We able to handle V8HF to V8SF which does: ``` fcvtl v30.4s, v31.4h fcvtl2 v31.4s, v31.8h ``` But the first fcvtl is exactly what we want for V4HF->V4SF. ^ permalink raw reply [flat|nested] 3+ messages in thread

This allows the vectorizer to vectorize certain floating point widening operations for the aarch64 target. PR target/113880 PR target/113869 gcc/ChangeLog: * config/aarch64/aarch64-builtins.cc (VAR1): Remap float_extend_lo_ builtin codes to standard optab ones. * config/aarch64/aarch64-simd.md (aarch64_float_extend_lo_<Vwide>): Rename to... (extend<mode><Vwide>2): ... This. gcc/testsuite/ChangeLog: * gcc.target/aarch64/extend-vec.c: New test.
