From 110c2528709ee10466a6b4bee5a2adefe11a0c3f Mon Sep 17 00:00:00 2001 From: Dan Peebles Date: Sat, 15 Sep 2018 16:49:44 -0400 Subject: cctools: support LTO on Darwin LTO is disabled during bootstrap to keep the bootstrap tools small and avoid unnecessary LLVM rebuilds, but is enabled in the final stdenv stage and should be usable by normal packages. --- pkgs/development/compilers/llvm/5/llvm.nix | 4 +++- pkgs/os-specific/darwin/apple-source-releases/ICU/default.nix | 4 +--- pkgs/os-specific/darwin/apple-source-releases/default.nix | 2 +- pkgs/os-specific/darwin/cctools/port.nix | 4 ++-- pkgs/stdenv/darwin/default.nix | 1 + pkgs/stdenv/darwin/make-bootstrap-tools.nix | 10 +++++++--- 6 files changed, 15 insertions(+), 10 deletions(-) diff --git a/pkgs/development/compilers/llvm/5/llvm.nix b/pkgs/development/compilers/llvm/5/llvm.nix index 3abba0ed340..6dae8be97c8 100644 --- a/pkgs/development/compilers/llvm/5/llvm.nix +++ b/pkgs/development/compilers/llvm/5/llvm.nix @@ -119,12 +119,14 @@ in stdenv.mkDerivation (rec { + stdenv.lib.optionalString enableSharedLibraries '' moveToOutput "lib/libLLVM-*" "$lib" moveToOutput "lib/libLLVM${stdenv.hostPlatform.extensions.sharedLibrary}" "$lib" + moveToOutput "lib/libLTO${stdenv.hostPlatform.extensions.sharedLibrary}" "$lib" substituteInPlace "$out/lib/cmake/llvm/LLVMExports-${if debugVersion then "debug" else "release"}.cmake" \ --replace "\''${_IMPORT_PREFIX}/lib/libLLVM-" "$lib/lib/libLLVM-" '' + stdenv.lib.optionalString (stdenv.isDarwin && enableSharedLibraries) '' substituteInPlace "$out/lib/cmake/llvm/LLVMExports-${if debugVersion then "debug" else "release"}.cmake" \ - --replace "\''${_IMPORT_PREFIX}/lib/libLLVM.dylib" "$lib/lib/libLLVM.dylib" + --replace "\''${_IMPORT_PREFIX}/lib/libLLVM.dylib" "$lib/lib/libLLVM.dylib" \ + --replace "\''${_IMPORT_PREFIX}/lib/libLTO.dylib" "$lib/lib/libLTO.dylib" ln -s $lib/lib/libLLVM.dylib $lib/lib/libLLVM-${shortVersion}.dylib ln -s $lib/lib/libLLVM.dylib $lib/lib/libLLVM-${release_version}.dylib ''; diff --git a/pkgs/os-specific/darwin/apple-source-releases/ICU/default.nix b/pkgs/os-specific/darwin/apple-source-releases/ICU/default.nix index 89ff68266a2..761ff3ea925 100644 --- a/pkgs/os-specific/darwin/apple-source-releases/ICU/default.nix +++ b/pkgs/os-specific/darwin/apple-source-releases/ICU/default.nix @@ -1,8 +1,6 @@ -{ cctools, appleDerivation }: +{ appleDerivation }: appleDerivation { - nativeBuildInputs = [ cctools ]; - patches = [ ./clang-5.patch ]; postPatch = '' diff --git a/pkgs/os-specific/darwin/apple-source-releases/default.nix b/pkgs/os-specific/darwin/apple-source-releases/default.nix index d490048c4df..4fa0c0e3e47 100644 --- a/pkgs/os-specific/darwin/apple-source-releases/default.nix +++ b/pkgs/os-specific/darwin/apple-source-releases/default.nix @@ -215,7 +215,7 @@ let # Splicing is currently broken in Nixpkgs # cctools need to be specified manually here to handle this - ICU = applePackage "ICU" "osx-10.10.5" "1qihlp42n5g4dl0sn0f9pc0bkxy1452dxzf0vr6y5gqpshlzy03p" { inherit (buildPackages.darwin) cctools; }; + ICU = applePackage "ICU" "osx-10.10.5" "1qihlp42n5g4dl0sn0f9pc0bkxy1452dxzf0vr6y5gqpshlzy03p" {}; IOKit = applePackage "IOKit" "osx-10.11.6" "0kcbrlyxcyirvg5p95hjd9k8a01k161zg0bsfgfhkb90kh2s8x00" { inherit IOKitSrcs; }; launchd = applePackage "launchd" "osx-10.9.5" "0w30hvwqq8j5n90s3qyp0fccxflvrmmjnicjri4i1vd2g196jdgj" {}; diff --git a/pkgs/os-specific/darwin/cctools/port.nix b/pkgs/os-specific/darwin/cctools/port.nix index fff6eaaa5c1..bad17cf6de4 100644 --- a/pkgs/os-specific/darwin/cctools/port.nix +++ b/pkgs/os-specific/darwin/cctools/port.nix @@ -1,5 +1,5 @@ { stdenv, fetchFromGitHub, autoconf, automake, libtool_2, autoreconfHook -, libcxxabi, libuuid +, libcxxabi, libuuid, llvm , libobjc ?
