Chris Lattner e9dba0920b describe isStore and simplify the implementation of hasUnmodelledSideEffects. 
No functionality change. 

llvm-svn: 45651
 2008-01-06 05:43:21 +00:00
Chris Lattner 89c6566577 set the 'isstore' flag for instructions whose pattern is an 
intrinsic that writes to memory.

Chris Lattner e457fd1e9b remove some old hacky code that tried to infer whether a store 
occured in a pattern, but failed miserably.  The new code works for
any instruction that has a store in its pattern, including all the 
x86 mem op mem instructions.

The only target-independent code that uses this is branch folding,
so this won't change anything in practice.

llvm-svn: 45637
 2008-01-05 23:29:51 +00:00
Chris Lattner 7980bba549 now that computing CodegenDAGPatterns doesn't implicitly print stuff 
out, DAGISelEmitter can compute it in its ctor, which simplifies some code.

Now we can use CodegenDAGPatterns in other parts of tblgen that want access
to dag pattern info, woo!

Chris Lattner cc43e79bcd move Node Transformation printing from CodeGenDAGPatterns -> DAGISelEmitter. 
The only difference in output is that we now print them in alphabetical 
order instead of reverse alphabetical order.

Gordon Henriksen 9231958391 Refactoring the x86 and x86-64 calling convention implementations, 
unifying the copied algorithms and saving over 500 LOC. There should
be no functionality change, but please test on your favorite x86
target.

Bill Wendling be984cf10b Chris and Evan noticed that this check was compleatly fubared. I was 
checking that there was a from a global instead of a load from the stub
for a global, which is the one that's safe to hoist.

Consider this program:

volatile char G[100];
int B(char *F, int N) {
  for (; N > 0; --N)
    F[N] = G[N];
}

In static mode, we shouldn't be hoisting the load from G:

$ llc -relocation-model=static -o - a.bc -march=x86 -machine-licm

LBB1_1: # bb.preheader
        leal    -1(%eax), %edx
        testl   %edx, %edx
        movl    $1, %edx
        cmovns  %eax, %edx
        xorl    %esi, %esi
LBB1_2: # bb
        movb    _G(%eax), %bl
        movb    %bl, (%ecx,%eax)

Chris Lattner e0f0c4aa02 enable sinking and licm of loads from the argument area. I'd like to enable this 
for remat, but can't due to an RA bug.

Chris Lattner 69d7902cf1 factor some code better to avoid redundancy between 
isReallySideEffectFree and isReallyTriviallyReMaterializable.  Why is a load from
a global considered side-effect-free but not rematable?

Fariborz Jahanian 7b1b947ca1 twiks based on Chris's comment. No need to iterate thru a list of declarations 
in a foreach-statement which is illegal (but not yet caught) .

Chris Lattner db026d703b remove the (x-y) < 0 comparison xform, it miscompiles 
things that are not equality comparisons, for example:
   (2147479553+4096)-2147479553 < 0    !=   (2147479553+4096) < 2147479553

 2008-01-04 23:23:46 +00:00
Chris Lattner f735409e11 we already test for exact type matches early, so we don't have to do 
it explicitly for vectors.  This allows us to unnest some code.

Chris Lattner a52c2f2e3e simplify some of this code by removing the else/if chain and by 
stripping down to canonical types early.
