After that, I worked together with Michael to make this patch better. Now, I split the patch to 4 patches. 1. For gdbarch.sh 2. For record.c 3. For i386-linux 4. For amd64-linux Please post your comment to it. Thanks, Hui ^ permalink raw reply [flat|nested] 10+ messages in thread

Attached is a test case for it -- it will have a number of XFAILS without this patch, which will become PASSES with the patch.

Dumb mistake -- correct diagnosis.

Anyone knows if this is significant? I totally have no clue what the difference is.

Anyone knows if this is significant? Internally, all Tcl functions return a result code. It has been a while, but ISTR the codes are something like: OK, ERROR, CONTINUE, BREAK, RETURN. This allows execution control without the use of longjmp... the "return" function returns RETURN, continue returns CONTINUE, etc; then a surrounding loop function examines the code to decide what to do next. I presume, without looking, that the "source" command probably treats CONTINUE, BREAK, and RETURN equivalently. That is, there is likely no difference. "return" is clearer, though. I agree it would be good to have a test case cookbook, and guidelines. Tom ^ permalink raw reply [flat|nested] 10+ messages in thread
