I've only had to deal with this on x86-64 Linux, and I worked from this reference document: https://refspecs.linuxbase.org/elf/x86_64-abi-0.99.pdf (section 3.2) [0]

I imagine similar documents exist for each OS-architecture pairing, since the ABI is a convention that (ideally) everyone will agree on.

If you need a definitive answer for some particular OS-architecture pairing, you might ask within a development community that also needs to support that ABI. E.g., gcc, LLVM, lldb, gdb.

[0] IIRC: Even after reading that doc I was unclear on a few details. I got clarification by writing some minimal examples and looking at the assembly that gcc produces. Note that you may need to disable inlining and optimization, or else you might draw the wrong conclusions from the generated assembly.
