# ij's default AMG solver (and ij_assembly, struct, sstruct, etc.) link
# against math/openblas, whose OpenMP-threaded BLAS kernels crash the base
# system's libomp on aarch64 with "Too many args to microtask" (a fixed
# argument-count limit in libomp's AArch64 microtask-invocation trampoline).
# This is an OpenBLAS/libomp/architecture issue, not a bug in hypre, and is
# unrelated to this port update. "ij -solver 2" (DS-PCG, no AMG) exercises
# IJ matrix/vector assembly and the solve loop without hitting that code
# path, so it is used here as the test.
# ij_mv and maxwell_unscaled no longer exist as test binaries as of 3.2.0;
# upstream replaced them with a new ctest-registered suite
# (test_ij_solvers, test_struct_solvers, ...) that is not run here because
# it invokes shell scripts with a hardcoded #!/bin/bash shebang, a path that
# does not exist on FreeBSD (bash is installed under ${LOCALBASE}/bin).

# tests as of 3.2.0: ij -solver 2 (DS-PCG) completes successfully
