8/// \file
9/// This file implements a TargetTransformInfo analysis pass specific to the
10/// X86 target machine. It uses the target's detailed information to provide
11/// more precise answers to certain TTI queries, while letting the target
12/// independent and default TTI implementations handle the rest.
13///
14//===----------------------------------------------------------------------===//
15/// About Cost Model numbers used below it's necessary to say the following:
16/// the numbers correspond to some "generic" X86 CPU instead of usage of a
17/// specific CPU model. Usually the numbers correspond to the CPU where the
18/// feature first appeared. For example, if we do Subtarget.hasSSE42() in
19/// the lookups below the cost is based on Nehalem as that was the first CPU
20/// to support that feature level and thus has most likely the worst case cost,
21/// although we may discard an outlying worst cost from one CPU (e.g. Atom).
22///
23/// Some examples of other technologies/CPUs:
24/// SSE 3 - Pentium4 / Athlon64
25/// SSE 4.1 - Penryn
26/// SSE 4.2 - Nehalem / Silvermont
27/// AVX - Sandy Bridge / Jaguar / Bulldozer
28/// AVX2 - Haswell / Ryzen
29/// AVX-512 - Xeon Phi / Skylake
30///
31/// And some examples of instruction target dependent costs (latency)
32/// divss sqrtss rsqrtss
33/// AMD K7 11-16 19 3
34/// Piledriver 9-24 13-15 5
35/// Jaguar 14 16 2
36/// Pentium II,III 18 30 2
37/// Nehalem 7-14 7-18 3
38/// Haswell 10-13 11 5
39///
40/// Interpreting the 4 TargetCostKind types:
41/// TCK_RecipThroughput and TCK_Latency should try to match the worst case
42/// values reported by the CPU scheduler models (and llvm-mca).
43/// TCK_CodeSize should match the instruction count (e.g. divss = 1), NOT the
44/// actual encoding size of the instruction.
45/// TCK_SizeAndLatency should match the worst case micro-op counts reported by
46/// by the CPU scheduler models (and llvm-mca), to ensure that they are
47/// compatible with the MicroOpBufferSize and LoopMicroOpBufferSize values which are
48/// often used as the cost thresholds where TCK_SizeAndLatency is requested.
