machine independent, with the only dependency being the binary format
to build. We only expect to build ELF on alpha although we'll need
ECOFF compatibility with Digital Unix.
definitions for architectures that we don't have libc MD source for.
Change 'int' to 'long' in sigjmp_buf and jmp_buf structures so
that they are suitable for the register size on both i386 and alpha.
Although FreeBSD defines these structures differently to NetBSD,
the element size is now the same.
If Bruce doesn't like this [8-)], we'll need to add a typedef to
each <machine/setjmp.h> and use that in <setjmp.h>.
doesn't know about getvfsbyname() and the vfsconf structure. This
disables the -fstype option if compiled with a pre-processor that
defines __NetBSD__. With the FreeBSD built pre-processor, find can only
be built with the FreeBSD libc. So when running with a NetBSD kernel,
FreeBSD's libc will have to return ENOSYS for things that NetBSD
doesn't support. That's life in a hybrid world.
rely on undocumented behavior.
The following fixes were obtained from OpenBSD:
o -Wall fixes to tlist array initialization and assignment used
as truth value.
o Use a restricted environment.
o Improved error message when shutdown fails to exec reboot or halt.
referenced by the build of user-space libraries. These files were
obtained from NetBSD (with ansi.h being modified to reflect the FreeBSD
off_t and pid_t implementation).
stale obj directory and we wouldn't want to do that! I trust he knows
what he's talking about. 8-)
Also avoid building libm at all until the NetBSD asm code is imported.
I wrongly commented this out last time. Oops.
- don't declare `struct arpcom' except in the kernel, so that there is no
dependency on <net/if.h> except in the kernel. This may break something
else.
- spell ETHER_ADDR_LEN as 6 again, so that there is no dependency on
<net/ethernet.h> even in the kernel.
reduces to a relocatable symbol plus an offset. This preserves
the symbol type information (function vs. object). It is important
for SVR4-style weak symbols, e.g., "#pragma weak foo=bar". Without
this change, the linker complains that the jmpslot entry is not a
function.
(I completely mis-read the rfc last time 'round!)
This means:
o Better CCP/WARN Reset diagnostics.
o After we've sent a REQ and before we've received an ACK, we drop
incoming compressed data and send another REQ.
o Before sending an ACK, re-sequence all pending PRI_NORMAL data in
the modem queue so that pending packets won't get to the peer
*after* the ResetAck.
o Send ACKs with the `identifier' from the REQ frame.
o After we've received a correct ACK, duplicate ACKs are ok (and will
reset our history).
o Incorrect ACKs (not matching the last REQ) are moaned about and dropped.
Also,
o Calculate the correct FCS after compressing a packet. DEFLATE
*may* produce an mbuf with more than a single link in the chain,
but HdlcOutput didn't know how to calculate the FCS :-(
o Make `struct fsm'::reqid a u_char, not an int.
This fix will prevent us from sending id `255' 2,000,000,000 times
before wrapping to `0' for another 2,000,000,000 sends :-/
o Bump the version number a little.
The end result: DEFLATE now works over an unreliable link layer.
I can txfr a 1.5Mb kernel over a (rather bad) null-modem
cable at an average of 21679 bytes per second using rcp.
Repeat after me: Don't test compression using a loopback ppp/tcp setup as
we never lose packets and therefore never have to reset!
(accent_key + space does still print the accent letter too, as in
the previous commit.)
Requested by a couple of users.
- Clear the accent flag when the next_screen key is pressed.
- Added some comment lines regarding accent key processing.
that this source is compiled against. This source is referenced by
install which is needed as a build tool and must be able to compile
against NetBSD headers and libraries if we have a hope of supporting
another architecture.
With this change, that's two working programs down and 3945 (?) to go.
The other one was make, but that didn't need any changes to work under
FreeBSD/Alpha. 8-)
to another architecture (in this case the Alpha) we can continue to use
the host csu objects (from NetBSD). This should be a non-function change
to FreeBSD/i386.
