Bug reports / Re: Some fonts are missing fro...

Last post by Pelle - April 19, 2026, 09:36:31 PM

Like "Cascadia Mono", I can't see it in font name list. But can set in theme file.
Btw: When I was translating rc file, I noticed line 3409 had still read "version 13.00".

The version is in many places, this place is less important. I will fix this some day.

To get some progress here, could you please compile and run the following program. If you see fonts in the output that you want, but don't see in the IDE, please post the following info:

1) The 6 lines following "#1: LOCALE FONT SIGNATURE"
2) The 3-9 lines from "#2: LIST OF FONTS" for the missing font(s).

Windows Defender don't have problems with Pelles C tools.

Is it because Pelles C binaries are not signed? If yes, why?

Probably. Last time I checked the price for a certificate to be trusted was for a company wallet, not a personal one.

Last post by Pelle - April 18, 2026, 05:58:35 PM

I am deliberately filtering the fonts list. At least last time I checked, several years ago, not doing this filtering gave me many fonts I couldn't use.
I will have to think about this (when I can find the time)...

But seriously yes there have been, and are issues, with using the optimizations and extensive testing is always needed for these.  I have many programs using optimizations successfully.

I my experience, enabling the optimizer on poorly written C code is more of a problem than the optimizer itself.

A sanity check is missing in the loop idiom optimizer: triangular numbers. This affects all targets. We'll see when I can fix this...

/* The triangular numbers are given by the following formula:
 * Tn = 1 + 2 + 3 + .. + n = (n * (n + 1)) / 2
 */

It might be a cdecl problem, so 32-bit programs can use stdcall to avoid it.

The trick i=i-(-1); seems to solve the issue :

#include <stdio.h>

int main(void)
{
int i=1, sum=0;
while (i<=100)
{
sum=sum+i;
//i++;
i=i-(-1);
}
printf("i=%d\n",i);
printf("sum=%d\n",sum);
return 0;
}

By the way, uncommenting the line below will output the correct result :

Very typical in my experience for the optimization failures.  Sometimes even just a 1 byte change can make it work, or make it fail.
