Hi,
FillChar is on most platforms an assembly function and FPC *never*
inlines assembly functions.
even without inlining, rep stosb is faster than FillChar:
{$asmmode intel}
procedure repfillchar(var buffer; len: sizeuint; c: byte);
begin
asm
mov al, c
mov rdi, buffer
mov rcx, len
rep stosb
end;
end;
1GB:
fillchar: 364 ms
repfillchar 321 ms
4GB:
fillchar: 1382 ms
repfillchar:1217 ms
Bye,
Benito
