Hello, This is applicable to mips targets. When using info registers $N command, gdb_assert will be triggered if N falls in the raw register number area. However, this is counter-intuitive. The change simply maps raw-register number to pseudo register number and continues as before. ------------------------------------- Example: current situation (gdb) info registers $1 ../../gdb/mips-tdep.c:4307: internal-error: mips_print_registers_info: Assertion `regnum >= gdbarch_num_regs (current_gdbarch)' failed. Example: with the patch (gdb) info registers $1 at: 0x8020000 -------------------------------------- Thanks, Aleksandar Ristovski QNX Software Systems
