// Test cases for Cortex-A53 Erratum 843419
// See ARM-EPM-048406 Cortex_A53_MPCore_Software_Developers_Errata_Notice.pdf
// 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.
