2009-01-02Reimplement the old and horrible bison parser for .ll files with a niceChris Lattner
and clean recursive descent parser. This change has a couple of ramifications: 1. The parser code is about 400 lines shorter (in what we maintain, not including what is autogenerated). 2. The code should be significantly faster than the old code because we don't have to work around bison's poor handling of datatypes with ctors/dtors. This also makes the code much more resistant to memory leaks. 3. We now get caret diagnostics from the .ll parser, woo. 4. The actual diagnostics emited from the parser are completely different so a bunch of testcases had to be updated. 5. I now disallow "%ty = type opaque %ty = type i32". There was no good reason to support this, it was just an accident of the old implementation. I have no reason to think that anyone is actually using this. 6. The syntax for sticking a global variable has changed to make it unambiguous. I don't think anyone is depending on this since only clang supports this and it is not solid yet, so I'm not worried about anything breaking. 7. This gets rid of the last use of bison, and along with it the .cvs files. I'll prune this from the makefiles as a subsequent commit. There are a few minor cleanups that can be done after this commit (suggestions welcome!) but this passes dejagnu testing and is ready for its time in the limelight. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61558 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-08Generalize bugpoint's concept of a "safe" backend, and add optionsDan Gohman
to allow the "safe" backend to be run with a different path, and/or with different command-line options. This enables the following use cases: - bugpoint llc against an llc command from a different build - bugpoint llc against the same llc with different command-line options - and more... Also, document the existing "custom" interpreter options. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60681 91177308-0d34-0410-b5e6-96231b3b80d8

2007-02-07push bytecode decompressor out through APIs. Now the bytecode readerChris Lattner
api's look like this: ModuleProvider *getBytecodeModuleProvider( const std::string &Filename, ///< Name of file to be read BCDecompressor_t *BCDC = Compressor::decompressToNewBuffer, std::string* ErrMsg = 0, ///< Optional error message holder BytecodeHandler* H = 0 ///< Optional handler for reader events ); This is ugly, but allows a client to say: getBytecodeModuleProvider("foo", 0); If they do this, there is no dependency on the compression libraries, saving codesize. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34012 91177308-0d34-0410-b5e6-96231b3b80d8

2006-08-18For PR797:Reid Spencer
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
2006-08-15This commit adds a new feature called find-bugs. The find-bugs option can be ↵Patrick Jenkins
invoked on a .bc file from the command like with -find-bugs and a list of passes you wish to test. This procedure takes the set of optimization passes the user specifies, randomizes the passes, runs the passes on the specified .bc file, compiles the program, and finally runs the program checking its output vs the .bc file with no optimizations. This process repeats until either the user kills bugpoint or an error occurs in the optimizations, program complitation, or the running of the program. If an error occurs, bugpoint attempts to diagnose the error by eliminating passes that are not at fault and code that is not needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29703 91177308-0d34-0410-b5e6-96231b3b80d8

2005-12-22For PR351:Reid Spencer
Generally, remove use of fork/exec from bugpoint in favor of the portable sys::Program::ExecuteAndWait method. This change requires two new options to bugpoint to tell it that it is running in "child" mode. In this mode, it reads its input and runs the passes. The result code signals to the parent instance of bugpoint what happened (success, fail, crash). This change should make bugpoint usable on Win32 systems. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@24961 91177308-0d34-0410-b5e6-96231b3b80d8
