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).

llvm-cxxfilt - LLVM symbol name demangler
|
|
=========================================
|
|
|
|
.. program:: llvm-cxxfilt
|
|
|
|
SYNOPSIS
|
|
--------
|
|
|
|
:program:`llvm-cxxfilt` [*options*] [*mangled names...*]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
|
|
:program:`llvm-cxxfilt` is a symbol demangler that can be used as a replacement
|
|
for the GNU :program:`c++filt` tool. It takes a series of symbol names and
|
|
prints their demangled form on the standard output stream. If a name cannot be
|
|
demangled, it is simply printed as is.
|
|
|
|
If no names are specified on the command-line, names are read interactively from
|
|
the standard input stream. When reading names from standard input, each input
|
|
line is split on characters that are not part of valid Itanium name manglings,
|
|
i.e. characters that are not alphanumeric, '.', '$', or '_'. Separators between
|
|
names are copied to the output as is.
|
|
|
|
EXAMPLE
|
|
-------
|
|
|
|
.. code-block:: console
|
|
|
|
$ llvm-cxxfilt _Z3foov _Z3bari not_mangled
|
|
foo()
|
|
bar(int)
|
|
not_mangled
|
|
$ cat input.txt
|
|
| _Z3foov *** _Z3bari *** not_mangled |
|
|
$ llvm-cxxfilt < input.txt
|
|
| foo() *** bar(int) *** not_mangled |
|
|
|
|
OPTIONS
|
|
-------
|
|
|
|
.. option:: --format=<value>, -s
|
|
|
|
Mangling scheme to assume. Valid values are ``auto`` (default, auto-detect the
|
|
style) and ``gnu`` (assume GNU/Itanium style).
|
|
|
|
.. option:: --help, -h
|
|
|
|
Print a summary of command line options.
|
|
|
|
.. option:: --no-params, -p
|
|
|
|
Do not demangle function parameters or return types.
|
|
|
|
.. option:: --no-strip-underscore, -n
|
|
|
|
Do not strip a leading underscore. This is the default for all platforms
|
|
except Mach-O based hosts.
|
|
|
|
.. option:: --quote
|
|
|
|
Add `"` `"` around demangled names. Do not quote already quoted names.
|
|
|
|
.. option:: --strip-underscore, -_
|
|
|
|
Strip a single leading underscore, if present, from each input name before
|
|
demangling. On by default on Mach-O based platforms.
|
|
|
|
.. option:: --types, -t
|
|
|
|
Attempt to demangle names as type names as well as symbol names.
|
|
|
|
.. option:: --version
|
|
|
|
Display the version of the :program:`llvm-cxxfilt` executable.
|
|
|
|
.. option:: @<FILE>
|
|
|
|
Read command-line options from response file `<FILE>`.
|
|
|
|
EXIT STATUS
|
|
-----------
|
|
|
|
:program:`llvm-cxxfilt` returns 0 unless it encounters a usage error, in which
|
|
case a non-zero exit code is returned.
