cmd/compile: intrinsify math/bits/ReverseBytes{32|64} for 386
The BSWAPL instruction is supported in i486 and newer. https://github.com/golang/go/wiki/MinimumRequirements#386 says we support "All Pentium MMX or later". The Pentium is also referred to as i586, so that we are safe with these instructions.

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: intrinsify math/bits/ReverseBytes{16|32|64} for ppc64/power10
This change intrinsifies ReverseBytes{16|32|64} by generating the
corresponding new instructions in Power10: brh, brd and brw and
adds a verification test for the same.
On Power 9 and 8, the .go code performs optimally as it is.
Performance improvement seen on Power10:
ReverseBytes32 1.38ns ± 0% 1.18ns ± 0% -14.2
ReverseBytes64 1.52ns ± 0% 1.11ns ± 0% -26.87

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. Fixes #58166 Fixes #57976 Change-Id: I40d5885c661b142443c6d4702294c8abe8026c4f Reviewed-on: https://go-review.googlesource.com/c/go/+/463751 Run-TryBot: Keith Randall <khr@golang.org> Reviewed-by: David Chase <drchase@google.com> Reviewed-by: Keith Randall <khr@google.com> TryBot-Result: Gopher Robot <gobot@golang.org> |

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.

test/codegen: merge identical ppc64 and ppc64le tests
Manually consolidate the remaining ppc64/ppc64le test which are not so trivial to automatically merge.

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
Previously TryBot-tested with bucket bits = 4. Also tested locally with bucket bits = 5. 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.

cmd/compile: merge zero constant ISEL in PPC64 lateLower pass
Add a new SSA opcode ISELZ, similar to ISELB to represent a select of value or 0. Then, merge candidate ISEL opcodes inside the late lower pass. This avoids complicating rules within the the lower pass.

cmd/compile/internal/ssa: re-adjust CarryChainTail scheduling priority
This needs to be as low as possible while not breaking priority assumptions of other scores to correctly schedule carry chains. Prior to the arm64 changes, it was set below ReadTuple. At the time, this prevented the MulHiLo implementation on PPC64 from occluding the scheduling of a full carry chain. Memory scores can also prevent better scheduling, as can be observed with crypto/internal/edwards25519/field.feMulGeneric.

cmd/compile: add rule for post-decomposed growslice optimization
The recently added rule only works before decomposing slices. Add a rule that works after decomposing slices. The reason we need the latter is because although the length may be a constant, it can be hidden inside a slice that is not constant (its pointer or capacity might be changing). By applying this optimization after decomposing slices, we can find more cases where it applies.

cmd/compile: add late lower pass for last rules to run
Usually optimization rules have corresponding priorities, some need to
be run first, some run next, and some run last, which produces the best
code. But currently our optimization rules have no priority, this CL
adds a late lower pass that runs those rules that need to be run at last,
such as split unreasonable constant folding. This pass can be seen as
the second round of the lower pass.
For example:
func foo(a, b uint64) uint64 {
d := a+0x1234568
d1 := b+0x1234568
return d&d1
}
The code generated by the master branch:
0x0004 00004 ADD $19088744, R0, R2 // movz+movk+add
0x0010 00016 ADD $19088744, R1, R1 // movz+movk+add
0x001c 00028 AND R1, R2, R0
This is because the current constant folding optimization rules do not
take into account the range of constants, causing the constant to be
loaded repeatedly. This CL splits these unreasonable constants folding
in the late lower pass. With this CL the generated code:
0x0004 00004 MOVD $19088744, R2 // movz+movk
0x000c 00012 ADD R0, R2, R3
0x0010 00016 ADD R1, R2, R1
0x0014 00020 AND R1, R3, R0
This CL also adds constant folding optimization for ADDS instruction.
In addition, in order not to introduce the codegen regression, an
optimization rule is added to change the addition of a negative number
into a subtraction of a positive number.

