Eliminate exception throwing from Path::renamePathOnDisk and adjust its users correspondingly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29843 91177308-0d34-0410-b5e6-96231b3b80d8
2006-08-23Make the ProgramName variable a std::string so we can eliminate the pathReid Spencer
portion fo the program name via sys::Path().getLast(). This makes error messages more readable since this is invariably used only in error messages. Instead of: /path/to/llvm/bin/directory/toolname: error message we will now get: toolname: error message Also, since we always have a program name (even if its defaulted), don't check to see if it is set or not when generating error messages. This eliminates a bunch of constant strings, saving a little under 1K of data. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29842 91177308-0d34-0410-b5e6-96231b3b80d8

Adjust the use of MappedFile to its new non-throwing interface. We just propagate the exceptions if an error occurs. This will get cleaned up later, incrementally. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29820 91177308-0d34-0410-b5e6-96231b3b80d8

Make the Bytecode Reader use setjmp/longjump instead of exceptions to handle errors. The alternative was even uglier than setjmp/longjump as it would impact the interface and workings of nearly every function in the reader. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29819 91177308-0d34-0410-b5e6-96231b3b80d8

2006-08-22For PR797:Reid Spencer
Adjust users of MappedFile to its new non-throwing interface. Note that in most cases the lazy step of just throwing after a call to MappedFile was installed. This was done in the name of incremental changes. Getting rid of the new throw statements will take adjustment of interfaces and propagation of errors to higher levels. Those changes will come in subsequent patches. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29817 91177308-0d34-0410-b5e6-96231b3b80d8

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

Rid the Assembly Parser of exceptions. This is a really gross hack but it will do until the Assembly Parser is re-written as a recursive descent. The basic premise is that wherever the old "ThrowException" function was called (new name: GenerateError) we set a flag (TriggerError). Every production checks that flag and calls YYERROR if it is set. Additionally, each call to ThrowException in the grammar is replaced with GEN_ERROR which calls GenerateError and then YYERROR immediately. This prevents the remaining production from continuing after an error condition. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29763 91177308-0d34-0410-b5e6-96231b3b80d8
