* cmd/objdump: implement objdump of .o filesKeith Randall2016-08-241-3/+21
| | | | | | | | | | | | | | | | | | | Update goobj reader so it can provide all the information necessary to disassemble .o (and .a) files. Grab architecture of .o files from header. .o files have relocations in them. This CL also contains a simple mechanism to disassemble relocations and add relocation info as an extra column in the output.

* all: make copyright headers consistent with one space after periodBrad Fitzpatrick2016-03-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | This is a subset of https://golang.org/cl/20022 with only the copyright header lines, so the next CL will be smaller and more reviewable. Go policy has been single space after periods in comments for some time. The copyright header template at: https://golang.org/doc/contribute.html#copyright also uses a single space. Make them all consistent.
