Thu Jul 25 19:41:31 1996  Fred Fish  <fnf@cygnus.com>

for a rather huge set of changes.  I was going to put them here, but it
made cvs dump core.  :-(

94d4b71373 * Makefile.in (TAGS): Use variables directly, rather than using

	tm-i386v.h is apparently OK.
	* config/i386/xm-symmetry.h [_SEQUENT_]: Define HAVE_TERMIOS not
	HAVE_TERMIO.  Define MEM_FNS_DECLARED, NEED_POSIX_SETPGID, and
	USE_O_NOCTTY.

Fred Fish
bf349b77fa Add OBJF_SYMS flag and use it to decide whether or not we have already
tried to read symbols from a file, for mapped objfiles.  This fixes a
memory leak (actually a constant memory growth) due to reading symbol
files with no debug info and thus generating no psymtabs or symtabs.
Most typically happened with shared libraries.
1992-03-28 21:06:23 +00:00
Fred Fish
5e2e79f859 Many changes, most related to creating entry point information on a per-objfile
basis.  See comments in objfiles.h and details in ChangeLog.  Also remove
redundant definitions of FRAME_CHAIN_VALID from most of the tm-* files and
use a default definition in frame.h.
