scripts/gdb: implement 'qemu bt'

2021-01-12T11:38:03+00:00

This script first runs the regular gdb's 'bt' command, and then if we are in a coroutine it prints the coroutines backtraces in the order in which they were called. Signed-off-by: Maxim Levitsky Message-Id: <20201217155436.927320-3-mlevitsk@redhat.com> Signed-off-by: Paolo Bonzini

scripts/gdb: fix 'qemu coroutine' when users selects a non topmost stack frame

2021-01-12T11:38:03+00:00

The code that dumps the stack frame works like that: * save current registers * overwrite current registers (including rip/rsp) with coroutine snapshot in the jmpbuf * print backtrace * restore the saved registers. If the user has currently selected a non topmost stack frame in gdb, the above code will still restore the selected frame registers, but the gdb will then lose the selected frame index, which makes it impossible to switch back to frame 0, to continue debugging the executable. Therefore switch temporarily to the topmost frame of the stack for the above code.

scripts/qemugdb/mtree.py: fix up mtree dump

2017-04-07T14:24:56+00:00

Since QEMU has been able to build with native Int128 support this was broken as it attempts to fish values out of the non-existent structure. Also the alias print was trying to make a %x out of gdb.ValueType directly which didn't seem to work. Signed-off-by: Alex Bennée
