variables optimized out

[robbinson defau]

Hi all,

Im debugging some issues in the kernel and as the kernel is compiled by
default with -O2, a lot of variables are optimized out. So i made changes
to make.conf (CFLAGS and COPTFLAGS).\

All builds fine, but I get the weirdest of panics that most certainly not
happen with -O2. So it's likely i'm doing something wrong. What would be
the correct way to be able to debug the kernel and have it build such that
locals and function arguments are not optimized out?

Thanks in advance,
