2012-04-16Flip the new block-placement pass to be on by default.Chandler Carruth
This is mostly to test the waters. I'd like to get results from FNT build bots and other bots running on non-x86 platforms. This feature has been pretty heavily tested over the last few months by me, and it fixes several of the execution time regressions caused by the inlining work by preventing inlining decisions from radically impacting block layout. I've seen very large improvements in yacr2 and ackermann benchmarks, along with the expected noise across all of the benchmark suite whenever code layout changes. I've analyzed all of the regressions and fixed them, or found them to be impossible to fix. See my email to llvmdev for more details. I'd like for this to be in 3.1 as it complements the inliner changes, but if any failures are showing up or anyone has concerns, it is just a flag flip and so can be easily turned off. I'm switching it on tonight to try and get at least one run through various folks' performance suites in case SPEC or something else has serious issues with it. I'll watch bots and revert if anything shows up. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154816 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-11Fix bugs in lowering of FCOPYSIGN nodes.Akira Hatanaka
- FCOPYSIGN nodes that have operands of different types were not handled. - Different code was generated depending on the endianness of the target. Additionally, code is added that emits INS and EXT instructions, if they are supported by target (they are R2 instructions). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@154540 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-25Continue cleanup of LIT, getting rid of the remaining artifacts from dejagnuEli Bendersky
* Removed test/lib/llvm.exp - it is no longer needed * Deleted the dg.exp reading code from test/lit.cfg. There are no dg.exp files left in the test suite so this code is no longer required. test/lit.cfg is now much shorter and clearer * Removed a lot of duplicate code in lit.local.cfg files that need access to the root configuration, by adding a "root" attribute to the TestingConfig object. This attribute is dynamically computed to provide the same information as was previously provided by the custom getRoot functions. * Documented the config.root attribute in docs/CommandGuide/lit.pod git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153408 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-08Remove the no longer existent psp triple from a test.Benjamin Kramer
The test fell back to the C backend, making it useless and it started to fail on configurations that don't build the C backend. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152342 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-01Fix bugs which were introduced when support for base+index floating point loadsAkira Hatanaka
and stores was added. - SelectAddr should return false if Parent is an unaligned f32 load or store. - Only aligned load and store nodes should be matched to select reg+imm floating point instructions. - MIPS does not have support for f64 unaligned load or store instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151843 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-24Add an option to use a virtual register as the global base register instead ofAkira Hatanaka
reserving a physical register ($gp or $28) for that purpose. This will completely eliminate loads that restore the value of $gp after every function call, if the register allocator assigns a callee-saved register, or eliminate unnecessary loads if it assigns a temporary register. example: .cpload $25 // set $gp. ... .cprestore 16 // store $gp to stack slot 16($sp). ... jalr $25 // function call. clobbers $gp. lw $gp, 16($sp) // not emitted if callee-saved reg is chosen. ... lw $2, 4($gp) ... jalr $25 // function call. lw $gp, 16($sp) // not emitted if $gp is not live after this instruction. ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151402 91177308-0d34-0410-b5e6-96231b3b80d8

run with LIT now and now Dejagnu. dg.exp is no longer needed. Patch reviewed by Daniel Dunbar. It will be followed by additional cleanup patches. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150664 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-03Add a new MachineJumpTableInfo entry type, EK_GPRel64BlockAddress, which isAkira Hatanaka
needed to emit a 64-bit gp-relative relocation entry. Make changes necessary for emitting jump tables which have entries with directive .gpdword. This patch does not implement the parts needed for direct object emission or JIT. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149668 91177308-0d34-0410-b5e6-96231b3b80d8

2012-01-25Modify MipsFrameLowering::emitPrologue and emitEpilogue.Akira Hatanaka
- Use MipsAnalyzeImmediate to expand immediates that do not fit in 16-bit. - Change the types of variables so that they are sufficiently large to handle 64-bit pointers. - Emit instructions to set register $28 in a function prologue after instructions which store callee-saved registers have been emitted. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148917 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-19Remove the restriction on the first operand of the add node in SelectAddr.Akira Hatanaka
This change reduces the number of instructions generated. For example, (load (add (sub $n0, $n1), (MipsLo got(s)))) results in the following sequence of instructions: 1. sub $n2, $n0, $n1 2. lw got(s)($n2) Previously, three instructions were needed. 1. sub $n2, $n0, $n1 2. addiu $n3, $n2, got(s) 3. lw 0($n3) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146888 91177308-0d34-0410-b5e6-96231b3b80d8

2011-12-13Relocation against a symbol, instead of against section. We had some extremeAkira Hatanaka
test cases where there were a lot of relocations applied relative to a large rodata section. Gas would create a symbol for each of these whereas we would be relative to the beginning of the rodata section. This change mimics what gas does.
