2010-06-30cgo: use slash-free relative paths for .so referencesRuss Cox1-0/+2
The Makefile and cgo now rewrite / to _ when creating the path. The .so for gosqlite.googlecode.com/hg/sqlite is named cgo_gosqlite.googlecode.com_hg_sqlite.so, and then 6l and 8l both include a default rpath of $GOROOT/pkg/$GOOS_$GOARCH. This should make it easier to move binaries from one system to another. Fixes issue 857. R=iant, r CC=golang-dev http://codereview.appspot.com/1700048

2010-02-26Add -r option to 6l/8l/5l.Ian Lance Taylor1-1/+4
This permits more flexibility with cgo and swig in cases where the program is run on a machine other than the one on which it is built. Rather than storing the absolute path to the shared library in the DT_NEEDED entry, we can store just the name, and let the dynamic linker find it using DT_RUNPATH or the LD_LIBRARY_PATH environment variable.

2010-01-25ld: do not load the same object file multiple times.Russ Cox1-0/+6
eliminates spurious multiple initialization errors. give more information in the multiple init errors that remain. Fixes issue 87. R=r CC=golang-dev http://codereview.appspot.com/194052
2010-01-22eliminate the package global name space assumption in object filesRuss Cox1-4/+8
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.

2010-01-19cleanup toward eliminating package global name spaceRuss Cox1-1/+1
* switch to real dot (.) instead of center dot (·) everywhere in object files. before it was half and half depending on where in the name it appeared. * in 6c/6a/etc identifiers, · can still be used but turns into . immediately. * in export metadata, replace package identifiers with quoted strings (still package names, not paths).

- morestack support for 5l and arm runtime - argsize support in 5c, 5l, ar and nm. assembly code from 5a will break in interesting ways unless NOSPLIT is specified - explicit cond execution constants - fix 5l output to use %d instead of %ld so that negative values show. - added a lot of code to arm/asm.s. runtime entry code almost working currently aborts at gogo not implemented R=rsc APPROVED=rsc DELTA=305 (125 added, 29 deleted, 151 changed) OCL=30246 CL=30347

2009-03-25This is really two changes in one but given interdependenciesKai Backman1-13/+13
and expected review latency I needed to combine the CLs. 1. Made the 5* toolpath build using the go build system. Hooked the subdirectories to clean.bash but added a separate make5.bash for now. Minor massage to make the code more similar to the current structure of 6c/6a/6l. 2. Change all references from long to int32 in line with similar change for the other toolchains. The end result is that 5c, 5a and 5l can now be compiled and the executables start up properly. Haven't thrown any input at them yet.
