When we need to generate a call to _cgoCheckPointer, we need to type assert the result back to the desired type. That is harder when the type is unsafe.Pointer, as the package can have values of unsafe.Pointer types without actually importing unsafe, by mixing C void* and :=. We used to handle this by generating a special function for each needed type, and defining that function in a separate file where we did import unsafe. Simplify the code by not generating those functions, but instead just import unsafe under the alias _cgo_unsafe. This is a simplification step toward a fix for issue #16591.

Previously, we used OKEY nodes to represent keyed struct literal elements. The field names were represented by an ONAME node, but this is clumsy because it's the only remaining case where ONAME was used to represent a bare identifier and not a variable. This CL introduces a new OSTRUCTKEY node op for use in struct literals. These ops instead store the field name in the node's own Sym field. This is similar in spirit to golang.org/cl/20890. Significant reduction in allocations for struct literal heavy code like package unicode: name old time/op new time/op delta Template 345ms ± 6% 341ms ± 6% ~ (p=0.141 n=29+28) Unicode 200ms ± 9% 184ms ± 7% -7.77% (p=0.000 n=29+30) GoTypes 1.04s ± 3% 1.05s ± 3% ~ (p=0.096 n=30+30) Compiler 4.47s ± 9% 4.49s ± 6% ~ (p=0.890 n=29+29) name old user-ns/op new user-ns/op delta Template 523M ±13% 516M ±17% ~ (p=0.400 n=29+30) Unicode 334M ±27% 314M ±30% ~ (p=0.093 n=30+30) GoTypes 1.53G ±10% 1.52G ±10% ~ (p=0.572 n=30+30) Compiler 6.28G ± 7% 6.34G ±11% ~ (p=0.300 n=30+30) name old alloc/op new alloc/op delta Template 44.5MB ± 0% 44.4MB ± 0% -0.35% (p=0.000 n=27+30) Unicode 39.2MB ± 0% 34.5MB ± 0% -11.79% (p=0.000 n=26+30) GoTypes 125MB ± 0% 125MB ± 0% -0.12% (p=0.000 n=29+30) Compiler 515MB ± 0% 515MB ± 0% -0.10% (p=0.000 n=29+30) name old allocs/op new allocs/op delta Template 426k ± 0% 424k ± 0% -0.39% (p=0.000 n=29+30) Unicode 374k ± 0% 323k ± 0% -13.67% (p=0.000 n=29+30) GoTypes 1.21M ± 0% 1.21M ± 0% -0.14% (p=0.000 n=29+29) Compiler 4.40M ± 0% 4.39M ± 0% -0.13% (p=0.000 n=29+30) Passes toolstash/buildall.

This CL introduces first test for readConsole. And new test discovered couple of problems with readConsole. Console characters consist of multiple bytes each, but byte blocks returned by syscall.ReadFile have no character boundaries. Some multi-byte characters might start at the end of one block, and end at the start of next block. readConsole feeds these blocks to syscall.MultiByteToWideChar to convert them into utf16, but if some multi-byte characters have no ending or starting bytes, the syscall.MultiByteToWideChar might get confused. Current version of syscall.MultiByteToWideChar call will make syscall.MultiByteToWideChar ignore all these not complete multi-byte characters. The CL solves this issue by changing processing from "randomly sized block of bytes at a time" to "one multi-byte character at a time". New readConsole code calls syscall.ReadFile to get 1 byte first. Then it feeds this byte to syscall.MultiByteToWideChar. The new syscall.MultiByteToWideChar call uses MB_ERR_INVALID_CHARS flag to make syscall.MultiByteToWideChar return error if input is not complete character. If syscall.MultiByteToWideChar returns correspondent error, we read another byte and pass 2 byte buffer into syscall.MultiByteToWideChar, and so on until success. Old readConsole code would also sometimes return no data if user buffer was smaller then uint16 size, which would confuse callers that supply 1 byte buffer. This CL fixes that problem too.

Some of the branch instructions (BEQ, BNE, BLT, etc.) accept all the valid CR values as operands, but the CR register value is not parsed and not put into the instruction, so that CR0 is always used regardless of what was specified on the instruction. For example BEQ CR2,label becomes beq cr0,label. This adds the change to the PPC64 assembler to recognize the CR value and set the approppriate field in the instruction so the correct CR is used. This also adds some general comments on the branch instruction BC and its operand values.

