Subject: register type as signed or unsigned?
Date: Tue, 10 Oct 2006 08:37:00 -0000 [thread overview]
Message-ID: <OF038E4AEA.A0A9C5E8-ON48257203.002DDCAC-48257203.002F6D81@sunnorth.com.cn> (raw)
hello all,
I am porting GDB to a new target.
I am not aware of the meaning of register type.
You can do as follows:
set_gdbarch_register_type (gdbarch, builtin_type_int32);
or
set_gdbarch_register_type (gdbarch, builtin_type_uint32);
What is the real difference between the two situation?
Why should GDB specify the register type as signed or unsigned?
Dose it mean the former must use regcache_cooked_read_signed() and the
latter must use
regcache_cooked_read_unsigned()?
Best regards
Ligang
