) can be CSEd across multiple such expansions and even hoisted outside of loops, so when this sequence appears frequently back-to-back (like in x264_r) we essentially only have 2 instructions per sum. Also, the UDOT instruction does the byte-to-word accumulation in one step, which allows us to use the much simpler UABD instruction before it. This makes it a shorter and lower-latency sequence overall for targets that support it. * config/aarch64/iterators.md (MAX_OPP): New code attr. * config/aarch64/aarch64-simd.md (*aarch64_<su>abd<mode>_3): Rename to...

2019-05-31compiler: optimize append of makeIan Lance Taylor7-84/+251
The gc compiler recognizes append(s, make([]T, n)...), and generates code to directly zero the tail instead of allocating a new slice and copying. This CL lets the Go frontend do basically the same. The difficulty is that at the point we handle append, there may already be temporaries introduced (e.g. in order_evaluations), which makes it hard to find the append-of-make pattern. The compiler could "see through" the value of a temporary, but it is only safe to do if the temporary is not assigned multiple times. For this, we add tracking of assignments and uses for temporaries. This also helps in optimizing non-escape slice make. We already optimize non-escape slice make with constant len/cap to stack allocation. But it failed to handle things like f(make([]T, n)) (where the slice doesn't escape and n is constant), because of the temporary. With tracking of temporary assignments and uses, it can handle this now as well. Reviewed-on: https://go-review.googlesource.com/c/gofrontend/+/179597 From-SVN: r271822

2019-05-31New .md construct: define_insn_and_rewriteRichard Sandiford6-62/+249
Several SVE patterns need define_insn_and_splits that generate the same insn_code, but with different operands. That's probably a niche requirement, but it's cropping up often enough on the ACLE branch that I think it would be good to have a syntactic sugar for it. This patch therefore adds a new construct called define_insn_and_rewrite. It's basically a define_insn_and_split with an implicit split pattern, obtained by copying the insn pattern and replacing match_operands with match_dups and match_operators with match_op_dups. 2019-05-31 Richard Sandiford <richard.sandiford@arm.com> gcc/ * doc/md.texi: Document define_insn_and_rewrite. * rtl.def (DEFINE_INSN_AND_REWRITE): New rtx code. * gensupport.c (queue_elem): Update comment.
