2012-12-25Rename LLVMContext diagnostic handler types and functions.Bob Wilson
These are now generally used for all diagnostics from the backend, not just for inline assembly, so this drops the "InlineAsm" from the names. No functional change. (I've left aliases for the old names but only for long enough to let me switch over clang to use the new ones.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171047 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-24Add LLVMContext::emitWarning methods and use them. <rdar://problem/12867368>Bob Wilson
When the backend is used from clang, it should produce proper diagnostics instead of just printing messages to errs(). Other clients may also want to register their own error handlers with the LLVMContext, and the same handler should work for warnings in the same way as the existing emitError methods. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171041 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-22Remove a special case that doesn't seem necessary any longer.Jakob Stoklund Olesen
Back when this exception was added, it was skipping a lot more code, but now it just looks like a premature optimization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170989 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-22Use getNumOperands() instead of Operands.size().Jakob Stoklund Olesen
The representation of the Operands array is going to change soon so it can be allocated from a BumpPtrAllocator. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170988 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-20Require the two-argument MI::addOperand(MF, MO) for dangling instructions.Jakob Stoklund Olesen
Instructions that are inserted in a basic block can still be decorated with addOperand(MO). Make the two-argument addOperand() function contain the actual implementation. This function will now always have a valid MF reference that it can use for memory allocation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170798 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-20Add an MF argument to MI::copyImplicitOps().Jakob Stoklund Olesen
This function is often used to decorate dangling instructions, so a context reference is required to allocate memory for the operands. Also add a corresponding MachineInstrBuilder method. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170797 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-20Use MachineInstrBuilder for PHI nodes in SelectionDAGISel.Jakob Stoklund Olesen
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170716 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-20Use MachineInstrBuilder in InstrEmitter.Jakob Stoklund Olesen
This is supposed to be a mechanical change with no functional effects. InstrEmitter can generate all types of MachineOperands which revealed that MachineInstrBuilder was missing a few methods, added by this patch. Besides providing a context pointer to MI::addOperand(), MachineInstrBuilder seems like a better fit for this code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170712 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-19Remove the explicit MachineInstrBuilder(MI) constructor.Jakob Stoklund Olesen
Use the version that also takes an MF reference instead. It would technically be possible to extract an MF reference from the MI as MI->getParent()->getParent(), but that would not work for MIs that are not inserted into any basic block. Given the reasonably small number of places this constructor was used at all, I preferred the compile time check to a run time assertion. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170588 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-19After reducing the size of an operation in the DAG we zero-extend the reducedNadav Rotem
bitwidth op back to the original size. If we reduce ANDs then this can cause an endless loop.

2012-12-18Use bidirectional bundle flags to simplify important functions.Jakob Stoklund Olesen
The bundle_iterator::operator++ function now doesn't need to dig out the basic block and check against end(). It can use the isBundledWithSucc() flag to find the last bundled instruction safely. Similarly, MachineInstr::isBundled() no longer needs to look at iterators etc. It only has to look at flags. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170473 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-18Verify bundle flag consistency when setting them.Jakob Stoklund Olesen
Now that the bundle flag aware APIs are all in place, it is possible to continuously verify the flag consistency. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170465 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-18Verify bundle flags for consistency in MachineVerifier.Jakob Stoklund Olesen
The new bidirectional bundle flags are redundant, so inadvertent bundle tearing can be detected in the machine code verifier. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170463 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-18Don't allow the automatically updated MI flags to be set directly.Jakob Stoklund Olesen
The bundle-related MI flags need to be kept in sync with the neighboring instructions. Don't allow the bulk flag-setting setFlags() function to change them. Also don't copy MI flags when cloning an instruction. The clone's bundle flags will be set when it is explicitly inserted into a bundle. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170459 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-18Tighten up the splice() API for bundled instructions.Jakob Stoklund Olesen
Remove the instr_iterator versions of the splice() functions. It doesn't seem useful to be able to splice sequences of instructions that don't consist of full bundles. The normal splice functions that take MBB::iterator arguments are not changed, and they can move whole bundles around without any problems. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170456 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-18Tighten the insert() API for bundled instructions.Jakob Stoklund Olesen
The normal insert() function takes an MBB::iterator position, and inserts a stand-alone MachineInstr as before. The insert() function that takes an MBB::instr_iterator position can insert instructions inside a bundle, and will now update the bundle flags correctly when that happens. When the insert position is between two bundles, it is unclear whether the instruction should be appended to the previous bundle, prepended to the next bundle, or stand on its own. The MBB::insert() function doesn't bundle the instruction in that case, use the MIBundleBuilder class for that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170437 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-18Check multiple register classes for inline asm tied registersHal Finkel
A register can be associated with several distinct register classes. For example, on PPC, the floating point registers are each associated with both F4RC (which holds f32) and F8RC (which holds f64). As a result, this code would fail when provided with a floating point register and an f64 operand because it would happen to find the register in the F4RC class first and return that. From the F4RC class, SDAG would extract f32 as the register type and then assert because of the invalid implied conversion between the f64 value and the f32 register. Instead, search all register classes. If a register class containing the the requested register has the requested type, then return that register class. Otherwise, as before, return the first register class found that contains the requested register. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170436 91177308-0d34-0410-b5e6-96231b3b80d8
