| // 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. |
