- fix emitrules() like emitfiles() to deal with the prefix (otherwise it
would attempt to find the file in the normal base for the NORMAL_C rule).
- add emitincludes() which adds include directives for each prefix to the
$INCLUDES variable in the makefile.
- add %INCLUDES to each Makefile.arch to deal with the above.
this makes "prefix" actually work in a usable manner, and now i can move
on to fixing compiler warnings (errors) in the ESP code. :)
to file specifications. The prefixes are arranged in a stack, and
nest, so that file, object, and include specifications are normalized,
and all end up relative to the kernel compile directory.
For example, in the kernel config file:
# Pull in config fragments for kernel crypto
prefix ../crypto-us/sys # push it
cinclude "conf/files.crypto-us" # include it if it's there
prefix # pop it
and in files.crypto-us:
file netinet6/esp_core.c ipsec & ipsec_esp
file netinet6/esp_output.c ipsec & ipsec_esp
file netinet6/esp_input.c ipsec & ipsec_esp
...generates the following in the kernel Makefile:
$S/../crypto-us/sys/netinet6/esp_core.c \
$S/../crypto-us/sys/netinet6/esp_output.c \
$S/../crypto-us/sys/netinet6/esp_input.c \
By placing this all in the kernel config file, all the magic involved in
reaching into non-standard kernel source directories is placed into a file
that the user is expected to edit anyway, and reasonable examples (and
sane defaults, for typical source checkouts) can be provided.
is declared at most once.
* Do option dependency across all def{opt,param, flag}.
* Make the default value of otherwise-unspecified defopt's be 1,
for consistency with non-defopt'ed options.
* Wrap an abstraction layer (macros) around tests for defopt, filesystem,
defparam, etc. to catch outdated defopt-vs-filesystem tests.
Syntax is like the `file' keyword; e.g.:
object arch/i386/i386/mumble.o [mumble] [needs-flag]
Largely from Michael Richardson in PR 3833, with some changes by me.
be included in object dependencies. config(8) is told to generate
a header for a particular option with the new "defopt" keyword, used
in the files.* system description files. Options that are placed in
header files are not given -D... cpp flags.
This approach allows options to be turned into headers incrementally,
rather than all at once, and allows for non-header options, as well.
and the root device:
- New "file-system" keyword is used to configure file systems into
the kernel.
- New way of specifying root device, which allows root file system
type to always be specified. Examples:
config gennetbsd swap generic
config sdnetbsd root on sd0a swap on sd0b
config nfsnetbsd root on nfs
are replaced by:
config gennetbsd root on ? type ?
config sdnetbsd root on sd0a type ffs swap on sd0b
config nfsnetbsd root on ? type nfs
config lenetbsd root on le0 type nfs
Note that specific network interfaces may now be specified as
the root device.
- swapgeneric.c is no longer used; generate a swap*.c file for each
"config" line in the kernel configuration file.

Also, remove special case for i386 in vector handling, although this code isn't
actually used any more.
lists to not have a newline properly emitted. (It was emitting a
newline only if the line position was != 7. However, the only time the
line position was 7 was right after the initial variable assignment
string (e.g. "OBJS=\t") was printed.)
is different than the "machinename" internal variable, read
machinearch's files.${machinearch} and add it to the list of files
for the machine. Also, regardless of whether or not they're different,
create a ${machinearch} sylink (or directory) pointing to the machinearch
include files (or containing them).
and files.kernel has now been completely replaced.
features supported: not nearly as broken as the stuff before
expression support for dependencies
support for 'requires'
no longer generates lots of stupid unnecessary .h files
broke lots of broken stuff, and forced fixing it.
(docs to arrive later)
added '-k' option for continue even after error
documented '-g'
