This commit adds Zfhmin and Zhinxmin extensions (subsets of Zfh and Zhinx extensions, respectively). In the process supporting Zfhmin and Zhinxmin extension, this commit also changes how instructions are categorized considering Zfhmin, Zhinx and Zhinxmin extensions. Detailed changes, * From INSN_CLASS_ZFH to INSN_CLASS_ZFHMIN: flh, fsh, fmv.x.h and fmv.h.x. * From INSN_CLASS_ZFH to INSN_CLASS_ZFH_OR_ZHINX: fmv.h. * From INSN_CLASS_ZFH_OR_ZHINX to INSN_CLASS_ZFH_OR_ZHINX: fneg.h, fabs.h, fsgnj.h, fsgnjn.h, fsgnjx.h, fadd.h, fsub.h, fmul.h, fdiv.h, fsqrt.h, fmin.h, fmax.h, fmadd.h, fnmadd.h, fmsub.h, fnmsub.h, fcvt.w.h, fcvt.wu.h, fcvt.h.w, fcvt.h.wu, fcvt.l.h, fcvt.lu.h, fcvt.h.l, fcvt.h.lu, feq.h, flt.h, fle.h, fgt.h, fge.h, fclass.h. * From INSN_CLASS_ZFH_OR_ZHINX to INSN_CLASS_ZFHMIN_OR_ZHINXMIN: fcvt.s.h and fcvt.h.s. * From INSN_CLASS_D_AND_ZFH_INX to INSN_CLASS_ZFHMIN_AND_D: fcvt.d.h and fcvt.h.d. * From INSN_CLASS_Q_AND_ZFH_INX to INSN_CLASS_ZFHMIN_AND_Q: fcvt.q.h and fcvt.h.q. bfd/ChangeLog: * elfxx-riscv.c (riscv_implicit_subsets): Change implicit subsets. Zfh->Zicsr is not needed and Zfh->F is replaced with Zfh->Zfhmin and Zfhmin->F. Zhinx->Zicsr is not needed and Zhinx->Zfinx is replaced with Zhinx->Zhinxmin and Zhinxmin->Zfinx. (riscv_supported_std_z_ext): Added zfhmin and zhinxmin. (riscv_multi_subset_supports): Rewrite handling for new instruction classes. (riscv_multi_subset_supports_ext): Updated. (riscv_parse_check_conflicts): Change error message to include zfh and zfhmin extensions. gas/ChangeLog: * testsuite/gas/riscv/zfhmin-d-insn-class-fail.s: New complex error handling test. * testsuite/gas/riscv/zfhmin-d-insn-class-fail-1.d: Likewise. * testsuite/gas/riscv/zfhmin-d-insn-class-fail-1.l: Likewise. * testsuite/gas/riscv/zfhmin-d-insn-class-fail-2.d: Likewise. * testsuite/gas/riscv/zfhmin-d-insn-class-fail-2.l: Likewise. * testsuite/gas/riscv/zfhmin-d-insn-class-fail-3.d: Likewise. * testsuite/gas/riscv/zfhmin-d-insn-class-fail-3.l: Likewise. * testsuite/gas/riscv/zfhmin-d-insn-class-fail-4.d: Likewise. * testsuite/gas/riscv/zfhmin-d-insn-class-fail-4.l: Likewise. * testsuite/gas/riscv/zfhmin-d-insn-class-fail-5.d: Likewise. * testsuite/gas/riscv/zfhmin-d-insn-class-fail-5.l: Likewise. * testsuite/gas/riscv/zhinx.d: Renamed from fp-zhinx-insns.d and refactored. * testsuite/gas/riscv/zhinx.s: Likewise. include/ChangeLog: * opcode/riscv.h (enum riscv_insn_class): Removed INSN_CLASS_ZFH, INSN_CLASS_D_AND_ZFH_INX and INSN_CLASS_Q_AND_ZFH_INX. Added INSN_CLASS_ZFHMIN, INSN_CLASS_ZFHMIN_OR_ZHINXMIN, INSN_CLASS_ZFHMIN_AND_D and INSN_CLASS_ZFHMIN_AND_Q. opcodes/ChangeLog: * riscv-opc.c (riscv_opcodes): Change instruction classes for Zfh and Zfhmin instructions. Fix `fcvt.h.lu' instruction (two operand variant) mask.

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
