Yes, MSElang produces per happenstance more optimal initial BC-code for the
testcase it seems.
Changing the pascalcode to
"
program test;
procedure p();
var
n1, n2, n3, n4, n5, n6, n7, n8: int32;
TicketsCount: int32;
i1: int32;
begin
for i1:= 0 to 9 do begin
TicketsCount := 0;
for n1 := 0 to 9 do
for n2 := 0 to 9 do
for n3 := 0 to 9 do
for n4 := 0 to 9 do
for n5 := 0 to 9 do
for n6 := 0 to 9 do
for n7 := 0 to 9 do
for n8 := 0 to 9 do
if n1 + n2 + n3 + n4 = n5 + n6 + n7 + n8 then
inc(TicketsCount);
end;
writeln('Found ', TicketsCount, ' tickets.');
end;
begin
p();
end.
"
lets disappear the difference.
Interesting is that changing the C-code to
"
#include <stdio.h>
#include <stdint.h>
int n1, n2, n3, n4, n5, n6, n7, n8;
int i1;
int tickets_count;
int main()
{
for (i1 = 0; i1 < 10; i1++){
tickets_count = 0;
for (n1 = 0; n1 < 10; n1++)
for (n2 = 0; n2 < 10; n2++)
for (n3 = 0; n3 < 10; n3++)
for (n4 = 0; n4 < 10; n4++)
for (n5 = 0; n5 < 10; n5++)
for (n6 = 0; n6 < 10; n6++)
for (n7 = 0; n7 < 10; n7++)
for (n8 = 0; n8 < 10; n8++)
if (n1 + n2 + n3 + n4 == n5 + n6 + n7 + n8)
tickets_count++;
}
printf("Found %i tickets.",tickets_count);
return 0;
}

does not improve the Clang runtime. In attachment the BC-listings and
resulting assembler code.
