Subject: sim: add helper macros for branch profiling
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=58f03a4028987eef6b222b41d49e1f5781510b7c;p=binutils-gdb.git

sim: add helper macros for branch profiling

The profile code has a lot of helper macros already, but none yet for the
branch profiling code.  So add ones for the basic functions -- taken and
untaken branches.
