166 fixed additional issues with range checking on PCREL relocations for open8, added test cases to verify, catch tree up with binutils datestamp 20120301 khays 4482d 02h /open8_urisc/trunk/
165 fixed issues with PC relative fixups in the linker khays 4483d 09h /open8_urisc/trunk/
164 Modified the data path to allow the bus to go idle while waiting for an interrupt. This makes it easier to debug code that uses the WAI instruction, as both Wr_Enable and Rd_Enable go low. jshamlet 4553d 21h /open8_urisc/trunk/
163 sync with binutils 2.22.51.20111114 khays 4591d 08h /open8_urisc/trunk/
162 Added optional generic to specify that the BRK instruction implements a WAit_for_Interrupt (WAI) instruction instead. Logically emulates INT, but without triggering a soft interrupt. Note that the NOP instruction maps to BRK, and will not function correctly if this option is set. jshamlet 4644d 14h /open8_urisc/trunk/
161 synchronize binutils/ with gnu dev tree of 2.21.53.20110828 khays 4668d 08h /open8_urisc/trunk/
160 synchronize binutils/gas with gnu dev tree of 2.21.53.20110828 khays 4668d 08h /open8_urisc/trunk/
159 synchronize binutils/gold with gnu dev tree of 2.21.53.20110828 khays 4668d 08h /open8_urisc/trunk/
158 synchronize binutils/opcodes with gnu dev tree of 2.21.53.20110828 khays 4668d 08h /open8_urisc/trunk/
157 synchronize binutils/ld with gnu dev tree of 2.21.53.20110828 khays 4668d 08h /open8_urisc/trunk/
156 Optimized for timing,
Flattened block structure to single entity.		 jshamlet 4701d 04h /open8_urisc/trunk/
155 Fixed additional interrupt logic bug,
Optimized several blocks - including ALU, stack, program counter, and data path.		 jshamlet 4701d 23h /open8_urisc/trunk/
154 Fixed problem with missing data path override in interrupt logic. Should resolve issues with processor crashing when an interrupt occurs as a STO instruction is being executed. jshamlet 4707d 02h /open8_urisc/trunk/
153 Fixed bug in interrupt logic that caused stack pointer to increment if interrupt occurred as specific instructions were being decoded,
Fixed bug in interrupt logic where instruction caching would remain enabled during an interrupt, causing improper execution depending on what instruction was in the decode stage as the interrupt is trigered.		 jshamlet 4733d 21h /open8_urisc/trunk/
152 Correct the descriptions for GMSK and SMSK instructions in the Open8 Assembly Language Reference khays 4742d 00h /open8_urisc/trunk/
151 Fixed STO instruction and interrupt logic to avoid address bus corruption issues. jshamlet 4744d 00h /open8_urisc/trunk/
150 Updated the assembly language reference to add the CLR pseudo-mnemonic khays 4744d 08h /open8_urisc/trunk/
149 added clr "Clear Accumulator" pseudo-instruction khays 4744d 10h /open8_urisc/trunk/
148 catch up with binutils trunk through date-version 20110613 khays 4745d 04h /open8_urisc/trunk/
147 GNU binutils port for Open8 - addition of all remaining files khays 4753d 22h /open8_urisc/trunk/
