Subject: .init stub creation doesn't need a jmp + .align to reach a branch target,
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=794f0c6802f4f4b7751d11683c2c9cd3ce2e237a;p=openbsd

.init stub creation doesn't need a jmp + .align to reach a branch target,
just fall into the code.  The .align created a FILL zone in the .init section,
which on i386 was filled with a NOP-sled, something we want to get away
from.
discussed with kettenis and tom
