- 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.
* machinery for nonfatal warnings.
* new backend config-file keywords:
defparam -- like defopt, but each defparam option is required
to have a value when configured via "options".
defflag -- like defopt, but defflag options may not have a value.
Also, on "option FOO", a needs-count style flag
(NFOO, either 0 or 1) is emitted to the .h file.
* Warn about old-style options that aren't defined via def{opt,param,flag}
and which are added to IDENT. (These behave subtly differently
to defopt options when no explicit value is given.)
on tech-kern. (See man page.) Implementation by Greg Hudson.
Also, remove special case for i386 in vector handling, although this code isn't
actually used any more.
