Chris Lattner 5ce8303950 generate code for node and pattern predicates. Note that this won't 
build if enabled, it will fail with constness issues. I'll resolve 
these next.

Anders Carlsson 77904f1d5b Emit vbase offsets. 
llvm-svn: 96329

Anders Carlsson dc2dba306c More work on the new layout code. 
llvm-svn: 96328
 2010-02-16 04:49:44 +00:00
John McCall 6ce747220a When emitting complete destructors for classes with virtual bases, compute 
the offset to the virtual bases statically inside of relying on the virtual
base offsets in the object's vtable(s).  This is both more efficient and
sound against the destructor's manipulation of the vtables.

Also extract a few helper routines.

Oh and we seem to pass all tests with an optimized clang now.

John McCall 1e3715acc3 White-list comma expressions with the literal 0 as their RHS against

Sanjiv Gupta adcee844ea The code section for an ISR has a specific address. 
Currently, whether a function is ISR or not is encoded in the section attribute for that function.

Sanjiv Gupta ecd2600c52 Re-applying 96173. Looks like finally I got the test case right.

arguments of asprintf (<rdar://problem/6657191>).

Dale Johannesen d7eb693643 Handle DBG_VALUE mixed with labels when doing PHI 
elimination.  Before a DBG_VALUE could affect codegen.
The solution here is imperfect and not final.

Rafael Espindola af25cf825c Drop support for the InReg attribute on the ppc backend. This was used by 
llvm-gcc but has been replaced with pad argument which don't need any
special backend support.

Dan Gohman 521efe68ab Split the main for-each-use loop again, this time for GenerateTruncates, 
as it also peeks at which registers are being used by other uses. This
makes LSR less sensitive to use-list order.

Dale Johannesen d37e7b5bc5 Reapply 96294; now that I've gotten around to looking 
at older buildbot messages, I see the failure predates
this patch.

Dale Johannesen ae87fc43a7 Something broke. Hard to believe it was this patch 
but it's harder to believe it's the other candidate,
so reverting.  Temporarily I hope.

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.
