You have been subscribed to a public bug by Alexander Sack (asac): Attached is the .i file that causes the ICE. It occurs when using a Linaro GCC 4.6-2011.06-0 based Android toolchain to compile the bionic libm. A prebuilt toolchain can be found at: https://android-build.linaro.org/builds/~linaro-android/toolchain-4.6-2011.06-0/
I think it has been built like this (at least I was able to reproduce the ICE using the following steps): mkdir linaro-4.6-toolchain && cd linaro-4.6-toolchain mkdir bin wget -O bin/repo http://android.git.kernel.org/repo chmod a+x bin/repo export PATH="`pwd`/bin:$PATH" repo init -u git://git.linaro.org/android/toolchain/manifest.git repo sync LINARO_BUILD_EXTRA_CONFIGURE_FLAGS=--disable-libquadmath build/linaro-build.sh --with-gcc="http://launchpad.net/gcc-linaro/4.6/4.6-2011.06-0/+download/gcc-linaro-4.6-2011.06-0.tar.bz2"; --prefix=`readlink -f $(pwd)/../linaro-4.6-toolchain-install` &> build_$(date +%Y-%m-%d_%H-%M).log & These are the flags to get the ICE: ../linaro-4.6-toolchain-install/bin/arm-eabi-gcc -c -march=armv7-a -mfloat-abi=softfp -mfpu=neon -g -O1 e_cosh.i You get something like this: bionic/libm/src/e_cosh.c: In function 'cosh': bionic/libm/src/e_cosh.c:86:1: internal compiler error: Segmentation fault One interesting detail is that it works when using the Linaro GCC 4.6-2011.05-0 (http://launchpad.net/gcc- linaro/4.6/4.6-2011.05-0/+download/gcc-linaro-4.6-2011.05-0.tar.bz2). ** Affects: gcc-linaro Importance: Undecided Assignee: Richard Sandiford (rsandifo) Status: In Progress -- Linaro GCC 4.6-2011.06-0 gets ICE when compiling bionic's libm https://bugs.launchpad.net/bugs/809768 You received this bug notification because you are a member of Linaro Release Team, which is subscribed to the bug report. _______________________________________________ Mailing list: https://launchpad.net/~linaro-release Post to : [email protected] Unsubscribe : https://launchpad.net/~linaro-release More help : https://help.launchpad.net/ListHelp
