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).

opt - LLVM optimizer
|
|
====================
|
|
|
|
.. program:: opt
|
|
|
|
SYNOPSIS
|
|
--------
|
|
|
|
:program:`opt` [*options*] [*filename*]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
|
|
The :program:`opt` command is the modular LLVM optimizer and analyzer. It takes
|
|
LLVM source files as input, runs the specified optimizations or analyses on it,
|
|
and then outputs the optimized file. The optimizations available via
|
|
:program:`opt` depend upon what libraries were linked into it as well as any
|
|
additional libraries that have been loaded with the :option:`-load` option. Use
|
|
the :option:`-help` option to determine what optimizations you can use.
|
|
|
|
If ``filename`` is omitted from the command line or is "``-``", :program:`opt`
|
|
reads its input from standard input. Inputs can be in either the LLVM assembly
|
|
language format (``.ll``) or the LLVM bitcode format (``.bc``).
|
|
|
|
If an output filename is not specified with the :option:`-o` option,
|
|
:program:`opt` writes its output to the standard output.
|
|
|
|
OPTIONS
|
|
-------
|
|
|
|
.. option:: -f
|
|
|
|
Enable binary output on terminals. Normally, :program:`opt` will refuse to
|
|
write raw bitcode output if the output stream is a terminal. With this option,
|
|
:program:`opt` will write raw bitcode regardless of the output device.
|
|
|
|
.. option:: -help
|
|
|
|
Print a summary of command line options.
|
|
|
|
.. option:: -o <filename>
|
|
|
|
Specify the output filename.
|
|
|
|
.. option:: -S
|
|
|
|
Write output in LLVM intermediate language (instead of bitcode).
|
|
|
|
.. option:: -{passname}
|
|
|
|
:program:`opt` provides the ability to run any of LLVM's optimization or
|
|
analysis passes in any order. The :option:`-help` option lists all the passes
|
|
available. The order in which the options occur on the command line are the
|
|
order in which they are executed (within pass constraints).
|
|
|
|
.. option:: -strip-debug
|
|
|
|
This option causes opt to strip debug information from the module before
|
|
applying other optimizations. It is essentially the same as `-strip`
|
|
but it ensures that stripping of debug information is done first.
|
|
|
|
.. option:: -verify-each
|
|
|
|
This option causes opt to add a verify pass after every pass otherwise
|
|
specified on the command line (including `-verify`). This is useful
|
|
for cases where it is suspected that a pass is creating an invalid module but
|
|
it is not clear which pass is doing it.
|
|
|
|
.. option:: -stats
|
|
|
|
Print statistics.
|
|
|
|
.. option:: -time-passes
|
|
|
|
Record the amount of time needed for each pass and print it to standard
|
|
error.
|
|
|
|
.. option:: -debug
|
|
|
|
If this is a debug build, this option will enable debug printouts from passes
|
|
which use the ``LLVM_DEBUG()`` macro. See the `LLVM Programmer's Manual
|
|
<../ProgrammersManual.html>`_, section ``#DEBUG`` for more information.
|
|
|
|
.. option:: -load=<plugin>
|
|
|
|
Load the dynamic object ``plugin``. This object should register new
|
|
optimization or analysis passes. Once loaded, the object will add new command
|
|
line options to enable various optimizations or analyses. To see the new
|
|
complete list of optimizations, use the :option:`-help` and :option:`-load`
|
|
options together. For example:
|
|
|
|
.. code-block:: sh
|
|
|
|
opt -load=plugin.so -help
|
|
|
|
.. option:: -print-passes
|
|
|
|
Print all available passes and exit.
|
|
|
|
EXIT STATUS
|
|
-----------
|
|
|
|
If :program:`opt` succeeds, it will exit with 0. Otherwise, if an error
|
|
occurs, it will exit with a non-zero value.
