Minor change capturing unpredictable case for LDM -- from latest ARM reference errata 7. Changed the return type for functions provided by arm_parserLib and arm_encoderLib. They now include a symbol table, which identifies the address of labels. Clean up following changes to EmitML. Also, some other tweaks wrt evaluation.

Update that adds support for ThumbEE. /* From the ARM reference... ThumbEE Is a variant of the Thumb instruction set that is designed as a target for dynamically generated code. It is: * a required extension to the ARMv7-A profile * an optional extension to the ARMv7-R profile. */

Added support for hardware interrupts: reset, fiq and irq. This adds an extra argument to the next state functions, i.e. we now have arm_next : iiid -> HWInterrupt -> unit M and ARM_NEXT : HWInterrupt -> arm_state -> arm_state option In the absence of an interrupt, the previous behaviour is obtained with ARM_NEXT NoInterrupt : arm_state -> arm_state option The single-step behaviour for interrupts can be obtained with armLib.arm_step "" "reset" (* ARM_NEXT HW_Reset *) armLib.arm_step "" "irq" (* ARM_NEXT HW_Irq *) armLib.arm_step "" "fiq" (* ARM_NEXT HW_Fiq *) There has also been some minor tidying-up to the code.

Fixes for EmitML script. Also, get RFE instructions working (albeit very slowly) with arm_step.

Numerous assorted changes, including: - renamed some constants, e.g. sN -> psrN etc. - changed handling of IT state for architecture versions < v6T2. - some fixes to the parser and to the handling of the ADR instruction. - added a couple of functions (arm_parserLib.calc_itstate and arm_random_testingLib.arm_step_updates).

Refinements to the ground-term evaluator. To simplify things, the function update (=+) sorting conversion has been removed. Instead updates are sorted just prior to printing. The elf object file loader now includes the "data" and "rodata" sections. Poly/ML users can now build a stand-alone ARM assembler by using the code at the end of arm_evalLib.sml.
