In cl/8652 I broke darwin/arm and darwin/386 because I removed the *g parameter, which they both expect and use. This CL adjusts both ports to look for g0 in m, just as darwin/amd64 does. Tested on darwin{386,arm,amd64}. Change-Id: Ia56f3d97e126b40d8bbd2e8f677b008e4a1badad Reviewed-on: https://go-review.googlesource.com/8666Reviewed-by:Ian Lance Taylor <iant@golang.org>

This is a practice run for darwin/arm. Similar to the linux/amd64 shared library entry point. With several pending linker changes I am successfully using this to implement -buildmode=c-archive on darwin/amd64 with external linking. The same entry point can be reused to implement -buildmode=c-shared on darwin/amd64, however that will require further ld changes to remove all text relocations. One extra runtime change will follow this. According to the Go execution modes document, -buildmode=c-archive should ignore the Go main function. Right now it is being executed (and the process exits if it doesn't block). I'm still searching for the right way to do this.

The linker currently (on some platforms) takes a -shared flag, which means approximately what -buildmode=c-shared means in the in the proposed "Go Execution Modes" document. As part of implementing other modes, the term "shared" becomes horribly overloaded, so this replaces -shared with a -buildmode argument instead (which currently only handles -buildmode=c-shared and the default -buildmode=exe -- no new behaviour here). As the linker support for -shared was in 1.4 this retains it as an alias. Change-Id: Id2ebb8e05ee07f46208a554bc2622d0e67b47082 Reviewed-on: https://go-review.googlesource.com/8304Reviewed-by:

This CL is quite conservative in some ways. It continues to define symbols that have no real purpose (e.g. epclntab). These could be deleted if there is no concern that external tools might look for them. It would also now be possible to make some changes to the pcln data but I get the impression that would definitely require some thought and discussion.

Previously if the connection pool was larger than maxBadConnRetries and there were a lot of bad connections in the pool (for example if the database server was restarted), a query might have failed with an ErrBadConn unnecessarily. Instead of trying to guess how many times to retry, try maxBadConnRetries times and then force a fresh connection to be used for the last attempt. At the same time, lower maxBadConnRetries to a smaller value now that it's not that important to retry so many times from the free connection list.

Change function appendUint to appendInt with variable-width 0-padding. This allows the decimal for the year to be generated without extra code to handle the wider padding and directly handles negative numbers. Removes the special casing for numbers with one and two digits. The special case for 0 was unreachable.

Update #10203 When the portable componentgen was introduced in b9602632 it produced broken code on arm64 and was deactivated. In the month since it looks like the underlying issues have been fixed so componentgen produces working binaries that are slightly smaller, ~3kb reduction in size for godoc binary. Benchmarks are underwhelming, but where visible, trending towards an improvement (this is with Minux's peep optimiser CL). benchmark old ns/op new ns/op delta BenchmarkBinaryTree17 15336842000 15002766000 -2.18% BenchmarkFannkuch11 10848984000 10896931000 +0.44% BenchmarkFmtFprintfEmpty 203 188 -7.39% BenchmarkFmtFprintfString 753 720 -4.38% BenchmarkFmtFprintfInt 667 670 +0.45% BenchmarkFmtFprintfIntInt 1103 1102 -0.09% BenchmarkFmtFprintfPrefixedInt 981 969 -1.22% BenchmarkFmtFprintfFloat 1396 1348 -3.44% BenchmarkFmtManyArgs 4151 4102 -1.18% BenchmarkGobDecode 34202360 32933020 -3.71% BenchmarkGobEncode 27579180 27438820 -0.51% BenchmarkGzip 1296119000 1285096000 -0.85% BenchmarkGunzip 291099800 289727200 -0.47% BenchmarkHTTPClientServer 169476 169803 +0.19% BenchmarkJSONEncode 70313600 69973400 -0.48% BenchmarkJSONDecode 227811800 232875200 +2.22% BenchmarkMandelbrot200 12985600 12996430 +0.08% BenchmarkGoParse 14708930 14507320 -1.37% BenchmarkRegexpMatchEasy0_32 464 460 -0.86% BenchmarkRegexpMatchEasy0_1K 4516 4517 +0.02% BenchmarkRegexpMatchEasy1_32 452 454 +0.44% BenchmarkRegexpMatchEasy1_1K 4664 4669 +0.11% BenchmarkRegexpMatchMedium_32 602 602 +0.00% BenchmarkRegexpMatchMedium_1K 172939 172494 -0.26% BenchmarkRegexpMatchHard_32 9733 9577 -1.60% BenchmarkRegexpMatchHard_1K 301356 298143 -1.07% BenchmarkRevcomp 2754334000 2753874000 -0.02% BenchmarkTemplate 315664000 311810800 -1.22% BenchmarkTimeParse 1034 989 -4.35% BenchmarkTimeFormat 1118 1137 +1.70% benchmark old MB/s new MB/s speedup BenchmarkGobDecode 22.44 23.31 1.04x BenchmarkGobEncode 27.83 27.97 1.01x BenchmarkGzip 14.97 15.10 1.01x BenchmarkGunzip 66.66 66.98 1.00x BenchmarkJSONEncode 27.60 27.73 1.00x BenchmarkJSONDecode 8.52 8.33 0.98x BenchmarkGoParse 3.94 3.99 1.01x BenchmarkRegexpMatchEasy0_32 68.92 69.47 1.01x BenchmarkRegexpMatchEasy0_1K 226.71 226.65 1.00x BenchmarkRegexpMatchEasy1_32 70.75 70.42 1.00x BenchmarkRegexpMatchEasy1_1K 219.55 219.28 1.00x BenchmarkRegexpMatchMedium_32 1.66 1.66 1.00x BenchmarkRegexpMatchMedium_1K 5.92 5.94 1.00x BenchmarkRegexpMatchHard_32 3.29 3.34 1.02x BenchmarkRegexpMatchHard_1K 3.40 3.43 1.01x BenchmarkRevcomp 92.28 92.29 1.00x BenchmarkTemplate 6.15 6.22 1.01x Change-Id: I0b7d95388d6920fcbd7fe305df0c7c630a407726 Reviewed-on: https://go-review.googlesource.com/8636Reviewed-by:
