Merge from mainline.2009-08-31T06:12:11ZTanya Lattnertonic@nondot.org2009-08-31T06:12:11Zurn:sha1:72e4d4b370b44fc02f4bd3370b99393ba8052170
Fix non-determinism in DAGISel emitter.
- This manifested as non-determinism in the .inc output in rare cases (when two
distinct patterns ended up being equivalent, which is rather rare). That
meant the pattern matching was non-deterministic, which could eventually mean
the code generator selected different instructions based on the arch.
- It's probably worth making the DAGISel ensure a total ordering (or force the
user to), but the simple fix here is to totally order the Record* maps based
on a unique ID.
- PR4672, PR4711.

Extend the instruction itinerary model to include the ability to indicate the def and use cycle for each operand. This additional information is optional, so existing itineraries do not need to be changed.2009-08-17T16:02:57ZDavid Goodwindavid_goodwin@apple.com2009-08-17T16:02:57Zurn:sha1:fac8541dd40e01aa2b52962516f9ae67c99720cc

the MinPad argument to PadToColumn only really makes sense to be 1,2009-08-17T15:48:08ZChris Lattnersabre@nondot.org2009-08-17T15:48:08Zurn:sha1:8f4b1ec02bbc72161a9bd9777a2996dae439c81e
just remove the argument and replace it with 1.

Add a new "SDTCisVec" SDTypeConstraint. This complements the vAny type.2009-08-12T22:30:59ZBob Wilsonbob.wilson@apple.com2009-08-12T22:30:59Zurn:sha1:36e3e668be0c4914660575d7cea800b0d51a4116
There have been a few times where I've wanted this but ended up leaving the
operand type unconstrained. It is easy to add this now and should help
catch errors in the future.

Enhance the InstrStage object to enable the specification of an Itinerary with overlapping stages. The default is to maintain the current behavior that the "next" stage immediately follows the previous one.2009-08-12T18:31:53ZDavid Goodwindavid_goodwin@apple.com2009-08-12T18:31:53Zurn:sha1:1a8f36e3ce5b9c230781b66600c81536128abfb5

Add contexts to some of the MVT APIs. No functionality change yet, just the infrastructure work needed to get the contexts to where they need to be first.2009-08-12T00:36:31ZOwen Andersonresistor@mac.com2009-08-12T00:36:31Zurn:sha1:23b9b19b1a5a00faa9fce0788155c7dbfd00bfb1

llvm-mc/AsmParser: Match hard coded registers (e.g. 'shldl %cl, %eax, %eax')2009-08-11T23:23:44ZDaniel Dunbardaniel@zuster.org2009-08-11T23:23:44Zurn:sha1:1095f2ae261d231a63d329b0ebbf6eaf566ff429
We now match all of 403.gcc (as emitted by clang). :)
