Devang Patel 9e30e1a3be Do not promote null values because it may be unsafe to do so.

Daniel Berlin 5d7136a1df Implement offline variable substitution in order to reduce memory
and time usage.
Fixup operator == to make this work, and add a resize method to DenseMap
so we can resize our hashtable once we know how big it should be.

code that creates the label too.

Dan Gohman 6002818999 Use the correct result value type instead of using getValueType(0)
in ExpandEXTRACT_VECTOR_ELT and SplitVectorOp. This fixes an abort
in the included testcase.

Ted Kremenek 962942f7a4 Added smart pointer class "IntrusiveSPtr" that handles reference
counted objects that maintain their own internal reference count.
This smart pointer implementation is compatible with LLVM-style
down-casting (see in llvm: include/llvm/Support/Casting.h).

Implemented "RefCounted", a base class that objects that wish to be
managed using IntrusiveSPtrs can subclass.

Reference counted objects are being targeted for use in path-sensitive
dataflow analyses where managing many live objects becomes difficult.

Chris Lattner 5b5484db63 claim that "st" is from the 80-bit register file. This causes x87-using inline
asm to die with:

ScheduleDAG.cpp:269: failed assertion `false && "Couldn't find the register class"'

instead of:
failed assertion `RegMap->getRegClass(VReg) == RC && "Register class of operand and regclass of use don't agree!"'

yay.

Chris Lattner d05e44e74e If we see an invalid #ifdef directive, enter a conditional compilation region
so that we don't emit an error on the #endif.  Suggestion by Neil.

Owen Anderson 15efb43db7 Factor the calculation details for PostDomTree out of PostDominators.cpp and
into a separate header file.

Next step: merging PostDominatorCalculation.h with DominatorCalculation.h.

Owen Anderson da853a400f Move DFSPass back down into DominatorTree. I need to figure out what the difference is between it
and the PostDomTree version first.

2007-09-23 21:32:55 +00:00
Owen Anderson 84c357fc26 Factor the dominator tree calculation details out into DominatorCalculation.h. This
change is not useful in and of itself, but it lays the groundwork for combining
the dominator and postdominator implementations.

Also, factor a few methods that are common to DominatorTree and PostDominatorTree
into DominatorTreeBase.  Again, this will make merging the two calculation methods
simpler in the future.

Dale Johannesen e36c400255 Fix PR 1681. When X86 target uses +sse -sse2,
keep f32 in SSE registers and f64 in x87.  This
is effectively a new codegen mode.
Change addLegalFPImmediate to permit float and
double variants to do different things.
Adjust callers.

Chris Lattner 322abe3573 Use the APFloat routines to evaluate FP immediates as
integer constant expressions.  The only questionable
thing is that we now reject:

void foo() {
  switch (1) {
  case (int)1.0e10000:
    ;
  }
}

with:

t.c:5:13: error: case label does not reduce to an integer constant
  case (int)1.0e10000:
       ~~~~~^~~~~~~~~

GCC accepts this, emitting the pedwarn:
t.c:5: warning: floating constant exceeds range of 'double'

Fariborz Jahanian 7e5d533098 This patch adds to new things to clang:
1. Handles saving and checking on protocols used in an @interface declaration
2. Checks and saves class's super class.
3. Adds semantic check to category declarations.
