Handle 64bit breakpoints of WOW64 processes as SIGINT
When a WOW64 process triggers a breakpoint exception in 64bit code (which
happens when a 64bit gdb calls DebugBreakProcess for a 32bit target),
gdb ignores the breakpoint (because Wow64GetThreadContext can only report
the pc of 32bit code, and there is not int3 at this location).
But if these 64bit breakpoint exceptions are handled as SIGINT, gdb
doesn't check for int3, and always stops the target.
gdb/ChangeLog:
2020-09-23 Hannes Domani <ssbssa@yahoo.de>
* nat/windows-nat.c (handle_exception): Handle 64bit breakpoints
in WOW64 processes as SIGINT.
* nat/windows-nat.h: Make wow64_process a shared variable.
* windows-nat.c: Remove static wow64_process variable.
gdbserver/ChangeLog:
2020-09-23 Hannes Domani <ssbssa@yahoo.de>
* win32-low.cc: Remove local wow64_process variable.
* win32-low.h: Remove local wow64_process variable.
