f6fb458da3 PR/44148: Henning Petersen: catstrg() does not set the resulting string length. 2010-11-24 17:51:11 +00:00

4c92852a80 remove almost all the ability to build netbsd with an a.out target. 
we're ELF now, and there are many missing checks against OBJECT_FMT.
if we ever consider switching, the we can figure out what new ones
we need but for now it's just clutter.

this doesn't remove any of the support for exec_aout or any actually
required-for-boot a.out support, only the ability to build a netbsd
release in a.out format.  ie, most of this code has been dead for
over a decade.

i've tested builds on vax, amd64, i386, mac68k, macppc, sparc, atari,
amiga, shark, cats, dreamcast, landisk, mmeye and x68k.  this covers
the 5 MACHINE_ARCH's affected, and all the other arch code touched.
it also includes some actual run-time testing of sparc, i386 and
shark, and i performed binary comparison upon amiga and x68k as well.


some minor details relevant:
- move shlib.[ch] from ld.aout_so into ldconfig proper, and cut them
  down to only the parts ldconfig needs
- remove various unused source files
- switch amiga bootblocks to using elf2bb.h instead of aout2bb.h

17bb5b2554 tlst[inptype(...)] is bad C code because inptype() can realloc tlst 
and there's no intermediate sequence point!  We actually hit this on
sh3 with -O2 where gcc4 caches tlst in a register prior to recursive
call to inptype() and if you are unlucky the recursive call needs to
realloc tlst.

Introduce a temp variable to force a sequence point.

f0947b3081 The symbol to define to 1 if a pointer to an int fits in a long is 
INTPTR_IS_LONG, not INTPTR_IS_ULONG -- the latter is unused in
other parts of lint's code.  This stops vax's lint from complaining
about conversion of integer constants to 'unsigned long' in function
argument lists, via a proper define of INT_RSIZE in common/inittyp.c.
sh3 defined this to 0, so was actually not affected, but better to
eradicate the typo there as well.

4228dd3afb Partly redo when to emit warnings for argument type conversions. 
Remove the apparently always true "styp(nt) != SHORT" part of the
innermost test.  Allow atomatic conversion of literals as long as
they fit into the target type.

This should fix some of the lint issues in proplib on some of our
platforms.

62e8b0f3fa Make a minimal attempt at distinguishing between the hosts and the 
targets integer data type value ranges.   For now we just use the
hosts uint64_t for parsing & storing integers constants, and test
against the targets limits and assign appropriately, instead of
sometimes (inappropriately) going via the hosts u_long type.  As
long as none of our architectures have target long or quad data
types strictly larger than 64 bits, we should be fine with this
fix.

Furthermore, as they stand at the moment, we can't use the current
TARG_INT_MAX and TARG_LONG_MAX constants in C preprocessor expressions,
so remove the conditional on them being equal.  Yes, this will
produce dead code for some targets.

This allows an ilp32 host to lint for an lp64 target which uses
e.g. the targets ULONG_MAX constant without triggering an "integer
constant out of range" warning.

OK'ed by christos.
