The TargetPassManager's default constructor wants to initialize the PassManager to 'null'. But it's illegal to bind a null reference to a null l-value. Make the ivar a pointer instead.

If the pass is *sure* that it thinks it knows what it's doing, then it may go ahead and specify that the landing pad can have its critical edge split. The loop unswitch pass is one of these passes. It will split the critical edges of all edges coming from a loop to a landing pad not within the loop. Doing so will retain important loop analysis information, such as loop simplify. ------------------------------------------------------------------------ git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_31@155833 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-18This reverts a long string of commits to the Hexagon backend. TheseChandler Carruth
commits have had several major issues pointed out in review, and those issues are not being addressed in a timely fashion. Furthermore, this was all committed leading up to the v3.1 branch, and we don't need piles of code with outstanding issues in the branch. It is possible that not all of these commits were necessary to revert to get us back to a green state, but I'm going to let the Hexagon maintainer sort that out. They can recommit, in order, after addressing the feedback. Reverted commits, with some notes: Primary commit r154616: HexagonPacketizer - There are lots of review comments here. This is the primary reason for reverting. In particular, it introduced large amount of warnings due to a bad construct in tablegen. - Follow-up commits that should be folded back into this when reposting: - r154622: CMake fixes - r154660: Fix numerous build warnings in release builds. - Please don't resubmit this until the three commits above are included, and the issues in review addressed. Primary commit r154695: Pass to replace transfer/copy ... - Reverted to minimize merge conflicts. I'm not aware of specific issues with this patch. Primary commit r154703: New Value Jump. - Primarily reverted due to merge conflicts. - Follow-up commits that should be folded back into this when reposting: - r154703: Remove iostream usage - r154758: Fix CMake builds - r154759: Fix build warnings in release builds - Please incorporate these fixes and and review feedback before resubmitting. Primary commit r154829: Hexagon V5 (floating point) support. - Primarily reverted due to merge conflicts. - Follow-up commits that should be folded back into this when reposting: - r154841: Remove unused variable (fixing build warnings) There are also accompanying Clang commits that will be reverted for consistency. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155047 91177308-0d34-0410-b5e6-96231b3b80d8

for the life of me remember why I wrote it this way, but I can't see any good reason for it now. This patch replaces the custom linked list with an ilist.

2012-04-16Implement GDB integration for source level debugging of code JITed usingPreston Gurd
the MCJIT execution engine. The GDB JIT debugging integration support works by registering a loaded object image with a pre-defined function that GDB will monitor if GDB is attached. GDB integration support is implemented for ELF only at this time. This integration requires GDB version 7.0 or newer.

2012-04-16Make it possible to indicate relaxed floating point requirements at the IR levelDuncan Sands
through the use of 'fpmath' metadata. Currently this only provides a 'fpaccuracy' value, which may be a number in ULPs or the keyword 'fast', however the intent is that this will be extended with additional information about NaN's, infinities etc later. No optimizations have been hooked up to this so far. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154822 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-14Rename "fpaccuracy" metadata to the more generic "fpmath". That's because I'mDuncan Sands
thinking of generalizing it to be able to specify other freedoms beyond accuracy (such as that NaN's don't have to be respected). I'd like the 3.1 release (the first one with this metadata) to have the more generic name already rather than having to auto-upgrade it in 3.2. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154744 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-11Cache the hash value of the operands in the MDNode.Benjamin Kramer
FoldingSet is implemented as a chained hash table. When there is a hash collision during insertion, which is common as we fill the table until a load factor of 2.0 is hit, we walk the chained elements, comparing every operand with the new element's operands. This can be very expensive if the MDNode has many operands. We sacrifice a word of space in MDNode to cache the full hash value, reducing compares on collision to a minimum. MDNode grows from 28 to 32 bytes + operands on x86. On x86_64 the new bits fit nicely into existing padding, not growing the struct at all. The actual speedup depends a lot on the test case and is typically between 1% and 2% for C++ code with clang -c -O0 -g. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154497 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-10The MDString class stored a StringRef to the string which was already in aBill Wendling
StringMap. This was redundant and unnecessarily bloated the MDString class. Because the MDString class is a "Value" and will never have a "name", and because the Name field in the Value class is a pointer to a StringMap entry, we repurpose the Name field for an MDString. It stores the StringMap entry in the Name field, and uses the normal methods to get the string (name) back.
