Douglas Gregor 9503c46a2e Don't import __va_list_tag or __builtin_va_list when merging 
llvm-svn: 96299
 2010-02-16 00:04:46 +00:00
Douglas Gregor b4964f7705 Cope with anonymous tags defined within declarators by structurally 
comparing their types under the assumption that they are equivalent,
rather than importing the types and then checking for compatibility. A
few minor tweaks here:
  - Teach structural matching to handle compatibility between
  function types with prototypes and those without prototypes.
  - Teach structural matching that an incomplete record decl is the
  same as any other record decl with the same name.
  - Keep track of pairs of declarations that we have already checked
  (but failed to find as structurally matching), so we don't emit
  diagnostics repeatedly.
  - When importing a typedef of an anonymous tag, be sure to link the
  imported tag type to its typedef.

With these changes, we survive a repeated import of <stdlib.h> and
<stdio.h>. Alas, the ASTNodeImporter is getting a little grotty.

Bob Wilson a945c64b5a Put repeated empty pattern into the AQI instruction class. 
We could almost use a multiclass for the signed/unsigned instructions, but
there are only 6 of them so I guess it's not worth it.

Anton Korobeynikov ec2ba08d16 It turns out that we emitted completely wrong common EH frame since the early beginning! The "z" CIE augmentation mark indicates that there is an extra word containing the size of augmentation section. However, even for frames w/o any augmentation data we emitted size uleb! (this is the case of "unwinding through C code"). Thus frame moves information was emitterd completely wrong.

A virtual register can be used before it is defined in the same MBB if the MBB
is part of a loop. Teach the implicit-def pass about this case.

Douglas Gregor 3996e249ed Reimplement the structural-equality checks used to determine whether 
two types in different AST contexts are equivalent. Rather than
transforming the type from one context into the other context, we
perform a deep structural comparison of the types. This change
addresses a serious problem with recursive data types like

  struct ListNode {
    int value;
    struct ListNode *Next;
  } xList;

Evan Cheng 5e73ff2e3a Split SelectionDAGISel::IsLegalAndProfitableToFold to 
IsLegalToFold and IsProfitableToFold. The generic version of the later simply checks whether the folding candidate has a single use.

This allows the target isel routines more flexibility in deciding whether folding makes sense. The specific case we are interested in is folding constant pool loads with multiple uses.
