Re: dwarf2-frame.c question for maintainers
Here is a terse way to extract the least-significant end of the
register's value, regardless of endianness.
*** dwarf2-frame.c.~1.36.~ 2004-06-17 16:42:41.000000000 -0500
--- dwarf2-frame.c 2004-07-16 14:57:09.000000000 -0500
*************** read_reg (void *baton, int reg)
*** 214,219 ****
--- 214,222 ----
buf = (char *) alloca (register_size (gdbarch, regnum));
frame_unwind_register (next_frame, regnum, buf);
+ store_unsigned_integer
+ (buf, TYPE_LENGTH (builtin_type_void_data_ptr),
+ extract_unsigned_integer (buf, register_size (gdbarch, regnum)));
return extract_typed_address (buf, builtin_type_void_data_ptr);
}
Shouldn't that work? (Setting aside questions of whether it's
pleasing to extract, store, and then re-extract the value.)
