* float comparison to double 'zero' constant can just be a float 'zero.'Jim Grosbach2011-09-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | InstCombine was incorrectly considering the conversion of the constant zero to be unsafe.

* Inlining often produces landingpad instructions with repeatedDuncan Sands2011-09-30
| | | | | | | | | | | | | | | catch or repeated filter clauses. Teach instcombine a bunch of tricks for simplifying landingpad clauses. Currently the code only recognizes the GNU C++ and Ada personality functions, but that doesn't stop it doing a bunch of "generic" transforms which are hopefully fine for any real-world personality function. If these "generic" transforms turn out not to be generic, they can always be conditioned on the personality function. Probably someone should add the ObjC++ personality function. I didn't as I don't know anything about it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@140852 91177308-0d34-0410-b5e6-96231b3b80d8

* Instead of crashing when MCAsmInfo is NULL, add an assert.Torok Edwin2011-09-30
| | | | | | | This helps with porting code from 2.9 to 3.0 as TargetSelect.h changed location, and if you include the old one by accident you will trigger this assert. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@140848 91177308-0d34-0410-b5e6-96231b3b80d8

* ARM fix encoding of VMOV.f32 and VMOV.f64 immediates.Jim Grosbach2011-09-30
| | | | | | | | | | | | | Encode the immediate into its 8-bit form as part of isel rather than later, which simplifies things for mapping the encoding bits, allows the removal of the custom disassembler decoding hook, makes the operand printer trivial, and prepares things more cleanly for handling these in the asm parser. rdar://10211428 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@140834 91177308-0d34-0410-b5e6-96231b3b80d8

* Order register classes topologically.Jakob Stoklund Olesen2011-09-30

| | | | | | | | This is used when we want to take the address of a machine basic block, but it's not associated with a BB in LLVM IR. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@140823 91177308-0d34-0410-b5e6-96231b3b80d8
