I think that watchpoint-related code in GDB improved _a lot_ since v4.18, but I'm not sure how relevant these improvements are for the S/390 port. The watchpoint support is certainly much better for x86-based targets, one of which I maintain. If you can describe in more detail what problems did you see in v4.18, it will be possible to tell you which problems are now resolved. >From DJBARROW@de.ibm.com Fri Aug 25 04:58:00 2000 From: DJBARROW@de.ibm.com To: Eli Zaretskii Cc: gdb-patches@sourceware.cygnus.com, nickc@cygnus.com, Michael Snyder Subject: Re: [PRELIMINARY]: Patch to add bfd support for IBM s390 Date: Fri, 25 Aug 2000 04:58:00 -0000 Message-id: X-SW-Source: 2000-08/msg00313.html Content-length: 706 If this code has improved my kludges are probably obselete. To be honest it was a long time ago, it was primarily to do with watchpoints set up in hw being inconsistent with what info watchpoints said was active. e.g. The watchpoint code cleaned the hardware breakpoints in the next run while info watchpoints still reported watchpoints active ( this kind of stuff ), unfortunately I cant remember exactly just cast asparagus. I'll do some testing over the next few days & if it still looks unhealthy I'll start complaining. D.J.
