binutils/gas/riscv: Add DWARF register numbers for CSRs
This commit gives DWARF register numbers to the RISC-V CSRs inline with the RISC-V ELF specification here: https://github.com/riscv/riscv-elf-psabi-doc/blob/master/riscv-elf.md The CSRs are defined being numbered from 4096 to 8191. This adds support to the assembler, required in order to reference CSRs in, for example .cfi directives. I have then extended dwarf.c in order to support printing CSR names in the dumped DWARF output. As the CSR name space is quite large and only sparsely populated, I have provided a new function to perform RISC-V DWARF register name lookup which uses a switch statement rather than the table base approach that other architectures use. Any CSR that does not have a known name will return a name based on 'csr%d' with the %d being replaced by the offset of the CSR from 4096. gas/ChangeLog: * config/tc-riscv.c (tc_riscv_regname_to_dw2regnum): Lookup CSR names too. * testsuite/gas/riscv/csr-dw-regnums.d: New file. * testsuite/gas/riscv/csr-dw-regnums.s: New file. binutils/ChangeLog: * dwarf.c (regname_internal_riscv): New function.
