Removes an intermediate layer of functions that was clogging up a corner of the compiler's profile graph. I can't measure a performance improvement running a large build like jujud, but the profile reports less total time spent in gc.(*lexer).getr.

In addition to reflect.Value.Call, exported methods can be invoked by the Func value in the reflect.Method struct. This CL has the compiler track what functions get access to a legitimate reflect.Method struct by looking for interface calls to either of: Method(int) reflect.Method MethodByName(string) (reflect.Method, bool) This is a little overly conservative. If a user implements a type with one of these methods without using the underlying calls on reflect.Type, the linker will assume the worst and include all exported methods. But it's cheap. No change to any of the binary sizes reported in cl/20483. For #14740 Change-Id: Ie17786395d0453ce0384d8b240ecb043b7726137 Reviewed-on: https://go-review.googlesource.com/20489Reviewed-by:

Part 1 of optimizing the deflater. This optimizes the bitwriter by: * Removing allocations. * Storing compound values for bit codes instead of 2 separate tables. * Accumulate 48 bits between writes instead of 24. * Inline bit flushing. This also contains code that will be used in later CL's (writeBlockDynamic, writeBlockHuff). Tests for Huffman bit writer encoding regressions has been added. name old speed new speed delta EncodeDigitsSpeed1e4-4 19.3MB/s ± 1% 21.6MB/s ± 1% +11.77% EncodeDigitsSpeed1e5-4 25.0MB/s ± 6% 30.7MB/s ± 1% +22.70% EncodeDigitsSpeed1e6-4 28.2MB/s ± 1% 32.3MB/s ± 1% +14.64% EncodeDigitsDefault1e4-4 13.3MB/s ± 0% 14.2MB/s ± 1% +7.07% EncodeDigitsDefault1e5-4 6.43MB/s ± 1% 6.64MB/s ± 1% +3.27% EncodeDigitsDefault1e6-4 5.81MB/s ± 0% 5.85MB/s ± 1% +0.69% EncodeDigitsCompress1e4-4 13.2MB/s ± 0% 14.4MB/s ± 0% +9.10% EncodeDigitsCompress1e5-4 6.40MB/s ± 1% 6.61MB/s ± 0% +3.20% EncodeDigitsCompress1e6-4 5.80MB/s ± 1% 5.90MB/s ± 1% +1.64% EncodeTwainSpeed1e4-4 18.4MB/s ± 1% 20.7MB/s ± 1% +12.72% EncodeTwainSpeed1e5-4 27.7MB/s ± 1% 31.0MB/s ± 1% +11.78% EncodeTwainSpeed1e6-4 29.1MB/s ± 0% 32.9MB/s ± 2% +13.25% EncodeTwainDefault1e4-4 12.4MB/s ± 0% 13.1MB/s ± 1% +5.88% EncodeTwainDefault1e5-4 7.52MB/s ± 1% 7.83MB/s ± 0% +4.19% EncodeTwainDefault1e6-4 7.08MB/s ± 1% 7.26MB/s ± 0% +2.54% EncodeTwainCompress1e4-4 12.0MB/s ± 1% 12.8MB/s ± 1% +6.70% EncodeTwainCompress1e5-4 5.96MB/s ± 1% 6.16MB/s ± 0% +3.27% EncodeTwainCompress1e6-4 5.37MB/s ± 0% 5.39MB/s ± 1% +0.47% >Allocations: benchmark old allocs new allocs delta BenchmarkEncodeDigitsSpeed1e4-4 50 0 -100.00% BenchmarkEncodeDigitsSpeed1e5-4 110 0 -100.00% BenchmarkEncodeDigitsSpeed1e6-4 1032 0 -100.00% BenchmarkEncodeDigitsDefault1e4-4 56 0 -100.00% BenchmarkEncodeDigitsDefault1e5-4 120 0 -100.00% BenchmarkEncodeDigitsDefault1e6-4 966 0 -100.00% BenchmarkEncodeDigitsCompress1e4-4 56 0 -100.00% BenchmarkEncodeDigitsCompress1e5-4 120 0 -100.00% BenchmarkEncodeDigitsCompress1e6-4 966 0 -100.00% BenchmarkEncodeTwainSpeed1e4-4 58 0 -100.00% BenchmarkEncodeTwainSpeed1e5-4 132 0 -100.00% BenchmarkEncodeTwainSpeed1e6-4 1082 0 -100.00% BenchmarkEncodeTwainDefault1e4-4 52 0 -100.00% BenchmarkEncodeTwainDefault1e5-4 126 0 -100.00% BenchmarkEncodeTwainDefault1e6-4 886 0 -100.00% BenchmarkEncodeTwainCompress1e4-4 52 0 -100.00% BenchmarkEncodeTwainCompress1e5-4 120 0 -100.00% BenchmarkEncodeTwainCompress1e6-4 880 0 -100.00% benchmark old bytes new bytes delta BenchmarkEncodeDigitsSpeed1e4-4 4288 2 -99.95% BenchmarkEncodeDigitsSpeed1e5-4 8896 15 -99.83% BenchmarkEncodeDigitsSpeed1e6-4 84098 153 -99.82% BenchmarkEncodeDigitsDefault1e4-4 4480 3 -99.93% BenchmarkEncodeDigitsDefault1e5-4 9216 76 -99.18% BenchmarkEncodeDigitsDefault1e6-4 73920 768 -98.96% BenchmarkEncodeDigitsCompress1e4-4 4480 3 -99.93% BenchmarkEncodeDigitsCompress1e5-4 9216 76 -99.18% BenchmarkEncodeDigitsCompress1e6-4 73920 768 -98.96% BenchmarkEncodeTwainSpeed1e4-4 4544 2 -99.96% BenchmarkEncodeTwainSpeed1e5-4 9600 15 -99.84% BenchmarkEncodeTwainSpeed1e6-4 77633 153 -99.80% BenchmarkEncodeTwainDefault1e4-4 4352 3 -99.93% BenchmarkEncodeTwainDefault1e5-4 9408 76 -99.19% BenchmarkEncodeTwainDefault1e6-4 65984 768 -98.84% BenchmarkEncodeTwainCompress1e4-4 4352 3 -99.93% BenchmarkEncodeTwainCompress1e5-4 9216 76 -99.18% BenchmarkEncodeTwainCompress1e6-4 65792 768 -98.83% Updates #14258 Change-Id: Ibaa97b9619743ad623094727228eb2ada1ec7f1f Reviewed-on: https://go-review.googlesource.com/19336Reviewed-by:

