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.

2004-04-02 06:32:45 +00:00
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. :) :)

2004-03-16 01:51:54 +00:00
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...

Chris Lattner eddfe437c7 Now that tailduplication does not bork SSA form, run mem2reg earlier in gccas.
This tremendously improves the code generated by the LLVM optimizer, primarily
by making the inliner more aggressive.  For example, it improves the stepanov
benchmark from 55.56 mega-additions/sec to 98.04 Ma/s.  It also improves the
oopack/iterator benchmark from 338.3MFLOPS/s to 1103.4MFLOPS/s.  Less noteworthy,
it improves oopack/matrix from 573 -> 641 MFLOPS/s.
