2013-04-24Use pointers to iterate over symbols.Rafael Espindola
While here, don't report a dummy symbol for relocations that don't have symbols. We used to says such relocations were for the first defined symbol, but now we return end_symbols(). The llvm-readobj output change agrees with otool. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180214 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-24Don't produce an empty llvm.compiler.used in LTO.Rafael Espindola
LTO was always creating an empty llvm.compiler.used. With this patch we now first check if there is anything to be added first. Unfortunately, there is no good way to test libLTO in isolation as it needs gold or ld64, but there are bots doing LTO builds that found this problem. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180202 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-24Don't forward declare environ on WindowsReid Kleckner
That seems to interact poorly with the environ and _environ macros defined in MSVC's <stdlib.h>. Also remove the incorrect comment about _NSGetEnviron(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180200 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-24LoopVectorizer: Change variable name Stride to ConsecutiveStrideArnold Schwaighofer
This makes it easier to read the code. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180197 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-24LoopVectorize: Scalarize padded typesArnold Schwaighofer
This patch disables memory-instruction vectorization for types that need padding bytes, e.g., x86_fp80 has 10 bytes store size with 6 bytes padding in darwin on x86_64. Because the load/store vectorization is performed by the bit casting to a packed vector, which has incompatible memory layout due to the lack of padding bytes, the present vectorizer produces inconsistent result for memory instructions of those types. This patch checks an equality of the AllocSize of a scalar type and allocated size for each vector element, to ensure that there is no padding bytes and the array can be read/written using vector operations. Patch by Daisuke Takahashi! Fixes PR15758. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180196 91177308-0d34-0410-b5e6-96231b3b80d8

This should bring the ppc bots back. I will try to write a test that would have found the problem on a little endian system too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180194 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-24MI Sched: eliminate local vreg copies.Andrew Trick
For now, we just reschedule instructions that use the copied vregs and let regalloc elliminate it. I would really like to eliminate the copies on-the-fly during scheduling, but we need a complete implementation of repairIntervalsInRange() first. The general strategy is for the register coalescer to eliminate as many global copies as possible and shrink live ranges to be extended-basic-block local. The coalescer should not have to worry about resolving local copies (e.g. it shouldn't attemp to reorder instructions). The scheduler is a much better place to deal with local interference. The coalescer side of this equation needs work. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180193 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-24Register Coalescing: add a flag to disable rescheduling.Andrew Trick
When MachineScheduler is enabled, this functionality can be removed. Until then, provide a way to disable it for test cases and designing MachineScheduler heuristics. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180192 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-24Use a pointer as the relocation iterator.Rafael Espindola
Since the relocation iterator walks only the relocations in one section, we can just use a pointer and avoid fetching information about the section at every reference. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180189 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-23Machine model: Generate table entries for super-resources.Andrew Trick
Super-resources and resource groups are two ways of expressing overlapping sets of processor resources. Now we generate table entries the same way for both so the scheduler never needs to explicitly check for super-resources. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180162 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-23Simplify yaml2obj a bit.Rafael Espindola
The COFFParser now contains only a COFFYAML::Object and the string table (which is recomputed, not serialized). The structs in COFFParser now all begin with a Header field with what is actually on the COFF object. The other fields are things that are semantically part of the struct (relocations in a section for exmaple), but are not actually represented that way in the object file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180134 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-23Add some constraints to use of 'returned':Stephen Lin
1) Disallow 'returned' on parameter that is also 'sret' (no sensible semantics, as far as I can tell). 2) Conservatively disallow tail calls through 'returned' parameters that also are 'zext' or 'sext' (for consistency with treatment of other zero-extending and sign-extending operations in tail call position detection...can be revised later to handle situations that can be determined to be safe). This is a new attribute that is not yet used, so there is no impact. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180118 91177308-0d34-0410-b5e6-96231b3b80d8
