Lynn Boger	ebe49f98c8	cmd/compile: inline constant sized memclrNoHeapPointers calls on PPC64 Update the function isInlinableMemclr for ppc64 and ppc64le to enable inlining for the constant sized cases < 512. Larger cases can use dcbz which performs better but requires alignment checking so it is best to continue using memclrNoHeapPointers for those cases.

Jakub Ciolek	1fc585dc2f	cmd/compile: inline known-size memclrNoHeapPointers calls This patch rewrites known-size calls to memclrNoHeapPointers with an OpZero. This significantly improves performance and lets some clears get DSE'd. One of the cases where this applies is zeroing a known-size array, example: var x [256]int8 ... for a := range x { x[a] = 0 } Other cases can be found in the runtime itself where memclrNoHeapPointers is sometimes directly invoked with a constant. It seems that for some sized-clears on some architectures (AMD64, maybe others) the memcrlNoHeapPointers is more performant than OpZero. See the issue #56997 for more details.

Jorropo	fc814056aa	cmd/compile: rewrite empty makeslice to zerobase pointer make\(\[\][a-zA-Z0-9]+, 0\) is seen 52 times in the go source. And at least 391 times on internet: https://grep.app/search?q=make%5C%28%5C%5B%5C%5D%5Ba-zA-Z0-9%5D%2B%2C%200%5C%29&regexp=true This used to compile to calling runtime.makeslice. However we can copy what we do for []T{}, just use a zerobase pointer. On my machine this is 10x faster (from 3ns to 0.3ns). Note that an empty loop also runs in 0.3ns, so this really is free when you count superscallar execution.

Cherry Zhang	263e13d1f7	test: make codegen tests work with both ABIs Some codegen tests were written with the assumption that arguments and results are in memory, and with a specific stack layout. With the register ABI, the assumption is no longer true. Adjust the tests to work with both cases. - For tests expecting in memory arguments/results, change to use global variables or memory-assigned argument/results. - Allow more registers. E.g. some tests expecting register names contain only letters (e.g. AX), but it can also contain numbers (e.g. R10). - Some instruction selection changes when operate on register vs. memory, e.g. ADDQ vs. LEAQ, MOVB vs. MOVL. Accept both. TODO: mathbits.go and memops.go still need fix.

Paul E. Murphy	7615b20d06	cmd/compile: generate subfic on ppc64 This merges an lis + subf into subfic, and for 32b constants lwa + subf into oris + ori + subf. The carry bit is no longer used in code generation, therefore I think we can clobber it as needed. Note, lowered borrow/carry arithmetic is self-contained and thus is not affected. A few extra rules are added to ensure early transformations to SUBFCconst don't trip up earlier rules, fold constant operations, or otherwise simplify lowering. Likewise, tests are added to ensure all rules are hit. Generic constant folding catches trivial cases, however some lowering rules insert arithmetic which can introduce new opportunities (e.g BitLen or Slicemask). I couldn't find a specific benchmark to demonstrate noteworthy improvements, but this is generating subfic in many of the default bent test binaries, so we are at least saving a little code space.

LE Manh Cuong	ec4e8517cd	cmd/compile: support more length types for slice extension optimization golang.org/cl/109517 optimized the compiler to avoid the allocation for make in append(x, make([]T, y)...). This was only implemented for the case that y has type int. This change extends the optimization to trigger for all integer types where the value is known at compile time to fit into an int. name old time/op new time/op delta ExtendInt-12 106ns ± 4% 106ns ± 0% ~ (p=0.351 n=10+6) ExtendUint64-12 1.03µs ± 5% 0.10µs ± 4% -90.01% (p=0.000 n=9+10) name old alloc/op new alloc/op delta ExtendInt-12 0.00B 0.00B ~ (all equal) ExtendUint64-12 13.6kB ± 0% 0.0kB -100.00% (p=0.000 n=10+10) name old allocs/op new allocs/op delta ExtendInt-12 0.00 0.00 ~ (all equal) ExtendUint64-12 1.00 ± 0% 0.00 -100.00% (p=0.000 n=10+10) Updates #29785 Change-Id: Ief7760097c285abd591712da98c5b02bc3961fcd Reviewed-on: https://go-review.googlesource.com/c/go/+/182559 Run-TryBot: Cuong Manh Le <cuong.manhle.vn@gmail.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Keith Randall <khr@golang.org>	2019-09-17 17:18:17 +00:00
Keith Randall	933e34ac99	cmd/compile: treat slice pointers as non-nil var a []int = ... p := &a[0] _ = *p We don't need to nil check on the 3rd line. If the bounds check on the 2nd line passes, we know p is non-nil. We rely on the fact that any cap>0 slice has a non-nil pointer as its pointer to the backing array. This is true for all safely-constructed slices, and I don't see any reason why someone would violate this rule using unsafe.
