- gdb-4.6, "configure decstation"
-
- Couple of minor bugs in printing out the registers for the mips
- architecture. raw_buffer is not large enough so the stack was being
- stomped in mips_print_register(), and REGISTER_VIRTUAL_TYPE() did not
- return the correct type for the floating-point registers.
-
- It's not clear whether the odd-numbered floating-point registers
- should be printed as floating-point numbers or not since they cannot
- be used for floating-point operations--they are only used for loading
- and storing. Beats me, so I left it alone.
