688dd40912 Add preliminary support for "any" pointersize/endianness. This will need 
to change soon though.

8bc390da1b The JIT now passes the environment pointer to the main() function when it 
starts a program.  This allows the GNU env program to compile and JIT under
LLVM.

de8083df45 The CBE generates code which violates the TBAA rules of C, thus we must disable 
optimizations based on these rules.  :(

0709078b8d `execve_test' is not part of LLEE. 
llvm-svn: 7912
 2003-08-15 23:31:54 +00:00

6ad21447f8 A lot of changes were suggested by Chris. 
ExecveHandler.c:
* Use "" instead of <> for LLVM include files
* Use raw I/O, we don't need buffering
* Set errno = 0 before using open()
* strlen() doesn't count NULL terminator in its size
* Use memcmp() instead of strcmp()
* Return result of the real execve(), not 0
* Search for path to bytecode file if not absolute/relative path

SysUtils.c:
* Convert all comments to C-style
* Stop using `bool', use `unsigned' instead

SysUtils.h:
* Stop using `bool', use `unsigned' instead
* Updated comment to FindExecutable()

README.txt:
* Describe the goal of LLEE and an application

4f1ed9c65b Added code that ensures that we don't try to reduce an empty vector of basic 
blocks.

3c2462bb76 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

10e9e036c2 * Moved InputArgv out of anonymous scope to be extern'd in another file. 
* Added DEBUG() statements to print out parameters passed to executing programs
* Actually ADD parameters to a program running via the JIT (using vector<char*>)

a38f409401 Use a vector<char*> instead of char*[] so that we can add arbitrary number of 
parameters, such as command-line arguments that the executing program gets via
bugpoint.

6f05e9ea0c Revert change: default architecture is never set, it is guessed from input 
bytecode file. This means that LLC on X86 will compile to Sparc assembly given a
64-bit input bytecode file...

3564e354b3 * Disambiguate symbols before we start splitting module by functions 
* Moved DisambiguateGlobalSymbols() out of the ReduceMisCodegenFunctions class
* Added an assert to have a cleaner exit if `main' is not found in the module

397c1b8f48 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
