I'm in the process of porting gdb to sgi 4d machines, based on a gdb port to DECstation mips machines. It seems to basically work, but unpredictably flakes out with messages such as "debugged process doesn't exist" or "unable to set break points". Oh well. My question has to do with ptrace: Directive 1 (PTRC_RD_I) reads data from I space, 2 (PTRC_RD_U) reads from D space. Does it matter if you read data from data space using PTRC_RD_I?
