| | | | | | | | | Adjust usage of the ExecuteAndWait function to use the last argument which is the ErrMsg string. This is necessitated because this function no longer throws exceptions on error. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29791 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | Make sys::Program::ExecuteAndWait not throw exceptions and update any affected code. It now return -9999 to signal that the program couldn't be executed. Only one case (in bugpoint) actually examines the result code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29785 91177308-0d34-0410-b5e6-96231b3b80d8
* 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

* This commit adds a new feature called find-bugs. The find-bugs option can be ↵Patrick Jenkins2006-08-155-26/+73
| | | | | | 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
* Updating the comments above SplitFunctionsOutOfModule in ExtractFunction.cpp ↵Patrick Jenkins2006-07-281-5/+0
| | | | | | to reflect the changes made to that function. Specifically I am removing the FIXME comment because the issue has been addressed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29385 91177308-0d34-0410-b5e6-96231b3b80d8
* This commit improves bugpoints speed. On my G4 this changed caused kimwitu++ ↵Patrick Jenkins2006-07-281-15/+132
| | | | | | | | | to run through bugpoint in 1091.15 seconds (user + system time). The time it took to run this on my G4 before I made these changes is 1420.82 seconds (user + system time). This is a speedup of about 5.5 minutes. This is faster because SplitFunctionsOutOfModule no longer calls Clone Module and then removes the functions it doesnt want from the module returned. Instead it creates a module and copies over the specified functions, making changes to the new and old module where neccessary. This reduces the memory demand. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29379 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | 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
