@item -Wcoverage-mismatch
@opindex Wcoverage-mismatch
Warn if feedback profiles do not match when using the
@option{-fprofile-use} option.
If a source file was changed between @option{-fprofile-gen} and
@option{-fprofile-use}, the files with the profile feedback can fail
to match the source file and GCC can not use the profile feedback
information. By default, this warning is enabled and is treated as an
error. @option{-Wno-coverage-mismatch} can be used to disable the
warning or @option{-Wno-error=coverage-mismatch} can be used to
disable the error. Disable the error for this warning can result in
poorly optimized code, so disabling the error is useful only in the
case of very minor changes such as bug fixes to an existing code-base.
Completely disabling the warning is not recommended.
