- // ------------------------------------------------------
- // Global variables do not have any '.' in their names.

- // These are maily function names and global variable names.
- // -------------------------------------------------------
- // Functions and auto variables.
- // Names are mangled as <prefix><funcname>.<id>.<varname>
- // Where prefix is a special char '@' and id is any one of
- // the following
- // .auto. - an automatic var of a function.
- // .temp. - temproray data of a function.
- // .ret. - return value label for a function.
- // .frame. - Frame label for a function where retval, args
- // and temps are stored.
- // .args. - Label used to pass arguments to a direct call.
- // Example - Function name: @foo
- // Its frame: @foo.frame.
- // Its retval: @foo.ret.
- // Its local vars: @foo.auto.a
- // Its temp data: @foo.temp.
- // Its arg passing: @foo.args.
- //----------------------------------------------
- // Libcall - compiler generated libcall names must have a .lib.
- // This id will be used to emit extern decls for libcalls.
- // Example - libcall name: @sra_i8.lib.
- // To pass args: @sra_i8.args.
- // To return val: @sra_i8.ret.
