why are we not using const?


Dear all,

from comments in the #gcc irc channel, I understood that it is not
advisable for gcc patches to use the const qualifier in function
prototypes. I would like to understand why. Apart from its main
purpose, I believed that the use of 'const' helps the compiler to
optimise the code. Of course, I must be wrong, or the gains must be
very small compared with the reasons for not using 'const', which I
ignore.

Again, I am not proposing using 'const' or changing all the code. I am
just asking the reasons for not using 'const' in order to learn more.

Thanks in advance,

Manuel.
