opcodes,gas: sparc: fix rdasr,wrasr,rdpr,wrpr,rdhpr,wrhpr insns.

Browse Source 
This patch fixes and expands the definition of the read/write
instructions for ancillary-state, privileged and hyperprivileged
registers in opcodes.

It also adds support for three new v9m hyperprivileged registers:
%hmcdper, %hmcddfr and %hva_mask_nz.

Finally, the patch expands existing tests (and adds several new ones) in
order to cover all the read/write instructions in all its variants.

opcodes/ChangeLog:

2016-06-17  Jose E. Marchesi  <jose.marchesi@oracle.com>

	* sparc-opc.c (rdasr): New macro.
	(wrasr): Likewise.
	(rdpr): Likewise.
	(wrpr): Likewise.
	(rdhpr): Likewise.
	(wrhpr): Likewise.
	(sparc_opcodes): Use the macros above to fix and expand the
	definition of read/write instructions from/to
	asr/privileged/hyperprivileged instructions.
	* sparc-dis.c (v9_hpriv_reg_names): Add %hmcdper, %hmcddfr and
	%hva_mask_nz.  Prefer softint_set and softint_clear over
	set_softint and clear_softint.
	(print_insn_sparc): Support %ver in Rd.

gas/ChangeLog:

2016-06-17  Jose E. Marchesi  <jose.marchesi@oracle.com>

	* config/tc-sparc.c (hpriv_reg_table): Add registers %hmcdper,
	%hmcddfr and %hva_mask_nz.
	(sparc_ip): New handling of asr/privileged/hyperprivileged
	registers, adapted to the new form of the sparc opcodes table.
	* testsuite/gas/sparc/rdasr.s: New file.
	* testsuite/gas/sparc/rdasr.d: Likewise.
	* testsuite/gas/sparc/wrasr.s: Likewise.
	* testsuite/gas/sparc/wrasr.d: Likewise.
	* testsuite/gas/sparc/sparc.exp (sparc_elf_setup): Add rdasr and
	wrasr tests.
	* testsuite/gas/sparc/rdpr.d: Use -Av9m, as some privileged
	registers require it.
	* testsuite/gas/sparc/wrpr.s: Complete to cover all privileged
	registers and write instruction modalities.
	* testsuite/gas/sparc/wrpr.d: Likewise.
	* testsuite/gas/sparc/rdhpr.s: Likewise for hyperprivileged
	registers.
	* testsuite/gas/sparc/rdhpr.d: Likewise.
	* testsuite/gas/sparc/wrhpr.s: Likewise.
	* testsuite/gas/sparc/wrhpr.d: Likewise.
