framework: Add new USES=llvm to more easily depend on one an llvm port
USES=llvm supports two kinds of arguments: * mode <none>: defaults to build build: add a BUILD_DEPENDS on chosen llvm-port run: add a RUN_DEPENDS on chosen llvm-port lib: add a LIB_DEPENDS on chosen llvm-port * version <none>: defaults to ${LLVM_DEFAULT} number: use explicitly the specified version min=number: use specified min if ${LLVM_DEFAULT} is lower max=number: use specified max if ${LLVM_DEFAULT} is higher An example usage might be: USES= llvm or USES= llvm:13,build or USES= llvm:min=14,lib The following variables are exposed to be used in the ports tree at the moment: * LLVM_VERSION version chosen from the arguments to llvm.mk * LLVM_PORT chosen llvm port * LLVM_CONFIG llvm-config of the chosen port * LLVM_LIBLLVM libLLVM.so of the chosen port * LLVM_PREFIX installation prefix of the chosen port Reviewed by: manu, bapt Differential Revision: https://reviews.freebsd.org/D37728

USES=llvm has been added to more easily depend on llvm.
|
||||||
|
|
||||||
|
USES=llvm supports two kinds of arguments:
|
||||||
|
|
||||||
|
* mode
|
||||||
|
<none>: defaults to build
|
||||||
|
build: add a BUILD_DEPENDS on chosen llvm-port
|
||||||
|
run: add a RUN_DEPENDS on chosen llvm-port
|
||||||
|
lib: add a LIB_DEPENDS on chosen llvm-port
|
||||||
|
|
||||||
|
* version
|
||||||
|
<none>: defaults to ${LLVM_DEFAULT}
|
||||||
|
number: use explicitly the specified version
|
||||||
|
min=number: use specified min if ${LLVM_DEFAULT} is lower
|
||||||
|
max=number: use specified max if ${LLVM_DEFAULT} is higher
|
||||||
|
|
||||||
|
An example usage might be:
|
||||||
|
USES= llvm
|
||||||
|
or
|
||||||
|
USES= llvm:13,build
|
||||||
|
or
|
||||||
|
USES= llvm:min=14,lib
|
||||||
|
|
||||||
|
The following variables are exposed to be used in the ports tree at the moment:
|
||||||
|
* LLVM_VERSION version chosen from the arguments to llvm.mk
|
||||||
|
* LLVM_PORT chosen llvm port
|
||||||
|
* LLVM_CONFIG llvm-config of the chosen port
|
||||||
|
* LLVM_LIBLLVM libLLVM.so of the chosen port
|
||||||
|
* LLVM_PREFIX installation prefix of the chosen port

# Provides support to depend on LLVM
|
||||||
|
#
|
||||||
|
# It chooses the llvm port to be used based on the following constraint:
|
||||||
|
# 1) no constraints given => ${LLVM_DEFAULT}
|
||||||
|
# 2) exact constraint given => ${exact}
|
||||||
|
# 2) max constraint given && ${max} < ${LLVM_DEFAULT} => ${max}
|
||||||
|
# 3) min constraint given && ${LLVM_DEFAULT} < ${LLVM_DEFAULT} => ${LLVM_DEFAULT}
|
||||||
|
|
||||||
|
# Usage:
|
||||||
|
# USES= llvm - default version chosen
|
||||||
|
# USES= llvm:15 - exact constraint
|
||||||
|
# USES= llvm:min=9 - min constraint: max(min,default)
|
||||||
|
# USES= llvm:max=10 - max constraint: min(max,default)
|
||||||
|
# USES= llvm:min=10,max=11 - all constraint: max(min(max,default),default)
