GODEBUG=gctrace=1 turns on a per-GC cycle trace line. The current line is left over from the STW garbage collector and includes a lot of information that is no longer meaningful for the concurrent GC and doesn't include a lot of information that is important. Replace this line with a new line designed for the new garbage collector. This new line is focused more on helping the user understand the impact of the garbage collector on their program and less on telling us, the runtime developers, everything that's happening inside GC. It's designed to fit in 80 columns and intentionally omit some potentially useful things that were in the old line. We might want a "verbose" mode that adds information for us. We'll be able to further simplify the line once we eliminate the STW around enabling the write barrier. Then we'll have just one STW phase, one concurrent phase, and one more STW phase, so we'll be able to reduce the number of times from five to three.

This restores go.errors from before 3af0d791 along with a fixed up version of the bisonerrors AWK script, translated to Go.

Yacc generates a bunch of global variables of the form var yyFoo = []int{...} where yyFoo is never subsequently modified to point to a different slice. Since these variables are implicitly compiled as var yyFoo = ([...]int{...})[:] anyway, by simply converting them all to var yyFoo = [...]int{...} we save sizeof(sliceStruct) bytes of data memory for each variable and also make len(yyFoo) into compile-time constant expressions, which shaves some bytes off text size: $ size 6g.before 6g.after text data bss dec hex filename 4598019 605968 342700 5546687 54a2bf 6g.before 4597810 605552 342700 5546062 54a04e 6g.after Change-Id: I53c7aa6efdb2d52738013e9d337a59afbfcb2494 Reviewed-on: https://go-review.googlesource.com/7520 Run-TryBot: Matthew Dempsky <mdempsky@google.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by:Dave Cheney <dave@cheney.net> Reviewed-by:

On arm64, CMP $foo, R is encoded as from=$foo, reg=R, not as from=$foo, to=R. The progtable entry for ACMP incorrectly described the latter form. Because of this, the registerizer was not accounting the registers used in CMP instructions and was incorrectly re-assigning those registers. This was an old problem, but it only became apparent after b115c35e (cmd/internal/gc: move cgen, regalloc, et al to portable code). Previous to this commit, the compiler used a slightly larger register set for the temps than it used for register variables. Since it had plenty registers dedicated to temps, the registers used in CMP instruction never clashed with registers assigned to register variables.

Nodes dominate gc's memory usage, but many fields are only used for a subset of kinds of nodes. This change pulls out fields used only for func-like Nodes. This reduces the size of the Node struct on a 64-bit machine from 504 bytes to 416 bytes (-17%). Compiling the runtime, 1.5% of nodes have a non-nil Func. In html/template, 2.7% of nodes have a non-nil Func. This change introduces an extra alloc and associated GC overhead when Func is non-nil. However, when Func is nil, as it almost always is, it spares the garbage collector scanning some Node fields. Empirically, this change appears to be roughly neutral with regard to GC. To keep the diff readable, this CL uses an embedded Func field. A subsequent CL will unembed the field. Passes toolstash -cmp.

This change stabilizes the result of Sort when the error list contains multiple items for same position. To stabilize the result, newly also the Msg field is considered. The motivation is to avoid diffs of sorted scanner.ErrorList output in repository tracked logs like: -testdata/foo.go:19:44: "bar" testdata/foo.go:19:44: "qux" +testdata/foo.go:19:44: "bar" The change was approved at [0] before submitting. As a side effect, one file in go/parser/testdata must be updated as well. For this file the parser produces two different errors: testdata/issue3106.src:22:5: expected ';', found 'if' testdata/issue3106.src:22:5: expected operand, found 'if' Before comparing the actual and expected errors, the former are filtered to keep only one error per source line[1]. With the new (*ErrorList).Less the outcome is the other error than before which is kept after the call to RemoveMultiplies.

Additionally this CL brings gccgoToolchain.ldi() up to date with the version that will ship in gccgo-5.0. As gccgo is most likely to be used with its own version of the go tool that it supples it makes good sense that the libgo version should dictate the contents of gccgotoolchain.ld() Please see https://codereview.appspot.com/222890043/ for more details on the issues fixed.

Currently, scanner uses -1 to represent 2 different states: 1. I haven't yet scanned anything, call it "Beginning of File" 2. I've reached the end of the input, ie EOF The result of this behavior is that calling Peek() when next() has detected the end of the input and set s.ch to scanner.EOF, is that Peek() things "oh, s.ch is < 0, which to me means that I haven't scanned any next yet, let me try and clear the BOM marker." When this behavior is run on a typical IO, next() will issue a Read and get (0, io.EOF) back for the second time without blocking and Peek() will return scanner.EOF. The bug comes into play when, inside a terminal, hitting Control-D. This causes the terminal to return a EOF condition to the reader but it does not actually close the fd. So, combining these 2 situations, we arrive at the bug: What is expected: hitting Control-D in a terminal will make Peek() return scanner.EOF instantly. What actually happens: 0. Code waiting in Next() 1. User hits Control-D 2. fd returns EOF condition 3. EOF bubbles it's way out to line 249 in scanner.go 4. next() returns scanner.EOF 5. Next() saves the scanner.EOF to s.ch and returns the previous value 6. Peek() runs, sees s.ch < 0, mistakenly thinks it hasn't run yet and tries to read the BOM marker. 7. next() sees the buffer is empty and tries to fill it again, blocking on line 249. The fix is simple: use a different code to indicate that no data has been scanned.

NaNs make the API more complicated for no real good reasons. There are few operations that produce NaNs with IEEE arithmetic, there's no need to copy the behavior.
