perf annotate: Make output more readable
This patch adds two new options to perf annotate: - --no-asm-raw : Do not display raw instruction encodings - --no-source : Do not interleave source code with assembly code We believe those options make the output of annotate more readable. Systematically displaying source can make it hard to follow code and especially optimized code. Raw encodings are not useful in most cases.
