// for full erratum details.

|
// In Summary
|
|
// 1.)
|
|
// ADRP (0xff8 or 0xffc).
|
|
// 2.)
|
|
// - load or store single register or either integer or vector registers.
|
|
// - STP or STNP of either vector or vector registers.
|
|
// - Advanced SIMD ST1 store instruction.
|
|
// - Must not write Rn.
|
|
// 3.) optional instruction, can't be a branch, must not write Rn, may read Rn.
|
|
// 4.) A load or store instruction from the Load/Store register unsigned
|
|
// immediate class using Rn as the base register.
|
|
|
|
// Each section contains a sequence of instructions that should be recognized
|
|
// as erratum 843419. The test cases cover the major variations such as:
|
|
// - adrp starts at 0xfff8 or 0xfffc.
|
|
// - Variations in instruction class for instruction 2.
|
|
// - Optional instruction 3 present or not.
|
|
// - Load or store for instruction 4.
