The patch rewrites the content of doc.go file. The file describes some general rules of the mapping between Go assembly syntax and GNU syntax. And it gives some Go assembly examples and corresponding GNU assembly examples. The patch changes the doc.go to use standard doc comment format so that the link https://golang.org/cmd/internal/obj/arm64/ can display it. Assembly document framework is mainly contributed by Eric Fang <Eric.Fang@arm.com> Documentation work is contributed by Eric Fang and Fannie Zhang <Fannie.Zhang@arm.com> Change-Id: I8b3f6d6c6b91afdc2c44602e8f796beea905085e Reviewed-on: https://go-review.googlesource.com/102055Reviewed-by:

There are a bunch of places where we generate functions: equality and hash functions; method expression and promoted method wrappers; and print/delete wrappers for defer/go statements. This CL brings them in sync by: 1) Always using dclfunc and funcbody. Most were already using this, but makepartialcall needed some changes. 2) Removing duplicate types.Markdcl/types.Popdcl calls. These are already handled by dclfunc and funcbody. 3) Using structargs (already used by genwrapper) to construct new param/result lists from existing types. 4) Always accessing the parameter ONAME nodes through Field.Nname instead of poking into the ODCLFIELD. Also, since creating a slice of the entire parameter list is common, extract this out into a paramNnames helper function. 5) Add a Type.IsVariadic method to simplify identifying variadic function types. Passes toolstash-check -gcflags=-dwarf=false. DWARF output changes because using structargs in makepartialcall changes the generated parameter names.

By simply rearranging the logic, we avoid the overhead of a superfluous call to getsockopt. For, if p is already non empty, there's no point in having to check if we need to attach dummy payload. This has performance benefits when using send/recvmsg for high speed communications.

ARM64 supports load/store instructions with a memory operand that the address is calculated by base register + index register. In this CL, 1. Some rules are added to the compile's ARM64 backend to emit such efficient instructions. 2. A wrong rule of load combination is fixed.

Disasm.Decode currently always appends a tab to the formatted instruction, although not to any relocations after it. Decode has two clients: objdump and pprof. pprof emits plain text, so it would be better not to have a trailing tab. objdump wants the trailing tab for text/tabwriter, but it is easy to add that to the Fprintf call. Shifting the responsibility for the trailing tab to the caller simplifies the code, increases correctness, and slightly improves performance by reducing and coalescing string concatenations.

VDSO calls do manual stack alignment, which doesn't get tracked in the pcsp table. Without accurate pcsp information, backtracing them is dangerous, and causes a crash in the SIGPROF handler.

Some syscall structures used by crypto/x509 have uintptr fields that store pointers. These pointers are set with a pointer to another Go structure. But the pointers are not visible by garbage collector, and GC does not update the fields after they were set. So when structure with invalid uintptr pointers passed to Windows, we get memory corruption. This CL introduces CertInfo, CertTrustListInfo and CertRevocationCrlInfo types. It uses pointers to new types instead of uintptr in CertContext, CertSimpleChain and CertRevocationInfo. CertRevocationInfo, CertChainPolicyPara and CertChainPolicyStatus types have uintptr field that can be pointer to many different things (according to Windows API). So this CL introduces Pointer type to be used for those cases. As suggested by Austin Clements.

The escape analysis models the flow of "content" of X with a level of "indirection" (OIND node) of X. This content can be pointer dereference, or slice/string element. For the latter case, the type of the OIND node should be the element type of the slice/string. This CL fixes this. In particular, this matters when the element type is pointerless, where the data flow should not cause any escape. Fixes #15730.

