[llvm-readobj] - Dump the ELF file type better. (details)
[RISCV] Add intrinsics for vfwmacc, vfwnmacc, vfwmsac, vfwnmsac instructions (details)

Commit bdef1f87aba656a64b34f76d2a6613b6e9299a03 by grimar [llvm-readobj] - Dump the ELF file type better. Currently llvm-readelf might print "OS Specific/Processor Specific/<unknown>" hint when dumping the ELF file type. The patch teaches llvm-readobj to do the same. This fixes https://bugs.llvm.org/show_bug.cgi?id=40868 I am removing `Object/elf-unknown-type.test` test because it is not in the right place, it is outdated and very limited. The `readobj/ELF/file-types.test` checks the functionality much better. Differential revision: https://reviews.llvm.org/D93689

Commit 6301871d06d6ea0195b5ea3b53288dcfe229557a by shihpo.hung [RISCV] Add intrinsics for vfwmacc, vfwnmacc, vfwmsac, vfwnmsac instructions This patch defines vfwmacc, vfwnmacc, vfwmsc, vfwnmsac intrinsics and lower to V instructions. We work with @rogfer01 from BSC to come out this patch.
