Owen Anderson 49f037ac29 Allow SmallPtrSet to hold pointers to const data.

Dan Gohman 4788552deb Re-apply 40504, but with a fix for the segfault it caused in oggenc: 
Make the alignedload and alignedstore patterns always require 16-byte
alignment. This way when they are used in the "Fs" instructions, in which
a vector instruction is used for a scalar purpose, they can still require
the full vector alignment. And add a regression test for this.

Duncan Sands 5d49bcdce0 It seems logical that InReg should be incompatible 
with StructReturn and ByVal, so make it so.

Duncan Sands 07c9066238 As the number of parameter attributes increases, 
Verifier::visitFunction is suffering a combinatorial
explosion due to the number of mutually incompatible
attributes.  This patch tidies the whole thing up
using attribute masks.  While there I fixed some
small bugs: (1) the ByVal attribute tests cast a
type to a pointer type, which can fail.  Yes, the
fact it is of a pointer type is checked before,
but a failing check does not cause the program
to exit, it continues on outputting further errors;
(2) Nothing was checking that an sret attribute is
on the first parameter; (3) nothing was checking that
a function for which isStructReturn() is true has a
parameter with the sret attribute and vice-versa (I
don't think it is possible for this to go wrong, but
it seems right to check it).

llvm-svn: 40077
 2007-07-20 00:27:56 +00:00
Evan Cheng 8fefeffb37 Because we promote SSE logical ops and loads to v2i64, we often end up generate 
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.

This patch fills the last necessary bits to enable exceptions

In fact, this patch adds necessary intrinsics (and their lowering) which
represent really weird target-specific gcc builtins used inside unwinder.