By using local variables and assigning them back to decompressor at the end of huffSym, we allow compiler to keep them in registers and avoid reloading/storing them repeatedly. To archive this, moreBits was inlined and specialized to work with local variables. Also move EOF error conversion to helper function, to make inlined part of moreBits more readable. Together this results in nice speed-up: name old time/op new time/op delta Decode/Digits/Huffman/1e4-6 278µs ± 1% 240µs ± 2% -13.72% (p=0.000 n=10+10) Decode/Digits/Huffman/1e5-6 2.38ms ± 1% 2.05ms ± 1% -14.12% (p=0.000 n=10+10) Decode/Digits/Huffman/1e6-6 23.4ms ± 1% 19.9ms ± 0% -14.69% (p=0.000 n=9+9) Decode/Digits/Speed/1e4-6 280µs ± 2% 254µs ± 1% -9.28% (p=0.000 n=10+9) Decode/Digits/Speed/1e5-6 2.53ms ± 1% 2.35ms ± 1% -7.17% (p=0.000 n=10+10) Decode/Digits/Speed/1e6-6 24.8ms ± 1% 23.0ms ± 1% -7.22% (p=0.000 n=10+10) Decode/Digits/Default/1e4-6 281µs ± 2% 259µs ± 3% -8.03% (p=0.000 n=10+10) Decode/Digits/Default/1e5-6 2.45ms ± 1% 2.30ms ± 1% -6.15% (p=0.000 n=10+10) Decode/Digits/Default/1e6-6 24.1ms ± 1% 22.6ms ± 0% -6.31% (p=0.000 n=9+9) Decode/Digits/Compression/1e4-6 279µs ± 2% 261µs ± 2% -6.53% (p=0.000 n=8+9) Decode/Digits/Compression/1e5-6 2.44ms ± 1% 2.30ms ± 1% -5.72% (p=0.000 n=10+9) Decode/Digits/Compression/1e6-6 24.0ms ± 1% 22.6ms ± 0% -6.10% (p=0.000 n=10+9) Decode/Twain/Huffman/1e4-6 316µs ± 2% 267µs ± 3% -15.30% (p=0.000 n=9+10) Decode/Twain/Huffman/1e5-6 2.62ms ± 0% 2.22ms ± 0% -15.24% (p=0.000 n=10+10) Decode/Twain/Huffman/1e6-6 25.7ms ± 1% 21.8ms ± 0% -15.19% (p=0.000 n=10+10) Decode/Twain/Speed/1e4-6 290µs ± 1% 264µs ± 2% -9.17% (p=0.000 n=9+10) Decode/Twain/Speed/1e5-6 2.35ms ± 1% 2.13ms ± 1% -9.74% (p=0.000 n=9+10) Decode/Twain/Speed/1e6-6 22.9ms ± 0% 20.7ms ± 0% -9.68% (p=0.000 n=10+9) Decode/Twain/Default/1e4-6 270µs ± 2% 252µs ± 2% -6.67% (p=0.000 n=9+10) Decode/Twain/Default/1e5-6 2.02ms ± 1% 1.84ms ± 1% -8.85% (p=0.000 n=10+10) Decode/Twain/Default/1e6-6 19.1ms ± 0% 17.5ms ± 1% -8.73% (p=0.000 n=9+10) Decode/Twain/Compression/1e4-6 272µs ± 1% 250µs ± 4% -8.20% (p=0.000 n=9+10) Decode/Twain/Compression/1e5-6 2.01ms ± 0% 1.84ms ± 1% -8.57% (p=0.000 n=9+10) Decode/Twain/Compression/1e6-6 19.1ms ± 0% 17.4ms ± 1% -8.75% (p=0.000 n=9+10) name old speed new speed delta Decode/Digits/Huffman/1e4-6 35.9MB/s ± 1% 41.7MB/s ± 2% +15.91% (p=0.000 n=10+10) Decode/Digits/Huffman/1e5-6 41.9MB/s ± 1% 48.8MB/s ± 