__start_SECNAME and __stop_SECNAME symbols are automatically generated
by ld for orphan sections, i.e. those not explicitely referenced by a
linker script. The symbols are supposed to be placed correspondingly
at the start and the end of the section in output file. In some cases
__start_SECNAME may be placed at the address after the end of the
previous section (if any) and before the start the section. This
happens when following conditions are met:
1. the orphan section is found in more than one input file
2. the orphan section has different alignment requirements across input
files
3. the first instance of the section encountered doesn't have the
greatest alignment requirement
In these conditions resulting output section will be placed at address
after the end of the previous section aligned to the greatest alignment
requirement in the inputs, but __start_SECNAME will be placed at address
after the end of the previous section aligned to the alignment
requirement of the first input in which the section is encountered.
See commit message of r196118 for a concrete example of problems caused
by this bug.
The fix is to place __start_SECNAME inside the section and use ABSOLUTE
directive, rather than placing __start_SECNAME outside the section and
trying to guess address alignment.

o) Add TARGET_ABI to the MIPS toolchain build process. This sets the default

the current default.
o) Set the default GCC cpu type to any specified TARGET_CPUTYPE. This is
necessary to have a working "cc" if e.g. mips64 is specified, as binutils

o) Add support for n32 and n64 ABIs to binutils and GCC.
o) Add additional required libgcc2 stubs for n32 and n64.
o) Add support for the "mips64r2" architecture to GCC. Add the "octeon"
o) When static linking, wrap default libraries in --start-group and

interdependencies between libraries there. This is what other OSes that
support n64 seem to do, as well.
o) Fix our GCC spec to define __mips64 for 64-bit targets, not __mips64__, the
former being what libgcc, etc., check and the latter seemingly being a
misspelling of a hand merge from a Linux spec.
o) When no TARGET_CPUTYPE is specified at build time, make GCC take the default
ISA from the ABI. Our old defaults were too liberal and assumed that 64-bit
ABIs should default to the MIPS64 ISA and that 32-bit ABIs should default to
the MIPS32 ISA, when we are supporting or will support some systems based on
earlier 32-bit and 64-bit ISAs, most notably MIPS-III.
o) Merge a new opcode file (and support code) from a later version of binutils
and add flags and code necessary to support Octeon-specific instructions.
This should also make merging opcodes for other modern architectures easier.

One of the things I really want to do, is to get rid of the limitations
of our current utmp(5) mechanism:
- It only allows 8 byte TTY device names.
- The hostname only allows 16 bytes of storage.
I'm not a big fan of <utmpx.h>, but I think we should at least try to
add parts of it. Unfortunately we cannot implement <utmpx.h>, because we
miss various fields, such as ut_id, ut_pid, etc. The API provided by
libulog shares some similarities with <utmpx.h>, so it shouldn't be too
hard to port these applications eventually. In most simple cases, it
should just be a matter of removing the ulog_ prefix everywhere.
As a bonus, it also implements a function called ulog_login_pseudo(),
which allows unprivileged applications to write log entries, provided
they have a valid file descriptor to a pseudo-terminal master device.
libulog will allow a smoother transition to a new file format by adding
a library interface to deal with utmp/wtmp/lastlog files. I initially
thought about adding the functionality to libutil, but because I'm not
planning on keeping this library around forever, we'd better keep it
separated.
Next items on the todo list:
1. Port applications in the base system (and ports) to libulog, instead
of letting them use <utmp.h>.
2. Remove <utmp.h>, implement <utmpx.h> and reimplement this library on
top.
3. Port as many applications as possible back to <utmpx.h>.

Diagnosed by Ted Anderson:
New signal queuing logic was introduced in 6.15 and allows the signal handlers
to be run explicitly by calling handle_pending_signals, instead of
immediately when the signal is delivered. This function is called at
various places, typically when receiving a EINTR from a slow system call
such as read or write. In the pty exit case, it was called from xwrite,
called from flush, while printing the "exit" message after receiving EOF
when reading from the pty (note that the read did not return EINTR but
zero bytes, indicating EOF). The SIGHUP handler, phup(), called
rechist, which opened the history file and began writing the merged
history to it. This process invoked flush recursively to actually write
the data. In this case, however, the flush noticed it was being called
recursively and decided fail by calling stderror.
My conclusion was that the signal was being handled at a bad time. But
whether to fix flush not to care about the recursive call, or to handle
the signal some other time and when to handle it, was unclear to me.
However, by adding an extra call to handle_pending_signals, just after
process() returns to main(), I was able to avoid the truncated history
after network outages and similar failures. I verified this fix in
version 6.17.
