Hi! This week I’ve pretty much finished the work on LLVM\/Clang support
\nfor Crossdev and LLVM-libc ebuild(s). I have sent PRs for Crossdev and
\nrelated ebuild changes here:<\/p>\n
https:\/\/github.com\/gentoo\/crossdev\/pull\/10
\nhttps:\/\/github.com\/gentoo\/gentoo\/pull\/32136
\nThis PR includes changes for compiler-rt which are always needed for
\nClang crossdev, regardless of libc. There are also changes to musl,
\nkernel-2.eclass (for linux-headers), and a new eclass, cross.eclass.<\/p>\n
I made a gentoo.git branch that has LLVM-libc, libc-hdrgen ebuilds and a
\ngnuconfig patch to support
\nLLVM-libc. https:\/\/github.com\/gentoo\/gentoo\/compare\/master…alfredfo:gentoo:gentoo-llvm-libc. I
\nwant to merge Crossdev changes and ebuilds before merging
\nthis. Previously all autotools based projects would fail to configure on
\nLLVM-libc because there was no gnuconfig entry for it.<\/p>\n
I have also solved the problem from last week not being able to compile SCUDO
\ninto LLVM-libc directly. This was caused by two things, 1) LLVM-libc
\nonly checked for compiler-rt in LLVM_ENABLE_PROJECTS, not
\nLLVM_ENABLE_RUNTIMES which is needed for using “llvm-project\/runtimes”
\nas root source directory (“Runtimes build”).
\nFix commit:
\nhttps:\/\/github.com\/llvm\/llvm-project\/commit\/fe9c3c786837de74dc936f8994cd5a53dd8ee708
\n2) Many compiler-rt configure tests would fail because of LLVM-libc not
\nsupporting dynamic linking, and therefore disable the build of
\nSCUDO. This was fixed by passing
\n-DCMAKE_TRY_COMPILE_TARGET_TYPE=STATIC_LIBRARY. So now I no longer need
\nto manually compile the source files and append object files into
\nlibc.a, yay!<\/p>\n
Now I will continue to fix packages for using LLVM-libc Crossdev, or
\nmore likely, add needed functionality into LLVM-libc. I will of course
\nalso fix any comments I get on my PRs.<\/p>\n
