Ted Kremenek aedb7434c8 Add clang-cc option "-analyzer-experimental-checks" to enable experimental path-sensitive checks. The idea is to separate "barely working" or "skunkworks" checks from ones that should always run. Later we need more fine-grain checker control.

David Greene 2f4c37425b Fix a bootstrap failure. 
Provide special isLoadFromStackSlotPostFE and isStoreToStackSlotPostFE
interfaces to explicitly request checking for post-frame ptr elimination
operands.  This uses a heuristic so it isn't reliable for correctness.

Douglas Gregor 9533e2803f We need the definition of NamedDecl in DeclContextInternals.h, since Clang is type-checking the template definition more thoroughly

David Greene 70fdd57dc1 Add hasLoadFromStackSlot and hasStoreToStackSlot to return whether a 
machine instruction loads or stores from/to a stack slot.  Unlike
isLoadFromStackSlot and isStoreFromStackSlot, the instruction may be
something other than a pure load/store (e.g. it may be an arithmetic
operation with a memory operand).  This helps AsmPrinter determine when
to print a spill/reload comment.

This is only a hint since we may not be able to figure this out in all
cases.  As such, it should not be relied upon for correctness.

Implement for X86.  Return false by default for other architectures.

Bill Wendling e3ae25b3d8 If there's more than one function operand to a call instruction, be conservative 
and don't assume that the call doesn't throw. It would be nice if there were a
way to determine which is the callee and which is a parameter. In practice, the
architecture we care about normally only have one operand for a call instruction
(x86 and arm).

llvm-svn: 87023
 2009-11-12 20:51:53 +00:00
David Greene 1fbe054450 Add a bool flag to StackObjects telling whether they reference spill 
slots.  The AsmPrinter will use this information to determine whether to
print a spill/reload comment.

Remove default argument values.  It's too easy to pass a wrong argument
value when multiple arguments have default values.  Make everything
explicit to trap bugs early.

Update all targets to adhere to the new interfaces..

Mike Stump 2cefe38365 Fix the offset calculations for non-virtual bases with overrides. 
Refine the VTT entries for virtual bases to refer to the complete
object's vtable instead of constructor vtables.

Refine the AddressPoint calculations for VTT entries for virtual bases.

StringsEqualNoCase (from StringExtras.h) to it.

David Greene 81eb42d8ca Make FixedStackPseudoSourceValue a first-class PseudoSourceValue by 
making it visible to clients and adding LLVM-style cast capability.
This will be used by AsmPrinter to determine when to emit spill comments
for an instruction.

llvm-svn: 87019
 2009-11-12 20:25:07 +00:00
David Greene 815863f157 Add AsmPrinter comment flags to machine instructions so that AsmPrinter 
can emit extra information in comments.

Fariborz Jahanian eb80c98a72 Fix a code gen bug in i386-apple-darwin (objc fragile abi), sending 
message to 'super'. Fixes radar 7205866.

llvm-svn: 87017
 2009-11-12 20:14:24 +00:00
David Greene 33935767b9 Add comment flags so AsmPrinter can output additional information when 
emitting comments.  These flags carry semantic information not otherwise
easily derivable from the IR text.

Douglas Gregor 49ba3cabdd Recognize (and check) pointer-to-member template arguments that are 
non-type template parameters or constants of pointer-to-member
type. Once checked, be sure to retain those pointer-to-member
constants as expressions if they are dependent, or as declarations if
they are not dependent.

Douglas Gregor 4e948ce769 When instantiating a reference to a non-type template parameter of pointer to 
member type (e.g., T Class::*Member), build a pointer-to-member
constant expression. Previously, we we just building a simple
declaration reference expression, which meant that the expression was
not treated as a pointer to member.

Jim Grosbach 5d57714e6c Update TB[BH] layout optimization. Add support for moving the target block 
to directly follow the jump table. Move the layout changes to prior to any
constant island handling.

Douglas Gregor 6051c8d344 Give CanQual<T> an implicit conversion to bool, so that it can be used 
in "if" statements like:

  if (CanQual<ReferenceType> RefType = T.getAs<ReferenceType>())

Thanks to Clang for pointing out this mistake :)
