* Support X86_64_GOTLoad relocations in RuntimeDyldMachO by treating them theLang Hames2013-08-151-4/+4
| | | | | | | | | | | | | | | | | | same way as X86_64_GOT relocations. The 'Load' part of GOTLoad is just an optimization hint for the linker anyway, and can be safely ignored. This patch also fixes some minor issues with the relocations introduced while processing an X86_64_GOT[Load]: the addend for the GOT entry should always be zero, and the addend for the replacement relocation at the original offset should be the same as the addend of the relocation being replaced. I haven't come up with a good way of testing this yet, but I'm working on it. This fixes <rdar://problem/14651564>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188499 91177308-0d34-0410-b5e6-96231b3b80d8

* make arm-use-movt available for all ARMRenato Golin2013-08-151-3/+3
| | | | | | | | | | | | | Before this patch this flag is IOS specific, but is also useful for bare project like bootloaders / kernels etc, since movw / movt prevents simple relocation. Therefore make this flag more commonly available. note: this patch depends on a similiar rename in clang Patch by Jeroen Hofstee. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188487 91177308-0d34-0410-b5e6-96231b3b80d8
* make arm-reserve-r9 available for all ARMRenato Golin2013-08-151-2/+3
| | | | | | | | | | | r9 is defined as a platform-specific register in the ARM EABI. It can be reserved for a special purpose or be used as a general purpose register. Add support for reserving r9 for all ARM, while leaving the IOS usage unchanged.

* DataFlowSanitizer: Add a debugging feature to help us track nonzero labels.Peter Collingbourne2013-08-152-2/+71
| | | | | | | | | | | | | | | | | | Summary: When the -dfsan-debug-nonzero-labels parameter is supplied, the code is instrumented such that when a call parameter, return value or load produces a nonzero label, the function __dfsan_nonzero_label is called. The idea is that a debugger breakpoint can be set on this function in a nominally label-free program to help identify any bugs in the instrumentation pass causing labels to be introduced.

* This fixes three issues related to Thumb literal loads:Mihai Popa2013-08-155-13/+25
| | | | | | | | | | 1. The offset range for Thumb1 PC relative loads is [0..1020] and not [-1024..1020] 2. Thumb2 PC relative loads may define the PC, so the restriction placed on target register is removed 3. Removes unneeded alias between "ldr.n" and t1LDRpci.

* Auto-compute live intervals on demand.Mark Lacey2013-08-149-101/+145
| | | | | | | | | | | | | | | When new virtual registers are created during splitting/spilling, defer creation of the live interval until we need to use the live interval. Along with the recent commits to notify LiveRangeEdit when new virtual registers are created, this makes it possible for functions like TargetInstrInfo::loadRegFromStackSlot() and TargetInstrInfo::storeRegToStackSlot() to create multiple virtual registers as part of the process of generating loads/stores for different register classes, and then have the live intervals for those new registers computed when they are needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188437 91177308-0d34-0410-b5e6-96231b3b80d8
* Add the MachineInstrSpan class.Mark Lacey2013-08-141-0/+25
| | | | | | | | | | | | | | | MachineInstrSpan is initialized with a MachineBasicBlock::iterator, and is intended to track which instructions are inserted before/after that instruction from the time the MachineInstrSpan is created. It provides a begin()/end() interface to walk the range of instructions inserted around the initial instruction (including that initial instruction). It also provides a getInitial() interface to return the initial iterator. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188436 91177308-0d34-0410-b5e6-96231b3b80d8
* Notify LiveRangeEdit of new virtual registers.Mark Lacey2013-08-144-5/+50
| | | | | | | | | Add a delegate class to MachineRegisterInfo with a single virtual function, MRI_NoteNewVirtualRegister(). Update LiveRangeEdit to inherit from this delegate class and override the definition of the callback with an implementation that tracks the newly created virtual registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188435 91177308-0d34-0410-b5e6-96231b3b80d8
* Track new virtual registers by register number.Mark Lacey2013-08-1411-74/+83
| | | | | | | | | | Track new virtual registers by register number, rather than by the live interval created for them. This is the first step in separating the creation of new virtual registers and new live intervals. Eventually live intervals will be created and populated on demand after the virtual registers have been created and used in instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188434 91177308-0d34-0410-b5e6-96231b3b80d8

* DataFlowSanitizer: greylist is now ABI list.Peter Collingbourne2013-08-144-99/+334
| | | | | | | | | | | | | | | | | | | | | | | | | This replaces the old incomplete greylist functionality with an ABI list, which can provide more detailed information about the ABI and semantics of specific functions. The pass treats every function in the "uninstrumented" category in the ABI list file as conforming to the "native" (i.e. unsanitized) ABI. Unless the ABI list contains additional categories for those functions, a call to one of those functions will produce a warning message, as the labelling behaviour of the function is unknown. The other supported categories are "functional", "discard" and "custom". - "discard" -- This function does not write to (user-accessible) memory, and its return value is unlabelled. - "functional" -- This function does not write to (user-accessible) memory, and the label of its return value is the union of the label of its arguments. - "custom" -- Instead of calling the function, a custom wrapper __dfsw_F is called, where F is the name of the function. This function may wrap the original function or provide its own implementation.
