Subject: [build] Use -Wno-decl when running sparse
X-Git-Tag: v1.20.1~1527
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e5cbfefdf3dc337afc71ccd2fbe4126ee5976bfc;p=thirdparty%2Fipxe.git

[build] Use -Wno-decl when running sparse

Linker table entries must be non-static in order to avoid being
completely optimised away by some versions of gcc.  Use -Wno-decl to
prevent sparse from warning about these, since the alternative would
be to litter the code with otherwise unnecessary "extern"
declarations.
