Allow vector_length clauses to accept values larger than warp size. Note that this does not enable setting vector_length to values larger than warp size using -fopenacc-dim. 2019-01-12 Tom de Vries <tdevries@suse.de> * config/nvptx/nvptx.c (nvptx_goacc_validate_dims): Take larger vector lengths into account. * testsuite/libgomp.oacc-c-c++-common/vector-length-128-1.c: Expect vector length to be 128. * testsuite/libgomp.oacc-c-c++-common/parallel-dims.c: Expect vector length 2097152 to be reduced to 1024 instead of 32.
