Gabor Greif 1a25ae88ff Fix buglet when the TST instruction directly uses the AND result.
I am unable to write a test for this case, help is solicited, though...
What I did is to tickle the code in the debugger and verify that we do the right thing.

Lang Hames 0937fc4b7f Added an additional PBQP problem builder which adds coalescing costs (both between pairs of virtuals, and between virtuals and physicals).

Gabor Greif adbbb93d3d Move the search for the appropriate AND instruction
into OptimizeCompareInstr.
This necessitates the passing of CmpValue around,
so widen the virtual functions to accomodate.

No functionality changes.

Chris Lattner a35499e2af a few more trivial updates. This fixes PerformInsertVectorEltInMemory to not
pass a completely incorrect SrcValue, which would result in a miscompile with
combiner-aa.

2010-09-21 06:43:24 +00:00
Chris Lattner 82fd06d3ce it's more elegant to put the "getConstantPool" and
"getFixedStack" on the MachinePointerInfo class.  While
this isn't the problem I'm setting out to solve, it is the
right way to eliminate PseudoSourceValue, so lets go with it.

Chris Lattner c3e05d6e50 update the X86 backend to use the MachinePointerInfo version of one
of the getLoad methods.  This fixes at least one bug where an incorrect
svoffset is passed in (a potential combiner-aa miscompile).

Marcin Swiderski c0ca7316bc Added:

- support for VarDecls in StmtPrinterHelper.

into non-segment-relative copies.

Chris Lattner 2510de2bea reimplement memcpy/memmove/memset lowering to use MachinePointerInfo
instead of srcvalue/offset pairs.  This corrects SV info for mem 
operations whose size is > 32-bits.

Chris Lattner bc419ba98f add overloads for SelectionDAG::getLoad, getStore, getTruncStore that take a
MachinePointerInfo.  Among other virtues, this doesn't silently  truncate the
svoffset to 32-bits.

Chris Lattner b5f4920979 force clients of MachineFunction::getMachineMemOperand to provide a
MachinePointerInfo, propagating the type out a level of API.  Remove
the old MachineFunction::getMachineMemOperand impl.

Ted Kremenek c2eb0116cc Check for null ObjCInterfaceDecls returned from getClassInterface() when generating USRs. While I have no test case for this (could not create one), this shows up in crash reports. Tentatively fixes <rdar://problem/8452791>.

Chris Lattner 187f653418 refactor the Value*/offset pair from MachineMemOperand out to a new
MachinePointerInfo struct, no functionality change.

This also adds an assert to MachineMemOperand::MachineMemOperand
that verifies that the Value* is either null or is an IR pointer type.

Sean Callanan fc55f5d1b0 Removed the hacky "#define this ___clang_this" handler
for C++ classes.  Replaced it with a less hacky approach:

 - If an expression is defined in the context of a
   method of class A, then that expression is wrapped as
   ___clang_class::___clang_expr(void*) { ... }
   instead of ___clang_expr(void*) { ... }.

 - ___clang_class is resolved as the type of the target
   of the "this" pointer in the method the expression
   is defined in.

 - When reporting the type of ___clang_class, a method
   with the signature ___clang_expr(void*) is added to
   that class, so that Clang doesn't complain about a
   method being defined without a corresponding
   declaration.

 - Whenever the expression gets called, "this" gets
   looked up, type-checked, and then passed in as the
   first argument.

This required the following changes:

 - The ABIs were changed to support passing of the "this"
   pointer as part of trivial calls.

 - ThreadPlanCallFunction and ClangFunction were changed
   to support passing of an optional "this" pointer.

 - ClangUserExpression was extended to perform the
   wrapping described above.

 - ClangASTSource was changed to revert the changes
   required by the hack.

 - ClangExpressionParser, IRForTarget, and
   ClangExpressionDeclMap were changed to handle
   different manglings of ___clang_expr flexibly.  This
   meant no longer searching for a function called
   ___clang_expr, but rather looking for a function whose
   name *contains* ___clang_expr.

 - ClangExpressionParser and ClangExpressionDeclMap now
   remember whether "this" is required, and know how to
   look it up as necessary.

A few inheritance bugs remain, and I'm trying to resolve
these.  But it is now possible to use "this" as well as
refer implicitly to member variables, when in the proper
context.

Johnny Chen 209cdbef64 Added the capability to source the configFile specified via the "-c" option in
order to customize the running of the test suite.  For the time being, the
supported customizations are:

o redirecting stdout and/or stderr
o specifying a list of compilers to build the test programs
o specifying a list of architectures to build the test programs for

Also checked into the examples/test directory some example files which
demonstrate the usage for the above customizations.

Douglas Gregor 7466127a4b When providing code completions for an argument in an Objective-C

Douglas Gregor f86e4da7ae Refactor code completion for expressions that occur as arguments in
Objective-C message sends. There is no functionality change here; this
is prep work for using the parameter types to help guide the
expression results when code-completing the argument.

llvm-svn: 114375
2010-09-20 23:34:21 +00:00
Douglas Gregor 5fb901deee Code completion has no reason to prefer values over types, especially
at the statement level or in Objective-C message receivers. Therefore,
just give types and declarations the same basic priority, and adjust
from there.

Evan Cheng f3e9a48584 Enable machine sinking critical edge splitting. e.g.
define double @foo(double %x, double %y, i1 %c) nounwind {
  %a = fdiv double %x, 3.2
  %z = select i1 %c, double %a, double %y
  ret double %z
}

Was:
_foo:
        divsd   LCPI0_0(%rip), %xmm0
        testb   $1, %dil
        jne     LBB0_2
        movaps  %xmm1, %xmm0
LBB0_2:
        ret

Now:
_foo:
        testb   $1, %dil
        je      LBB0_2
        divsd   LCPI0_0(%rip), %xmm0
        ret
LBB0_2:
        movaps  %xmm1, %xmm0
        ret

This avoids the divsd when early exit is taken.

Douglas Gregor 9dcf58a546 Tweak priorities for some types and macros:
- In Objective-C, we prefer BOOL to bool for historic reasons;
  slightly penalize "bool".
  - Treat Nil macro as a NULL pointer constant.
  - Treat YES, NO, true, and false macros as constants.
  - Treat the bool macro as a type.
