Hi Uwe,
to go further with mingw support, apply the attached patch and recompile
the debugger dir with _WE_SUPPORT_THE_STAB_TYPES_USED_BY_MINGW_TOO defined
this let at least symbol loading from gdis.exe (which current code doesn't
allow :-( ), I was able to set a bp on WinMain, continue to it, and then
single step... and then got a segv... (which doesn't appear when running
without the debugger - strange)
there's still some issue with global variables that
will not be correctly handled (there's some comments and quirkies
in debugger/stabs.c regarding ELF global variables (which mingw seems
to handle slightly differently - look for N_GSYM in DEBUG_ParseStabs
and at DEBUG_ProcessElfSymtab))
I don't intend to add this patch (without the #ifdef protection) to the CVS
tree, because there's also quite some work to be done on symbol loading vs
module loading (current code still assumes debugger and debuggee are in same
address space), and still peruses the process PDB (with direct memory access)
which shouldn't be.
