Misha Brukman ce89b392c6 As per Chris, greatly simplify handling of external functions by using the
wrapper idea uniformly: we can use Value::replaceAllUsesWith() instead of
special-casing by class of user.

Misha Brukman 8301864215 Finally implement rewriting global initializers which use external functions
by creating an internal wrapper function with same signature as the external
function, and use it instead of the "real" function.

The wrapper then calls the external function using the same JIT function
resolution API that has been used before for rewriting instructions, since the
wrapper has an explicit call instruction which we can rewrite.

debugment of our nasty codegen issues.  :)

Chris Lattner a413b08580 Fix two pretty serious bugs:
1. Each time the loop extractor extracted a loop, we would leak a module.
  2. When we extracted a loop, we didn't add the new function to the list of
     miscompiled functions.  Thus if the bug was in a loop nest and we
     extracted it, we could actually *LOSE THE BUG*, which is very bad.

With these patches, bugpoint has successfully found a bug for me in a function
with several nested loops, and cut it down to just one of them. :) :)

Chris Lattner bcec7875fb After reducing a miscompiled program down to the functions which are being
miscompiled, try to use the loop extractor to reduce the program down to a
loop nest that is being miscompiled.  In practice, the loop extractor appears
to have too many bugs for this to be useful, but hopefully they will be fixed
soon...

 * Improve comments in ExtractFunction.cpp

Chris Lattner 2920100e4d I hate it when bugpoint is all ready to give me a bytecode file, then crashes
in final cleanups.  Then you had to run the whole mess again with
-disable-final-cleanups.

This makes bugpoint run the cleanups in a protected environment so that if
they crash, bugpoint itself doesn't crash.  This makes things much happier,
implements a FIXME, and gets rid of YABPO (yet another bugpoint option).

Misha Brukman 87154fdbc0 CodeGeneratorBug.cpp:
* Temporarily externing InputArgv to print it out for the benefit of LLI command
  needed to reproduce the result.
* Print out the list of functions currently being tested
* ListReducer now returns a bool if there was a failure, so test for it

ListReducer.h:
* Handle the case where there is no problem by returning true if failure is
  found. Also correctly handles the case when there is only 1 pass/function.

Miscompilation.cpp:
* ListReducer now returns a bool if there was a failure, so test for it

llvm-svn: 7380
2003-07-29 16:02:28 +00:00
Misha Brukman 123c8576e5 Implemented cleanups as suggested by Chris:
* Use Module::getNamedFunction() to delete "main" instead of using a loop
* Compare function pointers instead of function names to determine equivalence
* Simplified creation of a 2-element vector containing zeroes
* Manually performed LICM on code
* Added an abort() in case a function we're considering occurs in something that
  is not an instruction
* Use DEBUG() around code sections instead of just in a statement in a loop,
  because GCC's DCE may not be good enough to completely remove it in a release
  build
* Print out a command that can be directly copied-and-pasted to re-execute
* Instead of just checking if a symbol begins with a dot and fixing it
  accordingly, use Mangler and fix all the problems (invalid chars in C symbol
  names) entirely
* The new `main' function has external linkage

Misha Brukman 539f95933c BugDriver.h:
* 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

llvm-svn: 7364
2003-07-28 19:16:14 +00:00
Misha Brukman 0fd3172754 Made a bunch of cleanups, as per Chris' recommendations:
* Removed unused global and member variables
* Fixed comments (CodeGeneratorBug.cpp)
* Check for possibly failing GCC::create() and CBE::create()
* Remove generated files after diffing the output (e.g., shared object)
* Instead of using std::for_each, use explicit loops as std::for_each may
  duplicate the functor, and ours carries state
* Changed member var from cl::opt<std::string> to just std::string
* Fixed doxygen comments
* Fixed string comparisons to use [ str.empty() ] instead of [ str == "" ]
* Cache instances of CBE and GCC in BugDriver across compilations and executions
  while testing tools.

2003-07-24 21:59:10 +00:00
Misha Brukman d792c9bb46 Major addition to bugpoint: ability to debug code generators (LLC and LLI).
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.
