+/* 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.
+ Default is if the instruction takes ISEQ operand or not.
+ * leaf: indicates that the instruction is "leaf" i.e. it does
+ not introduce new stack frame on top of it.
+ If an instruction handles sp, that can never be a leaf.
