I checked with gcc people in my team and here is what they have to say. omjavaid, gcc-ar is a version of ar with LTO support omjavaid, ar is just ar omjavaid, likewise with gcc-nm and gcc-ranlib omjavaid, ar comes from binutils, gcc-ar comes from gcc
I agree with all other points you raised except for using gcc-ar in all cases. We should decide between ar (binutils) or gcc-ar (LTO support gcc packaged). Also present code doesnt generate obcopy-4.8 for me when i specify gcc-4.8. If it does for you let me know. https://reviews.llvm.org/D20386 _______________________________________________ lldb-commits mailing list lldb-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-commits
