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.
* Makefile.in (vr4320.igen) : Added.
* configure.in (mips64vr4320-*-*): Added.
* configure : Rebuilt.
* mips.igen : Correct the bfd-names in the mips-ISA model entries.
Add the vr4320 model entry and mark the vr4320 insn as necessary.
* sky-vu1.c (vu1_io_write_register_window): Make CIA (pc) write
effective by updating more registers.
* sky-libvpe.c: Updated to match earlier VU state-change code.
* sky-vpe.h: Removed unused globals from declarations.
PKE tests run identically on SPARC/Solaris and x86/Linux.
* sky-pke.c (pke_io_{read,write}_buffer): Endianness fixes aka
"E-fixes" in register and FIFO read/writes.
(pke_code_{pkemscalf,pkemscal}): E-fixes in VU CIA setting.
(pke_code_{mpg,unpack}): E-fixes in VU memory & tracking updates.
(pke_code_direct): E-fixes in GPUIF FIFO stuffing.
* sky-pke.h (PKE_MEM_WRITE): E-fixes in trace file writing.
* sky-vu0.c (vu0_attach): Allocate micro/data memory with zalloc
to guarantee sufficient (16-byte) alignment.
* sky-vu1.c (vu1_attach): Ditto.
(vu1_io_read_register_window): *PARTIAL* E-fixes in register accesses.
* sky-libvpe.c (gif_write): E-fixes in GPUIF FIFO stuffing.
* sky-gpuif.c (gif_io_{read,write}_buffer): E-fixes in
register and FIFO read/writes.
* sky-dma.c (do_dma_transfer_tag): E-fixes in tag reading.
mechanism is starting to subside.
* sky-pke.h (PKE_FLAG_INT_NOLOOP): Added device flag to indicate
presence of stalled & interrupted PKEcode.
* sky-pke.c (pke_issue): Added PKEcode interrupt bit handling.
(pke_flip_dbf): Changed double-buffering logic to match SCEI
clarification.
(pke_code_*): Added interrupt bit stalling clause.
(pke_code_pkems*): Added ITOP/ITOPS transmission code.
(pke_code_unpack): Added more careful logic for processing
overflows of VU data memory addresses.
