is this bug merge with 4.9

Hi Jonathan,

The last 4.9 version of the ARM embedded toolchain does not include that fix. That version was released before the fix was ready in FSF GCC. All of our GCC 5 based ARM embedded toolchain releases have that fix though, so we encourage you to migrate to the 5 series.

Best regards.

Hi,

Is there a warning that we can activate to check to no code is using strct passed by value ?

regards

Jonathan

I am not aware of such a warning. The closest I could find is -Waggregate-return.

Best regards.

Hi Jonathan,

You can look through https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html

But all I could find was:
-Waggregate-return
    Warn if any functions that return structures or unions are defined or called. (In languages where you can return an array, this also elicits a warning.)

So this will tell you if a function returns a struct (which is passed by value). For passing structs by value as arguments, I wasn't able to find any warning.

Note I didnt check whether this warning was present in gcc 5.

Cheers,
Andre

Oops, seems Thomas was faster ;)

Thank-you for your information.

This is exactly what I find.
