llvm.org.eclass
Description
The llvm.org eclass provides common code to fetch and unpack parts of the llvm.org project tree. It takes care of handling both git checkouts and source tarballs, making it possible to unify the code of live and release ebuilds and effectively reduce the work needed to package new releases/RCs/branches.
In order to use this eclass, the ebuild needs to declare LLVM_COMPONENTS and then call llvm.org_set_globals. If tests require additional components, they need to be listed in LLVM_TEST_COMPONENTS. The eclass exports an implementation of src_unpack() phase.
Example:
inherit llvm.org
LLVM_COMPONENTS=( lld )
LLVM_TEST_COMPONENTS=( llvm/utils/lit )
llvm.org_set_globals
Functions
- llvm.org_set_globals
-
Set global variables. This must be called after setting LLVM_* variables used by the eclass.
- llvm.org_src_unpack
-
Unpack or checkout requested LLVM components.
- llvm.org_src_prepare
-
Call appropriate src_prepare (cmake or default) depending on inherited eclasses. Make sure that PATCHES and user patches are applied in top ${WORKDIR}, so that patches straight from llvm-project repository work correctly with -p1.
- get_lit_flags
-
Get the standard recommended lit flags for running tests, in CMake list form (;-separated).
- llvm_manpage_dist_available
-
Return true (0) if this LLVM version features prebuilt manpage tarball, false (1) otherwise.
- llvm_are_manpages_built
-
Return true (0) if manpages are going to be built from source, false (1) if preinstalled manpages will be used.
- llvm_install_manpages
-
Install pregenerated manpages if available. No-op otherwise.
Variables
- LLVM_COMPONENTS (REQUIRED)
-
List of components needed unconditionally. Specified as bash array with paths relative to llvm-project git. Automatically translated for tarball releases.
The first path specified is used to construct default S.
- LLVM_TEST_COMPONENTS
-
List of additional components needed for tests.
- LLVM_MANPAGES
-
Set to a non-empty value in ebuilds that build manpages via Sphinx. The eclass will either include the dependency on dev-python/sphinx or pull the pregenerated manpage tarball depending on the package version.
- LLVM_PATCHSET
-
LLVM patchset version. No patchset is used if unset.
- LLVM_USE_TARGETS
-
Add LLVM_TARGETS flags. The following values are supported:
-
provide - this package provides LLVM targets. USE flags and REQUIRED_USE will be added but no dependencies.
-
llvm - this package uses targets from LLVM. RDEPEND+DEPEND on matching sys-devel/llvm versions with requested flags will be added.
Note that you still need to pass enabled targets to the build system, usually grabbing them from ${LLVM_TARGETS} (via USE_EXPAND).
-
- ALL_LLVM_EXPERIMENTAL_TARGETS (GENERATED BY ECLASS)
-
The complete list of LLVM experimental targets available in this LLVM version. The value depends on ${PV}.
- ALL_LLVM_PRODUCTION_TARGETS (GENERATED BY ECLASS)
-
The complete list of LLVM production-ready targets available in this LLVM version. The value depends on ${PV}.
- ALL_LLVM_TARGET_FLAGS (GENERATED BY ECLASS)
-
The list of USE flags corresponding to all LLVM targets in this LLVM version. The value depends on ${PV}.
- LIT_JOBS (USER VARIABLE)
-
Number of test jobs to run simultaneously. If unset, defaults to '-j' in MAKEOPTS. If that is not found, default to nproc.
