Nick Lewycky [Sun, 5 Feb 2012 19:56:38 +0000 (19:56 +0000)]
Teach GlobalOpt to handle atomic accesses to globals.

 * Most of the transforms come through intact by having each transformed load or
store copy the ordering and synchronization scope of the original.
 * The transform that turns a global only accessed in main() into an alloca
(since main is non-recursive) with a store of the initial value uses an
unordered store, since it's guaranteed to be the first thing to happen in main.
(Threads may have started before main (!) but they can't have the address of a
function local before the point in the entry block we insert our code.)
 * The heap-SRoA transforms are disabled in the face of atomic operations. This
can probably be improved; it seems odd to have atomic accesses to an alloca
that doesn't have its address taken.

AnalyzeGlobal keeps track of the strongest ordering found in any use of the
global. This is more information than we need right now, but it's cheap to
compute and likely to be useful.

Fix a leak!

Andy, in a previous commit you made this into an ImmutablePass so that you could
add it to the PassManager, then in the next commit you left it a Pass but
removed the code that added it to the PM. If you do add it to the PM then the PM
should take care of deleting it, but it's also true that nothing in codegen
needs this object to exist after it's done its work here. It's not clear to me
which design you want; this should likely either cease to be a Pass or be added
to the PM where other parts of CodeGen will request it.

12 years agoAdd pseudo-registers for pairs, triples, and quads of D registers.
Jakob Stoklund Olesen [Thu, 2 Feb 2012 22:45:32 +0000 (22:45 +0000)]
Add pseudo-registers for pairs, triples, and quads of D registers.

NEON loads and stores accept single and double spaced pairs, triples,
and quads of D registers.  This patch adds new register classes to
accurately model those constraints:

  Dn, Dn+1    Dn, Dn+2
  ----------------------
  DPair       DPairSpc
  DTriple     DTripleSpc
  DQuad       DQuadSpc

Also extend the existing QQ and QQQQ register classes to contains all Q
pairs and quads instead of just the aligned ones.

These new register classes will make it possible to accurately model
constraints on NEON loads and stores, and we can get rid of all the NEON
pseudo-instructions.  The late scheduler will be able to accurately
model instruction dependencies from the explicit operands.

This more than doubles the number of ARM registers, but the backend
passes are quite good at handling this. The llc -O0 compile time only
regresses by 1.5%.  Future work on register mask operands will recover
this regression.
