No it doesn't. See the gymnastics that Bill Paul had to do recently in
the iee80211 code to get around the insane inlining that gcc does with

that there is very strong evidence that it produces code that is
incompatible with the restrictions inherent to the kernel, mainly that
stack space is not infinite.
I wonder how this is being done elsewhere, on NetBSD, everything is
built with -O2 and has been for several years afair.
Not that I care much about it but apparently it doesn't seem to be
such a big problem everywhere?
mkb.
I'm sure that it's highly dependent on the version of gcc in use and the
other -f flags that are passed to it, neither of which I'm familiar with
in NetBSD.
