Makes the enum strongly typed instead of interacting with a raw u32
value. While we're at it, we can add helpers to the NWC24Config to make
using code poke at the internals of the class a little bit less and also
make the querying a little nicer to read.
Currently we were using heap allocating maps that last for the entire
duration of the emulator running.
Given the size N of both of these maps are very small (< 20 elements),
we can just make use of an array of pairs and perform linear scans. This
is also fine, given this code isn't particularly "hot" either, so this
won't be run often.
These functions don't touch any class state, so they can be turned into
internal helper functions.
While we're at it, we can move the enumerations as well.
* DSP*Arithmetic: Fix grammar for ANDCF and ANDF
* DSP*Arithmetic: Fix registers used by MOVAX and MOV
* DSP*Branch: Fix documentation for JMPR
* DSP*Branch: Fix HALT encoding ("I think I saw a two")
* DSP*ExtOps: Fix 'LN encoding (The listed encoding was for 'L)
* DSP*ExtOps: Improve documentation for 'LD and 'LDAX
* DSPJitExtOps: Correct typo
* DSP*LoadStore: Remove obsolete comment about pc in SRS (This was fixed in 1419e7e5b2)
* DSP*LoadStore: Fix comments for LRR/SRR
* DSP*Misc: Improve documentation for SBCLR and SBSET
* DSP*Multiplier: Fix MULXAC encoding (The previous encoding was for MULXMVZ)
* DSP*Multiplier: Fix tabs in MULCAC and MULCMVZ (There are some other tabs in comments in the JIT, but these are the only ones that are in instruction comments instead of indicating the corresponding interpreter code. Those other comments can be corrected in a different PR, as they're not documentation related.)
* DSPJitMultiplier: Fix MULXMVZ typo
This also removes the emu folder from the Makefile, and the Config.h file. I'm not entirely sure what build.sh was for, but my best guess is that it was some kind of tool to run emulated DSP code at the same time as the actual DSP code and compare the results. I don't know if it ever worked, but it certainly doesn't work now.
These instructions were already implememented by Dolphin, but never added to the manual. Extension instructions will be handled in a later commit, as wlil instructions that were not previously implememented by Dolphin.
The actual documentation for registers is not changed in this commit; nor are any new registers added. This is purely to make later diffs more readable.
