* DAGCombine: Let truncates negate extension through extract-subvectorZvi Rackover2018-01-112-66/+37
| | | | | | | | | | | | | | | | | | | | | | Summary: Fold cases such as: (v8i8 truncate (v8i32 extract_subvector (v16i32 sext (v16i8 V), Idx))) -> (v8i8 extract_subvector (v16i8 V), Idx) This can be generalized to cases where the truncate and extend do not fully cancel each other out, but it may require querying the target about profitability.

* [ValueTracking] recognize min/max-of-min/max with notted ops (PR35875)Sanjay Patel2018-01-113-404/+357
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This was originally planned as the fix for: https://bugs.llvm.org/show_bug.cgi?id=35834 ...but simpler transforms handled that case, so I implemented a lesser solution. It turns out we need to handle the case with 'not' ops too because the real code example that we are trying to solve: https://bugs.llvm.org/show_bug.cgi?id=35875 ...has extra uses of the intermediate values, so we can't rely on smaller canonicalizations to get us to the goal. As with rL321672, I've tried to show every possibility in the codegen tests because that's the simplest way to prove we're doing the right thing in the wide variety of permutations of this pattern. We can also show an InstCombine win because we added a fold for this case in: rL321998 / D41603 An Alive proof for one variant of the pattern to show that the InstCombine and codegen results are correct: https://rise4fun.com/Alive/vd1 Name: min3_nots %nx = xor i8 %x, -1 %ny = xor i8 %y, -1 %nz = xor i8 %z, -1 %cmpxz = icmp slt i8 %nx, %nz %minxz = select i1 %cmpxz, i8 %nx, i8 %nz %cmpyz = icmp slt i8 %ny, %nz %minyz = select i1 %cmpyz, i8 %ny, i8 %nz %cmpyx = icmp slt i8 %y, %x %r = select i1 %cmpyx, i8 %minxz, i8 %minyz => %cmpxyz = icmp slt i8 %minxz, %ny %r = select i1 %cmpxyz, i8 %minxz, i8 %ny Name: min3_nots_alt %nx = xor i8 %x, -1 %ny = xor i8 %y, -1 %nz = xor i8 %z, -1 %cmpxz = icmp slt i8 %nx, %nz %minxz = select i1 %cmpxz, i8 %nx, i8 %nz %cmpyz = icmp slt i8 %ny, %nz %minyz = select i1 %cmpyz, i8 %ny, i8 %nz %cmpyx = icmp slt i8 %y, %x %r = select i1 %cmpyx, i8 %minxz, i8 %minyz => %xz = icmp sgt i8 %x, %z %maxxz = select i1 %xz, i8 %x, i8 %z %xyz = icmp sgt i8 %maxxz, %y %maxxyz = select i1 %xyz, i8 %maxxz, i8 %y %r = xor i8 %maxxyz, -1 llvm-svn: 322283

| | | | | | | | | | | | | | The code that is supposed to "Round odd types to the next pow of two" seems broken and as well completely unused (untested).

* [ELF] Fix SysV hash tables with --no-rosegmentShoaib Meenai2018-01-112-0/+16
| | | | | | | | | | | | | | When setting up the chain, we copy over the bucket's previous symbol index, assuming that this index will be 0 (STN_UNDEF) for an unused bucket (marking the end of the chain). When linking with --no-rosegment, however, unused buckets will in fact contain the padding value, and so the hash table will end up containing invalid chains.
