This patch resolves PR target/102785 where my recent patch to constant fold saturating addition/subtraction exposed a latent bug in the bfin backend. The patterns used for blackfin's V2HI ssaddsub and sssubadd instructions had the indices/operations swapped. This was harmless until we started evaluating these expressions at compile-time, when the mismatch was caught by the testsuite. 2021-10-19 Roger Sayle <ro...@nextmovesoftware.com> gcc/ChangeLog PR target/102785 * config/bfin/bfin.md (addsubv2hi3, subaddv2hi3, ssaddsubv2hi3, sssubaddv2hi3): Swap the order of operators in vec_concat.
