For PR797:
1. Actually turn on -fno-exceptions in libraries that do not have the REQUIRES_EH option in their Makefile. The following library file size savings were made (DEBUG): libLLVMDataStructure.a 525K libLLVMCore.a 380K libLLVMCodeGen.a 350K libLLVMTransformUtils.a 305K libLLVMScalarOpts.a 270K libLLVMAnalysis.a 247K libLLVMSelectionDAG.a 233K libLLVMipo.a 175K LLVMX86.o 123K LLVMPPC.o 81K libLLVMipa.a 17K TOTAL 2,706K Note that the savings is actually a little larger than this because I didn't count any of the libraries that had small changes. 2. Remove REQUIRES_EH from the AsmParser library as it is now exception free. This resulted in a nearly 78K drop in the size of the debug library for AsmParser. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29767 91177308-0d34-0410-b5e6-96231b3b80d8
