From 7bd1f0c5f9f6797fdde52e9fc18e4a0036197f3c Mon Sep 17 00:00:00 2001 From: Stu Grossman Date: Sun, 8 Sep 1996 23:33:23 +0000 Subject: [PATCH] * blockframe.c (inside_main_func): Cleanup slightly. Move mainsym def into the block it's used in. * configure.in configure: Allow NATDEPFILES to be recognized in .mh files regardless of whitespace. * cpu32bug-rom.c (cpu32bug_cmds): Change load_response string to keep downloads from hanging. * remote-wiggler.c: Add support for flash upgrades. * (wiggler_error): Fix message format. Add new error code. * (wiggler_write_byets): Error code is hex. Report errors with proper routine name. * (wiggler_read_byets): Report errors with proper routine name. * (get_packet): Add support for new flash commands. * (wiggler_load): Call clear_symtab_users() to reset things properly after download. * (flash_xfer_memory bdm_update_flash_command): New funxtions to support flash upgrades for Wiggler. * (_initialize_remote_wiggler): Add `bdm update-flash' command. --- gdb/ChangeLog | 22 +++++++++ gdb/configure | 2 +- gdb/configure.in | 2 +- gdb/cpu32bug-rom.c | 2 +- gdb/remote-wiggler.c | 115 +++++++++++++++++++++++++++++++++++++++++-- 5 files changed, 135 insertions(+), 8 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 0f0eb3339e8..6c438de5d5e 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,25 @@ +Sun Sep 8 15:14:00 1996 Stu Grossman (grossman@critters.cygnus.com) + + * blockframe.c (inside_main_func): Cleanup slightly.