cmd/compile/internal/noder: allow OCONVNOP for identical iface conversions
In go.dev/cl/421821, I included a hack to force OCONVNOP back to OCONVIFACE for conversions involving shape types and non-empty interfaces. The comment correctly noted that this was only needed for conversions between non-identical types, but the code was conservative and applied to even conversions between identical types. This CL adds an extra bool to record whether the conversion is between identical types, so we can keep OCONVNOP instead of forcing back to OCONVIFACE. This has a small improvement to generated code, because we no longer need a convI2I call (as demonstrated by codegen/ifaces.go). But more usefully, this is relevant to pruning unnecessary itab slots in runtime dictionaries (next CL).

cmd/compile: new inline heuristic for struct compares
This CL changes the heuristic used to determine whether we can inline a
struct equality check or if we must generate a function and call that
function for equality.
The old method was to count struct fields, but this can lead to poor
in lining decisions. We should really be determining the cost of the
equality check and use that to determine if we should inline or generate
a function.
The new benchmark provided in this CL returns the following when compared
against tip:
```

cmd/compile: deadcode for LoweredMuluhilo on riscv64
This is a follow up of CL 425101 on RISCV64. According to RISCV Volume 1, Unprivileged Spec v. 20191213 Chapter 7.1: If both the high and low bits of the same product are required, then the recommended code sequence is: MULH[[S]U] rdh, rs1, rs2; MUL rdl, rs1, rs2 (source register specifiers must be in same order and rdh cannot be the same as rs1 or rs2). Microarchitectures can then fuse these into a single multiply operation instead of performing two separate multiplies. So we should not split Muluhilo to separate instructions.

cmd/internal/obj/arm64: remove the transition from $0 to ZR
Previously we convert $0 to the ZR register for some reasons, which causes two problems: 1. Confusion, the special case of the ZR register needs to be considered when dealing with constants. For encoding, some places we encode ZR, and some places we encode $0, although we have converted $0 to ZR. 2. Unexpected instruction format. All instructions that support ZR register operands can be replaced by $0. This patch removes this conversion. Note that this patch may cause previously unintendedly supported instruction formats to no longer be supported.

cmd/compile: stop using VARKILL
With the introduction of stack objects, VARKILL information is no longer needed. With stack objects, an object is dead when there are no more static references to it, and the stack scanner can't find any live pointers to it. VARKILL information isn't used to establish live ranges for address-taken variables any more. In effect, the last static reference *is* the VARKILL, and there's an additional dynamic liveness check during stack scanning. Next CL will actually rip out the VARKILL opcodes.

all: use ":" for compiler generated symbols
As it can't appear in user package paths. There is a hack for handling "go:buildid" and "type:*" on windows/386. Previously, windows/386 requires underscore prefix on external symbols, but that's only applied for SHOSTOBJ/SUNDEFEXT or cgo export symbols. "go.buildid" is STEXT, "type.*" is STYPE, thus they are not prefixed with underscore. In external linking mode, the external linker can't resolve them as external symbols. But we are lucky that they have "." in their name, so the external linker see them as Forwarder RVA exports. See: - https://docs.microsoft.com/en-us/windows/win32/debug/pe-format#export-address-table - https://sourceware.org/git/?p=binutils-gdb.git;a=blob;f=ld/pe-dll.c;h=e7b82ba6ffadf74dc1b9ee71dc13d48336941e51;hb=HEAD#l972) This CL changes "." to ":" in symbols name, so theses symbols can not be found by external linker anymore. So a hacky way is adding the underscore prefix for these 2 symbols. I don't have enough knowledge to verify whether adding the underscore for all STEXT/STYPE symbols are fine, even if it could be, that would be done in future CL.

cmd/compile: fix confusion with ANDCCconst in PPC64 rules
Currently there is a an ANDconst and an ANDCCconst op in PPC64, which is confusing since they map onto the same instruction. One of these ops sets the result of the AND operation, and the other sets the flag (condition register). This converts ANDCCconst into an op with the 2 expected results: the integer result of the AND and the flag setting. The ANDconst op has been removed. Note that in the PPC64 ISA the only variation of the 'and immediate' is the one that sets the condition bit, which probably led to the original (confusing) implementation. This also adds a few rules to improve the use of ANDCCconst with ISELB and some testcases to verify those improvements.

cmd/compile: optimize unsafe.Slice generated code
We don't need a multiply when the element type is size 0 or 1. The panic functions don't return, so we don't need any post-call code (register restores, etc.).
