From: Jim Kingdon Date: Fri, 1 Oct 1993 20:48:14 +0000 (+0000) Subject: * printcmd.c (do_examine): Make meaning of 'h', 'w', and 'g' not X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f73b07c9d26a2baf9463349b2526f646d6d5238b;p=binutils-gdb.git * printcmd.c (do_examine): Make meaning of 'h', 'w', and 'g' not depend on builtin_type_*. Instead, it is always 2, 4, and 8 bytes like the documentation says. * printcmd.c (decode_format) [CC_HAS_LONG_LONG]: Remove 'l' as synonym for 'g'. This was never documented, it shouldn't depend on CC_HAS_LONG_LONG, and I don't see what's wrong with 'g'. --- diff --git a/gdb/ChangeLog b/gdb/ChangeLog index bbaf1a501a2..67df29da70e 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,12 @@ +Fri Oct 1 14:54:46 1993 Jim Kingdon (kingdon@lioth.cygnus.com) + + * printcmd.c (do_examine): Make meaning of 'h', 'w', and 'g' not + depend on builtin_type_*.
