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.

2012-12-18Add to the disassembler C API an option to print the disassembledKevin Enderby
instructions in the assembly code variant if one exists. The intended use for this is so tools like lldb and darwin's otool(1) can be switched to print Intel-flavored disassembly. I discussed extensively this API with Jim Grosbach and we feel while it may not be fully general, in reality there is only one syntax for each assembly with the exception of X86 which has exactly two for historical reasons. rdar://10989182 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170477 91177308-0d34-0410-b5e6-96231b3b80d8
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

2012-12-18Disable ARM partial flag dependency optimization at -OzQuentin Colombet
To not over constrain the scheduler for ARM in thumb mode, some optimizations for code size reduction, specific to ARM thumb, are blocked when they add a dependency (like write after read dependency). Disables this check when code size is the priority, i.e., code is compiled with -Oz. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170462 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

2012-12-18Repair bundles that were broken by removing and reinserting the firstJakob Stoklund Olesen

2012-12-17Tighten up the erase/remove API for bundled instructions.Jakob Stoklund Olesen
Most code is oblivious to bundles and uses the MBB::iterator which only visits whole bundles. MBB::erase() operates on whole bundles at a time as before. MBB::remove() now refuses to remove bundled instructions. It is not safe to remove all instructions in a bundle without deleting them since there is no way of returning pointers to all the removed instructions. MBB::remove_instr() and MBB::erase_instr() will now update bundle flags correctly, lifting individual instructions out of bundles while leaving the remaining bundle intact. The MachineInstr convenience functions are updated so eraseFromParent() erases a whole bundle as before eraseFromBundle() erases a single instruction, leaving the rest of its bundle. removeFromParent() refuses to operate on bundled instructions, and removeFromBundle() lifts a single instruction out of its bundle. These functions will no longer accidentally split or coalesce bundles - bundle flags are updated to preserve the existing bundling, and explicit bundleWith* / unbundleFrom* functions should be used to change the instruction bundling. This API update is still a work in progress. I am going to update APIs first so they maintain bundle flags automatically when possible. Then I'll add stricter verification of the bundle flags. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170384 91177308-0d34-0410-b5e6-96231b3b80d8
