Evan Cheng de9e36a74e On Darwin, ams printer should output a second label before a jump table so the linker knows it's a new atom. But this is only needed if the jump table is put in a separate section from the function body.

Dan Gohman 8c9ac59455 Generalize LSR's OptimizeSMax to handle unsigned max tests as well
as signed max tests. Along with r73717, this helps CodeGen avoid
emitting code for a maximum operation for this class of loop.

Dan Gohman 4d3c3cfffd Recognize n != 0 ? n : 1 as umax(n, 1). Previously only ULT/UGT/ULE/UGE
comparisons were recognized for umax, but instcombine canonicalizes
unsigned comparisons with zero to this simpler form.

2009-06-18 18:26:15 +00:00
Owen Anderson 68f6598c69 Insert a SmartMutex templated class into the class hierarchy, which takes a template parameter specifying whether this mutex
should become a no-op when not running in multithreaded mode.  Make sys::Mutex a typedef of SmartMutex<false>, to preserve source compatibility.

Dan Gohman a0348809b6 Remove the code from IVUsers that attempted to handle
casted induction variables in cases where the cast
isn't foldable. It ended up being a pessimization in
many cases. This could be fixed, but it would require
a bunch of complicated code in IVUsers' clients. The
advantages of this approach aren't visible enough to
justify it at this time.

Dan Gohman 56bd02c55c Generalize the zext(trunc(t) & C) instcombine to work even with
C is not a low-bits mask, and add a similar instcombine for
zext((trunc(t) & C) ^ C).

double-checked locking pattern here.

Zhongxing Xu cea6578078 When casting region, if we do not create an element region, record the cast-to
type. 

When retrieving the region value, if we are going to create a symbol value, use
the cast-to type if possible.

Chris Lattner e7e659431c Fix a crash that can occur when a #pragma handler eats to the end of the
line, and when the pragma is at the end of a file.  In this case, the last
token consumed could pop the lexer, invalidating CurPPLexer.  Thanks to
Peter Thoman for pointing it out.

Evan Cheng 0e79603588 - Update register allocation hint after coalescing. This is done by the target since the hint is target dependent. This is important for ARM register pair hints.
- Register allocator should resolve the second part of the hint (register number) before passing it to the target since it knows virtual register to physical register mapping.
- More fixes to get ARM load / store double word working.

2009-06-18 01:33:24 +00:00
Ted Kremenek d93c6e3fd6 Remove more dependencies on GRStateRef. As a consequence, we can now
pretty-print a GRState object anywhere it is referenced (instead of
needing a GRStateRef of a GRStateManager handy).

Dale Johannesen 9d9acb065a It looks like nobody is working on PR 4158, so I'm
adding a check to catch this case at compile time
instead of quietly generating incorrect code.
That will at least let us identify CBE failures
that are not due to this problem.

Dan Gohman eddf77123a Teach ScalarEvolution how to recognize another xor(and(x, C), C) case.
If C is a single bit and the and gets analyzed as a truncate and
zero-extend, the xor can be represnted as an add.
