Rename compiler-warning-disable variables from
GCC_NO_warning
to
CC_WNO_warning
where warning is the full warning name as used by the compiler.
GCC_NO_IMPLICIT_FALLTHRU is CC_WNO_IMPLICIT_FALLTHROUGH
Using the convention CC_compilerflag, where compilerflag
is based on the full compiler flag name.
GCC_NO_FORMAT_TRUNCATION -Wno-format-truncation (GCC 7/8)
GCC_NO_STRINGOP_TRUNCATION -Wno-stringop-truncation (GCC 8)
GCC_NO_STRINGOP_OVERFLOW -Wno-stringop-overflow (GCC 8)
GCC_NO_CAST_FUNCTION_TYPE -Wno-cast-function-type (GCC 8)
use these to turn off warnings for most GCC-8 complaints. many
of these are false positives, most of the real bugs are already
commited, or are yet to come.
we plan to introduce versions of (some?) of these that use the
"-Wno-error=" form, which still displays the warnings but does
not make it an error, and all of the above will be re-considered
as either being "fix me" (warning still displayed) or "warning
is wrong."
This allows the ramdisk used in the incoming support for full-disk encryption to contain crunched binaries (much like sysinst) while booting a regular system (unlike sysinst).
Also pass "-ppax" in an attempt to get improved performance,
but this doesn't really work in the typical case, because the
install ramdisk image contains a version of pax(1) that doesn't
support the -M flag. (MAKEDEV detects the failure and falls back
to using mknod(8) as usual.)
Removes a load of code that is easier done as a script.
Whenever init exits, use a different error number. Since it is difficult
for init to output messages when /dev/console is absent, having the exit
code reported by the kernel panic gives a chance of identifying the fault.
Also exit if MAKEDEV fails to create /dev/console.
MAKEDEV, MAKEDEV.subr and MAKEDEV.local in the set of files that are
copied if they exist.
Now booting an INSTALL kernel with an embedded ramdisk correctly creates
/dev again, fixing a problem introduced when MAKEDEV.subr was created a
few days ago.
