fn gen_imm_inst_builder(inst: &Rc<InstructionContent>, fmt: &mut Formatter)Expand description
Emit the {name}_imm_s, {name}_imm_u, and (deprecated) {name}_imm
convenience methods for inst, requested via .inst_builder_imm_method(true).
Each generated method has the same shape as inst’s normal builder method,
except that its trailing value operand is taken as an Into<Imm64>
immediate. That immediate is materialized as an iconst (extended to the
controlling type as needed, see InstBuilder::build_imm_const) and then
inst is built with it. The _imm_s variant sign-extends the immediate
while _imm_u zero-extends it; this only matters for i128.
The bare _imm method is kept around for backwards-compatibility, with the
sign-/zero-extension behavior the now-removed *_imm instructions used to
have. It is deprecated in favor of the explicit _imm_s/_imm_u variants.
