The architecture definition of Speculatively executed

Hi everyone, The Chapter Performance Monitors Extension in Arm ARM gives a definition "Speculatively executed", which says: An instruction or operation that is counted by an event when it MIGHT be...
Will cortex-a7's speculative access trigger abort?

Hi, if coretex-a7 speculative accesses a virtual memory address which is not mapped to physical address, will it trigger a data abort as the normal instruction does? Thanks! Take below instructions...
