From 1b8eeb327e78f04b1c57b537a3a9534c91a9355b Mon Sep 17 00:00:00 2001 From: Bob Wilson Date: Thu, 10 Jan 2013 22:59:51 +0000 Subject: [PATCH] Update Apple's build script for llvmCore. This change is basically just copying changes that we've used for Apple's clang builds to the script used for building llvmCore. Besides cleaning it up to use xcrun to locate the proper versions of tools, especially for cross compiling, it fixes the build to work with newer versions of clang that honor SDKROOT settings in the environment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@172138 91177308-0d34-0410-b5e6-96231b3b80d8 --- utils/buildit/build_llvm | 128 ++++++++++++++++++++------------------- 1 file changed, 65 insertions(+), 63 deletions(-) diff --git a/utils/buildit/build_llvm b/utils/buildit/build_llvm index 6aee8310463..3d9364f5f0b 100755 --- a/utils/buildit/build_llvm +++ b/utils/buildit/build_llvm @@ -77,6 +77,37 @@ rm $SRC_DIR/Makefile || exit 1 # Now create our own by editing the top-level Makefile, deleting every line marked "Apple-style": sed -e '/[Aa]pple-style/d' -e '/include.*GNUmakefile/d' $ORIG_SRC_DIR/Makefile > $SRC_DIR/Makefile || exit 1 +SUBVERSION=`echo $RC_ProjectSourceVersion | sed -e 's/.*\.\([0-9]*\).*/\1/'` +if [ "x$SUBVERSION" != "x$RC_ProjectSourceVersion" ]; then + LLVM_SUBMIT_SUBVERSION=`printf "%02d" $SUBVERSION` + RC_ProjectSourceVersion=`echo $RC_ProjectSourceVersion | sed -e 's/\..*//'` + LLVM_SUBMIT_VERSION=$RC_ProjectSourceVersion +fi +if [ "x$LLVM_SUBMIT_SUBVERSION" = "x00" -o "x$LLVM_SUBMIT_SUBVERSION" = "x0" ]; then + LLVM_VERSION="$LLVM_SUBMIT_VERSION" +else + LLVM_VERSION="$LLVM_SUBMIT_VERSION-$LLVM_SUBMIT_SUBVERSION" +fi +LLVM_VERSION_INFO="'\" Apple Build #$LLVM_VERSION\"'" + +# Figure out how many make processes to run. +SYSCTL=`sysctl -n hw.activecpu` +# sysctl -n hw.* does not work when invoked via B&I chroot /BuildRoot. +# Builders can default to 2, since even if they are single processor, +# nothing else is running on the machine. +if [ -z "$SYSCTL" ]; then + SYSCTL=2 +fi +JOBS_FLAG="-j $SYSCTL" + +COMMON_CONFIGURE_OPTS="\ + --prefix=$DEST_DIR$DEST_ROOT \ + --enable-assertions=$LLVM_ASSERTIONS \ + --enable-optimized=$LLVM_OPTIMIZED \ + --disable-bindings" + +COMMON_MAKEFLAGS=$JOBS_FLAG $OPTIMIZE_OPTS UNIVERSAL=1 UNIVERSAL_ARCH="$HOSTS" UNIVERSAL_SDK_PATH=$SDKROOT NO_RUNTIME_LIBS=1 DISABLE_EDIS=1 REQUIRES_RTTI=1 DEBUG_SYMBOLS=1 LLVM_SUBMIT_VERSION=$LLVM_SUBMIT_VERSION LLVM_SUBMIT_SUBVERSION=$LLVM_SUBMIT_SUBVERSION CXXFLAGS=-DLLVM_VERSION_INFO="$LLVM_VERSION_INFO" VERBOSE=1 + # Build the LLVM tree universal. mkdir -p $DIR/obj-llvm || exit 1 cd $DIR/obj-llvm || exit 1 @@ -89,6 +120,7 @@ if [ "$ARM_HOSTED_BUILD" = yes ]; then for prog in ar nm ranlib strip lipo ld as ; do P=$DIR/bin/arm-apple-darwin$DARWIN_VERS-${prog} T=`xcrun -sdk $SDKROOT -find ${prog}` + ln -s $T $DIR/bin/$prog echo '#!/bin/sh' > $P || exit 1 echo 'exec '$T' "$@"' >> $P || exit 1 chmod a+x $P || exit 1 @@ -97,80 +129,56 @@ if [ "$ARM_HOSTED_BUILD" = yes ]; then for prog in clang clang++ ; do P=$DIR/bin/arm-apple-darwin$DARWIN_VERS-${prog} T=`xcrun -sdk $SDKROOT -find ${prog}` + ln -s $T $DIR/bin/$prog echo '#!/bin/sh' > $P || exit 1 echo 'exec '$T' -arch armv7 -isysroot '${SDKROOT}' "$@"' >> $P || exit 1 chmod a+x $P || exit 1 done PATH=$DIR/bin:$PATH -fi -if [ "$ARM_HOSTED_BUILD" = yes ]; then - configure_opts="--enable-targets=arm --host=arm-apple-darwin10 \ - --target=arm-apple-darwin10 --build=i686-apple-darwin10" -elif [ "$IOS_SIM_BUILD" = yes ]; then - # Use a non-standard "darwin_sim" host triple to trigger a cross-build. - configure_opts="--enable-targets=x86 --host=i686-apple-darwin_sim \ - --build=i686-apple-darwin10" + unset SDKROOT && \ + $SRC_DIR/configure $COMMON_CONFIGURE_OPTS \ + --enable-targets=arm \ + --host=arm-apple-darwin10 \ + --target=arm-apple-darwin10 \ + --build=i686-apple-darwin10 \ + --program-prefix="" \ + || exit 1 + + make $COMMON_MAKEFLAGS SDKROOT= + if [ $?
