CHECK-NOT.

the hopes that the two bitcasts will merge.

205b641954 Change tests from "opt %s" to "opt < %s" so that opt doesn't see the 
input filename so that opt doesn't print the input filename in the
output so that grep lines in the tests don't unintentionally match
strings in the input filename.

of using llvm-as, now that opt supports this.

1f08c79edc fix PR4848 an infinite loop when indexing down through a recursive gep 
and we get the original pointer type.  This doesn't mean that we're
at the first pointer being indexed.  Correct the predicate.

these instructions, no autoupgrade or backwards compatibility support is
provided.

5f6f8101d5 Split the Add, Sub, and Mul instruction opcodes into separate 
integer and floating-point opcodes, introducing
FAdd, FSub, and FMul.

For now, the AsmParser, BitcodeReader, and IRBuilder all preserve
backwards compatability, and the Core LLVM APIs preserve backwards
compatibility for IR producers. Most front-ends won't need to change
immediately.

This implements the first step of the plan outlined here:

d4bcc9011b Fix three bugs: 
1) evaluate [v]fcmp true/false with undefs to true or false instead
   of undef.
2) fix vector comparisons with undef to return a vector result instead 
   of i1
3) fix vector comparisons with evaluatable results to return vector
   true/false instead of i1 true/false (PR2529)

df17fa8ef9 For PR1319:

lines into the background. Also, clean up places where the same command
is run multiple times by using a temporary file.

56b310ae49 Make the llvm-runtest function much more amenable by eliminating all the 
global variables that needed to be passed in. This makes it possible to
add new global variables with only a couple changes (Makefile and llvm-dg.exp)
instead of touching every single dg.exp file.
