Pier Angelo Vendrame pushed to branch main at The Tor Project / Applications / tor-browser-build Commits: d940f9db by Pier Angelo Vendrame at 2023-01-19T15:18:08+01:00 Bug 40353: Re-enable rlbox Updated the creation of the WASI sysroot, to be more similar to what Mozilla does in shell scripts included in Firefox source code. This includes the same hacks, like re-using the LLVM we already build. We were still using lucetc, which is not needed anymore. Therefore, this commit removes it. - - - - - 17 changed files: - Makefile - projects/clang/build - projects/firefox/build - projects/firefox/config - projects/firefox/list_toolchain_updates_checks - projects/geckoview/build - projects/geckoview/config - − projects/lucetc/Remove-march-native-from-COMMON_CFLAGS.patch - − projects/lucetc/build - − projects/lucetc/config - + projects/wasi-config/build - + projects/wasi-config/config - + projects/wasi-libc/build - + projects/wasi-libc/config - projects/wasi-sysroot/build - projects/wasi-sysroot/config - rbm.conf Changes: ===================================== Makefile ===================================== @@ -274,9 +274,6 @@ cargo_vendor-cbindgen-android: submodule-update cargo_vendor-cbindgen: submodule-update $(rbm) build cbindgen --step cargo_vendor --target nightly --target torbrowser-linux-x86_64 -cargo_vendor-lucetc: submodule-update - $(rbm) build lucetc --step cargo_vendor --target nightly --target torbrowser-linux-x86_64 - cargo_vendor-uniffi-rs: submodule-update $(rbm) build uniffi-rs --step cargo_vendor --target nightly --target torbrowser-linux-x86_64 ===================================== projects/clang/build ===================================== @@ -24,7 +24,7 @@ cd build cmake ../llvm -GNinja \ -DCMAKE_INSTALL_PREFIX=$distdir \ -DCMAKE_BUILD_TYPE=Release \ - -DLLVM_TARGETS_TO_BUILD="X86;ARM;AArch64[% IF c("var/rlbox") -%];WebAssembly[% END %]" \ + -DLLVM_TARGETS_TO_BUILD="X86;ARM;AArch64;WebAssembly" \ -DLLVM_ENABLE_PROJECTS="clang;lld" \ -DLLVM_ENABLE_ZLIB=ON \ -DLLVM_INSTALL_UTILS=ON \ ===================================== projects/firefox/build ===================================== @@ -49,10 +49,7 @@ export PATH="/var/tmp/dist/rust/bin:/var/tmp/dist/cbindgen:/var/tmp/dist/nasm/bi rtdir=/var/tmp/dist/clang/lib/clang/[% pc("clang", "version") %]/lib/wasi [% END -%] mkdir -p $rtdir - cp /var/tmp/dist/wasi-sysroot/lib/clang/11.0.0/lib/wasi/libclang_rt.builtins-wasm32.a $rtdir - tar -C /var/tmp/dist -xf [% c('input_files_by_name/lucetc') %] - export PATH="/var/tmp/dist/lucetc/bin:$PATH" - export WASM_SANDBOXED_LIBRARIES=graphite,ogg + cp /var/tmp/dist/wasi-sysroot/lib/clang/*/lib/wasi/libclang_rt.builtins-wasm32.a $rtdir export WASI_SYSROOT=/var/tmp/dist/wasi-sysroot/share/wasi-sysroot [% END -%] ===================================== projects/firefox/config ===================================== @@ -158,9 +158,6 @@ input_files: - project: wasi-sysroot name: wasi-sysroot enable: '[% c("var/rlbox") %]' - - project: lucetc - name: lucetc - enable: '[% c("var/rlbox") %]' - project: node name: node - project: nasm ===================================== projects/firefox/list_toolchain_updates_checks ===================================== @@ -213,15 +213,5 @@ needed=$(perl -MYAML::XS -e "$p") current='[% pc("wasi-sysroot", "git_hash") %]' check_update_needed wasi-sdk "$needed" "$current" - -# lucetc -read -d '' p << 'EOF' || true -my $d = YAML::XS::LoadFile('taskcluster/ci/fetch/toolchains.yml');