1% +16.44% (p=0.000 n=10+10) Decode/Digits/Huffman/1e6-6 42.8MB/s ± 1% 50.2MB/s ± 0% +17.22% (p=0.000 n=9+9) Decode/Digits/Speed/1e4-6 35.7MB/s ± 2% 39.4MB/s ± 1% +10.22% (p=0.000 n=10+9) Decode/Digits/Speed/1e5-6 39.6MB/s ± 1% 42.6MB/s ± 1% +7.73% (p=0.000 n=10+10) Decode/Digits/Speed/1e6-6 40.3MB/s ± 1% 43.4MB/s ± 1% +7.78% (p=0.000 n=10+10) Decode/Digits/Default/1e4-6 35.6MB/s ± 2% 38.7MB/s ± 2% +8.74% (p=0.000 n=10+10) Decode/Digits/Default/1e5-6 40.9MB/s ± 1% 43.6MB/s ± 1% +6.55% (p=0.000 n=10+10) Decode/Digits/Default/1e6-6 41.5MB/s ± 1% 44.3MB/s ± 0% +6.73% (p=0.000 n=9+9) Decode/Digits/Compression/1e4-6 35.8MB/s ± 2% 38.3MB/s ± 2% +6.99% (p=0.000 n=8+9) Decode/Digits/Compression/1e5-6 40.9MB/s ± 1% 43.4MB/s ± 1% +6.07% (p=0.000 n=10+9) Decode/Digits/Compression/1e6-6 41.6MB/s ± 1% 44.3MB/s ± 0% +6.49% (p=0.000 n=10+9) Decode/Twain/Huffman/1e4-6 31.7MB/s ± 2% 37.4MB/s ± 3% +18.08% (p=0.000 n=9+10) Decode/Twain/Huffman/1e5-6 38.2MB/s ± 0% 45.0MB/s ± 0% +17.97% (p=0.000 n=10+10) Decode/Twain/Huffman/1e6-6 38.9MB/s ± 1% 45.9MB/s ± 0% +17.90% (p=0.000 n=10+10) Decode/Twain/Speed/1e4-6 34.5MB/s ± 1% 38.0MB/s ± 2% +10.11% (p=0.000 n=9+10) Decode/Twain/Speed/1e5-6 42.5MB/s ± 1% 47.0MB/s ± 1% +10.79% (p=0.000 n=9+10) Decode/Twain/Speed/1e6-6 43.7MB/s ± 0% 48.3MB/s ± 0% +10.72% (p=0.000 n=10+9) Decode/Twain/Default/1e4-6 37.1MB/s ± 2% 39.8MB/s ± 2% +7.15% (p=0.000 n=9+10) Decode/Twain/Default/1e5-6 49.5MB/s ± 1% 54.3MB/s ± 1% +9.71% (p=0.000 n=10+10) Decode/Twain/Default/1e6-6 52.3MB/s ± 0% 57.3MB/s ± 1% +9.57% (p=0.000 n=9+10) Decode/Twain/Compression/1e4-6 36.7MB/s ± 1% 40.0MB/s ± 4% +8.96% (p=0.000 n=9+10) Decode/Twain/Compression/1e5-6 49.8MB/s ± 0% 54.5MB/s ± 1% +9.38% (p=0.000 n=9+10) Decode/Twain/Compression/1e6-6 52.3MB/s ± 0% 57.3MB/s ± 1% +9.58% (p=0.000 n=9+10) Change-Id: Iabfd285535ddb210f7f48f33317c6463b5532400 Reviewed-on: https://go-review.googlesource.com/102235 Run-TryBot: Ilya Tocar <ilya.tocar@intel.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by:

CL 106735 changed to the new softfloat support on GOARM=5. ARM assembly code that uses FP instructions not guarded on GOARM, if any, will break. The easiest way to fix is probably to use Go implementation on GOARM=5, like MOVB runtime·goarm(SB), R11 CMP $5, R11 BEQ arm5 ... FP instructions ...

Say "offset too large" instead of "invalid instruction" when assembling for AMD64. GOARCH=386 already reports error correctly.
