integers where there is unsigned overflow. Fix APFloat::toString so that it doesn't depend on the incorrect behavior in common cases (and computes the correct result in some rare cases).

2011-10-07Take all of the invoke basic blocks and make the dispatch basic block their newBill Wendling
successor. Remove the old landing pad from their successor list, because it's now the successor of the dispatch block. Now that the landing pad blocks are no longer the destination of invokes, we can mark them as normal basic blocks instead of landing pads. This more closely resembles what the CFG is actually doing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141436 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-07Take the code that was emitted for the llvm.eh.dispatch.setup intrinsic and emitBill Wendling
it with the new SjLj emitter stuff. This way there's no need to emit that kind-of-hacky intrinsic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141419 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-07Constrain both operands on MOVZX32_NOREXrr8.Jakob Stoklund Olesen
This instruction is explicitly encoded without an REX prefix, so both operands but be *_NOREX. Also add an assertion to copyPhysReg() that fires when the MOV8rr_NOREX constraints are not satisfied. This fixes a miscompilation in 20040709-2 in the gcc test suite. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141410 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-07Teach GVN to also propagate switch cases. For example, in this codeDuncan Sands
switch (n) { case 27: do_something(x); ... } the call do_something(x) will be replaced with do_something(27). In gcc-as-one-big-file this results in the removal of about 500 lines of bitcode (about 0.02%), so has about 1/10 of the effect of propagating branch conditions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141360 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-07Revert part of r141274. Only need to change encoding for xchg %eax, %eax in ↵Craig Topper
64-bit mode. This is because in 64-bit mode xchg %eax, %eax implies zeroing the upper 32-bits of RAX which makes it not a NOP. In 32-bit mode using NOP encoding is fine. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141353 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-06Generate the dispatch code for a 'thumb' function. This is very similar to theBill Wendling
