[AArch64][SVE] Asm: Support for predicated FP operations (FP immediate)
Browse files Browse the repository at this point in the history 
This patch completes support for the following floating point
instructions that take FP immediates:
  FADD*  (addition)
  FSUB   (subtract)
  FSUBR  (subtract reverse form)
  FMUL*  (multiplication)
  FMAX*  (maximum)
  FMAXNM (maximum number)
  FMIN   (maximum)
  FMINNM (maximum number)

All operations are predicated and take a FP immediate operand,
e.g.

  fadd z0.h, p0/m, z0.h, #0.5
  fmin z0.s, p0/m, z0.s, #1.0
        ^___________^ (tied)

* Instructions added in a previous patch.
