* [weak vtables] Remove a bunch of weak vtablesJuergen Ributzka2013-11-191-1/+4
| | | | | | | | | | | | This patch removes most of the trivial cases of weak vtables by pinning them to a single object file. The memory leaks in this version have been fixed.

* Revert r194865 and r194874.Alexey Samsonov2013-11-181-4/+1
| | | | | | | | | | | | | This change is incorrect. If you delete virtual destructor of both a base class and a subclass, then the following code: Base *foo = new Child(); delete foo; will not cause the destructor for members of Child class. As a result, I observe plently of memory leaks. Notable examples I investigated are: ObjectBuffer and ObjectBufferStream, AttributeImpl and StringSAttributeImpl. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194997 91177308-0d34-0410-b5e6-96231b3b80d8

* Simplify operand folding when rematerializing a load.Andrew Trick2013-11-121-1/+6
| | | | | | | | | | | | We already know how to fold a reload from a frameindex without analyzing the load instruction. Generalize this to handle any frameindex load. This streamlines the logic for rematerializing loads from stack arguments. As a side effect, it allows stackmaps to record a stack argument location without spilling it. Verified no effect on codegen for llvm test-suite. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194497 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix the recently added anyregcc convention to handle spilled operands.Andrew Trick2013-11-111-1/+10
| | | | | | | | | | | | Fixes <rdar://15432754> [JS] Assertion: "Folded a def to a non-store!" The primary purpose of anyregcc is to prevent a patchpoint's call arguments and return value from being spilled. They must be available in a register, although the calling convention does not pin the register. It's up to the front end to avoid using this convention for calls with more arguments than allocatable registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194428 91177308-0d34-0410-b5e6-96231b3b80d8
* [Stackmap] Add AnyReg calling convention support for patchpoint intrinsic.Juergen Ributzka2013-11-081-2/+8
| | | | | | | | | | | | | | The idea of the AnyReg Calling Convention is to provide the call arguments in registers, but not to force them to be placed in a paticular order into a specified set of registers. Instead it is up tp the register allocator to assign any register as it sees fit. The same applies to the return value (if applicable).

* Fix the ExecutionDepsFix pass to handle AVX instructions.Andrew Trick2013-10-141-14/+67
| | | | | | | | | | | | | | | | | | | | | | | | This pass is needed to break false dependencies. Without it, unlucky register assignment can result in wild (5x) swings in performance. This pass was trying to handle AVX but not getting it right. AVX doesn't have partial register defs, it has unused register reads in which the high bits of a source operand are copied into the unused bits of the dest. Fixing this requires conservative liveness analysis. This is awkard because the pass already has its own pseudo-liveness. However, proper liveness is expensive, and we would like to use a generic utility to compute it. The fix only invokes liveness on-demand. It is rare to detect a case that needs undef-read dependence breaking, but when it happens, it can be needed many times within a very large block. I think the existing heuristic which uses a register window of 16 is too conservative for loop-carried false dependencies. If the loop is a reduction. The out-of-order engine may be able to execute several loop iterations in parallel. However, I'll leave this tuning exercise for next time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192635 91177308-0d34-0410-b5e6-96231b3b80d8

* X86: Stop LEA64_32r doing unspeakable things to its arguments.Tim Northover2013-06-101-49/+163
| | | | | | | | | | | | Previously LEA64_32r went through virtually the entire backend thinking it was using 32-bit registers until its blissful illusions were cruelly snatched away by MCInstLower and 64-bit equivalents were substituted at the last minute. This patch makes it behave normally, and take 64-bit registers as sources all the way through. Previous uses (for 32-bit arithmetic) are accommodated via SUBREG_TO_REG instructions which make the types and classes agree properly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183693 91177308-0d34-0410-b5e6-96231b3b80d8

* X86: use sub-register sequences for MOV*r0 operationsTim Northover2013-05-301-50/+15
| | | | | | | | | | | | Instead of having a bunch of separate MOV8r0, MOV16r0, ... pseudo-instructions, it's better to use a single MOV32r0 (which will expand to "xorl %reg, %reg") and obtain other sizes with EXTRACT_SUBREG and SUBREG_TO_REG. The encoding is smaller and partial register updates can sometimes be avoided. Until recently, this sequence was a barrier to rematerialization though. That should now be fixed so it's an appropriate time to make the change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182928 91177308-0d34-0410-b5e6-96231b3b80d8
* X86: change zext moves to use sub-register infrastructure.Tim Northover2013-05-301-10/+1
| | | | | | | | | | | | 32-bit writes on amd64 zero out the high bits of the corresponding 64-bit register. LLVM makes use of this for zero-extension, but until now relied on custom MCLowering and other code to fixup instructions. Now we have proper handling of sub-registers, this can be done by creating SUBREG_TO_REG instructions at selection-time. Should be no change in functionality. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182921 91177308-0d34-0410-b5e6-96231b3b80d8

* X86: Bad peephole interaction between adc, MOV32r0David Majnemer2013-05-181-3/+18
| | | | | | | | | | | | | | | | | The peephole tries to reorder MOV32r0 instructions such that they are before the instruction that modifies EFLAGS. The problem is that the peephole does not consider the case where the instruction that modifies EFLAGS also depends on the previous state of EFLAGS. Instead, walk backwards until we find an instruction that has a def for EFLAGS but does not have a use. If we find such an instruction, insert the MOV32r0 before it. If it cannot find such an instruction, skip the optimization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182184 91177308-0d34-0410-b5e6-96231b3b80d8

This matches the directory structure of lib, and begins to correct a long standing point of file layout clutter in LLVM. There are still more header files to move here, but I wanted to handle them in separate commits to make tracking what files make sense at each layer easier. The only really questionable files here are the target intrinsic tablegen files. But that's a battle I'd rather not fight today.
