sys-libs/compiler-rt: Add slotted version Introduce a slotted variant of compiler-rt libraries with the slot matching the clang version. This will make it possible to install a new compiler-rt version before upgrading clang to the corresponding version, therefore preserving a working compiler through (even minor) clang upgrades. The alternative was to replace the complete version number with the major version in the runtime directory path. However, software (e.g. Mesa) hardcodes the default path and therefore breaks when it is changed. ..._rc1.ebuild => compiler-rt-4.0.0_rc1-r1.ebuild} | 36 ++++++++-------------- sys-libs/compiler-rt/compiler-rt-9999.ebuild | 36 ++++++++-------------- 2 files changed, 26 insertions(+), 46 deletions(-) diff --git a/sys-libs/compiler-rt/compiler-rt-4.0.0_rc1.ebuild b/sys-libs/compiler-rt/compiler-rt-4.0.0_rc1-r1.ebuild similarity index 76% rename from sys-libs/compiler-rt/compiler-rt-4.0.0_rc1.ebuild rename to sys-libs/compiler-rt/compiler-rt-4.0.0_rc1-r1.ebuild index 49f12b097e..43560c2edd 100644 --- a/sys-libs/compiler-rt/compiler-rt-4.0.0_rc1.ebuild +++ b/sys-libs/compiler-rt/compiler-rt-4.0.0_rc1-r1.ebuild @@ -17,16 +17,16 @@ HOMEPAGE="http://llvm.org/"; SRC_URI="http://www.llvm.org/pre-releases/${PV/_//}/${P/_/}.src.tar.xz"; LICENSE="|| ( UoI-NCSA MIT )" -SLOT="0/${PV%.*}" +SLOT="${PV%_*}" KEYWORDS="~amd64 ~arm64 ~x86" IUSE="test" -RDEPEND=" - !<sys-devel/llvm-4" +LLVM_SLOT=${SLOT%%.*} +RDEPEND="!=sys-libs/compiler-rt-${SLOT}*:0" # llvm-4 needed for --cmakedir -DEPEND="${RDEPEND} +DEPEND=" >=sys-devel/llvm-4 - test?
