2011-10-10Fix a regression from r138445. If we're loading from the frame/base pointerChad Rosier
the tADDrSPi instruction can't be used. Make sure we're updating the opcode to tADDi3 in all cases. rdar://10254707 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141523 91177308-0d34-0410-b5e6-96231b3b80d8

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
2011-10-07Thread the chain through the eh.sjlj.setjmp intrinsic, like it's documented toBill Wendling
do. This will be useful later on with the new SJLJ stuff. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141416 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-07Improve ARM assembly parser diagnostic for unexpected tokens.Jim Grosbach
Consider: mov r8, r11 fred Previously, we issued the not very informative: x.s:6:1: error: unexpected token in argument list ^ Now we generate: x.s:5:14: error: unexpected token in argument list mov r8, r11 fred ^ git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141380 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-06Generate the dispatch code for a 'thumb' function. This is very similar to theBill Wendling
others. They take the call site value. Determine if it's a proper value. And then jumps to the correct call site via a jump table. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141341 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-06Fix the check for nested IT instructions in the disassembler. We need to ↵Owen Anderson
perform the check before adding the Thumb predicate, which pops on entry off the ITBlock queue. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141339 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-06* Set the low bit of the return address when we are in thumb mode.Bill Wendling
* Some code cleanup. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141317 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-06Add the MBBs before inserting the instructions. Doing it afterwards could leadBill Wendling
to an infinite loop because of the def-use chains. Also use a frame load instead of store for the LD instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141263 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-05Remove a check from ARM shifted operand isel helper methods, which were blockingCameron Zwarich
merging an lsl #2 that has multiple uses on A9. This shift is free, so there is no problem merging it in multiple places. Other unprofitable shifts will not be merged. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141247 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-05There is no point in setting out-parameters for a ComplexPattern function whenCameron Zwarich
it returns false, at least as far as I could tell by reading the code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141172 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-05Checkpoint for SJLJ EH code.Bill Wendling
This is a first pass at generating the jump table for the sjlj dispatch. It currently generates something plausible, but hasn't been tested thoroughly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141140 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-04Teach the MC to output code/data region marker labels in MachO and ELF ↵Owen Anderson
modes. These are used by disassemblers to provide better disassembly, particularly on targets like ARM Thumb that like to intermingle data in the TEXT segment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141135 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-04Adding back support for printing operands symbolically to ARM's new disassemblerKevin Enderby
using llvm's public 'C' disassembler API now including annotations. Hooked this up to Darwin's otool(1) so it can again print things like branch targets for example this: blx _puts instead of this: blx #-36 and includes support for annotations for branches to symbol stubs like: bl 0x40 @ symbol stub for: _puts and annotations for pc relative loads like this: ldr r3, #8 @ literal pool for: Hello, world! Also again can print the expression encoded in the Mach-O relocation entries for things like this: movt r0, :upper16:((_foo-_bar)+1234) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141129 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-03Check-pointing the new SjLj EH lowering.Bill Wendling
This code will replace the version in ARMAsmPrinter.cpp. It creates a new machine basic block, which is the dispatch for the return from a longjmp call. It then shoves the address of that machine basic block into the correct place in the function context so that the EH runtime will jump to it directly instead of having to go through a compare-and-jump-to-the-dispatch bit. This should be more efficient in the common case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141031 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-03Thumb2 ADD/SUB can take SP as a destination register.Jim Grosbach
It's documented as a separate instruction to line up with the Thumb1 encodings, for which it really is a distinct instruction encoding. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141020 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-01Some more refactoring.Bill Wendling
* Add a couple of Create methods to the ARMConstantPoolConstant class, * Add its own version of getExistingMachineCPValue, and * Modify hasSameValue to return false if the object isn't an ARMConstantPoolConstant. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@140935 91177308-0d34-0410-b5e6-96231b3b80d8