This will test if deflate output is deterministic between two runs of the deflater, when write sizes differ. The deflater makes no official promises that results are deterministic between runs, but this is a good test to determine unintentional randomness. Note that this does not guarantee that results are deterministic across platforms nor that results will be deterministic between Go versions. This is also not guarantees we should imply.

The location of VARDEFs is incorrect for PPARAMOUT variables which are also used as temporary locations. We put in VARDEFs when setting the variable at return time, but when the location is also used as a temporary the lifetime values are wrong. Fix copyelim to update the names map properly. This is a real name bug fix which, as a result, allows me to write a reasonable test to trigger the PPARAMOUT bug. This is kind of a band-aid fix for #14591. A more pricipled fix (which allows values to be stored in the return variable earlier than the return point) will be harder.

PKIX versions are off-by-one, so v1 is actually a zero on the wire, v2 is a one, and so on. The RFC says that the version in a CRL is optional, but doesn't say what the default is. Since v2 is the only accepted version, I had made the default v2. However, OpenSSL considers the default to be v1. Also, if the default is v2 and the element is optional then we'll never actually write v2 on the wire. That's contrary to the RFC which clearly assumes that v2 will be expressed on the wire in some cases. Therefore, this change aligns with OpenSSL and assumes that v1 is the default CRL version.

I would like to add a func (t *Type) Elem() *Type method to package gc, but that would collide with the existing func (t *Type) Elem() ssa.Type method needed to make *gc.Type implement ssa.Type. Because the latter is much less widely used right now than the former will be, this CL renames it to ElemType. Longer term, hopefully gc and ssa will share a common Type interface, and ElemType can go away.

Make sure we do any just-before-return cleanup on all paths out of a function, including when recovering. Each exit path should include deferreturn (if there are any defers) and then the exit code (e.g. copying heap-escaping return values back to the stack). Introduce a Defer SSA block type which has two outgoing edges - one the fallthrough edge (the defer was queued successfully) and one which immediately returns (the defer had a successful recover() call and normal execution should resume at the return point).
