* Revert "llvm-cov: Added command-line option to change dir."Yuchen Wu2013-11-05
| | | | | | This reverts commit d8acf0078cf363252727acff00f85ae8074f95b3. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194040 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-cov: Added command-line option to change dir.Yuchen Wu2013-11-05
| | | | | | | This will allow for much easier testing when the input files are in a different folder from the test script. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194034 91177308-0d34-0410-b5e6-96231b3b80d8
* Support for reading run counts in llvm-cov.Yuchen Wu2013-11-05
| | | | | | | | | | | | This patch enables llvm-cov to correctly output the run count stored in the GCDA file. GCOVProfiling currently does not generate this information, so the GCDA run data had to be hacked on from a GCDA file generated by gcc. This is corrected by a subsequent patch. With the run and program data included, both llvm-cov and gcov produced the same output. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194033 91177308-0d34-0410-b5e6-96231b3b80d8
* Add a runtime unrolling parameter to the LoopUnroll pass constructorHal Finkel2013-11-05
| | | | | | | | | | | As with the other loop unrolling parameters (the unrolling threshold, partial unrolling, etc.) runtime unrolling can now also be controlled via the constructor. This will be necessary for moving non-trivial unrolling late in the pass manager (after loop vectorization). No functionality change intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194027 91177308-0d34-0410-b5e6-96231b3b80d8

* ARM: remove unnecessary state-tracking during frame lowering.Tim Northover2013-11-04
| | | | | | | | | | | | | | | | | | | | | ResolveFrameIndex had what appeared to be a very nasty hack for when the frame-index referred to a callee-saved register. In this case it "adjusted" the offset so that the address was correct if (and only if) the MachineInstr immediately followed the respective push. This "worked" for all forms of GPR & DPR but was only ever used to set the frame pointer itself, and once this was put in a more sensible location the entire state-tracking machinery it relied on became redundant. So I stripped it. The only wrinkle is that "add r7, sp, #0" might theoretically be slower (need an actual ALU slot) compared to "mov r7, sp" so I added a micro-optimisation that also makes emitARMRegUpdate and emitT2RegUpdate also work when NumBytes == 0. No test changes since there shouldn't be any functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194025 91177308-0d34-0410-b5e6-96231b3b80d8
* AArch64: use default asm operand printing when modifier inapplicableTim Northover2013-11-04
| | | | | | | | | | | | If an inline assembly operand has multiple constraints (e.g. "Ir" for immediate or register) and an operand modifier (E.g. "w" for "print register as wN") then we need to decide behaviour when the modifier doesn't apply to the constraint. Previousely produced some combination of an assertion failure and a fatal error. GCC's behaviour appears to be to ignore the modifier and print the operand in the default way. This patch should implement that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194024 91177308-0d34-0410-b5e6-96231b3b80d8

* Submit the basic port of the rest of ARM constant islands code to Mips. Reed Kotler2013-11-04
| | | | | | | | | | | | | | | | | | | Two test cases are added which reflect the next level of functionality: constants getting moved to water areas that are out of range from the initial placement at the end of the function and basic blocks being split to create water when none exists that can be used. There is a bunch of this code that is not complete and has been marked with IN_PROGRESS. I will finish cleaning this all up during the next week or two and submit the rest of the test cases. I have elminated some code for dealing with inline assembly because to me it unecessarily complicates things and some of the newer features of llvm like function attributies and builtin assembler give me better tools to solve the alignment issues created there. Also, for Mips16 I even have the option of not doing constant islands in the present of inline assembler if I chose. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194019 91177308-0d34-0410-b5e6-96231b3b80d8

* SLPVectorizer: When CSEing generated gathers only scan blocks containing them.Benjamin Kramer2013-11-03
| | | | | | | | | | | Instead of doing a RPO traversal of the whole function remember the blocks containing gathers (typically <= 2) and scan them in dominator-first order. The actual CSE is still quadratic, but I'm not confident that adding a scoped hash table here is worth it as we're only looking at the generated instructions and not arbitrary code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193956 91177308-0d34-0410-b5e6-96231b3b80d8

* LoopVectorizer: Perform redundancy elimination on induction variablesArnold Schwaighofer2013-11-01
| | | | | | | | | | | | | | | | | | | | When the loop vectorizer was part of the SCC inliner pass manager gvn would run after the loop vectorizer followed by instcombine. This way redundancy (multiple uses) were removed and instcombine could perform scalarization on the induction variables. Having moved the loop vectorizer to later we no longer run any form of redundancy elimination before we perform instcombine. This caused vectorized induction variables to survive that did not before. On a recent iMac this helps linpack back from 6000Mflops to 7000Mflops. This should also help lpbench and paq8p. I ran a Release (without Asserts) build over the test-suite and did not see any negative impact on compile time. radar://15339680 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193891 91177308-0d34-0410-b5e6-96231b3b80d8
* DebugInfo: Make pubnames header printing similar to unit header printingDavid Blaikie2013-11-01
| | | | | | | | | | | | | | | In a failed attempt to allow the gnu-public-names.ll test case to not hardcode the size of the unit that the pubnames section referred to I've at least managed to have unit headers and pubnames headers print out in a similar style. This failed to achieve the desired goal because the header in a unit specifies the length of the unit without the length element of the header whereas the length in the pubnames includes this element, so the numbers are off by 4 bytes. I don't know of any arithmetic powers in FileCheck so the test case can't simply say "CU_LENGTH + 4". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193872 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | linkonce_odr_auto_hide was in incomplete attempt to implement a way for the linker to hide symbols that are known to be available in every TU and whose addresses are not relevant for a particular DSO. It was redundant in that it all its uses are equivalent to linkonce_odr+unnamed_addr. Unlike those, it has never been connected to clang or llvm's optimizers, so it was effectively dead. Given that nothing produces it, this patch just nukes it (other than the llvm-c enum value). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193865 91177308-0d34-0410-b5e6-96231b3b80d8
