[Octave-patch-tracker] [patch #8395] Work-in-progress port of Octave JIT to libgccjit

[Stefan Mahr]

Follow-up Comment #6, patch #8395 (project octave):

I rebased your patch and added some autoconf magic. Compiling is successful,
but running octave leads to SIGABRT.


libgccjit.so: error: gcc_jit_context_new_call: mismatching types for argument
3 of function "octave_jit_call": assignment to param arg2 (type: struct
octave_base_value * *) from tmp_array (type: struct octave_base_value *[1])
gcc_jit_rvalue_as_object: NULL rvalue
terminate called after throwing an instance of 'gccjit::error'

Program received signal SIGABRT, Aborted.

I built gccjit and octave with this script:


CURDIR=$(pwd)

# clone repositories
cd ${CURDIR}
git clone git://gcc.gnu.org/git/gcc.git gcc-src
cd gcc-src
git checkout dmalcolm/jit

cd ${CURDIR}
hg clone http://octave.org/hg/octave octave-src
cd octave-src
hg pull http://hg.octave.org/octave-nkf
hg up gccjit
./bootstrap


LIBGCCJIT_PREFIX=${CURDIR}/gccjit-install

# gccjit
cd ${CURDIR}
rm -rf gcc-build
mkdir -p gcc-build
cd gcc-build
../gcc-src/configure 
        --prefix=${LIBGCCJIT_PREFIX} 
        --enable-host-shared 
        --enable-languages=jit 
        --disable-bootstrap

make -j8
make install


# octave
cd ${CURDIR}
export LD_LIBRARY_PATH=${LIBGCCJIT_PREFIX}/lib:$LD_LIBRARY_PATH
rm -rf octave-build
mkdir -p octave-build
cd octave-build
../octave-src/configure 
        --prefix=${LIBGCCJIT_PREFIX} 
        --enable-jit 
        --disable-gui 
        FFLAGS=-g CFLAGS=-g CXXFLAGS=-g --enable-bounds-check 
        LIBGCCJIT_PREFIX=${LIBGCCJIT_PREFIX}

make -j8

./run-octave -g
