Three new instructions: umonitor - Sets up a linear address range to be monitored by hardware and activates the monitor. The address range should be a writeback memory caching type. umwait - A hint that allows the processor to stop instruction execution and enter an implementation-dependent optimized state until occurrence of a class of events. tpause - Directs the processor to enter an implementation-dependent optimized state until the TSC reaches the value in EDX:EAX. Also modifying the description of the mfence instruction, as the rep prefix (0xF3) was allowed before, which would conflict with umonitor during disassembly. Before: $ echo 0xf3,0x0f,0xae,0xf0 | llvm-mc -disassemble .text mfence After: $ echo 0xf3,0x0f,0xae,0xf0 | llvm-mc -disassemble .text umonitor %rax Reviewers: craig.topper, zvi Reviewed By: craig.topper Differential Revision: https://reviews.llvm.org/D45253 llvm-svn: 330462 |
