2010-03-31add new apis for getting/setting !dbg metadata on Chris Lattner
instructions. In addition to being a convenience, they are faster than the old apis, particularly when not going from an MDKindID like people should be doing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99982 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-30Added support for address spaces and added a isVolatile field to memcpy, ↵Mon P Wang
memmove, and memset, e.g., llvm.memcpy.i32(i8*, i8*, i32, i32) -> llvm.memcpy.p0i8.p0i8.i32(i8*, i8*, i32, i32, i1) A update of langref will occur in a subsequent checkin. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99928 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-30Introduce SpecificBumpPtrAllocator, a wrapper for BumpPtrAllocator which allowsBenjamin Kramer
only a single type of object to be allocated. Use it to make VNInfo destruction typesafe. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99919 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-30Rip out the 'is temporary' nonsense from the MCContext interface toChris Lattner
create symbols. It is extremely error prone and a source of a lot of the remaining integrated assembler bugs on x86-64. This fixes rdar://7807601. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99902 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-30Introduce another Reset() method in BumpPtrAllocator that calls a destructorTorok Edwin
on all objects it has allocated, if they are all of the same size and alignment. Use this to destruct all VNInfos allocated in LiveIntervalAnalysis (PR6653). valnos is not reliable for this purpose, as seen in r99400 (which still leaked, and sometimes caused double frees). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99881 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-29Re-add back in the slow way of determining of a clean-up should become aBill Wendling
catch-all. The "dominates" way won't catch all of the selectors which must be changed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99850 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-29A more general (and simpler!) implementation of r99671. It performs a similarBill Wendling
transform. I.e., if a clean-up eh.selector call dominates the invoke of an _Unwind_Resume_or_Rethrow, then we convert the eh.selector into a catch-all. This patch, however, uses the DominatorTree information, and doesn't go through the whole rigmarole of starting at the eh.exception call, finding the corresponding URoR and eh.selector calls, and trying to trace through any number of instruction types to get to them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99846 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-29Refactor code to push DILocation prcessing into DwarfDebug.cpp from ↵Devang Patel
AsmPrinter.cpp. This is same as r99772 (which was reverted) with just one meaningful difference where two source lines exchanged their positions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99816 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-28finally remove the immAllOnesV_bc/immAllZerosV_bc patternsChris Lattner
and those derived from them. These are obnoxious because they were written as: PatLeaf<(bitconvert). Not having an argument was foiling adding better type checking for operand count matching up with what was required (in this case, bitconvert always requires an operand!) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99759 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-28now that (parallel) is gone and a variety of bugs in targetsChris Lattner

2010-03-28add an optimized form of OPC_EmitMergeInputChains for the 1, 0 and Chris Lattner
1, 1 cases which are by-far the most frequent. This shrinks the X86 isel table from 77014 -> 74657 bytes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99740 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-27If a selector has a call to ".llvm.eh.catch.all.value" that we haven'tBill Wendling
converted, then use the initializer, since using the name itself won't work. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99692 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-26If we mark clean-ups as clean-ups, then it could break when inlining through anBill Wendling
'invoke' instruction. You will get a situation like this: bb: %ehptr = eh.exception() %sel = eh.selector(%ehptr, @per, 0); ... bb2: invoke _Unwind_Resume_or_Rethrow(%ehptr) %normal unwind to %lpad lpad: ... The unwinder will see the %sel call as a clean-up and, if it doesn't have a catch further up the call stack, it will skip running it. But there *is* another catch up the stack -- the catch for the %lpad. However, we can't see that. This is fixed in code-gen, where we detect this situation, and convert the "clean-up" selector call into a "catch-all" selector call. This gives us the correct semantics. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99671 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-25fix a valgrind error on copy-constructor-synthesis.cpp, which is caused whenChris Lattner
the custom insertion hook deletes the instruction, then we try to set dead flags on it. Neither the code that I added nor the code that was there before was safe. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99538 91177308-0d34-0410-b5e6-96231b3b80d8

currently. But add an assertion to verify it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99501 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-25Change tblgen to emit FOOISD opcode names as twoChris Lattner
bytes instead of one byte. This is important because we're running up to too many opcodes to fit in a byte and it is aggrevated by FIRST_TARGET_MEMORY_OPCODE making the numbering sparse. This just bites the bullet and bloats out the table. In practice, this increases the size of the x86 isel table from 74.5K to 76K. I think we'll cope :) This fixes rdar://7791648 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99494 91177308-0d34-0410-b5e6-96231b3b80d8
