pc-bios/s390-ccw/netboot.mak: Ignore Clang's warnings about GNU extensions
|
|
|
|
When compiling the s390-ccw bios with Clang (v14.0), there is currently
|
|
an unuseful warning like this:
|
|
|
|
CC pc-bios/s390-ccw/ipv6.o
|
|
../../roms/SLOF/lib/libnet/ipv6.c:447:18: warning: variable length array
|
|
folded to constant array as an extension [-Wgnu-folding-constant]
|
|
unsigned short raw[ip6size];
|
|
^
|
|
|
|
SLOF is currently GCC-only and cannot be compiled with Clang yet, so
|
|
it is expected that such extensions sneak in there - and as long as
|
|
we don't want to compile the code with a compiler that is neither GCC
|
|
or Clang, it is also not necessary to avoid such extensions.
|
|
|
|
Thus these GNU-extension related warnings are completely useless in
|
|
the s390-ccw bios, especially in the code that is coming from SLOF,
|
|
so we should simply disable the related warnings here now.
