--- Comment #74 from Florian Weimer <fw at gcc dot gnu.org> --- (In reply to Zdenek Sojka from comment #73) > See MISRA C:2012 Rule 17.7: > "... If the return value of a function is intended not to be used > explicitly, it should be cast to the void type. ..." > > It would be helpful if gcc could be used to write MISRA-compliant code, or > at least if it wouldn't generate compilation warnings when the programmer is > targeting MISRA-compliancy. Doesn't this (interpretation of MISRA) mean that compliant code cannot use __attribute__((warn_unused_result))? That doesn't require any GCC changes.
