--- Comment #3 from John David Anglin <danglin at gcc dot gnu.org> ---
This patch introduces this difference in assembly code of genpreds.c:
- ldil L'-822083584,%r20
- depdi 0,0+32-1,32,%r20
- and %r22,%r20,%r20
- cmpb,*<> %r0,%r20,L$0361
- shladd,l %r31,3,%r28,%r20
+ ldil L'-822083584,%r21
+ and %r22,%r21,%r21
+ cmpb,*<> %r0,%r21,L$0361
+ shladd,l %r31,3,%r28,%r21
The depdi instruction clearing the most significant of register %r20
is no longer generated. The 32-bit immediate value loaded by the ldil
instruction is sign extended to 64 bits.
