2010-01-22eliminate the package global name space assumption in object filesRuss Cox1-38/+51
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 Cox1-14/+14
* 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).

2009-08-24first attempt at real FFI support.Russ Cox1-4/+2
in a .6 file, an export line //ffi T localfib remotefib remote.so means the dynamic linker should initialize localfib, always a pointer, to the address of remotefib, either text (T) or data (D) after loading remote.so. the C compiler will generate an export section when given the pragmas #pragma package fib #pragma ffi T localfib remotefib remote.so needing #pragma package is a bit of a kludge and hopefully could go away later. this is just the 6 tool chain support. other architectures will happen once 6 settles down. code using this to do FFI is in a later CL.

2009-05-056l: eliminate dead code, not just the symbolsRuss Cox1-1/+21
editing the firstp list was ineffective, because follow rebuilds it from the textp list. the symbols for dead code were being dropped from the binary but the code was all still there. text for fmt.Printf("hello, world\n") drops from 143945 to 128650.

2009-03-31* move go-specific loader codeRuss Cox1-0/+587
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.
