code that cross integer / floating point domains (e.g. generate pxor / pand for
logical ops on floating point value, movdqa to load / store floating point SSE
values). Given that, it's better to use movaps instead of movdqa and movups
instead of movdqu. They have the same latency but the "aps" variants are one
byte shorter.
If the domain crossing problem is a real performance issue, then we will have to
fix it with dynamic programming based isel.

Fix patterns so we isel the xorps, etc. for floating pt logical SSE ops. DAG combiner may fold away the (bit_convert (load)).

Change the keywords for the zext and sext parameter attributes to be 
zeroext and signext so they don't conflict with the keywords for the
instructions of the same name. This gets around the ambiguity.

We still need to do sematic analysis (and implement initializers), however this 
should complete the parsing & ast building for compound literals.

with hopefully correct code that pleases g++-4.2.

nowadays, unfortunately it's not so easy to get good
code here while still producing correct code in exotic
situations.

With this, the time to optimize 403.gcc is down to 15.1s.

llvm-svn: 40042

This results in a slight speedup for 403.gcc.

llvm-svn: 40040

llvm-svn: 40037

reduces the time to optimize 403.gcc from 17.6s to 16.4s.

second part dominates all the blocks dominated
by original basic block. And first part dominates
second part.

InOperandList. This gives one piece of important information: # of results
produced by an instruction.
An example of the change:
def ADD32rr  : I<0x01, MRMDestReg, (ops GR32:$dst, GR32:$src1, GR32:$src2),
                 "add{l} {$src2, $dst|$dst, $src2}",
                 [(set GR32:$dst, (add GR32:$src1, GR32:$src2))]>;
=>
def ADD32rr  : I<0x01, MRMDestReg, (outs GR32:$dst), (ins GR32:$src1, GR32:$src2),
                 "add{l} {$src2, $dst|$dst, $src2}",
                 [(set GR32:$dst, (add GR32:$src1, GR32:$src2))]>;

Work towards fixing crasher with compound literals...

Before this commit, we crashed in ParseBinOp...

[dylan:~/llvm/tools/clang] admin% ../../Debug/bin/clang -parse-ast-check compound_literal.c
SemaExpr.cpp:1298: failed assertion `(rhs != 0) && "ParseBinOp(): missing right expression"'

With this commit, we still crash in the newly added action ParseCompoundLiteral (which is progress:-)

[dylan:~/llvm/tools/clang] admin% ../../Debug/bin/clang -parse-ast-check compound_literal.c
SemaExpr.cpp:478: failed assertion `(Op != 0) && "ParseCompoundLiteral(): missing expression"'

The crash go away once the actions return AST nodes. I will do this in a separate commit.

for error recovery purposes.
