From 30875e1c4b96ec9966901d7ec4e50446394d1273 Mon Sep 17 00:00:00 2001 From: Stu Grossman Date: Sat, 22 Feb 1992 09:06:58 +0000 Subject: * infrun.c, infcmd.c, breakpoint.c, main.c, symfile.c, breakpoint.h, tm-sun4os4.h, tm-sparc.h, sparc-tdep.c, tm-mips.h, mips-tdep.h, tm-sun3.h, tm-68k.h, m68k-tdep.h: Add support for stepping (and nexting) through longjmp(). Also, cleanup breakpoint handling quite a bit by creating explicit breakpoint types instead of using magic breakpoint numbers.
