Summary: Add a --show-percs option to cg_annotate and
callgrind_annotate.
Product: valgrind
Version: unspecified

OS: Linux
Status: REPORTED

patch
Add a --show-percs option to cg_annotate and callgrind_annotate.
Because it's very useful. As part of this, the "percentage of events
annotated" numbers at the bottom of the output is changed to "events
annotated" so that --show-percs doesn't compute a percentage of a
percentage.
Example output lines:
> 4,967,137,442 (100.0%) PROGRAM TOTALS
>
> 4,543 (25.23%) 17,566 ( 0.43%) 47,993 ( 0.92%)
> /build/glibc-OTsEL5/glibc-2.27/elf/dl-lookup.c
>
> 1 ( 0.01%) 2,000,001 (49.29%) 3,000,004 (57.36%) for (int i = 0; i <
> 1000000; i++) {
The commit also adds some much-needed tests for cg_annotate and
callgrind_annotate.
