Honored ContributorI search information about this instruction : int c = a <? b;
A sample of code who compiled with an older version of nios2-elf-gcc (NIOS II EDS 6.0) :int foo(int a, int b)
{
int c = a <? b;
...
}
Honored ContributorLooks like a typo, or something tried to process it in some markup language and got confused.
You'll probably have to work out what was meant from the context.Honored ContributorHonored ContributorIt doesn't look like valid C. The ? operator is only used in a "test ? if_true : if_false" construction. Are you sure that this code line was actually compiled with your older version of gcc? Could it be excluded with an# ifdef ?
Honored Contributorgcc has supported some 'extensions' in the past, their use is discouraged and I don't know the syntax.
There was one for: if (x != 0); return x; And there might have been one for min/max - which could be the one you have there. With enough actual context you should be able to work out what has intended.Honored ContributorOh yes you are right! GCC versions prior to 4.0 supported the <? (min) and >? (max) operators, as well as <?= and >?= to assign min and max values. Those were deprecated in 4.0.
You can probably replace them with MIN() and MAX() macros or functions.Honored Contributor
