Subject: perf dwarf-regs: Add util/dwarf-regs-arch for consistency with perf-regs
X-Git-Tag: v7.0-rc1~16^2~183
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1672f3707a6ef4b386c30bb76df2f62e58a39430;p=thirdparty%2Flinux.git

perf dwarf-regs: Add util/dwarf-regs-arch for consistency with perf-regs

perf_regs.h has cross architecture functions for operating with the
differing perf register constants. dwarf-regs.h is similar but for
cross architecture dwarf notions of registers.

For consistency move the arch parts of dwarf-regs out of util and into
its own directory.
