Description Teresa Thomas 2008-05-05 19:19:57 UTC
IA32WatchpointFunctions.setWatchpoint handles 1, 2 or 4 bytes ranges only. 

[type double on IA32 = 8 bytes]
Comment 1 Phil Muldoon 2008-05-05 21:04:03 UTC
Unfortunately one watchpoint = max of 4 bytes on IA32. I guess the thing to do
here in the client would be if length > 4 set two+ plus watchpoints. In the case
of double, one for the top half, one for the bottom half. Likely this would
trigger both watchpoints one write, but the high level would have to deal with
this interpretation by looking at its own length data.
