* BugDriver.h:Misha Brukman2003-07-283-43/+235
| | | | | | | | | | | | | | | | | | | | | | | | | | | * Added method to query if BugDriver is executing the JIT currently. This provides the ability in adding code that is conditionally executed in codegen debugging phase. CodeGeneratorBug.cpp: * Delete test functions from the Safe module * Code conditionally added when debugging the JIT: use the lazy resolver function added to Emitter.cpp to get function pointer by name. When compiled into an .so, this is the only way to get a pointer to an external function * Added a symbol disambiguator which will keep symbols uniquely named across modules * Delete generated files by default * The function `main' *must* stay in the .bc file for the JIT, but that prevents debugging it alone. This patch makes the old `main' become `old_main' and adds a new function named `main' which just calls the original with the same parameters, thereby keeping functionality the same. ExecutionDriver.cpp: * Returned to getting unique filenames * Simplified code choosing between using and not using shared library option git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7364 91177308-0d34-0410-b5e6-96231b3b80d8
