CGen_GetCodeSpace()
Returns a pointer suitable for use with AsmInitPtr():
new ctx[AsmContext];
AsmInitPtr(CGen_GetCodeSpace());
// `@emit` etc go here.CGen_UseCodeSpace(ctx)
Wraps CGen_GetCodeSpace() and AsmInitPtr() together. Also sets up proper error handlers so is the preferred initialisation method:
new ctx[AsmContext];
CGen_UseCodeSpace(ctx);
// `@emit` etc go here.CGen_AddCodeSpace(num)
y_cgen provides a large block of code space to write to, and each time it is written to the next pointer must be updated. This is done after all the generation for one single piece of code is finished by telling y_cgen how much code was written. Thus the next write can continue on from that point:
// `@emit` etc go here.
// Release the handle.
CGen_AddCodeSpace(AsmGetCodeSize(ctx));
