Nick Lewycky 3255d1d25f In DenseMapInfo<pair<T, U>> tombstone key, use the tombstone for T and U instead 
of the empty key for U. This shouldn't really matter because the tombstone key
for the pair was still distinct from every other key, but it is odd. Patch by
Michael Ilseman!

Bill Wendling 4c93488999 Make sure that the landingpad instruction takes a Constant* as the clause's value.

 2011-07-28 02:27:12 +00:00
Bill Wendling a8f04e3034 Add a couple of convenience functions: 
* InvokeInst: Get the landingpad instruction associated with this invoke.
* LandingPadInst: A method to reserve extra space for clauses.

Argyrios Kyrtzidis 348937de07 Add an optional 'bool makeAbsolute' in llvm::sys::fs::unique_file function. 
If true and 'model' parameter is not an absolute path, a temp directory will be prepended.
Make it true by default to match current behaviour.

Andrew Trick 3ca3f98c2c SCEV: Added a data structure for storing not-taken info per loop 
exit. Added an interfaces for querying either the loop's exact/max
backedge taken count or a specific loop exit's not-taken count.

 2011-07-23 01:40:15 +00:00
Benjamin Kramer 346f3a3b8c Turn the DenseSet in MCRegisterClass into a tblgenerated bit field. This should be faster and smaller. 
Goodbye static ctors and dtors!

 2011-07-23 00:47:49 +00:00
Benjamin Kramer 2754ca1e10 Give TargetRegisterClass a pointer to the MCRegisterClass and use it to access its data. 
This makes TargetRegisterClass slightly slower. Next step will be making contains faster.
Eventually TargetRegisterClass will be killed entirely.
