This feels rather unpleasant to me. Is it likely that someone will have programs called llc-3.0 etc, but no llc?
Yes, Ubuntu 12.04 LTS installs LLVM 3.0 package in a way that, the package binaries are installed into /usr/lib/llvm-3.0 directory and inside /usr/bin there are llc-3.0 and opt-3.0 links created linking to ../lib/llvm-3.0/bin/{llc|opt}.
So David is fixing real-world issue here.
But if you install 'llvm' (rather than 'llvm-3.0') then you get a /usr/bin/llc Analogously, on ubuntu, if you install 'gcc' then you get /usr/bin/gcc, but if you install 'gcc-4.6' then you get /usr/bin/gcc-4.6; but we don't search for gcc-* executables. Thanks Ian
