_dr_svep_t Union Reference

#include <dr_defines.h>

Data Fields
ushort	u16 [4]
uint	u32 [2]
uint64	u64 [1]

Detailed Description

64-bit Arm Scalable Vector Extension (SVE) predicate register Pn. SVE Pn registers are used to hold mask values that control the operation of some SVE instructions. Pn registers have one bit for every byte of a Zn register to the size of a Pn register is always 1/8 the size of a Zn register. DynamoRIO currently supports up to 512-bit Zn registers and 64-bit Pn registers.
