[SPARC] Prevent -mfix-ut699 from generating b2bst errata sequences
The sequence
st
fdivd / fsqrtd
std
was generated in some cases with -mfix-ut699 when there was
a st before the div/sqrt. This sequence could trigger the b2bst errata.
Now the following safe sequence is generated instead:
st
nop
fdivd / fsqrtd
std

* config/sparc/sparc.md (divdf3_fix): Add NOP and adjust length
to prevent b2bst errata sequence.
(sqrtdf2_fix): Likewise.
