* pmcannotate: Add a '-m' mode option to control per-line annotations.John Baldwin2025-01-141-8/+46
| | | | | | | | | | | | | - "block" (the default mode) displays per-block percentages in front of each annotated line. - "global" displays a global percentage in front of each line. - "raw" displays the raw count of sample hits in front of each line.

| | | | | | | | | The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch up to that fact and revert to their recommended match of BSD-2-Clause. Discussed with: pfg MFC After: 3 days Sponsored by: Netflix
* pmcannotate: Don't increment end address passed to objdump -d.John Baldwin2022-06-141-5/+0
| | | | | | | | | | | | | | | | | | | | | libpmc already returns an end address that is after the end of the last instruction of a function (on both amd64 and arm64) as the end address written to the annotate map file is computed as the start address of the symbol plus the size. Adding one could result in a curious failure where an entire function's contents in assembly was reduced instead to only the first instruction. The reason is that when the end instruction is bumped by one, objdump -d can append the first instruction of the next function in its output. However, since pmcannotate concatenates all of the objdump -d output from various functions into a single file which it then searches to find the assembly for a given file, if this additional trailer was earlier in the file than the full function, the trailer was chosen to represent the entire function resulting in the truncated listing of the function.

* Teach pmcannotate about $TMPDIR and _PATH_TMPAndrew Gallatin2018-05-181-2/+15
| | | | | | | | | | | | | Convert pmcannotate to using $TMPDIR and _PATH_TMP rather than hard coding /tmp for temporary files. Pmcannotate sometimes needs quite a lot of space to store the output from objdump, and will fail in odd ways if that output is truncated due to lack of space in /tmp.

* various: general adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-271-0/+2
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. No functional change intended.

Removing this rather unnecessary check which expects the second character of assembly line to be a hex number to make pmcannotate actually annotate the code and assembly.
