cmd/compile: incorporate inlined function names into closure naming
In Go 1.17, cmd/compile gained the ability to inline calls to functions that contain function literals (aka "closures"). This was implemented by duplicating the function literal body and emitting a second LSym, because in general it might be optimized better than the original function literal. However, the second LSym was named simply as any other function literal appearing literally in the enclosing function would be named. E.g., if f has a closure "f.funcX", and f is inlined into g, we would create "g.funcY" (N.B., X and Y need not be the same.). Users then have no idea this function originally came from f. With this CL, the inlined call stack is incorporated into the clone LSym's name: instead of "g.funcY", it's named "g.f.funcY". In the future, it seems desirable to arrange for the clone's name to appear exactly as the original name, so stack traces remain the same as when -l or -d=inlfuncswithclosures are used. But it's unclear whether the linker supports that today, or whether any downstream tooling would be confused by this. Updates #60324.

cmd/compile: make memcombine pass a bit more robust to reassociation of exprs
Be more liberal about expanding the OR tree. Handle any tree shape instead of a fully left or right associative tree. Also remove tail feature, it isn't ever needed.

cmd/compile: update rules to generate more prefixed instructions
This modifies some existing rules to allow more prefixed instructions to be generated when using GOPPC64=power10. Some rules also check if PCRel is available, which is currently supported for linux/ppc64le and linux/ppc64 (internal linking only). Prior to p10, DS-offset loads and stores had a 16 bit size limit for the offset field. If the offset of the data for load or store was beyond this range then an indexed load or store would be selected by the rules. In p10 the assembler can generate prefixed instructions in this case, but does not if an indexed instruction was selected during the lowering pass. This allows many more cases to use prefixed loads or stores, reducing function sizes and improving performance in some cases where the code change happens in key loops. For example in strconv BenchmarkAppendQuoteRune before: 12c5e4: 15 00 10 06 pla r10,1425660 12c5e8: fc c0 40 39 12c5ec: 00 00 6a e8 ld r3,0(r10) 12c5f0: 10 00 aa e8 ld r5,16(r10) After this change: 12a828: 15 00 10 04 pld r3,1433272 12a82c: b8 de 60 e4 12a830: 15 00 10 04 pld r5,1433280 12a834: c0 de a0 e4 Performs better in the second case. A testcase was added to verify that the rules correctly select a load or store based on the offset and whether power10 or earlier.

internal/testdir: move to cmd/internal/testdir
The effect and motivation is for the test to be selected when doing 'go test cmd' and not when doing 'go test std' since it's primarily about testing the Go compiler and linker. Other than that, it's run by all.bash and 'go test std cmd' as before. For #56844. Fixes #60059.

test: add memcombine testcases for ppc64
Thanks to the recent addition of the memcombine pass, the ppc64 ports now have the memcombine optimizations. Previously in PPC64.rules, the memcombine rules were only added for ppc64le targets due to the significant increase in size of the rewritePPC64.go file when those rules were added. The ppc64 and ppc64le rules had to be different because of the byte order due to endianness differences. This enables the memcombine tests to be run on ppc64 as well as ppc64le.

cmd/compile: optimize cmp to cmn under conditions < and >= on arm64
Under the right conditions we can optimize cmp comparisons to cmn comparisons, such as: func foo(a, b int) int { var c int if a + b < 0 { c = 1 } return c } Previously it's compiled as: ADD R1, R0, R1 CMP $0, R1 CSET LT, R0 With this CL it's compiled as: CMN R1, R0 CSET MI, R0 Here we need to pay attention to the overflow situation of a+b, the MI flag means N==1, which doesn't honor the overflow flag V, its value depends only on the sign of the result. So it has the same semantic of the Go code, so it's correct. Similarly, this CL also optimizes the case of >= comparison using the PL conditional flag.

cmd/compile: fix incorrect truncating when converting CMP to TST on arm64
CL 420434 optimized CMP into TST in some situations, but it has a bug, these four rules are not correct: (LessThan (CMPWconst [0] x:(ANDconst [c] y))) && x.Uses == 1 => (LessThan (TSTconst [c] y)) (LessEqual (CMPWconst [0] x:(ANDconst [c] y))) && x.Uses == 1 => (LessEqual (TSTconst [c] y)) (GreaterThan (CMPWconst [0] x:(ANDconst [c] y))) && x.Uses == 1 => (GreaterThan (TSTconst [c] y)) (GreaterEqual (CMPWconst [0] x:(ANDconst [c] y))) && x.Uses == 1 => (GreaterEqual (TSTconst [c] y)) But due to the existence of this rule (LessThan (CMPWconst [0] x:(ANDconst [c] y))) && x.Uses == 1 => (LessThan (TSTWconst [int32(c)] y)), the above rules have never been fired. This CL corrects them as: (LessThan (CMPconst [0] x:(ANDconst [c] y))) && x.Uses == 1 => (LessThan (TSTconst [c] y)) (LessEqual (CMPconst [0] x:(ANDconst [c] y))) && x.Uses == 1 => (LessEqual (TSTconst [c] y)) (GreaterThan (CMPconst [0] x:(ANDconst [c] y))) && x.Uses == 1 => (GreaterThan (TSTconst [c] y)) (GreaterEqual (CMPconst [0] x:(ANDconst [c] y))) && x.Uses == 1 => (GreaterEqual (TSTconst [c] y)) Change-Id: I7d60bcc9a266ee58388baeaab9f493b57cf1ad55 Reviewed-on: https://go-review.googlesource.com/c/go/+/473617 TryBot-Result: Gopher Robot <gobot@golang.org> Reviewed-by: Cherry Mui <cherryyz@google.com> Reviewed-by: Dmitri Shuralyov <dmitshur@google.com> Run-TryBot: Eric Fang <eric.fang@arm.com> |

