@ -73,10 +73,10 @@ recompiled, or use "make C=2" to run sparse on the files whether they need to
be recompiled or not. The latter is a fast way to check the whole tree if you
have already built it.
The optional make variable CHECKFLAGS can be used to pass arguments to sparse.
The build system passes -Wbitwise to sparse automatically. To perform
endianness checks, you may define __CHECK_ENDIAN__:
The optional make variable CF can be used to pass arguments to sparse. The
build system passes -Wbitwise to sparse automatically. To perform endianness
checks, you may define __CHECK_ENDIAN__:
make C=2 CHECKFLAGS="-D__CHECK_ENDIAN__"
make C=2 CF="-D__CHECK_ENDIAN__"
These checks are disabled by default as they generate a host of warnings.
