Hi, In the course of verifying an out-of-tree RISC-V target that has a vendor extension providing hardware support for vector operations on pairs of single floating-point values (similar to MIPS paired-single or Power SPE vector types) I have come across a couple of tests that fail just because they expect GCC to produce code this particular hardware does not support. Therefore I have created this small patch series, which marks the features required for the test cases to be relevant, which makes them unsupported for the hardware concerned. For further details see individual change descriptions.
This patch series has been verified with an `x86_64-linux-gnu' native configuration. I could verify it with MIPS paired-single hw sometime, but I'm not currently set up for it and I think the changes are obvious enough regardless. OK to apply? As testsuite fixes I think the changes also qualify for backporting to active release branches. Maciej
