2010-06-29code gen bug in len(nil) and cap(nil)Ken Thompson1-0/+4
fixes issue 892 R=rsc CC=golang-dev http://codereview.appspot.com/1745042
2010-05-20fix issue 798Ken Thompson1-0/+6
cannot allocate an audomatic temp while real registers are allocated. there is a chance that the automatic will be allocated to one of the allocated registers. the fix is to not registerize such variables. R=rsc CC=golang-dev http://codereview.appspot.com/1202042

2010-02-01gc: add ... T, rework plain ...Russ Cox1-1/+0
No longer a distinct type; now a property of func types. R=ken2 CC=golang-dev http://codereview.appspot.com/197042
2010-01-22eliminate the package global name space assumption in object filesRuss Cox1-2/+2
5g/6g/8g: add import statements to export metadata, mapping package path to package name. recognize "" as the path of the package in export metadata. use "" as the path of the package in object symbol names. 5c/6c/8c, 5a/6a/8a: rewrite leading . to "". so that ·Sin means Sin in this package. 5l/6l/8l: rewrite "" in symbol names as object files are read. gotest: handle new symbol names. gopack: handle new import lines in export metadata. Collectively, these changes eliminate the assumption of a global name space in the object file formats. Higher level pieces such as reflect and the computation of type hashes still depend on the assumption; we're not done yet.
