There is no problem and I am not using it. The -O4 and above are same as with -O3, so it doesn't make any sense for anyone to get above than -O3 since it doesn't exists in ideal. Why not add -O3 instead of -O4 to be more realistic? Also, avoid the blindspot when GCC addes -O4 in future that might break other application that use libraw. It can makes difficult to debug. > I'm also Cc'ed this letter to libraw author Alex Tutubalin. > Alex, could you provide more information about compile optimization? The URL of GCC docuement isn't good enough? Unless there is an unoffical -O4 patch? Feel free to correct me. It's only a suggest, so the choice is your.
