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/+3
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

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.

better mach binaries. cgo working on darwin+linux amd64+386. eliminated context switches - pi is 30x faster. add libcgo to build. on snow leopard: - non-cgo binaries work; all tests pass. - cgo binaries work on amd64 but not 386.

* use new Make.$GOARCH files in gobuild. * rename 6ar to arch-generic gopack. * place objects in $GOROOT/pkg/$GOOS_$GOARCH (makes cross-compiling easier, and no one ever types these paths by hand anyway). R=r DELTA=29 (6 added, 8 deleted, 15 changed) OCL=29923 CL=29967

2009-03-31* move go-specific loader codeRuss Cox1-14/+20
into gc directory, where it gets included as ../gc/ldbody this is similar to the assemblers including ../cc/lexbody and ../cc/macbody. * hook go-specific loader code into 8l. * make current 8.out.h and 6.out.h backward compatible with plan 9's versions. i had added some constants in the middle of enums and have now moved them to the end. this keeps us from invalidating old .8 and .6 files. not sure how much it really matters, but easy to do.
