* [Allocator Cleanup] Make the growth of the "slab" size of theChandler Carruth2014-03-282-18/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | BumpPtrAllocator significantly less strange by making it a simple function of the number of slabs allocated rather than by making it a recurrance. I *think* the previous behavior was essentially that the size of the slabs would be doubled after the first 128 were allocated, and then doubled again each time 64 more were allocated, but only if every allocation packed perfectly into the slab size. If not, the wasted space wouldn't be counted toward increasing the size, but allocations over the size threshold *would*. And since the allocations over the size threshold might be much larger than the slab size, this could have somewhat surprising consequences where we rapidly grow the slab size. This currently requires adding state to the allocator to track the number of slabs currently allocated, but that isn't too bad. I'm planning further changes to the allocator that will make this state fall out even more naturally. It still doesn't fully decouple the growth rate from the allocations which are over the size threshold. That fix is coming later. This specific fix will allow making the entire thing into a more stateless device and lifting the parameters into template parameters rather than runtime parameters. llvm-svn: 204993

* [PowerPC] Use a small cleanup pass to remove VSX self copiesHal Finkel2014-03-274-0/+105
| | | | | | | | | | | | As explained in r204976, because of how the allocation of VSX registers interacts with the call-lowering code, we sometimes end up generating self VSX copies. Specifically, things like this: %VSL2<def> = COPY %F2, %VSL2<imp-use,kill> (where %F2 is really a sub-register of %VSL2, and so this copy is a nop) This adds a small cleanup pass to remove these prior to post-RA scheduling. llvm-svn: 204980

* Use the new Windows environment for target detectionSaleem Abdulrasool2014-03-2712-84/+130
| | | | | | | | | This follows the LLVM change to canonicalise the Windows target triple spellings. Rather than treating each Windows environment as a single entity, the environments are now modelled properly as an environment. This is a mechanical change to convert the triple use to reflect that change. llvm-svn: 204978
* Canonicalise Windows target triple spellingsSaleem Abdulrasool2014-03-277-10/+93
| | | | | | | | | | | | | | | | | | | | | | | | | Construct a uniform Windows target triple nomenclature which is congruent to the Linux counterpart. The old triples are normalised to the new canonical form. This cleans up the long-standing issue of odd naming for various Windows environments. There are four different environments on Windows: MSVC: The MS ABI, MSVCRT environment as defined by Microsoft GNU: The MinGW32/MinGW32-W64 environment which uses MSVCRT and auxiliary libraries Itanium: The MSVCRT environment + libc++ built with Itanium ABI Cygnus: The Cygwin environment which uses custom libraries for everything The following spellings are now written as: i686-pc-win32 => i686-pc-windows-msvc i686-pc-mingw32 => i686-pc-windows-gnu i686-pc-cygwin => i686-pc-windows-cygnus This should be sufficiently flexible to allow us to target other windows environments in the future as necessary. llvm-svn: 204977
* [PowerPC] Don't remove self VSX copies in PPCInstrInfo::copyPhysRegHal Finkel2014-03-271-9/+13
| | | | | | | | | | | | | | | Because of how the allocation of VSX registers interacts with the call-lowering code, we sometimes end up generating self VSX copies. Specifically, things like this: %VSL2<def> = COPY %F2, %VSL2<imp-use,kill> (where %F2 is really a sub-register of %VSL2, and so this copy is a nop) The problem is that ExpandPostRAPseudos always assumes that *some* instruction has been inserted, and adds implicit defs to it. This is a problem if no copy was inserted because it can cause subtle problems during post-RA scheduling. These self copies will have to be removed some other way. llvm-svn: 204976

* [PowerPC] Fix v2f64 vector extract and related patternsHal Finkel2014-03-273-4/+22
| | | | | | | | | First, v2f64 vector extract had not been declared legal (and so the existing patterns were not being used). Second, the patterns for that, and for scalar_to_vector, should really be a regclass copy, not a subregister operation, because the VSX registers directly hold both the vector and scalar data. llvm-svn: 204971

* Do not use layout-before to layout atoms.Rui Ueyama2014-03-274-125/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we use both layout-after and layout-before edges to specify atom orders in the resulting executable. We have a complex piece of code in LayoutPass.cpp to deal with both types of layout specifiers. (In the following description, I denote "Atom A having a layout-after edge to B" as "A -> B", and A's layout-before to B as "A => B".) However, that complexity is not really needed for this reason: If there are atoms such that A => B, B -> A is always satisifed, so using only layout- after relationships will yield the same result as the current code. Actually we have a piece of complex code that verifies that, for each A -> B, B => [ X => Y => ... => Z => ] A is satsified, where X, Y, ... Z are all zero-size atoms. We can get rid of the code from our codebase because layout- before is basically redundant. I think we can simplify the code for layout-after even more than this, but I want to just remove this pass for now for simplicity. Layout-before edges are still there for dead-stripping, so this change won't break it. We will remove layout-before in a followup patch once we fix the dead-stripping pass.

Also, check that only if a section has a compressed fragment, then that is the only fragment in the section. Assert-fail if the fragment's data is modified after it is compressed.
