Subject: Re: [4.6 regression] Revision 162270 failed
to bootstrap
The exception is caused by get_bb_copy returning NULL. However, get_bb_copy
is not miscompiled.
The change to function.c changes various copies to extracts for
zero/sign extension. These might cause a functional difference.
For example,
- copy %r26,%r23
+ extrd,u %r26,63,32,%r23
It won't be easy to substitute functions in the .s file because
there are a many label changes.
