Intel MPX bound violation support.
First 5 patches of the series are preparation for the
bound violation handler.
Preparation:
Fixup implementation for GDB and gdbserver of siginfo
types for x32 and 32bits inferior running on 64bits are merged.
It was added a simple way to add fields in the
siginfo structure for all architectures.
For i386/amd64 the dependency on the siginfo where
GDB/gdbserver for the usage and display was eliminated.
Now GDB descriptions of this type are enough for display
and usage.
Bound violation information can be seen in the last commit of
the series.
Pedro,
Thanks for your patch that has fixed evaluations while stopping,
but still not stopped. That has solved the issue also here
while evaluating the siginfo.
Best regards,
-Fred
Walfred Tedeschi (6):
Merges gdb and gdbserver implementation for siginfo.
Prepararion for new siginfo on Linux.
Use linux_get_siginfo_type_with_fields for x86.
Add bound related fields to the siginfo structure.
Adaptation of siginfo fixup for the new bnd fields.
Intel MPX bound violation handling.
