2010-02-25This is a patch to the assembler frontend to detect when aligning a textKevin Enderby
section with TextAlignFillValue and calls EmitCodeAlignment() instead of calling EmitValueToAlignment(). This allows x86 assembly code to be aligned with optimal nops. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97158 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-25Remove code which assumes it knows how vectors are stored in memory.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97141 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-25Revert r97064. Duncan pointed out that bitcasts are defined inDan Gohman
terms of store and load, which means bitcasting between scalar integer and vector has endian-specific results, which undermines this whole approach. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97137 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-25Make the side-numbering of instructions used by metadata (which is needed toNick Lewycky
keep track of instructions that return void) per-function. This fixes PR5278. This breaks backwards compatibility with the metadata format. That's okay because we haven't released the metadata bitcode yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97132 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-25Make LoopSimplify change conditional branches in loop exiting blocksDan Gohman
which branch on undef to branch on a boolean constant for the edge exiting the loop. This helps ScalarEvolution compute trip counts for loops. Teach ScalarEvolution to recognize single-value PHIs, when safe, and ForgetSymbolicName to forget such single-value PHI nodes as apprpriate in ForgetSymbolicName. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97126 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-25Dump the presence of attached metadata even if we don't know what it is. ThisNick Lewycky
format is not parsable, even if the module is legal. To get parsable output, dump the module instead of the function or smaller, since metadata kind are attached to the module (not the context). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97124 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-25Truncate from i64 to i32 is "free" on x86-32, because it involves Dan Gohman
just discarding one of the registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97100 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-25Large stack frame patch for the CellSPU: handle stack frames that exceed 8176Scott Michel
(511*16) bytes register displacement (D-form). NOTE: This is a potential headache, given the SPU's local core limitations, allowing the software developer to commit stack overrun suicide unknowingly. Also, large SPU stack frames will cause code size explosion. But, one presumes that the software developer knows what they're doing...

2010-02-25MC'ize padding when padding the ULEB128 value.Bill Wendling
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97087 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-24LLVM puts padding bytes in the __gcc_except_tab section after theBill Wendling
GCC_except_table label but before the Lexception, which the FDE references. This causes problems as the FDE does not point to the start of an LSDA chunk. Use an unnormalized uleb128 for the call-site table length that includes the padding. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97078 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-24Create a stack frame on ARM whenJakob Stoklund Olesen
- Function uses all scratch registers AND - Function does not use any callee saved registers AND - Stack size is too big to address with immediate offsets. In this case a register must be scavenged to calculate the address of a stack object, and the scavenger needs a spare register or emergency spill slot. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97071 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-24Check for comparisons of +/- zero when optimizing less-than-or-equal andBob Wilson
greater-than-or-equal SELECT_CCs to NEON vmin/vmax instructions. This is only allowed when UnsafeFPMath is set or when at least one of the operands is known to be nonzero. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97065 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-24Make getTypeSizeInBits work correctly for array types; it should returnDan Gohman
the number of value bits, not the number of bits of allocation for in-memory storage. Make getTypeStoreSize and getTypeAllocSize work consistently for arrays and vectors. Fix several places in CodeGen which compute offsets into in-memory vectors to use TargetData information. This fixes PR1784. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97064 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-24When forming SSE min and max nodes for UGE and ULE comparisons, it'sDan Gohman
necessary to swap the operands to handle NaN and negative zero properly. Also, reintroduce logic for checking for NaN conditions when forming SSE min and max instructions, fixed to take into consideration NaNs and negative zeros. This allows forming min and max instructions in more cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97025 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-24Change the scheduler from adding nodes in allnodes orderChris Lattner
to adding them in a determinstic order (bottom up from the root) based on the structure of the graph itself. This updates tests for some random changes, interesting bits: CodeGen/Blackfin/promote-logic.ll no longer crashes. I have no idea why, but that's good right? CodeGen/X86/2009-07-16-LoadFoldingBug.ll also fails, but now compiles to have one fewer constant pool entry, making the expected load that was being folded disappear. Since it is an unreduced mass of gnast, I just removed it. This fixes PR6370 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97023 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97011 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-24Add an argument to PHITranslateValue to specify the DominatorTree. If thisBob Wilson
argument is non-null, pass it along to PHITranslateSubExpr so that it can prefer using existing values that dominate the PredBB, instead of just blindly picking the first equivalent value that it finds on a uselist. Also when the DominatorTree is specified, have PHITranslateValue filter out any result that does not dominate the PredBB. This is basically just refactoring the check that used to be in GetAvailablePHITranslatedSubExpr and also in GVN. Despite my initial expectations, this change does not affect the results of GVN for any testcases that I could find, but it should help compile time. Before this change, if PHITranslateSubExpr picked a value that does not dominate, PHITranslateWithInsertion would then insert a new value, which GVN would later determine to be redundant and would replace. By picking a good value to begin with, we save GVN the extra work of inserting and then replacing a new value. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97010 91177308-0d34-0410-b5e6-96231b3b80d8
