I made a few tests on Ubuntu 64 bits (arch x86_64) with variations on a
small test program:
var
E2: Byte= 3;
E1: LongWord= 1;
E: QWord;
begin
E:= (1000*E1) shl E2;
writeln( 'E2', E2);
writeln( 'E1', E1);
writeln( 'E', E);
end.
In the assembly window, shl is computed
Sorry, my bad.
I hadn't got Thunderbird configured right. All mail from this list just showed
the list address in the 'From' field.
Now fixed it.
Edit > Preferences > Advanced >
"Show only display name for people in my address book"
which was checked.
Cheers,
Pete
Can we say that in Pascal the result of:
E1 shl E2
is of same type as E1 ?
(so if E1 is LongWord then result is LongWord also?)
What if there is an expression on left side:
(E1*x) shl E2
Will E1*x promote to 64 bits (on 64 bit target)?
See documentation on
