I have a big noob question again! I basically want to know, how I can find out which processors a certain installation of Clang supports and how do I change the target processor.
Some background to make my question more clear:
Normally I develop applications for Windows and 64bit – back then using the MSVC compiler. By now I changed to the fantastic Clang-Cl and didn’t thought much about processors – I take it automatically target x86-64 because
of Visual Studio?
However, I know that Clang supports more processors (or architectures? What is the difference?) then x86-64. So I wanted to know, which are supported and how do I tell Clang do use a different target?
To give even more background:
I used an old development environment, which provided compiler for the old Playstation CPU – Wikipedia says it is a “32-bit RISC MIPS R3000A-compatible MIPS R3051” (I simply thought it is a R3000). And I started to wonder,
how do I know if Clang supports that old CPU?
So I ran my llvm-config with --targets-built and got:
AArch64 AMDGPU ARM BPF Hexagon Lanai Mips MSP430 NVPTX PowerPC RISCV Sparc SystemZ WebAssembly X86 XCore
I see there “Mips” and “RISCV” but no RISC MIPS or even a R3000 – does that now mean that Clang does not support does old processors? Or does it? What do I do if I encounter a ‘wild’ Clang without llvm-config – can I
still find out its targets? I have no idea and this is why I’m asking.
Thank you in advance for any help!
