154 Added timing checks on the busy and valid signals: either one of the two is
valid, or the whole is idle.
dgisselq 2297d 06h /zipcpu/
153 Adds internal link functionality to the specification document format. dgisselq 2297d 06h /zipcpu/
152 Updated to match the new/updated multiply instructions. Of course, this is
still hand optimized and not compiled--so it's not really a true and proper
test (yet), but ... it's what I have.
dgisselq 2330d 04h /zipcpu/
151 Minor formatting change. dgisselq 2330d 04h /zipcpu/
150 Minor changes. dgisselq 2330d 05h /zipcpu/
149 Updated the Makefile documentation and the all target. dgisselq 2330d 05h /zipcpu/
148 Minor changes to get LONG_MPY working, and adjust the documentation. dgisselq 2330d 05h /zipcpu/
147 Cleans up div_tb a bit, causing it to write SUCCESS out if successful and
abort if not.
dgisselq 2330d 05h /zipcpu/
146 Fixes a problem where the assembler complained the compiler was trying to
move .org backwards. This is now fixed.
dgisselq 2330d 05h /zipcpu/
145 This fixes the pipelined memory problem that was introduced a while back to
fix ... pipelined memory conflicts. This appears to maintain the success
of the fix, while recovering the pipeline memory performance that was had
before.
dgisselq 2330d 05h /zipcpu/
144 Makes the auto-reload capability a configuration option, and fills out the
reset so that it is properly implemented.
dgisselq 2330d 05h /zipcpu/
143 This section belatedly adjusts the zasm assembler so that it can handle
the LONG_MPY changes that have taken place. However, the test.S assembler
test script is still not properly testing the multiplies--at least it will
succeed on everything else.
dgisselq 2330d 05h /zipcpu/
142 Bug fix--fixes some problems with conditional execution, as well as removing
an unnecessary peephole optimization.
dgisselq 2331d 06h /zipcpu/
141 Fixes two bugs: one causing merged strings in the read only string section to
be referenced at the wrong address, and the second which caused the assembler
to fail at SYMBOL-OFFSET references.
dgisselq 2331d 06h /zipcpu/
140 Minor changes, but fixes build of zippy_tb.cpp. dgisselq 2333d 18h /zipcpu/
139 Changes necessary to document the changed instruction set: LDIHI became MPY,
and MPYU and MPYS became MPYUHI and MPYSHI respectively. See the specification
for more details.
dgisselq 2336d 15h /zipcpu/
138 This updates the CPU multiply instruction into a set of three instructions.
MPY is a 32x32-bit multiply instruction, returning the low 32-bit result,
MPYUHI returns the upper 32-bits assuming the result was unsigned and MPYSHI
returns the upper 32-bits assuming the result was signed.
dgisselq 2336d 16h /zipcpu/
137 This should (again) fix the bug of trying to build optest.cpp. dgisselq 2350d 09h /zipcpu/
136 Oops --- missed a couple HOST_WIDE_INT values in a printf. This casts them
to (long), so that we can work on both PC's and ARMs.
dgisselq 2350d 10h /zipcpu/
135 Replaced all occurrences of INTVAL(...) on printf lines with (long)INTVAL(...).
This should fix the problems zip-gcc was having while running on the ARM.
