2010-06-11Pad Go symbol table out to page boundary when linking dynamically.Ian Lance Taylor1-3/+3
This avoids a crash when using cgo where glibc's malloc thinks that it can use some of the memory following the symbol table. This fails because the symbol table is mapped read-only, which affects the whole page. R=rsc CC=golang-dev http://codereview.appspot.com/1616042

2010-04-206l, 8l: include ELF header in PT_LOAD mapping for text segmentRuss Cox1-5/+5
Due to page boundary rounding, the header would have been loaded as part of the text segment already, but this change placates the "paxctl" tool on so-called hardened Linux distributions (as if normal distributions weren't already hard enough to use).

2010-02-26Add -r option to 6l/8l/5l.Ian Lance Taylor1-0/+2
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.

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.

2009-09-188l: step toward native client.Russ Cox1-11/+54
- ELF header bits and addresses - do not let instructions span 32-byte boundary - align CALLs so return is to 32-byte boundary - align indirect jump targets to 32-byte boundary (only possible indirect jumps are function entries) still to do: - replace indirect jump, indirect call, and ret with nacl-approved instruction sequences - switch to GS segment for m-local storage R=ken OCL=34818 CL=34818