To compile: m[k] = v instead of: mapassign(maptype, m, &k, &v), do do: *mapassign(maptype, m, &k) = v mapassign returns a pointer to the value slot in the map. It is just like mapaccess except that it will allocate a new slot if k is not already present in the map. This makes map accesses faster but potentially larger (codewise). It is faster because the write into the map is done when the compiler knows the concrete type, so it can be done with a few store instructions instead of calling typedmemmove. We also potentially avoid stack temporaries to hold v. The code can be larger when the map has pointers in its value type, since there is a write barrier call in addition to the mapassign call. That makes the code at the callsite a bit bigger (go binary is 0.3% bigger). This CL is in preparation for doing operations like m[k] += v with only a single runtime call. That will roughly double the speed of such operations.

We will need OpenSSL 1.1.0 in order to test some of the features expected for Go 1.8. However, 1.1.0 also disables (by default) some things that we still want to test, such as RC4, 3DES and SSLv3. Thus developers wanting to update the crypto/tls test data will need to build OpenSSL from source. This change updates the test data with transcripts generated by 1.1.0 (in order to reduce future diffs) and also causes a banner to be printed if 1.1.0 is not used when updating. (The test for an ALPN mismatch is removed because OpenSSL now terminates the connection with a fatal alert if no known ALPN protocols are offered. There's no point testing against this because it's an OpenSSL behaviour.)

* Assert that the format is GNU. Both GNU and STAR have some form of sparse file support with incompatible header structures. Worse yet, both formats use the 'S' type flag to indicate the presence of a sparse file. As such, we should check the format (based on magic numbers) and fail early. * Move realsize parsing logic into readOldGNUSparseMap. This is related to the sparse parsing logic and belongs here. * Fix the termination condition for parsing sparse fields. The termination condition for reading the sparse fields is to simply check if the first byte of the offset field is NULL. This does not seem to be documented in the GNU manual, but this is the check done by the both the GNU and BSD implementations: http://git.savannah.gnu.org/cgit/tar.git/tree/src/sparse.c?id=9a33077a7b7ad7d32815a21dee54eba63b38a81c#n731 https://github.com/libarchive/libarchive/blob/1fa9c7bf90f0862036a99896b0501c381584451a/libarchive/archive_read_support_format_tar.c#L2207 * Fix the parsing of sparse fields to use parseNumeric. This is what GNU and BSD do. The previous two links show that GNU and BSD both handle base-256 and base-8. * Detect truncated streams. The call to io.ReadFull does not check if the error is io.EOF. Getting io.EOF in this method is never okay and should always be converted to io.ErrUnexpectedEOF. * Simplify the function. The logic is essentially a do-while loop so we can remove some redundant code. Change-Id: Ib2f601b1a283eaec1e41b1d3396d649c80749c4e Reviewed-on: https://go-review.googlesource.com/28471Reviewed-by:

The block b4 contains only phi-ops, i.e. no actual code besides the jump to b2. However b4 is not trimmed, because it a) has more than one predecessor, and b) it is not empty. This change enhances trim.go to remove more blocks, subject to the following criteria: - block has predecessors (i.e. not the start block) - block is BlockPlain - block does not loop back to itself - block is the single predecessor of its successor; the instructions of the block are merged into the successor - block does no emit actual code, besides a possible unconditional jump. Currently only OpPhi are considered to not be actual code, perhaps OpKeepAlive/others should be considered too? As an example, after the change, the block b4 is trimmed and the jump at 18 jumps directly to 8. Revision 1: Adjust phi-ops arguments after merge Ensure the number of phi-ops arguments matches the new number of predecessors in the merged block. When moving values, make them refer to the merged block. Revision 2: - Make clear the intent that we do not want to trim the entry block - Double check that we are merging a phi operation - Minor code style fix - Fix a potentially dangerous situation when a blocks refers to the inline value space in another block Change-Id: I0ab91779f931f404d11008f5c45606d985d7fbaa Reviewed-on: https://go-review.googlesource.com/28812 Run-TryBot: Russ Cox <rsc@golang.org> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by:Keith Randall <khr@golang.org>
