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

// Patterns used to select SSE scalar fp arithmetic instructions from
|
|
// either:
|
|
//
|
|
// (1) a scalar fp operation followed by a blend
|
|
//
|
|
// The effect is that the backend no longer emits unnecessary vector
|
|
// insert instructions immediately after SSE scalar fp instructions
|
|
// like addss or mulss.
|
|
//
|
|
// For example, given the following code:
|
|
// __m128 foo(__m128 A, __m128 B) {
|
|
// A[0] += B[0];
|
|
// return A;
|
|
// }
|
|
//
|
|
// Previously we generated:
|
|
// addss %xmm0, %xmm1
|
|
// movss %xmm1, %xmm0
|
|
//
|
|
// We now generate:
|
|
// addss %xmm1, %xmm0
|
|
//
|
|
// (2) a vector packed single/double fp operation followed by a vector insert
|
|
//
|
|
// The effect is that the backend converts the packed fp instruction
|
|
// followed by a vector insert into a single SSE scalar fp instruction.
|
|
//
|
|
// For example, given the following code:
|
|
// __m128 foo(__m128 A, __m128 B) {
|
|
// __m128 C = A + B;
|
|
// return (__m128) {c[0], a[1], a[2], a[3]};
|
|
// }
|
|
//
|
|
// Previously we generated:
|
|
// addps %xmm0, %xmm1
|
|
// movss %xmm1, %xmm0
|
|
//
|
|
// We now generate:
|
|
// addss %xmm1, %xmm0
|
|
|
|
// TODO: Some canonicalization in lowering would simplify the number of
|
|
// patterns we have to try to match.
