* Numerous changes & small bug fixes in PKE sim code and test suite.
for sim/testsuite/sky: * t-pke4.run: Removed test, since it succeeds yet returns a non-zero exit code. * Makefile.in (RUNOPTS): Removed --memory-size flag, made unnecessary by sim/mips/interp.c changes. (TESTS): Removed t-pke4.ok target. * t-pke3.trc: Classified tests with [---] indicators, to match items up with entries documented in testplan.sgml. Added numerous additional tests. They assert behavior that assumes certain favorable answers to PKE question set #6 to SCEI. * t-pke1.trc: Added some [---] indicators. for sim/mips: * sky-pke.c (pke_issue): Revamped interrupt & stall code. Assume that ER1/ER0/PIS bits are only set if not masked by ERR bits. Signal PIS only if unmasked. (pke_code_error): Signal ER1 only if unmasked. (pke_pc_fifo): Signal ER0 only if unmasked. (pke_code_unpack): Round up num_operands for last operand's partial-word. Factor out "R" bit handling for better coverage analysis. Fill upper words of a quadword with zeroes for Vn_m UNPACK with n < 4. * sky-device.c (device_error): Made function accept varargs. * sky-device.h (device_error): Changed declaration to match. * interp.c (sim_open): Made 0x0000 area memory be an alias of the K0/K1 segments. Sanitized code.
