--- Comment #3 from Eric <ericns1 at spirilis dot net> ---
Further clarifying, creating a whole new function "void check2(void)" inside
MyTemplate which did *not* exist as a virtual function inside MyTemplateParent
produces correct code when begin(uint8_t) tries to call it:
;(call_insn 12 11 15 (parallel [
; (call (mem:QI (symbol_ref/i:SI ("_ZN10MyTemplate6check2Ev")
[flags 0x3] <function_decl 0x7fa8b79c45e8 check2>) [0 check2 S1 A8])
; (const_int 0 [0]))
; (clobber (reg:CC 16 cc))
; ]) my_template.h:34 18 {call_internal}
; (expr_list:REG_EH_REGION (const_int 0 [0])
; (nil))
; (expr_list:SI (use (reg:SI 1 r1))
; (nil)))
bsr __ZN10MyTemplate6check2Ev ; 12 call_internal/2 [length
= 4]
