optionrom: fix compilation with mingw docker target Two fixes are needed. First, mingw does not have -D_FORTIFY_SOURCE, hence --enable-debug disables optimization. This is not acceptable for ROMs, which should override CFLAGS to force inclusion of -O2. Second, PE stores global constructors and destructors using the following linker script snippet: ___CTOR_LIST__ = .; __CTOR_LIST__ = . ; LONG (-1);(.ctors); (.ctor); (SORT(.ctors.)); LONG (0); ___DTOR_LIST__ = .; __DTOR_LIST__ = . ; LONG (-1); (.dtors); (.dtor); (SORT(.dtors.)); LONG (0); The LONG directives cause the .img files to be 16 bytes too large; the recently added check to signrom.py catches this. To fix this, replace -T and -e options with a linker script. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> 2016-08-09 22:50:40 +02:00			`SECTIONS`
