Subject: Verify 16bit code doesn't rely on any "discarded" sections.
X-Git-Tag: rel-0.5.0~44
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=9eebe66a9978165cfa91f2266c97fa5d0aa6ef2e;p=seabios.git

Verify 16bit code doesn't rely on any "discarded" sections.

Add linker rule to catch cases where 16bit code tries to access a
    non-existent 32bit variable defined with VAR32VISIBLE.
