## DetectArchitecture ##
|
|
#[[
|
|
Does exactly as it sounds. Detects common symbols defined for different architectures and
|
|
adds compile definitions thereof. Namely:
|
|
- arm64
|
|
- arm
|
|
- x86_64
|
|
- x86
|
|
- ia64
|
|
- mips
|
|
- ppc64
|
|
- ppc
|
|
- riscv
|
|
- wasm
|
|
|
|
This file is based off of Yuzu and Dynarmic.
