Description

Instruction from the BSTART group.

Pseudocode (informative)

// Execute L.BSTART.FP as defined by the BSTART semantics.

Encoding Notes

  • Closes the current bundle, initializes the next bundle descriptor, and selects its transfer and execution kind.
  • Bare L.BSTART.FP CALL preserves ra. A returning call must be preceded by SETRET or C.SETRET with an explicit return label.
