a mirtoconf check, would’ve been a real problem on an LP64 platform
• sh.h: work around a bad interaction between -Wformat on gcc and manual
string pooling for T_synerr, which is used in place of a format string
in some places
– possible integer overflows in memory allocation, mostly
‣ multiplication: all are checked now
‣ addition: reviewed them, most were “proven” or guessed to be
“almost” impossible to run over (e.g. when we have a string
whose length is taken it is assumed that the length will be
more than only a few bytes below SIZE_MAX, since code and
stack have to fit); some are checked now (e.g. when one of
the summands is an off_t); most of the unchecked ones are
annotated now
⇒ cost (MirBSD/i386 static): +76 .text
⇒ cost (Debian sid/i386): +779 .text -4 .data
– on Linux targets, setuid() setresuid() setresgid() can fail
with EAGAIN; check for that and, if so, warn once and retry
infinitely (other targets to be added later once we know that
they are “insane”)
⇒ cost (Debian sid/i386): +192 .text (includes .rodata)
• setmode.c: Do overflow checking for realloc() too; switch back
from calloc() to a checked malloc() for simplification while there
• define -DIN_MKSH and let setmode.c look a tad nicer while here
‣ -combine → -c combine
‣ -llvm → -c llvm -O
‣ -llvm=x → -c llvm -o x
‣ -valgrind → -g²
• new option -v (version)
• new options -c (compile mode³), -o (opt flags), -O (reset opt flags)
• opt flags default to -std-compile-opts (llvm) now
• support⁴ the LLVM dragonegg plugin for GCC
• sync list of removed files (*.bc, *.ll, add missing Rebuild.sh)
① old options still valid but emit a warning
② except this one
③ compile modes are:
• normal
• makefile (-M)
• combine (old -combine, new -c combine)
• dragonegg (new -c dragonegg)
• llvm (old -llvm, old -llvm=*, new -c llvm)
the first two are not settable via -c though…
④ sample use:
tg@seduxbox:~/x$ export PATH=$PATH:/opt/llvm/bin
tg@seduxbox:~/x$ CC='/opt/gcc-4.5.1/bin/gcc-4.5.1 -fplugin=/opt/llvm/lib/dragonegg.so' sh ../mksh/Build.sh -c dragonegg -r
Thanks to «dileX:#grml» for giving ssh access.
now that we use the same name as quiet-by-design autoconf
to please ccache anyway (and no we will not become quiet,
I can't usually get my hand on a buildd's conftest.log)
MKSH_S_EDIT for small (Emacs) editing mode, MKSH_S_FEAT for all the dis-
abled language features), which can be set to 0 despite MKSH_SMALL being
defined to re-enable the Vi command line editing mode (which I wouldn't,
but fits into the general mastermind scheme)
libc function realpath(3) which may not be available on the target
system; compile the realpath builtin unconditionally
looks fine to me, but review is appreciated; this is (very) lightly
based upon MirBSD libc’s realpath(3) and pdksh’s get_phys_path()
Build.sh but use 'if defined(PRECOND) && !defined(TOBEDEFINED)'if possible
* for all of the source code, drop annotations "imake style" (if we check
for specific OSes, bad, instead of using mirtoconf checks proper) and
"conditions correct?" (if I'm not entirely sure if that #if catches all
cases and no false positives) where I can see it by grepping immediately
* bump mksh patchlevel
* refresh Makefiles
the state of the C Præprocessor at configuration time (simple checks, i.e.
set/unset, set+1/set+!1/unset, and more complex checks), including verbose
output; related cosmetics and variable naming cleanup
QNX 6.4 is out, which has a different waitfor() in <libutil.h>, which
we by definition of __NO_EXT_QNX do not want to use. They are in the
process of porting the NetBSD® pkgsrc® repository to it.
The /bin/ed situation hasn’t improved yet though.
• expose “#ifdef MKSH_MIDNIGHTBSD01ASH_COMPAT” just in case they decide to
require it and show it in the ksh version automatically
• sync the use of non-ASCII characters over files (unification)
fix the regression test’s results while here, which have been
broken since cid 10049D9BE5254CE65B8
• get rid of separate copyright file which was intended for De-
bian; track down commits in all files of oksh-mirbsd and mksh
to get correct copyright years per-file, as is BSD custom
similarily simple one from scratch, which however performs
better than espie's with AFREE_DEBUG enabled which took away
the benefit of the double-linked-list approach
all of (core) mksh is now MirOS licenced
compile all source files at once using -fwhole-program --combine,
similarily to how it used to be done in older mksh versions, except
that the flags are now hardcoded; tested with llvm-gcc4.2 from MirPorts
