2013-02-15AArch64: remove ConstantIsland pass & put literals in separate section.Tim Northover
This implements the review suggestion to simplify the AArch64 backend. If we later discover that we *really* need the extra complexity of the ConstantIslands pass for performance reasons it can be resurrected. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175258 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-15AArch64: refactor frame handling to use movz/movk for overlarge offsets.Tim Northover
In the near future litpools will be in a different section, which means that any access to them is at least two instructions. This makes the case for a movz/movk pair (if total offset <= 32-bits) even more compelling. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175257 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-15BBVectorize: Cap the number of candidate pairs in each instruction groupHal Finkel
For some basic blocks, it is possible to generate many candidate pairs for relatively few pairable instructions. When many (tens of thousands) of these pairs are generated for a single instruction group, the time taken to generate and rank the different vectorization plans can become quite large. As a result, we now cap the number of candidate pairs within each instruction group. This is done by closing out the group once the threshold is reached (set now at 3000 pairs). Although this will limit the overall compile-time impact, this may not be the best way to achieve this result. It might be better, for example, to prune excessive candidate pairs after the fact the prevent the generation of short, but highly-connected groups. We can experiment with this in the future. This change reduces the overall compile-time slowdown of the csa.ll test case in PR15222 to ~5x. If 5x is still considered too large, a lower limit can be used as the default. This represents a functionality change, but only for very large inputs (thus, there is no regression test). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175251 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-14R600/SI: Fix int_SI_fs_interp_constantMichel Danzer
The important fix is that the constant interpolation value is stored in the parameter slot P0, which is encoded as 2. In addition, drop the SI_INTERP_CONST pseudo instruction, pass the parameter slot as an operand to V_INTERP_MOV_F32 instead of hardcoding it there, and add a special operand class for the parameter slots for type checking and pretty printing.
