Dear Simon,
Thanks for your reply. I went ahead and completed the build of gbd-9.1,
which had been the original plan. With the gdb-9.1 executable, I re-ran
it against the llvm-tblgen binary and its core dump, with the same
result as in gdb-8.3. So this is progress of a sort, I suppose.
Taking now the gdb-9.1 and loading gcc9 into the debugger, then "show
architecture" yields "The target architecture is set automatically
(currently sparc:v9)". The system I am using is based on the 500-MHz
UltraSPARC IIe processor. So maybe this setting, sparc:v9, is wrong for
this platform?
Best wishes,
Chris.
