Eli Friedman 55919a9ed7 Extend the undef ^ undef idiom once more. No testcase: I can't figure out how to actually trigger the codepath in question at the moment, but it might get exposed in the future.

Devang Patel eb1bb4e419 Until now all debug info MDNodes referred to a root MDNode, a compile unit. This simplified handling of these needs in dwarf writer. However, one side effect of this is that during link time optimization all these MDNodes are _not_ uniqued. In other words there will be N number of MDNodes describing "int", "char" and all other types, which would suddenly grow when each object file starts using libraries like STL. 
MDNodes graph structure such that compiler unit keeps track of important MDNodes and update dwarf writer to process mdnodes top-down instead of bottom up.

Eli Friedman 0793eb4c46 A bunch of misc fixes to SCCPSolver::ResolvedUndefsIn, including a fix to stop 
making random bad assumptions about instructions which are not explicitly listed.  

Includes fix for rdar://9956541, a version of "undef ^ undef should return
0 because it's easier than arguing with users".

Jim Grosbach 3e941aee69 ARM thumb assembly parsing for arithmetic flag setting instructions. 
Thumb one requires that many arithmetic instruction forms have an 'S'
suffix. For Thumb2, the whether the suffix is required or precluded depends
on whether the instruction is in an IT block. Use target parser predicates
to check for these sorts of context-sensitive constraints.

Bill Wendling 8ddfc09e7a Use the getFirstInsertionPt() method instead of getFirstNonPHI + an 'isa<>' 
check for a LandingPadInst.

llvm-svn: 137745
 2011-08-16 20:45:24 +00:00
Bill Wendling ee1c2d2437 Add getFirstInsertionPt() method. 
getFirstInsertionPt() returns an iterator to the first insertion point in a
basic block. This is after all PHIs and any other instruction which is required
to be at the top of the basic block (like LandingPadInst).

Greg Clayton 72da397a69 Fixed an issue where we could end up creating multiple 
C++ methods for a function depending on how the DWARF was 
created. Now we parse the class type from the definition,
and all methods that use DW_AT_specification or DW_AT_abstract_origin
attributes to point to the definition, now won't create
duplicate entries. This is in response to how clang++ creates
much different DWARF than gcc.

Bruno Cardoso Lopes 2e99f1b3aa Instead of always leaving the work to the generic legalizer when 
there is no support for native 256-bit shuffles, be more smart in some
cases, for example, when you can extract specific 128-bit parts and use
regular 128-bit shuffles for them. Example:

For this shuffle:
  shufflevector <4 x i64> %a, <4 x i64> %b, <4 x i32>
                <i32 1, i32 0, i32 7, i32 6>

This was expanded to:
  vextractf128  $1, %ymm1, %xmm2
  vpextrq $0, %xmm2, %rax
  vmovd %rax, %xmm1
  vpextrq $1, %xmm2, %rax
  vmovd %rax, %xmm2
  vpunpcklqdq %xmm1, %xmm2, %xmm1
  vpextrq $0, %xmm0, %rax
  vmovd %rax, %xmm2
  vpextrq $1, %xmm0, %rax
  vmovd %rax, %xmm0
  vpunpcklqdq %xmm2, %xmm0, %xmm0
  vinsertf128 $1, %xmm1, %ymm0, %ymm0
  ret

Now we get:
  vshufpd $1, %xmm0, %xmm0, %xmm0
  vextractf128  $1, %ymm1, %xmm1
  vshufpd $1, %xmm1, %xmm1, %xmm1
  vinsertf128 $1, %xmm1, %ymm0, %ymm0

Sean Callanan efe9a42379 Fixed a performance problem where functions were 
being searched for in too heavyweight a way.  Now,
when asking for the address of a function, the
expression parser just asks for a corresponding
data symbol.
