166 Bugfix version. This fixes a problem whereby function addresses with offsets
were not properly calculated, together with properly setting up pcrelative
offsets when using the move function together with a label.		 dgisselq 2833d 20h /zipcpu
165 Added a test to make certain that the arithmetic right shift was properly
propagating the high order bit. (The test works under verilator, but didn't
initially work in Xilinx -- thus a difference between the two.)		 dgisselq 2833d 20h /zipcpu
164 Updated with inputs from Hellwig Geisse regarding the details of the ECO32
CPU.		 dgisselq 2841d 22h /zipcpu
163 Trimmed OR1K instruction set down from 219 instructions, to the minimum number
of 48. Thanks to Olof for helping identify the minimal set!		 dgisselq 2850d 00h /zipcpu
162 Noted 64-bit integers are by extension, as are vector instructions. dgisselq 2850d 00h /zipcpu
161 Initial version of the ORConf slides, showing only the initial CPU survey. dgisselq 2850d 01h /zipcpu
160 Logic updates, and bug fix corrections to bring this in line with the current
XuLA2-LX25 SoC version. (i.e., the XuLA version was debugged and improved,
this update pushes those improvements to the mainline.)		 dgisselq 2865d 12h /zipcpu
159 Now supports building a simulator that can load ELF files, such as GCC and/or
binutils will produce.		 dgisselq 2865d 12h /zipcpu
158 Now automatically builds the toolchain by default. dgisselq 2865d 12h /zipcpu
157 Added the divide unit to the list of ZipCPU dependencies. dgisselq 2865d 12h /zipcpu
156 Fixed a compiler warning for an unused result. dgisselq 2865d 12h /zipcpu
155 Improved debug trace quality, for finding bugs after the fact. dgisselq 2865d 12h /zipcpu
154 Added timing checks on the busy and valid signals: either one of the two is
valid, or the whole is idle.		 dgisselq 2865d 12h /zipcpu
153 Adds internal link functionality to the specification document format. dgisselq 2865d 12h /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 2898d 10h /zipcpu
151 Minor formatting change. dgisselq 2898d 10h /zipcpu
150 Minor changes. dgisselq 2898d 10h /zipcpu
149 Updated the Makefile documentation and the all target. dgisselq 2898d 10h /zipcpu
148 Minor changes to get LONG_MPY working, and adjust the documentation. dgisselq 2898d 11h /zipcpu
147 Cleans up div_tb a bit, causing it to write SUCCESS out if successful and
abort if not.		 dgisselq 2898d 11h /zipcpu
