Hi,
it could always inline it.
For small sizes do that mov and for large sizes do rep stosb on
x86. It is very fast nowadays. Faster than FillChar on my Intel
laptop. (except for mid sizes like 128 bytes)
FillChar is on most platforms an assembly function and FPC *never*
inlines assembly functions.
But having it as an intrinsic would allow the CG to generate optimal
sequences for certain cases, and otherwise fall back to the inherited
method which just inserts a call to the RTL Fill* procedures._______________________________________________
