-sys/lib/libkern builds as library per default (as it was documented all
the time)
-ports able to LKM set "KERN_AS=obj" explicitely in their Makefiles
(for now; should depend on actual "option LKM" or -better- functions
included for LKM use should be pulled in by a stub)
-always link libcompat before libkern - libkern stuff can be referred to
by libcompat, but not the other way
a HAVE_GCC28 check-variable that can now be used to add other gcc-2.8
flags in cases where they may be useful, or to remove gcc 2.7.2 "bug
workaround" flags.)
the kernel on most platforms, including all of the entry-level platforms.
2. Kill the comments and options for load address selection.
3. Kill the default -g.
--entries / remove kernel entry from locore / reorganize vector entry
--code. Enables access to stack frames transitively w.r.t. palcode
--vectors, e.g. upward traceback works, inverting (possibly several)
--kernel vectors. Until now, all trackbacks ended at the first-reached
--instance of trap(), which was totally useless as there is no mystery
--to trap->panic->cpu_reboot
into the 'argument variables' section.
* define variables for CPP and SIZE, defaulting to cpp and size, respectively.
* kill HOSTED_C*, since it's no longer used.
* use ${SIZE} rather than using 'size' directly, so it can be overridden for
cross-builds.
* generate assym.h via assym.s and an awk script.
Lets users over-ride with makeoptions COPTS="..." in kernel config files.
Leave `mandatory' flags (like -msoft-float which on m68k enforces no
FP in kernel) in CFLAGS.
-Werror -Wall -Wstrict-prototypes -Wmissing-prototypes
-Wcast-qual -Wno-format
(if not already set). -Wno-format is necessary because of the few
bits of code in the tree that use NetBSD's special kernel printf()
formats, and because there are a few bits of code that try to use the 'q'
modifier to print int64_t's (but int64_t's are only 'long' on the
alpha, not 'long long').
ELF-outputting version of the assembler. (It was dying when it saw
some CPP line number markers.) This is temporary. (Workaround suggested
by Matt Thomas.)
* Make S expand to an absolute path at compile time.
* Use `-S' rather than `-x' to remove debugging symbols.
* Garbage collect unused variables.
* Reverse a handful of port-specific changes that do not correspond to
the common build model and are not needed.
Support for AXPpci CPUs,
Support for AlphaStation 600 CPUs,
new boot block structure, which requires an 'installboot'
program and works a lot like the NetBSD/sparc boot blocks.
