Sanjiv Gupta 428d490332 Before trying to introduce/eliminate cast/ext/trunc to make indices type as 
pointer type, make sure that the pointer size is a valid sequential index type.

Duncan Sands f2e7133d34 Now that BUILD_VECTOR operands are allowed to be 
bigger than the vector element type, turn checking
of the operand type back on again, appropriately
adjusted.

Duncan Sands 3da896d861 Remove the SimpleTy enumerated type field from the MVT 
value type union: this field was causing problems for
some compilers on 64 bit systems, presumably because
SimpleTy is 32 bits wide while the other fields are
64 bits wide.

Duncan Sands e4ff21ba4b Don't try to make BUILD_VECTOR operands have the same 
type as the vector element type: allow them to be of
a wider integer type than the element type all the way
through the system, and not just as far as LegalizeDAG.
This should be safe because it used to be this way
(the old type legalizer would produce such nodes), so
backends should be able to handle it.  In fact only
targets which have legal vector types with an illegal
promoted element type will ever see this (eg: <4 x i16>
on ppc).  This fixes a regression with the new type
legalizer (vec_splat.ll).  Also, treat SCALAR_TO_VECTOR
the same as BUILD_VECTOR.  After all, it is just a
special case of BUILD_VECTOR.

Nick Lewycky 13590cb204 Generalize to support more ARM types. 
Configure was not actually regenerated, but the change last time only touched
this one line, so I'm being lazy and cheating by fixing it manually.

 2009-04-18 18:11:26 +00:00
Dan Gohman 31efa3098f Add a ScalarEvolution::getCouldNotCompute() function, and use it 
instead of allocating and leaking new SCEVCouldNotCompute objects.

Dale Johannesen 2f6263fea3 Adjust XFAIL syntax, maybe that will help. The other 
way worked for me...

Dale Johannesen e34fb6b5ce patch 69408 breaks this by removing the opportunity 
for the optimization it's testing to kick in (although
it improves the code, getting rid of all spills).
I don't understand the optimization well enough to
rescue the test, so XFAILing.

Dale Johannesen ad968ee286 Inline asm's were still introducing bogus dependencies;

Rafael Espindola 355fe12c82 For general dynamic TLS access we must use 
leaq	foo@TLSGD(%rip), %rdi

as part of the instruction sequence. Using a register other than %rdi and then
copying it to %rdi is not valid.

Dan Gohman d2d6fd806c Don't create ConstantInts with pointer type. This fixes a

Evan Cheng b96a1082a9 Teach spiller to unfold instructions which modref spill slot when a scratch 
register is available and when it's profitable.

e.g.
     xorq  %r12<kill>, %r13
     addq  %rax, -184(%rbp)
     addq  %r13, -184(%rbp)
==>
     xorq  %r12<kill>, %r13
     movq  -184(%rbp), %r12
     addq  %rax, %r12
     addq  %r13, %r12
     movq  %r12, -184(%rbp)

Two more instructions, but fewer memory accesses. It can also open up
opportunities for more optimizations.

Dan Gohman 09dbb0b5e0 MOV8rr_NOREX is a "Move" instruction. This doesn't currently 
matter, because this instruction isn't generated until after
things that care.

llvm-svn: 69336
 2009-04-17 00:45:17 +00:00
Dan Gohman 74835ce1cb Don't use MOV8rr_NOREX on x86-32. It doesn't actually hurt anything at 
present, but it's inconsistent.

Bob Wilson b8c370a8b5 Fix PR3994: LLVMMatchType arguments do not refer to absolute return value 
and argument positions but only to the overloaded intrinsic parameters.
Keep a separate list of these overloaded parameters in CodeGenTarget.cpp
so they can be resolved easily.  Remove assertions from IntrinsicEmitter.cpp:
they were harmless but confusing, and the assertions elsewhere in TableGen
will catch any incorrect values.

Chris Lattner 11ceb38df0 make sure to unlock keymgr if the JIT is created and destroyed, all 
locks must be matched with unlocks.  Also, use calloc to allocate the
block so that it is properly zero'd.  Thanks to Nick Kledzik for
tracking this down.
