The following commit(s) were added to refs/heads/main by this push: new a155d0e Bug 40605: Reworked the macOS toolchain creation. a155d0e is described below commit a155d0e4a249089d1fe51bcfd621b699df2bca85 Author: Pier Angelo Vendrame <pierov@torproject.org> AuthorDate: Tue Aug 16 22:03:02 2022 +0200 Bug 40605: Reworked the macOS toolchain creation. We were compiling another Clang with the macOS toolchain, but we did not really need to, so I have removed that step. However, compiling compiler-rt was failing in this way, so I have disabled a pair of components we should not need. Probably, only the built-ins are actually needed. Finally, we now compile libc++ in the way LLVM currently suggests. --- projects/clang/build | 2 +- projects/macosx-toolchain/build | 105 +++++++++++++++++---------------------- projects/macosx-toolchain/config | 2 - 3 files changed, 47 insertions(+), 62 deletions(-) diff --git a/projects/clang/build b/projects/clang/build index 48cddec..8449070 100644 --- a/projects/clang/build +++ b/projects/clang/build @@ -25,7 +25,7 @@ mkdir build cd build cmake ../llvm -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX=$distdir \ -DCMAKE_BUILD_TYPE=Release \ - [% IF c("var/android") -%] + [% IF c("var/android") || c("var/osx") -%] -DLLVM_TARGETS_TO_BUILD="X86;ARM;AArch64" \ [% END -%] [% IF c("var/rlbox") -%]-DLLVM_EXPERIMENTAL_TARGETS_TO_BUILD=WebAssembly[% END %] \ diff --git a/projects/macosx-toolchain/build b/projects/macosx-toolchain/build index c4d1937..228d02d 100644 --- a/projects/macosx-toolchain/build +++ b/projects/macosx-toolchain/build @@ -5,78 +5,77 @@ mkdir $builddir distdir=/var/tmp/dist/[% project %] mkdir -p "$distdir" tar -C /var/tmp/dist -xf [% c('input_files_by_name/cmake') %] -tar -C /var/tmp/dist -xf [% c('input_files_by_name/ninja') %] -tar -C /var/tmp/dist -xf [% c('input_files_by_name/clang') %] +tar -C $distdir -xf [% c('input_files_by_name/clang') %] tar -C $distdir -xf [% c('input_files_by_name/SDK') %] tar -C $distdir -xf [% c('input_files_by_name/cctools') %] tar -C $builddir -xf [% c('input_files_by_name/llvm-project') %] arch=x86_64 -clangdir=/var/tmp/dist/clang/bin +clangdir=$distdir/clang/bin cctoolsdir=$distdir/cctools/bin sysrootdir=$distdir/MacOSX[% c("version") %].sdk/ target=x86_64-apple-darwin # We still need to put the cctoolsdir on the path.
