This commits several enhancements done over the last years:
- adddi3 subdi3 insn definitions: Jon Buller (ns32k.md, ns32k.c)
- ffssi2 adddi3 and subdi3 bug fixes: Matthias Pfaller (ns32k.c, ns32k.md)
- movstrsi reimplimentation: Ian Dall (ns32k.c, ns32k.md, ns32k.h)
- 32381 fpu support (extra registers, multiply - add instructions):
Ian Dall (ns32k.c, ns32k.h, ns32k.md)
- divmoddisi: (re) implimentation Ian Dall (ns32k.md)
- use predicate rather than register constraints to allow better code for
non pic case: Ian Dall (ns32k.md, ns32k.c)
- clean up of many macros in ns32k.h: Ian Dall
that this is unnecessary (only permission on the file's directory is
necessary), and it has security implications (see PR #5094). There may be
other race-condition-related implications here that this change fixes, as
well.
command line. This behaviour is how it's documented; it should work
that way. Also fixes building a release tree on a -current system (which
bit me with the sparc secr set I built for pk).
-rpath dir, -shared, -soname, --whole-archive, --no-whole-archive
for compatibility with ELF ports and to aid migration to bintils.
Update manpage with new otions.
size in a shared library. Also, always use our expected size to copy
the item in, on the assumption that doing so generally minimizes the
damage (maybe it's better to just bail out?).

echo 10 / 3 | bc
prints
10 / 3\r\n\r3\r\n
with a stock readline... Our readline does not echo when it does not
have a tty, so it printed:
\r3\n
I removed printing the printing of \r for now...
+ * stor-layout.c (layout_record): Ignore STRUCTURE_SIZE_BOUNDARY if
+ we are packing a structure. This allows a structure with only
+ bytes to be aligned on a byte boundary and have no padding on a
+ m68k.
Gcc used to create code to create trampolines (for nested functions) for
m68k without properly flushing the caches, leading to segmentation violations
on 68040/68060 systems.
Fixed by:
- importing the gcc 2.7.2.3 trampoline creation code into arch/m68k/m68k.h
- adding the OS-specific code for this into arch/m68k/netbsd.h
These changes have been reflected in gcc2netbsd.
- add /usr/include/objc to mtree
- set libobjc/Makefile INCSDIR=/usr/include/objc
- put to-be-installed includes to libobjc/Makefile into INCS=
- add the Objective-C source files to the appropriate lists.
- as the objc include files are installed now, no need to patch most
of the files.
- add /usr/include/obj/* to src/distrib/comp/mi
The changes have been applied to gcc2netbsd, and this script was then used
to create the new version of the files in libobjc/.
PIC support for GCC/arm.
This fix is untested on platforms other than the ARM and is only enabled
if GCC_27_ARM32_PIC_SUPPORT is defined.
These fixes are only required for GCC 2.7 and will not be needed in 2.8+
Norm Rubin and Richard Earnshaw.
PIC support for ARM will form part of the standard GCC tree from 2.8
onwards.
Also default to building soft-float as the resulting code will be a lot
faster then using emulated floating point instructions.
emit a call _cacheflush() to ensure Icache consistency
after writing trampoline code for lexical closures onto the stack
(i.e., into the Dcache).
GCC 2.x (x <= 7.2.2) emits a call cacehflush(), polluting the user
namespace.
memref_referenced_p(); otherwise there are cases where a later set that changes
the memory location may be moved too early, and thus the new value will be
(incorrectly) used where it should not be.
processing of /etc/ld.so.conf in ld.so itself (rather than in /etc/rc):
- added do_conf function and call to it in main to implement internal
processing of /etc/ld.so.conf
- moved maintenance of dir_list to dodir, with an added argument to
dodir to specify whether dir_list should be updated
- added option '-c' to suppress processing of /etc/ld.so.conf
- added option '-S' to suppress processing of std directories (but not
/etc/ld.so.conf)
- modified option -s to suppress processing of _both_ std directories
and /etc/ld.so.conf (i.e., it is equivalent to -cS)--this was done
so that users and scripts that interpret -s as meaning "process
only directories specified on the command line" would not be
startled
From PR #4031. One change was not committed, since it was unnecessary
(option variables are in the BSS, and do not need to be initialized to
0 explicitly).
Plus one change from me:
- getopt() returns -1 when completed, not EOF.
of the password file entry, not just first password file entry containing
$LOGNAME. (Fixes PR 3298 with a fix similar to that supplied in that PR
by Era Eriksson.)
* Ignore SIGINT and SIGQUIT (signals which are sent to the whole process
group) before editing sessions, and restore handler afterward, so that
SIGINTs and SIGQUITs delivered while editing (e.g. via Control-G in emacs)
don't cause send-pr to abort. (Fixes PRs 2530 and 2658.)
* When aborting because of a signal, if the PR has been modified from the
standard form, don't delete the edited copy (to prevent peoples' work
from being lost accidentally). (Fixes PR 2057.)
had not be implemented. It would cause an "adress space leak" and, if
the same object would opened multiple time, unwanted relocations.
Re: Comment from Chris:
"The a.out ld.so has some problems with dlclose. It doesn't properly
unmap objects which are dlclosed. That's a known problem (though a
serious one for programs which dlopen then dlclose lots of objects,
because it causes address space exhaustion), but it has a
previously-unknown side-effect.
If a single object is dlopened, then dlclosed, then dlopened _again_,
the relocations will be processed again. That causes obvious
problems."
Added a new patch mechanism to gcc2netbsd so changes from the FSF source
are seen in gcc2netbsd. Sync some Makefiles to output of current gcc2netbsd.
(Cosmetic changes only to the Makefiles.)
