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).

.. _build instructions:
|
|
|
|
The instructions on this page are aimed at vendors who ship Compiler-RT as part of an
|
|
operating system distribution, a toolchain or similar shipping vehicles. If you
|
|
are a user merely trying to use Compiler-RT in your program, you most likely want to
|
|
refer to your vendor's documentation, or to the general documentation for using
|
|
LLVM, Clang, the various santizers, etc.

CMake Options
|
|
=============
|
|
|
|
Here are some of the CMake variables that are used often, along with a
|
|
brief explanation and LLVM-specific notes. For full documentation, check the
|
|
CMake docs or execute ``cmake --help-variable VARIABLE_NAME``.
|
|
|
|
**CMAKE_BUILD_TYPE**:STRING
|
|
Sets the build type for ``make`` based generators. Possible values are
|
|
Release, Debug, RelWithDebInfo and MinSizeRel. On systems like Visual Studio
|
|
the user sets the build type with the IDE settings.
|
|
|
|
**CMAKE_INSTALL_PREFIX**:PATH
|
|
Path where LLVM will be installed if "make install" is invoked or the
|
|
"INSTALL" target is built.
|
|
|
|
**CMAKE_CXX_COMPILER**:STRING
|
|
The C++ compiler to use when building and testing Compiler-RT.

Compiler-RT specific options
|
|
-----------------------
|
|
|
|
.. option:: COMPILER_RT_INSTALL_PATH:PATH
|
|
|
|
**Default**: ```` (empty relative path)
|
|
|
|
Prefix for directories where built Compiler-RT artifacts should be installed.
|
|
Can be an absolute path, like the default empty string, in which case it is
|
|
relative ``CMAKE_INSTALL_PREFIX``. If setting a relative path, make sure to
|
|
include the ``:PATH`` with your ``-D``, i.e. use
|
|
``-DCOMPILER_RT_INSTALL_PATH:PATH=...`` not
|
|
``-DCOMPILER_RT_INSTALL_PATH=...``, otherwise CMake will convert the
|
|
path to an absolute path.
|
|
|
|
.. option:: COMPILER_RT_INSTALL_LIBRARY_DIR:PATH
|
|
|
|
**Default**: ``lib``
|
|
|
|
Path where built Compiler-RT libraries should be installed. If a relative
|
|
path, relative to ``COMPILER_RT_INSTALL_PATH``.
|
|
|
|
.. option:: COMPILER_RT_INSTALL_BINARY_DIR:PATH
|
|
|
|
**Default**: ``bin``
|
|
|
|
Path where built Compiler-RT executables should be installed. If a relative
|
|
path, relative to ``COMPILER_RT_INSTALL_PATH``.
|
|
|
|
.. option:: COMPILER_RT_INSTALL_INCLUDE_DIR:PATH
|
|
|
|
**Default**: ``include``
|
|
|
|
Path where Compiler-RT headers should be installed. If a relative
|
|
path, relative to ``COMPILER_RT_INSTALL_PATH``.
|
|
|
|
.. option:: COMPILER_RT_INSTALL_DATA_DIR:PATH
|
|
|
|
**Default**: ``share``
|
|
|
|
Path where Compiler-RT data should be installed. If a relative
|
|
path, relative to ``COMPILER_RT_INSTALL_PATH``.
|
|
|
|
.. _LLVM-specific variables:
|
|
|
|
LLVM-specific options
|
|
---------------------
|
|
|
|
.. option:: LLVM_LIBDIR_SUFFIX:STRING
|
|
|
|
Extra suffix to append to the directory where libraries are to be
|
|
installed. On a 64-bit architecture, one could use ``-DLLVM_LIBDIR_SUFFIX=64``
|
|
to install libraries to ``/usr/lib64``.
