* [RISCV] Switch to the Machine SchedulerLuis Marques2019-09-171-22/+22
| | | | | | | | | Most of the test changes are trivial instruction reorderings and differing register allocations, without any obvious performance impact. Differential Revision: https://reviews.llvm.org/D66973 llvm-svn: 372106
* Revert Patch from PhabricatorLuis Marques2019-09-171-22/+22
| | | | | | This reverts r372092 (git commit e38695a0255c9e7b53639f349f8101bae1ce5c04) llvm-svn: 372104

* [RISCV] Add seto pattern expansionLuis Marques2019-04-011-8/+0
| | | | | | | | | Adds a `seto` pattern expansion. Without it the lowerings of `fcmp one` and `fcmp ord` would be inefficient due to an unoptimized double negation. Differential Revision: https://reviews.llvm.org/D59699 llvm-svn: 357378
* [RISCV] Add RV64F codegen supportAlex Bradbury2019-01-311-0/+215
| | | | | | | | | | | | | This requires a little extra work due tothe fact i32 is not a legal type. When call lowering happens post-legalisation (e.g. when an intrinsic was inserted during legalisation). A bitcast from f32 to i32 can't be introduced. This is similar to the challenges with RV32D. To handle this, we introduce target-specific DAG nodes that perform bitcast+anyext for f32->i64 and trunc+bitcast for i64->f32. Differential Revision: https://reviews.llvm.org/D53235 llvm-svn: 352807
* [RISCV] Codegen support for RV32F floating point comparison operationsAlex Bradbury2018-03-211-0/+304
This patch also includes extensive tests targeted at select and br+fcmp IR inputs. A sequence of br+fcmp required support for FPR32 registers to be added to RISCVInstrInfo::storeRegToStackSlot and RISCVInstrInfo::loadRegFromStackSlot. llvm-svn: 328104
