function to include crti.o/crtn.o in the STARTFILE and ENDFILE
specs, respectively.
Corresponding GCC ChangeLog entry:
2002-11-19 Jason Thorpe <thorpej@wasabisystems.com>
* gcc.c (The Specs Language): Document spec functions.
(static_spec_functions, lookup_spec_function)
(eval_spec_function, handle_spec_function)
(if_exists_spec_function, alloc_args): New.
(execute): Abort if processing_spec_function is true.
(do_spec_1): Hand off spec to handle_spec_function if %:
is encountered. If processing_spec_function is true,
end any pending argument when the end of the string is reached.
(main): Use alloc_args to allocate the initial argument vector.
* gcc.h (struct spec_function): New.
(lang_specific_spec_functions): New extern.
* config/netbsd-elf.h (STARTFILE_SPEC): Add if-exists(crti%O%s).
(ENDFILE_SPEC): Add if-exists(crtn%O%s).
* config/alpha/netbsd.h (ENDFILE_SPEC): Likewise.
for config_time.h) that contains, for example:
/* Sun Nov 17 05:37:51 2002 GMT */
#define CONFIG_TIME 1037511471
#define CONFIG_YEAR 2002
#define CONFIG_MONTH 11
#define CONFIG_DATE 17
#define CONFIG_HOUR 5
#define CONFIG_MINS 37
#define CONFIG_SECS 51
These values represent the current time as of when config was last
run, so that functions (eg, inittodr()) can use these values instead
of being updated once every year or so with the "current" time.
The associated modification to Makefile.kern.inc makes config_time.h
depend on this depend on this and the kernel Makefile, so that
granularity of kernel builds is not reduced.
means that the appropriate combination of checking for KERNEL_BUILD,
RELEASEDIR, DESTDIR, and/or BSD_PKG_MK, can allow the setting of COPTS
or CFLAGS (or anything else) depending on the specific task at hand.
Personally, I think that per-kernel install rules are the best part.
which bits to build, and to allow "make -j N" actually do something in
parallel:
- build_kernels: for each of ${ALL_KERNELS}, create kern-${NAME} target
which configures & builds the kernel ${NAME}.
- build_kernsets: for each of ${KERNEL_SETS}, create kernset-${NAME} target
to create ${RELEASEDIR}/binary/sets/kern-${NAME}.tgz
- build_releasekernels: for each of ${KERNEL_SETS} ${EXTRA_KERNELS}, create
${RELEASEDIR}/binary/kernel/netbsd-${NAME}.gz (et al)
(The latter two .WAIT until build_kernels has completed)
instead of calling time(3).
This makes rate calculations of crash dumps sensible; in contrast,
subtracting the boot time of the crash dump from the current time of the
running system produces a not-very-meaningful number.
party software packages to the kernel. The statment:
package "../path/to/some/directory/files.package"
is equivalent to the sequence:
prefix "../path/to/some/directory"
include "files.package"
prefix
is already used, we want to remap to another place. The vmcmd must be
completely rebuild, else things does not work as expected, as the vmcmd has
been modified by the first mapping attempt.
