* For PR797:Reid Spencer2006-08-181-9/+4
| | | | | | | | | | | | | | 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

| | | | | | 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

* For PR351:Reid Spencer2005-12-221-11/+23
| | | | | | | | | | | | | 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

* Major addition to bugpoint: ability to debug code generators (LLC and LLI).Misha Brukman2003-07-241-2/+68
| | | | | | | | | | | | | | | | | | | | | | | | | The C backend is assumed correct and is used to generate shared objects to be loaded by the other two code generators. LLC debugging should be functional now, LLI needs a few more additions to work, the major one is renaming of external functions to call the JIT lazy function resolver. Bugpoint now has a command-line switch -mode with options 'compile' and 'codegen' to debug appropriate portions of tools. ExecutionDriver.cpp: Added implementations of AbstractInterpreter for LLC and GCC, broke out common code within other tools, and added ability to generate C code with CBE individually, without executing the program, and the GCC tool can generate executables shared objects or executables. If no reference output is specified to Bugpoint, it will be generated with CBE, because it is already assumed to be correct for the purposes of debugging using this method. As a result, many functions now accept as an optional parameter a shared object to be loaded in, if specified. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7293 91177308-0d34-0410-b5e6-96231b3b80d8
