Gdb command watch issue hardware requests

[Liu Yu-B13201]

Hi guys,

I am now developing in gdb remote mode.
I heard from someone that 'hbreak' and 'watch' should make the gdb frontend issue requests for hardware break/watchpoints.
(gdb >= 6.8 for hardware breakpoint over remote connections)

I checked that 'hbreak' indeed issue hardware breakpoint request but 'watch' still use software breakpoint and single step.
The toolchain version I used is gcc-4.3.74-eglibc-2.8.74-5 in which gdb version is 6.8.50.20080821-cvs. Does it not enough to support hardware assistant watch?

Does anyone know something about this?
