This uncovers a problem in il/il_aux.c: it passes 3 arguments to
getlines(), but the function expects 4 arguments. I add FALSE as the
4th argument. TRUE would fill in the list of mesregs. IL uses
mesregs during phase 1, but this call to getlines() is in phase 2.
TRUE would leak memory unless I added a call to Ldeleteset(mesregs).
So I pass FALSE.
Functions passed to go() now have a `void *` parameter because
no_action() now takes a `void *`.
*Important:* Do `make clean` to work around a problem and prevent
infinite rebuilds, https://github.com/davidgiven/ack/issues/68
I edit tokens.g in util/LLgen/src, so I regenerate tokens.c. The
regeneration script bootstrap.sh can't find LLgen, but I can run the
same command by typing the path to llgen.
cf/cf_loop.c and share/put.c tried to read the next pointer in an
element of a linked list after freeing the element. ud/ud_copy.c
tried to read beyond the end of the _defs_ array: it only has
_nrexpldefs_ elements, not _nrdefs_ elements.
These bugs caused core dumps on OpenBSD. Its malloc() put _defs_ near
the end of a page, so reading beyond the end crossed into an unmapped
page. Its free() wrote junk bytes and changed the next pointer to
0xdfdfdfdfdfdfdfdf.
This needed lots of refactoring to ego --- not all platforms have ego descr
files, and ego will just crash if you invoke it without one. I think originally
it was never intended that these platforms would be used at -O2 or above.
Plats now only specify the ego descr file if they have one.
These files "magically reappeared" after the conversion from CVS to
Mercurial. The old CVS repository deleted these files but did not
record *when* it deleted these files. The conversion resurrected these
files because they have no history of deletion. These files were
probably deleted before year 1995. The CVS repository begins to record
deletions around 1995.
These files may still appear in older revisions of this Mercurial
repository, when they should already be deleted. There is no way to fix
this, because the CVS repository provides no dates of deletion.