cmd/dist, test: convert test/run.go runner to a cmd/go test
As motivated on the issue, we want to move the functionality of the run.go program to happen via a normal go test. Each .go test case in the GOROOT/test directory gets a subtest, and cmd/go's support for parallel test execution replaces run.go's own implementation thereof. The goal of this change is to have fairly minimal and readable diff while making an atomic changeover. The working directory is modified during the test execution to be GOROOT/test as it was with run.go, and most of the test struct and its run method are kept unchanged. The next CL in the stack applies further simplifications and cleanups that become viable. There's no noticeable difference in test execution time: it takes around 60-80 seconds both before and after on my machine. Test caching, which the previous runner lacked, can shorten the time significantly. For #37486. Fixes #56844.

cmd/compile: use zero constants in comparisons where possible
Some integer comparisons with 1 and -1 can be rewritten as comparisons with 0. For example, x < 1 is equivalent to x <= 0. This is an advantageous transformation on riscv64 because comparisons with zero do not require a constant to be loaded into a register. Other architectures will likely benefit too and the transformation is relatively benign on architectures that do not benefit.

cmd/compile: add rules to emit SETBC/R instructions on power10
This CL adds rules that replaces instances of ISEL that produce a boolean result based on a condition register by SETBC/SETBCR operations. On Power10 these are convereted to SETBC/SETBCR instructions that use one register instead of 3 registers conventionally used by ISEL and hence reduces register pressure. On loops written specifically to exercise such instances of ISEL extensively, a performance improvement of 2.5% is seen on Power10. Also added verification tests to verify correct generation of SETBC/SETBCR instructions on Power10.

cmd/compile: schedule values with no in-block uses later
When scheduling a block, deprioritize values whose results aren't used until subsequent blocks. For #58166, this has the effect of pushing the induction variable increment to the end of the block, past all the other uses of the pre-incremented value. Do this only with optimizations on. Debuggers have a preference for values in source code order, which this CL can degrade.

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.

Manually consolidate the remaining ppc64/ppc64le test which are not so trivial to automatically merge.

Use a small python script to consolidate duplicate ppc64/ppc64le tests into a single ppc64x codegen test.

test/codegen: accept ppc64x as alias for ppc64le and ppc64 arches
This helps simplify the noise when adding ppc codegen tests. ppc64x is used in other places to indicate something which runs on either endian. This helps cleanup existing codegen tests which are mostly identical between endian variants. condmove tests are converted as an example.

internal/abi,runtime: refactor map constants into one place

This makes it much easier to change the size of map buckets, and hopefully provides pointers to all the code that in some way depends on details of map layout.

cmd/compile: AMD64v3 remove unnecessary TEST comparision in isPowerOfTwo
With GOAMD64=V3 the canonical isPowerOfTwo function: func isPowerOfTwo(x uintptr) bool { return x&(x-1) == 0 } Used to compile to: temp := BLSR(x) // x&(x-1) flags = TEST(temp, temp) return flags.zf However the blsr instruction already set ZF according to the result. So we can remove the TEST instruction if we are just checking ZF. Such as in multiple pieces of code around memory allocations. This make the code smaller and faster.

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®exp=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.

cmd/compile: add anchored version of SP
The SPanchored opcode is identical to SP, except that it takes a memory argument so that it (and more importantly, anything that uses it) must be scheduled at or after that memory argument. This opcode ensures that a LEAQ of a variable gets scheduled after the corresponding VARDEF for that variable. This may lead to less CSE of LEAQ operations. The effect is very small. The go binary is only 80 bytes bigger after this CL. Usually LEAQs get folded into load/store operations, so the effect is only for pointerful types, large enough to need a duffzero, and have their address passed somewhere. Even then, usually the CSEd LEAQs will be un-CSEd because the two uses are on different sides of a function call and the LEAQ ends up being rematerialized at the second use anyway.
