gdb/rs6000: Read backchain as unsigned.
Previously, backchain was read as a signed quantity, resulting in
addresses like 0xfffffffffffeded0 instead of 0xfffeded0 returned by
unwinder on 32-bit powerpc. While normally such addresses are masked
off, this causes problems for tracepoints, since 0xfffffffffffeded0
is considered unavailable.
Fixes a test failure in gdb.trace/entry-values.exp.
gdb/ChangeLog:
* corefile.c (safe_read_memory_unsigned_integer): New function.
* gdbcore.h (safe_read_memory_unsigned_integer): New prototype.
* rs6000-tdep.c (rs6000_frame_cache): Read backchain as unsigned.
