Nicolas Brunie	41c31ce427	[#2273 ][bulknormdot] fixing spurious invalid flag in bulk_norm_dot_no_mult Bulk normalized dot product is expected to raise the invalid flag if two products with infinite values and opposite signs are added. Spike function failed to consider the second operand of a product when determining whether the product had infinite value or not, and missed the exclusion of NaN and zero from this case. The zero case is quiet, because it happens for inf * zero which is expected to raise the invalid flag. The qNaN case is not quiet and can cause the apparition of a spurious invalid flag when none were expected.	1 month ago

Andrew Waterman	ea29ce276c	Make sure VS is set on fault-only-first loads in all cases We weren't setting it in the case that an exception was detected on element 0, which is technically OK since no state changed, but is inconsistent with how we handle regular vector loads.	3 months ago
Andrew Waterman	17682e173d	Make all vector ALU instructions invoke VECTOR_END, dirtying VS dirty_vs_state is therefore no longer needed at the top in require_vector. Furthermore, the vstart write in VECTOR_END dirties VS, so dirty_vs_state is not needed.	4 months ago
