Chris Lattner 6544289af3 move some functions, add a FIXME, use PrintPICBaseSymbol to print the
picbase instead of inlining it.

David Greene 30048bdb63 This increases the maximum for MVT::LAST_VALUETYPE
This change doubles the allowable value for MVT::LAST_VALUETYPE. It does
this by doing several things.

1. Introduces MVT::MAX_ALLOWED_LAST_VALUETYPE which in this change has a
value of 64.  This value contains the current maximum for the
MVT::LAST_VALUETYPE.

2. Instead of checking "MVT::LAST_VALUETYPE <= 32", all of those uses
now become "MVT::LAST_VALUETYPE <= MVT::MAX_ALLOWED_LAST_VALUETYPE"

3. Changes the dimension of the ValueTypeActions from 2 elements to four
elements and adds comments ahead of the declaration indicating the it is
"(MVT::MAX_ALLOWED_LAST_VALUETYPE/32) * 2".  This at least lets us find
what is affected if and when MVT::MAX_ALLOWED_LAST_VALUETYPE gets
changed.

4. Adds initializers for the new elements of ValueTypeActions.

This does NOT add any types in MVT. That would be done separately.

This doubles the size of ValueTypeActions from 64 bits to 128 bits and
gives us the freedom to add more types for AVX.

Dan Gohman f19aeec3f5 Extend ScalarEvolution's multiple-exit support to compute exact
trip counts in more cases.

Generalize ScalarEvolution's isLoopGuardedByCond code to recognize
And and Or conditions, splitting the code out into an
isNecessaryCond helper function so that it can evaluate Ands and Ors
recursively, and make SCEVExpander be much more aggressive about
hoisting instructions out of loops.

test/CodeGen/X86/pr3495.ll has an additional instruction now, but
it appears to be due to an arbitrary register allocation difference.

operand is implicit, indicated by DS:EDI.  This causes the table-generation code

Dale Johannesen c99c9d3f01 This test only works on ppc32 if some optimization is done before
generating LLVM IR; it is correct in the code as written
to use 8-byte-aligned operations to copy Key in bar.  Formerly
the gcc inliner was run, now it isn't.  I don't think it's
possible to preserve this as a pure FE test.  Adding -O2 lets
the llvm optimizers get rid of the 8-byte-aligned stores, at least.

Dale Johannesen 736ffeeab4 See test. Judging from PR 1278, at the time the test was committed, the
generated code was apparently doing stores directly into the return value
aggregate; now, it's doing a copy from a compiler-generated static object.
That object is initialized using [4 x i8] which breaks the test.  I believe
this change preserves the original point of the test.

Of course it would be better for the code to do stores directly into the
return aggregate, but that is not what happens at -O0; the llvm optimizers
seem to do that on x86 but not on ppc32, possibly because of the explicit
padding (which is unavoidable).  I think it must have been being done by
a gcc optimizer pass before.

Chris Lattner 7d2b049404 change TLS_ADDR lowering to lower to a real mem operand, instead of matching as
a global with that gets printed with the :mem modifier.  All operands to lea's 
should be handled with the lea32mem operand kind, and this allows the TLS stuff
to do this.  There are several better ways to do this, but I went for the minimal
change since I can't really test this (beyond make check).

This also makes the use of EBX explicit in the operand list in the 32-bit, 
instead of implicit in the instruction.
