2010-05-03big: completed set of Int division routines & cleanupsRobert Griesemer1-2/+2
- renamed Len -> BitLen, simplified implementation - renamed old Div, Mod, DivMod -> Que, Rem, QuoRem - implemented Div, Mod, DivMod (Euclidian definition, more useful in a mathematical context) - fixed a bug in Exp (-0 was possible) - added extra tests to check normalized results everywhere - uniformly set Int.neg flag at the end of computations - minor cosmetic cleanups - ran all tests R=rsc CC=golang-dev http://codereview.appspot.com/1091041

2010-04-30big: use fast shift routinesRobert Griesemer1-2/+2
- fixed a couple of bugs in the process (shift right was incorrect for negative numbers) - added more tests and made some tests more robust - changed pidigits back to using shifts to multiply by 2 instead of add This improves pidigit -s -n 10000 by approx. 5%: user 0m6.496s (old) user 0m6.156s (new) R=rsc CC=golang-dev http://codereview.appspot.com/963044

2009-12-151) Change default gofmt default settings forRobert Griesemer15-558/+558
parsing and printing to new syntax. Use -oldparser to parse the old syntax, use -oldprinter to print the old syntax. 2) Change default gofmt formatting settings to use tabs for indentation only and to use spaces for alignment. This will make the code alignment insensitive to an editor's tabwidth. Use -spaces=false to use tabs for alignment. 3) Manually changed src/exp/parser/parser_test.go so that it doesn't try to parse the parser's source files using the old syntax (they have new syntax now). 4) gofmt -w src misc test/bench 5th and last set of files.

2009-12-11Remove GOBIN in PATH dependency; don't assume cwd is $GOROOT/srcDevon H. O'Dell1-2/+5
This change removes the necessity to have GOBIN in $PATH, and also doesn't assume that the build is being run from $GOROOT/src. This is a minimal set of necessary changes to get Go to build happily from the FreeBSD ports collection. R=rsc CC=golang-dev http://codereview.appspot.com/171044 Committer: Russ Cox <rsc@golang.org>

2009-11-23go: makes it build for the case $GOROOT has whitespacesSergio Luis O. B. Correia1-1/+1
the bash scripts and makefiles for building go didn't take into account the fact $GOROOT / $GOBIN could both be directories containing whitespaces, and was not possible to build it in such a situation. this commit adjusts the various makefiles/scripts to make it aware of that possibility, and now it builds successfully when using a path with whitespaces as well.
