Subject: perf dump-insn: Remove dump-insn.c
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=8e6f3103c079d44b51177449cd93af4c18733194;p=thirdparty%2Fkernel%2Flinux.git

perf dump-insn: Remove dump-insn.c

dump_insn and arch_is_uncond_branch are declared in
intel-pt-insn-decoder.c which is unconditionally part of all perf
builds. Don't declare weak versions of these symbols that will be unused.
