Tested with 3.3.1 d3ac07ad27
-O4
Win 64 bit
In the code below, compiled with -alr
.section .text.n_p$project1_$$_foo,"ax"
....
# Var a located in register rbx
(and it stays in rbx, until the call to write is prepared)
But if I comment out the "write", and uncomment the "a.w"
# Var a located at rsp+32, size=OS_64
Even the initial 2 lines will then NOT use a register for "a"?
program project1;
{$mode objfpc}{$Inline on}
{$StackFrames off}{$ImplicitExceptions off}
{$ModeSwitch typehelpers}
type
P = ^integer;
PH = type helper for P
procedure w;
end;
procedure PH.w;
begin
write(self^)
end;
var g:p;
procedure Foo;
var a: p;
begin
a:= g;
a^:=1;
//a.w;
write(a^); //
end;
begin
foo;
end.
