/* Some comments about this file's contents:
|
|
|
|
- The new format aims to be editable by C editor of your choice;
|
|
your mileage might vary of course.
|
|
|
|
- Each instructions are in following format:
|
|
|
|
DEFINE_INSN
|
|
instruction_name
|
|
(type operand, type operand, ..)
|
|
(pop_values, ..)
|
|
(return values ..)
|
|
// attr type name contents..
|
|
{
|
|
.. // insn body
|
|
}
|
|
|
|
- Unlike the old format which was line-oriented, you can now place
|
|
newlines and comments at liberal positions.
|
|
|
|
- `DEFINE_INSN` is a keyword.
|
|
|
|
- An instruction name must be a valid C identifier.
|
|
|
|
- Operands, pop values, return values are series of either variable
|
|
declarations, keyword `void`, or keyword `...`. They are much
|
|
like C function declarations.
|
|
|
|
- Attribute pragmas are optional, and can include arbitrary C
|
|
expressions. You can write anything there but as of writing,
|
|
supported attributes are:
|
|
|
|
* sp_inc: Used to dynamically calculate sp increase in
|
|
`insn_stack_increase`.
|
|
|
|
* handles_sp: If it is true, VM deals with sp in the insn.
|
|
|
|
- Attributes can access operands, but not stack (push/pop) variables.
|
|
|
|
- An instruction's body is a pure C block, copied verbatimly into
|
|
the generated C source code.
