to be consistent with the fdct function, and to ease any future idct rewrites in assembly. The BenchmarkIDCT delta is obviously just an accounting change and not a real saving, but it does give an indication of what proportion of time was spent in the actual IDCT and what proportion was in shift and clip. The idct time taken is now comparable to fdct. The BenchmarkFDCT delta is an estimate of benchmark noise. benchmark old ns/op new ns/op delta BenchmarkFDCT 3842 3837 -0.13% BenchmarkIDCT 5611 3478 -38.01% BenchmarkDecodeRGBOpaque 2932785 2929751 -0.10% R=r CC=golang-dev https://golang.org/cl/6625057

rundir will compile each file in the directory in lexicographic order, link the last file as the main package and run the resulting program. rundircmpout is an related command, that will compare the output of the program to an corresponding .out file errorcheckdir will compile each file in a directory in lexicographic order, running errorcheck on each file as it compiles. All compilations are assumed to be successful except for the last file. However, If a -0 flag is present on the command, the last compilation will also be assumed successful This CL also includes a small refactoring of run.go. It was getting unwieldy and the meaning of the run commands was hidden behind argument line formatting. Fixes #4058. R=rsc, minux.ma, remyoudompheng, iant CC=golang-dev https://golang.org/cl/6554071

The Go run-time assumes that all SSE floating-point exceptions are masked so that Go programs are not broken by such invalid operations. By default, the 64-bit version of the Plan 9 kernel masks only some SSE floating-point exceptions. Here, we mask them all on a per-thread basis.

The AST representation is already identical. Making the code (nearly) identical in the parser reduces code size and ensures that the ast.ValueSpec nodes have the same values (specifically, iota). This in turn permits the sharing of much of the respective code in the typechecker. While at it: type functions work now, so use them. R=r CC=golang-dev https://golang.org/cl/6624047

Also: Be explicit what operator means with respect to conversion types. The parenthesis requirement is a language change. At the moment, literal function types in conversions that cannot possibly be followed by a '(' don't need parentheses. For instance: func(int)int(x) -> same as (func(int)int)(x) func()()(x) -> same as (func())(x) but: func(int)(x) -> could be func(int)x {...} Fixes #4109.

They now show the correct name, the byte offset on the line, and context for the failed evaluation. Before: template: three:7: error calling index: index out of range: 5 After: template: top:7:20: executing "three" at <index "hi" $>: error calling index: index out of range: 5 Here top is the template that was parsed to create the set, and the error appears with the action starting at byte 20 of line 7 of "top", inside the template called "three", evaluating the expression <index "hi" $>. Also fix a bug in index: it didn't work on strings. Ouch. Also fix bug in error for index: was showing type of index not slice. The real previous error was: template: three:7: error calling index: can't index item of type int The html/template package's errors can be improved by building on this; I'll do that in a separate pass. Extends the API for text/template/parse but only by addition of a field and method. The old API still works. Fixes #3188. R=golang-dev, dsymonds CC=golang-dev https://golang.org/cl/6576058
