sparc/leon: add support for partial write psr instruction
Partial write %PSR (PWRPSR) is a SPARC V8e option that allows the WRPSR instruction to only affect the %PSR.ET field. When available it is enabled by setting the rd field of the WRPSR instruction to a value other than 0. For Leon processors with support for partial write %PSR (currently GR740 and GR716) the rd value must be 1. opcodes/ChangeLog: 2018-08-29 Martin Aberg <maberg@gaisler.com> * sparc-opc.c (sparc_opcodes): Add Leon specific partial write psr (PWRPSR) instruction. gas/ChangeLog: 2018-08-29 Daniel Cederman <cederman@gaisler.com> * testsuite/gas/sparc/leon.d: New test. * testsuite/gas/sparc/leon.s: New test. * testsuite/gas/sparc/sparc.exp: Execute the pwrpsr test.
