I'm not sure whether I mentioned it before, but I didn't manage to build a working llvm/clang from its svn last weekend (I tried about three revisions and all of them failed to build with syntax errors, so I gave up for the moment). Do they not have a checkin policy that code needs to compile at least? Anyway, it's good that you did some testing here. Can you please also test the Libtool package with this: > ./configure > CC=/home/edwin/llvm2.7/llvm-gcc-4.2-2.7-x86_64-linux/bin/llvm-gcc > CXX=/home/edwin/llvm2.7/llvm-gcc-4.2-2.7-x86_64-linux/bin/llvm-g++ > CFLAGS="-O4 -use-gold-plugin" CXXFLAGS="-O4 -use-gold-plugin" and run its testsuites and report results (see README for how)? Thanks. > ac_cv_c_fpu_bigendian=no How come you need to use that, and which Autoconf version do you use? This sounds like it needs to be addressed in Autoconf. Thanks. > Everything worked fine, and make check passed too! > (Now of course it didn't LTO the entire program because > -fuse-linker-plugin triggers PR41584) AFAIK -fuse-linker-plugin does not trigger PR 41584, only -fwhopr does. Did you mean one of the other ones? Cheers, Ralf
