Anton Korobeynikov b9c91c265c Fixing PR990: http://llvm.org/PR990. 
This should unbreak csretcc on Linux & mingw targets. Several tests from
llvm-test should be also restored (fftbench, bigfib).

Chris Lattner 7275b02ea5 completely revert patrick's enhancement to bugpoint. Though it makes bugpoint 
speed up, it sometimes makes it crash on complex bc files, which isn't very nice.


With this, bugpoint can reduce the 176.gcc failure.

 2006-11-09 06:24:56 +00:00
Chris Lattner f1a1a7ae6f add a new bugpoint mode -llc-safe. This uses LLC for both halves of a 
miscompilation.  This is useful for working around GCC+CBE bugs or for handling
programs that CBE doesn't support (e.g. inline asm) when searching for
optimizer bugs.

Reid Spencer e73551303f Add a utility script to find a mis-optimization problem. This sometimes 
helps when bugpoint can't find the problem directly because it needs the
set of optimizations that cause the program to fail.

Evan Cheng 7120b9e9c7 Divide select methods into groups by SelectionDAG node opcodes (ISD::ADD, 
X86ISD::CMP, etc.) instead of SDNode names (add, x86cmp, etc). We now allow
multiple SDNodes to map to the same SelectionDAG node (e.g. store, indexed
store).
