+ * sim-resume.c (sim_resume): Ensure that the siggnal [sic] is only
+ passed in when sim_resume is first entered - don't re-pass it
+ after a restart.
+
+Sun Jul 11 23:34:44 1999 Andrew Cagney <cagney@b1.cygnus.com>
+
+ * sim-options.c (standard_option_handler): Add OPTION_LOAD_VMA and
+ OPTION_LOAD_LMA but only when is defined.
+ (standard_options): When SIM_HANDLES_LMA is defined include
+ options --load-lma and --load-vma.
+ (standard_install): Initialize STATE_LOAD_AT_LMA_P.
+
+ * sim-base.h (STATE_LOAD_AT_LMA_P): Define.
+ (struct sim_state_base): Add load_at_lma_p.
+ * sim-hload.c (sim_load): Replace SIM_HANDLES_LMA with
+ STATE_LOAD_AT_LMA_P.
