opcodes,gas: adjust sparc insns and make GAS aware of it
This patch marks the SPARC instructions in the opcodes table with their
proper opcode architectures, and makes the assembler aware of them.
This allows the assembler to properly realize when a new instruction
needs a higher architecture (after v9b) and to react accordingly
emitting an error message or bumping the architecture.
It also expands architecture mismatch tests to cover architectures
higher than v9b, and fixes a couple of minor bugs in the GAS testsuite.
opcodes/ChangeLog:
2016-06-17 Jose E. Marchesi <jose.marchesi@oracle.com>
* sparc-opc.c (sparc_opcodes): Adjust instructions opcode
architecture according to the hardware capabilities they require.
(sparc_priv_regs): New table.
(sparc_hpriv_regs): Likewise.
(sparc_asr_regs): Likewise.
(v9anotv9m): Define.
gas/ChangeLog:
2016-06-17 Jose E. Marchesi <jose.marchesi@oracle.com>
* config/tc-sparc.c (sparc_arch_table): adjust the GAS
architectures to use the right opcode architecture.
(sparc_md_end): Handle v9{c,d,e,v,m}.
(sparc_ip): Fix some comments.
* testsuite/gas/sparc/ldx_efsr.d: Fix the architecture of this
instruction, which is v9d.
* testsuite/gas/sparc/mwait.s: Remove the `rd %mwait,%g1'
instruction from the test, as %mwait is not readable.
* testsuite/gas/sparc/mwait.d: Likewise.
* testsuite/gas/sparc/mism-1.s: Expand to check v9b and v9e
mismatch architecture errors.
* testsuite/gas/sparc/mism-2.s: New file.
