| * | Followup on Proposal to move MIR physical register namespace to '$' sigil. | Puyan Lotfi | 2018-01-31 | 1 | -10/+10 |
| | | | | | | | | | | | | | Discussed here: http://lists.llvm.org/pipermail/llvm-dev/2018-January/120320.html In preparation for adding support for named vregs we are changing the sigil for physical registers in MIR to '$' from '%'. This will prevent name clashes of named physical register with named vregs. llvm-svn: 323922 | ||||
| * | DAGCombine: Let truncates negate extension through extract-subvector | Zvi Rackover | 2018-01-11 | 1 | -66/+21 |
| | | | | | | | | | | | | | | | | | | | | | | | 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.
