- ; MakeFunction sets up everything you need to make an assembly function
- ; callable from C and debuggable with a symbolic debugger. It does the following:
- ; - export the function's transition vector
- ; - export the function name
- ; - create a toc entry for the function's transition vector
- ; - create the transition vector, which must contain
- ; - the function entry point (the name of the function)
- ; - the TOC anchor (the predefined variable TOC[tc0])
- ; - tell PPCAsm to create a function entry point symbol for symbolic debuggers
- ; - create a csect for the function (one csect per function lets the
- ; linker do dead code stripping, resulting in smaller executables)
