a2e07a38bc Use movaps to load a v4f32 build_vector of all-constant values into a 
register instead of loading each element individually.

b9ad251288 Add initial support for non-local memory dependence analysis. 
NOTE: This has only been cursorily tested.  Expected improvements soon.

e8170a07f8 Heal EH handling stuff by emitting correct offsets to callee-saved registers. 
Pretty hackish, but code itself is dirty mess, so we won't make anything worse. :)

eb9f1b612c Add a GVN pass, using the value numbering code I developed for GVNPRE and the 
load elimination code from RedundantLoadElimination.

b9f23cc28b 1. Make sure we print the Function Value for parameter attribute errors 
2. Fold an if statement into the Assert1 macro call.

6286ca1d69 Add better verification of attributes on function types. It is not permitted 
to use sret or inreg on the function. It is equally illegal to use noreturn
or nounwind on a parameter; they only go with the function. This patch
enforces these rules.

5a29993695 The Ada f-e produces various auxiliary output files 
that cannot be suppressed and cannot be redirected:
they are dumped in the current working directory.
When running the testsuite this means that these
files do not end up in the Output directory.  The
best solution I could find is to change directory
into Output before running tests.

ec44ba07b5 For multipart tests, place the parts with no 
RUN line in Support.  Give up on sending output
to /dev/null - this cannot always be arranged.

ac8ccab48f Don't assume that only Uses can be kills. Defs are marked as kills initially 
when there are no uses. This fixes a dangling-pointer bug, where pointers to
deleted instructions were not removed from kills lists. More info here:

925762f19b Need -O1 or better to have these builtins lowered to 
llvm intrinsics in llvm-gcc-4.2.  This is because
get_pointer_alignment bails out: it relies on TER
to compute accurate alignment information.

e5c617b3a0 No longer referencing "shared memory" as this can confuse people. The memory is 
clearly shared between processors if these instructions are being used, no 
further specification of what type of memory is necessary.
