2011-09-30Inlining often produces landingpad instructions with repeatedDuncan Sands
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

2011-09-30ARM fix encoding of VMOV.f32 and VMOV.f64 immediates.Jim Grosbach
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

2011-09-29Rewrite MachineInstr::addOperand() to avoid NumImplicitOps.Jakob Stoklund Olesen
The function needs to scan the implicit operands anyway, so no performance is won by caching the number of implicit operands added to an instruction. This also fixes a bug when adding operands after an implicit operand has been added manually. The NumImplicitOps count wasn't kept up to date. MachineInstr::addOperand() will now consistently place all explicit operands before all the implicit operands, regardless of the order they are added. It is possible to change an MI opcode and add additional explicit operands. They will be inserted before any existing implicit operands. The only exception is inline asm instructions where operands are never reordered. This is because of a hack that marks explicit clobber regs on inline asm as <implicit-def> to please the fast register allocator. This hack can go away when InstrEmitter and FastIsel can add exact <dead> flags to physreg defs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@140744 91177308-0d34-0410-b5e6-96231b3b80d8
