Takes an u32, an u64, a [[#CodeRange]], a [[#CodeRange]], a [[#Struct32]], a type-0x5 input buffer, a type-0x6 output buffer, and returns an output s32, a [[#CodeRange]], a [[#CodeRange]].

An error is thrown if the funcptr in state for the "nnjitpluginGenerateCode" symbol is not set.

This does a bunch of validation. Then eventually CodeMemory/TransferMemory is mapped, the above symbol funcptr is called, runs more validation, and unmaps CodeMemory/TransferMemory. On success, this runs cache operations. Then this returns.

The funcptr is called with the following params: x0 = s32* out, x1 = {ptr to output [[#CodeRange]] initialized with the input [[#CodeRange]] and with the second u64 cleared}, x2 = {ptr to output [[#CodeRange]] initialized with the input [[#CodeRange]] and with the second u64 cleared}, x3 = {ptr to struct on stack which is the same as the one used for the "nnjitpluginOnPrepared" symbol, except +0x30/+0x38 is set to data from state}, x4 = cmd input u64, x5 = InBuffer addr, x6 = InBuffer size, x7 = {ptr to input [[#CodeRange]]}, sp0 = {ptr to input [[#CodeRange]]}, sp8 = {ptr to input [[#Struct32]]}, sp16 = cmd input u32, sp24 = OutBuffer addr, sp32 = OutBuffer size.

The input/output [[#CodeRange]] structs are validated as follows, where stateval is the first/second CodeMemory [[#CreateJitEnvironment|size]] for the first/second [[#CodeRange]]:

* TransferMemory init is done here. An ASLR'd address for the TransferMemory mapped-address is determined, which will then be reused for all later mappings.

* CodeMemory init func-calling is done for both regions, where w1={first output from "nnjitpluginConfigure" above}. Likewise with the TransferMemory, with w1={second output from "nnjitpluginConfigure" above}.

* "nnjitpluginOnPrepared", error is handled on failure. Before/after calling this symbol funcptr, the TransferMemory is mapped/unmapped. The symbol funcptr is called with x0 = {ptr to struct on stack}. The struct has following structure: +0 = 0x20-bytes of data from state, +0x20 = TransferMemory map-addr, +0x28 = TransferMemory size, and +0x30 size 0x10-bytes is cleared.
