Sun Jul 11 23:47:20 1999 Andrew Cagney <cagney@b1.cygnus.com>
* 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.
Sun Jul 11 12:03:36 1999 Andrew Cagney <cagney@b1.cygnus.com>
* nrun.c (main): Re-format loop gnu style.
Wed Jul 7 19:56:03 1999 Andrew Cagney <cagney@b1.cygnus.com>
* dv-sockser.c (connected_p): Initialize addrlen.
