2009-11-19add a match arena to regexp to avoid generating garbage.Rob Pike1-46/+106
simple regexps run 20x faster. the regex-dna benchmark goes 3x faster. R=rsc CC=golang-dev http://codereview.appspot.com/156108
2009-11-19two easy optimizations for regexp:Rob Pike1-13/+78
1) if char class contains a single character, make it a single character. (this is used to quote, e.g. [.] rather than \. 2) if regexp begins with ordinary text substring, use plain string match to start engine R=rsc CC=golang-dev http://codereview.appspot.com/157095
2009-11-18remove bytes.CopyRob Pike1-15/+7
replace all calls with calls to copy use copy in regexp and bytes.Buffer R=rsc CC=golang-dev http://codereview.appspot.com/157073
2009-11-14move evaluation of null-matching instructions one iteration earlier.Rob Pike1-31/+47
performance hit of about 20% but more intuitive results for submatches. we need a good regexp package at some point. Fixes issue 110. R=rsc CC=golang-dev http://codereview.appspot.com/152131
2009-11-09- replaced gofmt expression formatting algorithm withRobert Griesemer1-22/+22
rsc's algorithm - applied gofmt -w misc src - partial CL (last chunk) R=rsc, r http://go/go-review/1024041
2009-11-09remove semis after statements in one-statement statement listsRobert Griesemer1-71/+71
R=rsc, r http://go/go-review/1025029
2009-11-06- fine-tuning of one-line func heuristic (nodes.go)Robert Griesemer1-93/+31
- enabled for function declarations (not just function literals) - applied gofmt -w $GOROOT/src (look for instance at src/pkg/debug/elf/elf.go) R=r, rsc CC=go-dev http://go/go-review/1026006
2009-11-05gofmt'ed missing regexp fileRobert Griesemer1-137/+187
(one-line functions will be re-established once we have all formatted uniformly) R=r http://go/go-review/1023004

2009-08-26generate the unicode tables directly from web databaseRob Pike1-1/+1
