## 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 |
|
||||
- mips64 |
|
||||
- mips |
|
||||
- ppc64 |
|
||||
- ppc |
|
||||
- riscv |
|
||||
- riscv64 |
|
||||
- loongarch64 |
|
||||
- wasm |
|
||||
|
|
||||
Unsupported architectures: |
|
||||
- ARMv2-6 |
|
||||
- m68k |
|
||||
- PIC |
|
||||
|
|
||||
This file WILL NOT detect endian-ness for you. |
|
||||
|
|
||||
This file is based off of Yuzu and Dynarmic. |
