This patch fixes various issues with vec_duplicate in the MVE patterns. Currently there are two patterns named *mve_mov<mode>. The second of these is really a vector duplicate rather than a move, so I've renamed it accordingly. As it stands, there are several issues with this pattern: 1. The MVE_types iterator has an entry for TImode, but vec_duplicate:TI is invalid. 2. The mode of the operand to vec_duplicate is SImode, but it should vary according to the vector mode iterator. 3. The second alternative of this pattern is bogus: it allows matching symbol_refs (the cause of the PR) and const_ints (which means that it matches (vec_duplicate (const_int ...)) which is non-canonical: such rtxes should be const_vectors instead and handled by the main vector move pattern). This patch fixes all of these issues, and removes the redundant *mve_vec_duplicate<mode> pattern. gcc/ChangeLog: PR target/99647 * config/arm/iterators.md (MVE_vecs): New. (V_elem): Also handle V2DF. * config/arm/mve.md (*mve_mov<mode>): Rename to ... (*mve_vdup<mode>): ... this. Remove second alternative since vec_duplicate of const_int is not canonical RTL, and we don't want to match symbol_refs. (*mve_vec_duplicate<mode>): Delete (pattern is redundant). gcc/testsuite/ChangeLog: PR target/99647 * gcc.c-torture/compile/pr99647.c: New test. |
