MuAlphaOmegaEpsilon ccce1a03c9 Don't trigger unused-parameter warnings on naked functions
This commit checks if a function is marked with the naked attribute
and, if it is, will silence the emission of any unused-parameter
warning.

Inside a naked function only the usage of basic ASM instructions is
expected. In this context the parameters can actually be used by
fetching them according to the underlying ABI. Since parameters might
be used through ASM instructions, the linter and the compiler will have
a hard time understanding if one of those is unused or not, therefore
no unused-parameter warning should ever be triggered whenever a
function is marked naked.

Douglas Gregor dc35ef9279 Do not diagnose unused-parameter errors in template instantiations. We
will already have done so when the template is declared.
