18 years agoSeveral Changes To Support Building llvm-config:
Reid Spencer [Thu, 20 Apr 2006 21:13:58 +0000 (21:13 +0000)]
Several Changes To Support Building llvm-config:
1. If Perl is not available, don't run Perl dependent targets.
2. Check in FinalLibDeps.txt for build environments that can't build it
   because there's no Perl processor.
3. Ensure that FinalLibDeps.txt depends on LibDeps.txt so it is
   automatically regenerated.
4. Support objdir != srcdir building.
