verify-patch-sanity.py validates every active recipe .patch has internally- consistent hunk line counts — catching the 'malformed patch at line N' failure at commit/CI/preflight time instead of hours into a cook. This cycle hit that class three times (qtwaylandscanner, sddm, xwayland), each only discovered when cookbook tried to apply the patch. Running it across the repo found 29 latent malformed patches (validated against GNU patch: e.g. relibc/P3-sysv-ipc reproduces 'malformed patch at line 22'). They were harmless only because they sit in vendored recipes (baked, not re- applied) — but would fail on any version-bump re-derivation. --fix recounts the hunk headers (body untouched) and repaired all 29. Wired into build-preflight.sh (Phase 1.0D) and redbear-ci.yml, with a unit test (test-patch-sanity.sh). Skips archived/legacy trees and unvalidatable formats (empty placeholders, bare-@@ git hunks).

|
|
================================================

|
|
|
SYNOPSIS
|
|
--------
|
|

|
:program:`llvm-profgen` [*commands*] [*options*]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
|
|
The :program:`llvm-profgen` utility generates a profile data file
|
|
from given perf script data files for sample-based profile guided
|
|
optimization(SPGO).
|
|
|
|
COMMANDS
|
|
--------
|
|
At least one of the following commands are required:
|
|
|
|
.. option:: --perfscript=<string[,string,...]>
|
|
|
|
Path of perf-script trace created by Linux perf tool with `script`
|
|
command(the raw perf.data should be profiled with -b).
|
|
|
|
.. option:: --binary=<string[,string,...]>
|
|
|
|
Path of the input profiled binary files.
|
|
|
|
.. option:: --output=<string>
|
|
|
|
Path of the output profile file.
|
|
|
|
OPTIONS
|
|
-------
|

:program:`llvm-profgen` supports the following options:
|
|
|
|
.. option:: --format=[text|binary|extbinary|compbinary|gcc]
|
|
|
|
Specify the format of the generated profile. Supported <format> are `text`,
|
|
`binary`, `extbinary`, `compbinary`, `gcc`, see `llvm-profdata` for more
|
|
descriptions of the format.
|
|
|
|
.. option:: --show-mmap-events
|
|
|
|
Print mmap events.
|
|

Print disassembled code.
|
|
|
|
.. option:: --x86-asm-syntax=[att|intel]
