2013-02-15If bundle alignment is enabled, do not add data to a fragment with instructionsDerek Schuff
With bundle alignment, instructions all get their own MCFragments (unless they are in a bundle-locked group). For instructions with fixups, this is an MCDataFragment. Emitting actual data (e.g. for .long) attempts to re-use MCDataFragments, which we don't want int this case since it leads to fragments which exceed the bundle size. So, don't reuse them in this case. Also adds a test and fixes some formatting. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175316 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
