Hello, I'm trying to get soft-fp64 working with my experimental r600-nir backend, and thanks to Dave's contribution it is already tied in, some instructions are not yet supported by the backend, but when running the piglits I have already 24 tests passing. However, there are also 1099 test crashing, and skimming over the results this is mostly because of validation erros in nir_lower_doubles called with nir_lower_fp64_full_software. For instance, in fs-fract-dvec4 I get something like
decl_var INTERP_MODE_NONE dvec4 p ... vec1 32 ssa_0 = deref_var &p (function dvec4) ... call __fadd64 ssa_77, ssa_78, ssa_79 vec1 64 ssa_80 = intrinsic load_deref (ssa_77) (0) /* access=0 */intrinsic store_deref (ssa_0, ssa_80) (15, 0) /* wrmask=xyzw */ /* access=0 */ error: src->ssa->num_components == num_components (../../../mesa/src/compiler/nir/nir_validate.c:206) ... with (src->ssa->num_components == 1) and (num_components == 4). i.e. a function returns a single value, but the target where to store it is a vector with four elements. I have no idea whether this is something triggered by the compile options I defined for nir, or whether this is independed from this, so any idea how to quell this would be very welcome. Many thanks, Gert _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
