2017-10-05compiler: centralize all symbol name handlingIan Lance Taylor10-806/+1145
Consolidate all symbol name handling into the new file names.cc. This is intended to define all the names that will appear in the generated assembly code. Names that will not appear in the assembly code, such as local variable names or label names, remain where they are. This consolidation is not intended to change any of the existing symbol names. Tested by building without and without this patch and comparing the libgo symbol table. Reviewed-on: https://go-review.googlesource.com/68310 * Make-lang.in (GO_OBJS): Add go/names.o.
