[gdb/target] Fix pretty-printer for MPX bnd registers
I'm seeing this failure:
...
(gdb) print /x $bnd0 = {0x10, 0x20}^M
$23 = {lbound = 0x10, ubound = 0x20}^M
(gdb) FAIL: gdb.arch/i386-mpx.exp: verify size for bnd0
...
The test expects a pretty printer to be actived printing 'size 17':
...
set test_string ".*\\\: size 17.*"
gdb_test "print /x \$bnd0 = {0x10, 0x20}" "$test_string" "verify size for bnd0"
...
but that doesn't happen.
The pretty printer is for the type of the $bnd0 register, which is created
here in i386_bnd_type:
...
t = arch_composite_type (gdbarch,
"__gdb_builtin_type_bound128", TYPE_CODE_STRUCT);
append_composite_type_field (t, "lbound", bt->builtin_data_ptr);
append_composite_type_field (t, "ubound", bt->builtin_data_ptr);
TYPE_NAME (t) = "builtin_type_bound128";
...
And the pretty-printer is registered here in
gdb/python/lib/gdb/printer/bound_registers.py:
...
gdb.printing.add_builtin_pretty_printer ('mpx_bound128',
'^__gdb_builtin_type_bound128',
MpxBound128Printer)
...
Fix the pretty printer by changing the regexp argument of
add_builtin_pretty_printer to match "builtin_type_bound128", the TYPE_NAME.
Tested on x86_64-linux.
gdb/ChangeLog:
2019-10-09 Tom de Vries <tdevries@suse.de>
* python/lib/gdb/printer/bound_registers.py: Use
'^builtin_type_bound128' as regexp argument for
add_builtin_pretty_printer.
