Primarily refines all of the instructions with accurate latency and micro-op information. Refinements largely focus on the NEON instructions. Additionally, a few advanced features are modeled, including forwarding for MAC instructions and hazards for floating point SQRT and DIV. Lastly, the issue-width is reduced to three so that the scheduler will better accommodate the narrower decode and dispatch width. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@218627 91177308-0d34-0410-b5e6-96231b3b80d8

// Contains all of the Cortex-A57 specific SchedWriteRes types. The approach
|
|
// below is to define a generic SchedWriteRes for every combination of
|
|
// latency and microOps. The naming conventions is to use a prefix, one field
|
|
// for latency, and one or more microOp count/type designators.
|
|
// Prefix: A57Write
|
|
// Latency: #cyc
|
|
// MicroOp Count/Types: #(B|I|M|L|S|X|W|V)
|
|
//
|
|
// e.g. A57Write_6cyc_1I_6S_4V means the total latency is 6 and there are
|
|
// 11 micro-ops to be issued down one I pipe, six S pipes and four V pipes.
