Tobi,
I am confused by the configure code that sets CFLAGS to -O1 when
gcc 4.2.x is in use. Reverting this change on x86_64-apple-darwin10
still allows cloog 0.16.1 to build on x86_64-apple-darwin10 without
any regressions in the cloog testsuite. This is built against the
gcc 4.2.1 compiler in Xcode 3.2.5. I also find that building against
gcc-4.2 and g++-4.2 from Xcode 3.1.4 under powerpc-apple-darwin9
produces no cloog testsuite failures. Perhaps the cloog/isl/configure
test could be enhanced to not set -O1 if the gcc 4.2.x is "Apple Inc. build"
since Apple uses a very forked branch of gcc 4.2.1...
gcc -v
Using built-in specs.
Target: i686-apple-darwin10
Configured with: /var/tmp/gcc/gcc-5664~89/src/configure --disable-checking --enable-werror --prefix=/usr --mandir=/share/man --enable-languages=c,objc,c++,obj-c++ --program-transform-name=/^[cg][^.-]*$/s/$/-4.2/ --with-slibdir=/usr/lib --build=i686-apple-darwin10 --program-prefix=i686-apple-darwin10- --host=x86_64-apple-darwin10 --target=i686-apple-darwin10 --with-gxx-include-dir=/include/c++/4.2.1
Thread model: posix
gcc version 4.2.1 (Apple Inc. build 5664)
I'll test current gcc trunk built with -enable-cloog-backend=isl against
a -O3 isl build to check for regressions in graphite.
