Description

« Hide

By turning off null checks and bounds checks we can reduce the amount of code in the boot image slightly.

I have attached two patches. One to fix the nobounds/nonullcheck options that failed for me due to missing guards, and a second to turn off the checks within uninterruptible code.

My very quick test for production indicated we could save a little over 1MB.

Is there any reason these patches haven't been applied?

It's not correct to do so until the pragma uninterruptible/unpreemtpible mess is cleaned up. There's too much sloppy use of the NoWarn backdoors.

Ugh, can we create some issues to get this cleaned up. I noticed there weren't any in JIRA or even on sourceforge.
