Chris Lattner 5e166a5f3e Fix a bugpoint crash that JeffC noticed, looking like this:
*** Attempting to perform final cleanups: Final cleanups failed.  Sorry. :(  Ple
ase report a bug!

<llc>llc.exe: bytecode didn't read correctly.
llc.exe: bytecode didn't read correctly.
<crash>
Assertion failed: M && "You can't write a null module!!", file c:\llvm\lib\bytec
ode\writer\writer.cpp, line 1094


The fact that llc bombed (in this case) is ok, but bugpoint shouldn't crash after this.

* Place a try/catch block around the entire tool to Make sure std::string
  exceptions are caught and printed before exiting the tool.
* Make sure we catch unhandled exceptions at the top level so that we don't
  abort with a useless message but indicate than an unhandled exception was
  generated.

llvm-svn: 13475
2004-05-12 02:43:24 +00:00
Chris Lattner a060b10ee5 Implement basic block extraction for the miscompilation debugger. This still needs
two things: the FIXME in ExtractBlocks needs to be implemented, and the basic block
extractor itself needs to have enough bugs fixed for this to be more or less
useful.

Until the time that this is generally useful, it is hidden behind the new bugpoint
-enable-block-extraction option.  I hope to get the FIXME done tonight.

Also of note, this patch adds a -extract-bbs option to bugpoint which can be used
to debug the block extractor.  (hint hint Misha :)

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.

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 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).

* 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

* 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

* 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.

about them.  Try to delete them if it doesn't affect the passes.

Chris Lattner de39f2bdac The big fix is this change:

+    if (!I->isExternal() && !Functions.count(I))

We were not actually deleting any functions from the module!
