Subject: gprof: speed up line-by-line for MIPS/PowerPC/RISCV/SuperH
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=b6539282a9378cc2587b480c3fc5c75adabf6301;p=thirdparty%2Fbinutils-gdb.git

gprof: speed up line-by-line for MIPS/PowerPC/RISCV/SuperH

Roughly halves the number of bfd_find_nearest_line() calls,
about 40% less time for a few different large ELF files.
