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-config - Print LLVM compilation options
|
|
============================================
|
|
|
|
.. program:: llvm-config
|
|
|
|
SYNOPSIS
|
|
--------
|
|
|
|
**llvm-config** *option* [*components*...]
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
|
|
**llvm-config** makes it easier to build applications that use LLVM. It can
|
|
print the compiler flags, linker flags and object libraries needed to link
|
|
against LLVM.
|
|
|
|
EXAMPLES
|
|
--------
|
|
|
|
To link against the JIT:
|
|
|
|
.. code-block:: sh
|
|
|
|
g++ `llvm-config --cxxflags` -o HowToUseJIT.o -c HowToUseJIT.cpp
|
|
g++ `llvm-config --ldflags` -o HowToUseJIT HowToUseJIT.o \
|
|
`llvm-config --libs engine bcreader scalaropts`
|
|
|
|
OPTIONS
|
|
-------
|
|
|
|
**--assertion-mode**
|
|
|
|
Print the assertion mode used when LLVM was built (ON or OFF).
|
|
|
|
**--bindir**
|
|
|
|
Print the installation directory for LLVM binaries.
|
|
|
|
**--build-mode**
|
|
|
|
Print the build mode used when LLVM was built (e.g. Debug or Release).
|
|
|
|
**--build-system**
|
|
|
|
Print the build system used to build LLVM (e.g. `cmake` or `gn`).
|
|
|
|
**--cflags**
|
|
|
|
Print the C compiler flags needed to use LLVM headers.
|
|
|
|
**--cmakedir**
|
|
|
|
Print the installation directory for LLVM CMake modules.
|
|
|
|
**--components**
|
|
|
|
Print all valid component names.
|
|
|
|
**--cppflags**
|
|
|
|
Print the C preprocessor flags needed to use LLVM headers.
|
|
|
|
**--cxxflags**
|
|
|
|
Print the C++ compiler flags needed to use LLVM headers.
|
|
|
|
**--has-rtti**
|
|
|
|
Print whether or not LLVM was built with rtti (YES or NO).
|
|
|
|
**--help**
|
|
|
|
Print a summary of **llvm-config** arguments.
|
|
|
|
**--host-target**
|
|
|
|
Print the target triple used to configure LLVM.
|
|
|
|
**--ignore-libllvm**
|
|
|
|
Ignore libLLVM and link component libraries instead.
|
|
|
|
**--includedir**
|
|
|
|
Print the installation directory for LLVM headers.
|
|
|
|
**--ldflags**
|
|
|
|
Print the flags needed to link against LLVM libraries.
|
|
|
|
**--libdir**
|
|
|
|
Print the installation directory for LLVM libraries.
|
|
|
|
**--libfiles**
|
|
|
|
Similar to **--libs**, but print the full path to each library file. This is
|
|
useful when creating makefile dependencies, to ensure that a tool is relinked if
|
|
any library it uses changes.
|
|
|
|
**--libnames**
|
|
|
|
Similar to **--libs**, but prints the bare filenames of the libraries
|
|
without **-l** or pathnames. Useful for linking against a not-yet-installed
|
|
copy of LLVM.
|
|
|
|
**--libs**
|
|
|
|
Print all the libraries needed to link against the specified LLVM
|
|
*components*, including any dependencies.
|
|
|
|
**--link-shared**
|
|
|
|
Link the components as shared libraries.
|
|
|
|
**--link-static**
|
|
|
|
Link the component libraries statically.
|
|
|
|
**--obj-root**
|
|
|
|
Print the object root used to build LLVM.
|
|
|
|
**--prefix**
|
|
|
|
Print the installation prefix for LLVM.
|
|
|
|
**--shared-mode**
|
|
|
|
Print how the provided components can be collectively linked (`shared` or `static`).
|
|
|
|
**--system-libs**
|
|
|
|
Print all the system libraries needed to link against the specified LLVM
|
|
*components*, including any dependencies.
|
|
|
|
**--targets-built**
|
|
|
|
Print the component names for all targets supported by this copy of LLVM.
|
|
|
|
**--version**
|
|
|
|
Print the version number of LLVM.
|
|
|
|
|
|
COMPONENTS
|
|
----------
|
|
|
|
To print a list of all available components, run **llvm-config
|
|
--components**. In most cases, components correspond directly to LLVM
|
|
libraries. Useful "virtual" components include:
|
|
|
|
**all**
|
|
|
|
Includes all LLVM libraries. The default if no components are specified.
|
|
|
|
**backend**
|
|
|
|
Includes either a native backend or the C backend.
|
|
|
|
**engine**
|
|
|
|
Includes either a native JIT or the bitcode interpreter.
|
|
|
|
|
|
EXIT STATUS
|
|
-----------
|
|
|
|
If **llvm-config** succeeds, it will exit with 0. Otherwise, if an error
|
|
occurs, it will exit with a non-zero value.
