2009-01-06Fix a bug in ComputeLinearIndex computation handling multi-levelDan Gohman
aggregate types. Don't increment the current index after reaching the end of a struct, as it will already be pointing at one-past-the end. This fixes PR3288. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61828 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-01Fix PR3274: when promoting the condition of a BRCOND node,Duncan Sands
promote from i1 all the way up to the canonical SetCC type. In order to discover an appropriate type to use, pass MVT::Other to getSetCCResultType. In order to be able to do this, change getSetCCResultType to take a type as an argument, not a value (this is also more logical). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61542 91177308-0d34-0410-b5e6-96231b3b80d8

2008-12-23Clean up the atomic opcodes in SelectionDAG.Dan Gohman
This removes all the _8, _16, _32, and _64 opcodes and replaces each group with an unsuffixed opcode. The MemoryVT field of the AtomicSDNode is now used to carry the size information. In tablegen, the size-specific opcodes are replaced by size-independent opcodes that utilize the ability to compose them with predicates. This shrinks the per-opcode tables and makes the code that handles atomics much more concise. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61389 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-16We have decided not to support inline asm where an output operand with a ↵Evan Cheng
matching input operand with incompatible type (i.e. either one is a floating point and the other is an integer or the sizes of the types differ). SelectionDAGBuild will catch these and exit with an error. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61092 91177308-0d34-0410-b5e6-96231b3b80d8

2008-12-09Add sub/mul overflow intrinsics. This currently doesn't have aBill Wendling
target-independent way of determining overflow on multiplication. It's very tricky. Patch by Zoltan Varga! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60800 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-01There are no longer any places that require aDuncan Sands
MERGE_VALUES node with only one operand, so get rid of special code that only existed to handle that possibility. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@60349 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-24- Make lowering of "add with overflow" customizable by back-ends.Bill Wendling
- Mark "add with overflow" as having a custom lowering for X86. Give it a null lowering representation for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59971 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-21Rename "ADDO" to "SADDO" and "UADDO". The "UADDO" isn't equivalent to "ADDC"Bill Wendling
because the boolean it returns to indicate an overflow may not be treated like as a flag. It could be stored to memory, for instance. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59780 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-21Implement the sadd_with_overflow intrinsic. This is converted intoBill Wendling
"ISD::ADDO". ISD::ADDO is lowered into a target-independent form that does the addition and then checks if the result is less than one of the operands. (If it is, then there was an overflow.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59779 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-16Improved shuffle normalization to avoid using extract/build when weMon P Wang
can extract using different indexes for two vectors. Added a few tests for vector shuffles. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59399 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-10Added CONVERT_RNDSAT (conversion with rounding and saturation) SDNode toMon P Wang
support targets that support these conversions. Users should avoid using this node as the current targets don't generating code for it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@59001 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-10Added support for the following definition of shufflevector Mon P Wang

2008-11-07- Modify the stack protector algorithm so that the stack slot is allocated inBill Wendling
LLVM IR code and not in the selection DAG ISel. This is a cleaner solution. - Fix the heuristic for determining if protectors are necessary. The previous one wasn't checking the proper type size. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58824 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-06- Rename stackprotector_{prologue,epilogue} to stackprotector_{create,check}.Bill Wendling
- Get rid of "HasStackProtector" in MachineFrameInfo. - Modify intrinsics to tell which are doing what with memory. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58799 91177308-0d34-0410-b5e6-96231b3b80d8
2008-11-06Implement the stack protector stack accesses via intrinsics:Bill Wendling
- stackprotector_prologue creates a stack object and stores the guard there. - stackprotector_epilogue reads the stack guard from the stack position created by stackprotector_prologue. - The PrologEpilogInserter was changed to make sure that the stack guard is first on the stack frame. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58791 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-29Add sanity checking for BUILD_PAIR (I noticed theDuncan Sands
other day that PPC custom lowering could create a BUILD_PAIR of two f64 with a result type of... f64! - already fixed). Fix a place that triggers the sanity check. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58378 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-21Fix gcc.c-torture/compile/920520-1.c by inserting bitconvertsChris Lattner
for strange asm conditions earlier. In this case, we have a double being passed in an integer reg class. Convert to like sized integer register so that we allocate the right number for the class (two i32's for the f64 in this case). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57862 91177308-0d34-0410-b5e6-96231b3b80d8

2008-10-18Reapply r57699 with a fix to not crash on asms with multiple results. UnlikeChris Lattner
the previous patch this one actually passes make check. "Fix PR2356 on PowerPC: if we have an input and output that are tied together that have different sizes (e.g. i32 and i64) make sure to reserve registers for the bigger operand." git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57771 91177308-0d34-0410-b5e6-96231b3b80d8
2008-10-18Revert r57699. It's causing regressions inDan Gohman
