aarch64: Introduce new unspecs for smax/smin
Introduce two new unspecs, UNSPEC_COND_SMAX and UNSPEC_COND_SMIN,
corresponding to rtl operators smax and smin. UNSPEC_COND_SMAX is used
to generate fmaxnm instruction and UNSPEC_COND_SMIN is used to generate
fminnm instruction.
With these new unspecs, we can generate SVE2 max/min instructions using
existing generic unpredicated and predicated instruction patterns that
use optab attribute. Thus, we have removed specialised instruction
patterns for max/min instructions that were using
SVE_COND_FP_MAXMIN_PUBLIC iterator.
No new test cases as the existing test cases should be enough to test
this refactoring.
gcc/ChangeLog:
* config/aarch64/aarch64-sve.md
(<fmaxmin><mode>3): Remove this instruction pattern.
(cond_<fmaxmin><mode>): Remove this instruction pattern.
* config/aarch64/iterators.md: New unspecs and changes to
iterators and attrs to use the new unspecs
