* sky-pke.h (pke_fifo*): Exported these formerly private functions.
(pke_device): Added FIFO cache fields.
* sky-pke.c (pke_fifo_reset): New function for GPUIF client -
clear FIFO contents.
(pke_pcrel_fifo): Added caching facility to prevent O(n^2) cost for
searching for consecutive operand words.
* sky-libvpe.c (MEM, uMEM): New/changed macros that perform modulo
calculations to handle out-of-range VU memory addresses.
(*): Replaced many previous uses of MEM[] and state->uMEM[] with
calls to above macros.
* sky-vu.h (struct VectorUnitState): Added qw/dw size fields for
MEM/uMEM buffers, for overflow prevention. Renamed MEM/uMEM fields
to catch all their prior users.
* sky-vu0.c (vu0_attach): Manually align MEM0/MEM1 buffers to force
16-byte alignment. (zalloc is not enough.)
* sky-vu1.c (vu1_attach): Ditto.
(init_vu): Store buffer sizes from allocation into VectorUnitState.
* sky-gpuif.h (GifPath): Use a pke_fifo strucf instead of
temporary fixed-size array for flexible FIFO sizing.
* sky-gpuif.c (SKY_GPU2_REFRESH): This is now an integer value to be
used as a modulus for periodic refresh.
(refresh): New function to send GPU2 refresh code periodically.
(*): Use pke_fifo calls to en/dequeue GPUIF tags & operands.
* sky-pke.h (struct pke_device): Added fields to allow caching of
results from recent FIFO searches.
unsigned types.
Specify size of r5900 FSR using 32 bit unsigned type.
Correctly format mips registers when some are not 64 bits in size
Check that REGISTER_{RAW,VIRTUAL}_SIZE are consistent when the target
specifies that no conversion is needed when moving from one to the
other.
* scripttempl/pe.sc: The Cygwin32 library uses a .data$nocopy
section to avoid copying certain data on fork. The linker used to
include this between __data_start__ and __data_end__, but that
breaks building the cygwin32 dll. The fix is to rename the
section ".data_cygwin_nocopy" and explictly include it after
__data_end__.
"name.completer" where only the name is actually in the opcode
table. Allow various operands for base register in load/store
instructions. Handle various new argument characters for the
cop2/vu0 co-processor.
* mips-opc.c: Include vu0.h.
* mips-dis.c (print_insn_arg): Handle new args 0-9, +, -, %, K, &,
J, Q, X, and U.
(print_insn_mips): Do not emit a tab after an instruction if the
first arg is an instruction completer (&). If the next arg is an
escape character (%), then print the next arg verbatim.
* Makefile.am (mips-opc.lo): Depend on vu0.h
* minsyms.c (compare_minimal_symbols): If addresses are identical,
then compare on names. Sorted list should have symbols with
identical addresses AND names adjacent, so dups can be discarded.
the stand-alone executable.
[in ChangeLog.sky:]
* sky-gpuif.c (call_gs): Call properly into GPU2 library if
configured --with-sim-gpu2. Use SKY_GPU2_REFRESH symbol as
placeholder for future GPU2-refresh policy.
[in ChangeLog:]
* Makefile.in (MIPS_EXTRA_LIBS, SIM_EXTRA_LIBS): Added
configurable settings for stand-alone simulator.
start-sanitize-sky
* configure.in: Added --with-sim-gpu2 option to specify path of
sky GPU2 library. Triggers -DSKY_GPU2 for sky-gpuif.c, and
links/compiles stand-alone simulator with this library.
* interp.c (MEM_SIZE): Increased default sky memory size to 16MB.
end-sanitize-sky
* configure.in: Added X11 search, just in case.
* configure: Regenerated.
will ignore this until next SCEI clarification.
* tsv308_1.trc: Fixed test case as per SCEI email.
* tsv316_1.trc: Ditto.
* tsv408_1.trc: Same.
* tsv416_1.trc: Again.
* t-pke3.trc: Added more padding to one VU test to widen timing race.
* Make-common.in (dv-sockser.o): Add rule for.
* aclocal.m4: Check for fcntl.h.
* config.h: Add HAVE_FCNTL_H.
* sim-break.c (remove_breakpoint): Fix thinko.
* sim-hload.c (sim_load): Provide default value of SIM_HANDLES_LMA.
Use SIM_HANDLES_LMA for lma_p arg to sim_load_file.
of PKE, some old test cases had to be modified. There are suspected bugs
in the SCEI test cases too, so "make check" does not run cleanly at present.
* tss*.trc: New files, generated by perl script from
SCEI "test0" bucket.
* tsv*.trc: New files, generated by perl script from SCEI "test0"
bucket. Note that tsv432_0 may obsolete t-pke1.
* Makefile.in (TESTS): Run new scripts.
(check): Bulldoze through failing test cases with "make -k" until
SCEI fixes some of them.
(.run.ok): Increased run-time limit since some test runs can take
several seconds.
effectively full. The code is believed to be functionally complete now.
Some code cleanup is included at no extra charge in this version.
Fri Mar 13 20:21:57 1998 Frank Ch. Eigler <fche@cygnus.com>
* sky-vu1.c: (dump_mem): Commented out function to satiate
warning-ful compilation.
