Enable -msoft-quad-float as the default moving forward. A complete build with
this compiler produces no errors and passes known regressions problems (awk,
etc).
XXX - -mhard-quad-float no longer will generate code correctly (internal
compiler problems). This is the case all the way to gcc-current so it's not
an easy fix at the moment but no one should be using hard quad math anyways.
If one doesn't subtract the stack bias back off %fp before attempting
to access variables stored relative to %fp the wrong address is picked up for
all locals and args. So, calls to the FRAME_LOCALS_ADDRESS or

This makes the GMON_PTR_SIZE constant obsolete, however I have not
included the changes to the autoconf machinery that eliminate that
constant completely in order to minimize the changes here (they
will be picked up when we import Binutils 2.12 when it is released).

This is done by removing the .reorder/.noreorder, and moving the

This fixes profiling with libraries built -mabicalls (default on

I can't believe how long this problem has been discussed-but-not-fixed

into the mmap'd region. (reviewed by thorpej.)
This is done to facilitate use as a host tool on not-necessarily-NetBSD
host systems. Specifically, it works around problems discovered on
linux (mostly tested on 2.4.2-smp / RH 7.1, but also seen on other
variants) in which mmap(...MAP_SHARED...) on NFS files doesn't work
properly:

case:
MKBFD If set to "no", disables building of libbfd, libiberty,
and all things that depend on them (binutils/gas/ld, gdb,
dbsym, mdsetimage).
MKGDB If set to "no", disables bulding of gdb.
MKGCC If set to "no", disables building of gcc and the
gcc-related libraries (libg2c, libgcc, libobjc, libstdc++).
These are useful for building platforms for which either of the following
situations are true:
(1) You have no userland from which to run toolchain2netbsd
in order to build the appropriate toolchain build framework.
(2) The platform which you are building requires a newer set
of tools than are currently in the tree (e.g. x86-64, ia64).
- SHLIBDIR Location to install shared libraries if ${USE_SHLIBDIR}
is "yes". Defaults to "/usr/lib".
- USE_SHLIBDIR If "yes", install shared libraries in ${SHLIBDIR}
instead of ${LIBDIR}. Defaults to "no".
Sets ${_LIBSODIR} to the appropriate value.
This may be set by individual Makefiles as well.
- SHLINKDIR Location of shared linker. Defaults to "/usr/libexec".
If != "/usr/libexec", change the dynamic-linker
encoded in shared programs
* Set USE_SHLIBDIR for libraries used by /bin and /sbin:
libc libcrypt libcrypto libedit libipsec libkvm libm libmi387
libtermcap libutil libz
* If ${_LIBSODIR} != ${LIBDIR}, add symlinks from ${LIBDIR}/${LIB}.so*
to ${_LIBSODIR}/${LIB}.so* for compatibility.
* Always install /sbin/init statically (for now)
The net effect of these changes depends on how the variables are set:
1.) If nothing is set or changed, there is no change from the
current behaviour:
- Static /bin, /sbin, and bits of /usr/*
- Dynamic rest
- Shared linker is /usr/libexec/ld*so
2.) If the following make variables are set:
LDSTATIC=
SHLINKDIR=/lib
SHLIBDIR=/lib
Then the behaviour becomes:
- Dynamic tools
- .so libraries used by /bin and /sbin are installed to /lib,
with symlinks from /usr/lib/lib*so to -> /lib/lib*so
where appropriate
- Shared linker is /lib/ld*so
3.) As per 2.), but add the following variable:
USE_SHLIBDIR=yes
This forces all .so's to be instaleld in /lib (with compat
symlinks), not just those tagged by their Makefiles to be.
Again, compat symlinks are installed
1) There is already a destructor that does this. The atexit() is superfluous.
2) If libstdc++ is loaded dynamically by dlopen() and then is removed by
dlclose(), the pointer is no longer valid and the program would core dump
at exit() time. (This caused xmms to core dump at exit when xmms-sid was
installed, for example.)
NOTE: THIS NEEDS TO BE APPLIED TO THE `TOOLCHAIN' VERSION.

* Regen files with proper OS names and version numbers.
* Clean up toolchain2netbsd somewhat, to get it ready to be cross-host

address parts of PR toolchain/14896. This header file is nonstandard
