[llvm-commits] make utils/GenLibDeps.pl ignore 'D' lines from nm

[Nick Lewycky]

GenLibDeps is showing that .so files all depend on each other. 
Technically, this hasn't caused a problem yet because neither libLTO.so 
nor libHello.so fir the 'libLLVM* or LLVM*' file convention, so they're 
both ignored by GenLibDeps entirely.

libLLVMgold is not so lucky. GenLibDeps concludes that everybody depends 
on libLLVMgold since it shows a 'D' record for __dso_handle. In my 
Debug/lib/ directory, the only D records come from .so files. The 
attached patch makes GenLibDeps ignore all D entries, and removes the 
apparent cycle encountered when building the gold plugin.

Comments?
