Description

With a giant sed and some small code changes, we can replace most -Wno-uninitialized
with -Wno-maybe-uninitialized across the whole source base, when using GCC7 and up.

History

#1

Updated by John Levon 11 days ago

Changes that aren't just from the sedall:

 - usr/src/cmd/zlogin/ needed a small change (no bug)
 - usr/src/lib/gss_mechs/mech_krb5/krb5/krb/gic_pwd.c was broken
 - usr/src/lib/libc/inc/thr_inlines.h - GCC complains as we state that '__value' in
   set_lock_byte() is read-write. But in fact we always write first. Rather than
   try to change the +d to d, we'll just set to zero
 - __class_quadruple hack
 - Makefile.uts has the new flag
 - usr/src/uts/common/vm/vm_pagelist.c and related, harmless fix
 - kept -Wno-uninitialized for ucblib
