Subject: gprof: rename min_insn_size to insn_boundary
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f19534f257eb2643624414c22aa5a32da39d7b66;p=thirdparty%2Fbinutils-gdb.git

gprof: rename min_insn_size to insn_boundary

This distinction is important for architecures like Xtensa,
where 2B and 3B instructions are common, but the correct
value for instruction iteration is 1B, not 2B.
