Chris Lattner 7e89a616e6 Don't print spurious linking warnings about methods that are never used.
Cleanup ExprTypeConvert a bit.

Vikram S. Adve 596721384b Modified graph construction to use one pass to find all defs.
Avoids having to handle some special cases that cause complex interactions
with instr. selection.

Vikram S. Adve d3be60db35 Make gcc generate assembly files (%.ll) until Chris has a stable
version of his gccas.  Plus another dumb bug fix (the bug, not the fix).

2001-11-05 00:35:56 +00:00
Vikram S. Adve 4d04e00072 Delete rule to disassemble %.bc -- need to make it effective only when
%.ll is not a pre-existing file.

llvm-svn: 1121
2001-11-04 20:21:12 +00:00
Vikram S. Adve ea5d1f5db8 Fixed instruction information for RDCCR and WRCCR.
Fixed selection to create a TmpInstruction for each integer CC register
(since it is an implicit side-effect, unlike FP CC registers which are
explicit operands).

Ruchira Sasanka 471babe2d2 Added an assertion since it seems like AdjList returns an errornous size in method
IGNode::pushOnStack().

Chris Lattner ec83fc091e Add new cleanup pass:
//  1. PHI nodes with multiple entries for the same predecessor.  GCC sometimes
//     generates code that looks like this:
//
//  bb7:  br bool %cond1004, label %bb8, label %bb8
//  bb8: %reg119 = phi uint [ 0, %bb7 ], [ 1, %bb7 ]
//
//     which is completely illegal LLVM code.  To compensate for this, we insert
//     an extra basic block, and convert the code to look like this:
//
//  bb7: br bool %cond1004, label %bbX, label %bb8
//  bbX: br label bb8
//  bb8: %reg119 = phi uint [ 0, %bbX ], [ 1, %bb7 ]
//

Chris Lattner 784c623efb * Export method to merge identically named methods
* Add code to fix PHI nodes that are missing arguments.  These PHI nodes can
  be generated by GCC if there is an uninitialized variable flowing into a merge
  point.  For example:

int foo(int y) {
  int X;
  if (y) X = 1;
  return X;
}

Chris Lattner 629d7a7849 Changes to compile the TSP benchmark successfully. Favor warning instead of assertion failures.

Chris Lattner 1f3947c1d1 Add code to link method together with the same name if one is vararg and the other isn't.
This resolves definitions like this:
   %list * "foo"(...)
   %list * "foo"(int)

together which can often occur because C programmers don't put prototypes in like they should.  GRR

Chris Lattner 9bc6b190cc * Add comments for peepholes
* Implement new peephole:
     // Peephole optimize the following instructions:
     // %t1 = cast {<...>} * %StructPtr to <ty> *
     //
     // Into: %t2 = getelementptr {<...>} * %StructPtr, <0, 0, 0, ...>
     //       %t1 = cast <eltype> * %t1 to <ty> *

  This peephole eliminated 9 evil casts in the health benchmark, and
  completely turned the addList method around.  :)
