2014-10-29cmd/objdump: disable test failing on arm5go1.4beta1Russ Cox

2014-10-29cmd/objdump: use cmd/internal/objfileRuss Cox
This removes a bunch of ugly duplicate code. The end goal is to factor the disassembly code into cmd/internal/objfile too, so that pprof can use it, but one step at a time. LGTM=r, iant R=r, alex.brainman, iant CC=golang-codereviews https://golang.org/cl/149400043

2014-09-30cmd/objdump: move armasm, x86asm into internal packagesRuss Cox
For Go 1.3 these external packages were collapsed into large single-file implementations stored in the cmd/objdump directory. For Go 1.4 we want pprof to be able to link against them too, so move them into cmd/internal, where they can be shared. The new files are copied from the repo in the file path (rsc.io/...). Those repos were code reviewed during development (mainly by crawshaw and minux), because we knew the main repo would use them.

2014-07-19cmd/addr2line, cmd/objdump: fix on amd64 Plan 9David du Colombier
Fix virtual address of the start of the text segment on amd64 Plan 9. This issue has been partially fixed in cmd/add2line, as part of CL 106460044, but we forgot to report the change to cmd/objdump. In the meantime, we also fixed the textStart address in both cmd/add2line and cmd/objdump.

2014-05-21cmd/objdump: fix dissasembly of Plan 9 object filesAnthony Martin
Ignore symbols that aren't text, data, or bss since they cause problems when dissassembling instructions with small immediate values. Before: build.go:142 0x10ee 83ec50 SUBL $text/template/parse.autotmp_1293(SB), SP After: build.go:142 0x10ee 83ec50 SUBL $0x50, SP Fixes #7947.

2014-05-20build: make nacl passRuss Cox
Add nacl.bash, the NaCl version of all.bash. It's a separate script because it builds a variant of package syscall with a large zip file embedded in it, containing all the input files needed for tests. Disable various tests new since the last round, mostly the ones using os/exec. Fixes #7945.

2014-05-14cmd/nm, cmd/objdump: fix elf symbol typesRuss Cox
Turns out elf.File.Sections is indexed by the actual section number, not the number minus one. I don't know why I thought the -1 was necessary. Fixes objdump test (and therefore build) on ELF systems. While we're here, fix bounds on gnuDump so that we don't crash when asked to disassemble outside the text segment. May fix Windows build or at least make the failure more interesting. TBR=iant CC=golang-codereviews https://golang.org/cl/92390043
2014-05-14objdump: implement disassemblyRuss Cox
There is some duplication here with cmd/nm. There is a TODO to address that after 1.3 is out. Update #7452 x86 disassembly works and is tested. The arm disassembler does not exist yet and is therefore not yet hooked up. LGTM=crawshaw, iant R=crawshaw, iant CC=golang-codereviews https://golang.org/cl/91360046
2014-05-14cmd/objdump: import x86 disassemblerRuss Cox
The x86 disassembler lives in rsc.io/x86/x86asm for now. We need to figure out what should live where in the long term, but not before the 1.3 release. The completed code reviews for the disassembler are at: https://golang.org/cl/95350044 https://golang.org/cl/95300044 https://golang.org/cl/97100047 https://golang.org/cl/93110044 https://golang.org/cl/99000043 https://golang.org/cl/98990043 LGTM=crawshaw R=crawshaw, jacek.masiulaniec CC=golang-codereviews https://golang.org/cl/92360043

2014-04-14cmd/objdump: rewrite in GoRuss Cox
Update cmd/dist not to build the C version. Update cmd/go to install the Go version to the tool directory. Update #7452 This is the basic logic needed for objdump, and it works well enough to support the pprof list and weblist commands. A real disassembler needs to be added in order to support the pprof disasm command and the per-line assembly displays in weblist. That's still to come. Probably objdump will move to go.tools when the disassembler is added, but it can stay here for now.

2012-02-28runtime/pprof: support OS X CPU profilingRuss Cox
Work around profiling kernel bug with signal masks. Still broken on 64-bit Snow Leopard kernel, but I think we can ignore that one and let people upgrade to Lion. Add new trivial tools addr2line and objdump to take the place of the GNU tools of the same name, since those are not installed on OS X. Adapt pprof to invoke 'go tool addr2line' and 'go tool objdump' if the system tools do not exist. Clean up disassembly of base register on amd64. Fixes #2008.
