Jim Lin	242ddd5089	[RISCV][NFC] Add a single space after comma for VType ... In most of cases, it has a single space after comma in assembly operands. Reviewed By: craig.topper Differential Revision: https://reviews.llvm.org/D103790	2021-06-09 11:18:22 +08:00
Craig Topper	c09b37553e	[RISCV] Remove dead code from fixed-vectors-abs.ll test cases. NFC ... We had two pointer arguments and a dead load presumably copied from a binary operation test and modified into unary abs.	2021-06-08 11:24:23 -07:00
Craig Topper	fdf10e6197	[RISCV] Use X0 as destination of inserted vsetvli when possible. ... We aren't going to connect the result to anything so we might as well avoid allocating a register.

Fraser Cormack	797e580db9	[RISCV][NFC] Simplify test run lines ... Several tests had -verify-machineinstrs twice, and several tests were explicitly specifying the default FileCheck prefix of CHECK.	2021-05-13 12:41:00 +01:00
Craig Topper	72ecf2f43f	[RISCV] Optimize fixed vector ABS. Fix crash on scalable vector ABS for SEW=64 with RV32. ... The default fixed vector expansion uses sra+xor+add since it can't see that smax is legal due to our custom handling. So we select smax(X, sub(0, X)) manually. Scalable vectors are able to use the smax expansion automatically for most cases. It crashes in one case because getConstant can't build a SPLAT_VECTOR for nxvXi64 when i64 scalars aren't legal. So we manually emit a SPLAT_VECTOR_I64 for that case. Reviewed By: frasercrmck Differential Revision: https://reviews.llvm.org/D97991	2021-03-09 08:51:03 -08:00
