Re: [Jikesrvm-core] proposed change to jconfigure/jbuild

After some thinking and a discussion with Dave, I've decided to leave OPT_ARGS as is, but to add a new option DEBUG_ARGS which will be picked up by jbuild.linkImage Turns out that some of the special configuration files rely on the OPT_ARGS being picked up at the time of the jconfigure. So, I don't want to change jconfigure's behaviour. There will still be two ways to change behaviour at the time of the jbuild command. Either set DEBUG_ARGS or edit the jbuild.linkImage script.

To: jik...@ww... cc: Subject: [Jikesrvm-core] proposed change to jconfigure/jbuild Currently there is an environment variable OPT_ARGS that is read by jconfigure. jconfigure writes the value currently set into the script jbuild.linkImage. If you are trying to debug a problem that shows up at bootImage build time then you may want to adjust the options that are used as you run repeated "jbuild" commands. With the current system you need to rerun jconfigure to pick up the new OPT_ARGS or change jbuild.linkImage. I propose to change this system, to instead have jbuild.linkImage pick up the current value of the OPT_ARGS environment variable. Thus, in korn shell you can run OPT_ARGS="-X:bc:high=true -X:bc:method_to_print=A.method" jbuild on one run and on the next specify OPT_ARGS="-X:bc:low=true -X:bc:method_to_print=A.method" jbuild without having to run jconfigure a second time. Please let me know if you have any concerns with this change. Janice ----------------------------------------------------------------------------- Janice C. Shepherd ja...@wa... (or ja...@us...)
