From: Richard Allen Date: Sun, 9 Feb 2025 16:49:01 +0000 (-0600) Subject: gprof: fix odd inst len hist scale calculation X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=2effb0d11fd184e432dbce2cd6e45240471c1189;p=thirdparty%2Fbinutils-gdb.git gprof: fix odd inst len hist scale calculation With even instruction sizes, this rounding never truncated. Xtensa CPUs mostly use 2-3 byte instructions, and this can lead to a histogram being captured with an odd length address range. This small truncation prevented gprof from parsing gmon.out files containing multiple histograms when at least one of them has an odd address range length and another has any other address range.
