This is based on the original Portable C Compiler by S. C. Johnson,
written in the late 70's. Even though much of the compiler has been
rewritten, some of the basics still remain.
The goal of pcc is to produce a small, simple, fast and understandable
C99 compiler under a BSD licence.
(for booth the tool build and mknative). gcc's "config.gcc" sets
it if the target is netbsd[2-9], but since the target is w/o version
number in our builds, it has no effect. Found by Nick Hudson,
patch approved by mrg.
defined by the C library for the various m68k ports by borrowing
some #ifs from the i386 port.
Also, align sun2 with the other m68k ports as to whether they
define __bswap{16,32} or bswap{16,32} in their C library (all
now define the __ variants).
This should make the m68k ports build sys/rump again, except
for sun2 which hits another problem later on.
ifreq * arguments to ether_addmulti() and ether_delmulti() to const
struct sockaddr *, since ether_{add,del}multi() only ever read the
sockaddr ifreq member, ifr_addr. Update uses in carp(4) and in
vlan(4).
tells a socket that it should both add a protocol header to tx'd
datagrams and remove the header from rx'd datagrams:
int onoff = 1, s = socket(...);
setsockopt(s, SOL_SOCKET, SO_NOHEADER, &onoff);
2) Add an implementation of (SOL_SOCKET, SO_NOHEADER) for raw IPv4
sockets.
3) Reorganize the protocols' pr_ctloutput implementations a bit.
Consistently return ENOPROTOOPT when an option is unsupported,
and EINVAL if a supported option's arguments are incorrect.
Reorganize the flow of code so that it's more clear how/when
options are passed down the stack until they are handled.
Shorten some pr_ctloutput staircases for readability.
4) Extract common mbuf code into subroutines, add new sockaddr
methods, and introduce a new subroutine, fsocreate(), for reuse
later; use it first in sys_socket():
struct mbuf *m_getsombuf(struct socket *so)
Create an mbuf and make its owner the socket `so'.
struct mbuf *m_intopt(struct socket *so, int val)
Create an mbuf, make its owner the socket `so', put the
int `val' into it, and set its length to sizeof(int).
int fsocreate(..., int *fd)
Create a socket, a la socreate(9), put the socket into the
given LWP's descriptor table, return the descriptor at `fd'
on success.
void *sockaddr_addr(struct sockaddr *sa, socklen_t *slenp)
const void *sockaddr_const_addr(const struct sockaddr *sa, socklen_t *slenp)
Extract a pointer to the address part of a sockaddr. Write
the length of the address part at `slenp', if `slenp' is
not NULL.
socklen_t sockaddr_getlen(const struct sockaddr *sa)
Return the length of a sockaddr. This just evaluates to
sa->sa_len. I only add this for consistency with code that
appears in a portable userland library that I am going to
import.
const struct sockaddr *sockaddr_any(const struct sockaddr *sa)
Return the "don't care" sockaddr in the same family as
`sa'. This is the address a client should sobind(9) if it
does not care the source address and, if applicable, the
port et cetera that it uses.
const void *sockaddr_anyaddr(const struct sockaddr *sa, socklen_t *slenp)
Return the "don't care" sockaddr in the same family as
`sa'. This is the address a client should sobind(9) if it
does not care the source address and, if applicable, the
port et cetera that it uses.
and use kmutex and kcondvar here.
Fix an error introduced with B_ERROR removal where reading at EOM returned EIO.

The mbuf chain wasn't being walked and thus fin_m was not updated to point
to the new first mbuf with data in it.

never be defined to an empty string, because in that case,
if (condition) DPRINTF(...); else err(...);
results in a gcc warning, and possibly worse things.
(no prompt) behaviour - it is now possible to "boot net:dhcp -a" and then
say "disk" at the "Boot:" prompt - result should be equivalent to "boot disk",
but the ofwboot was loaded from the network.
While there fix a few minor errors, and one significant: if the "a" partition
should not start at the beginning of the disk, the previous code failed
to read a disklabel. Use the "c" partition now to find the disklabel now
always.
of the corresponding 32bit architecture.
Use it for the 64bit items in netbsd32_statvfs so that the structure
doesn't collect 8byte alignment (and 4 bytes of trailing padding).
This replaces the 'packed' attribute which wasn't architecture specific
and would cause massive overheads accessing every member of sparc64.
Should allow the MIPS64 port do DTRT.
