IA64 ISA simulator, Alpha release, version 0.1 Updated to version 0.5 by Chuck Crayne <ccrayne@pacific.net> Latest version of ia64sim.zip available at www.pacific.net/~ccrayne/ia64.html ----------------------------------------------------------------- License ------- This source distribution is placed in the public domain by its author, Jason Papadopoulos. You may use it for any purpose, free of charge, without having to notify anyone. I disclaim any responsibility for any errors, inconsistencies, and inaccuracies with real-world hardware implementations of the IA64 instruction set. If you build a mission- critical system based only on this simulator and something goes wrong, it's your own damned fault. Optionally, please be nice and tell me if you find this source to be useful. Again optionally, if you add to the functionality present here please consider making those additions public too, so that others may benefit from your work. --jasonp@glue.umd.edu To compile ---------- Unix systems: unzip -a -L ia64sim.zip cd ia64sim make -f makefile.unx DOS-based gcc: pkunzip -d ia64sim.zip cd ia64sim make -f makefile.dj Windows VC++: never tried it, but change the int64 typedefs in ia64.h and compile all the .c files except make_isa.c [In version 0.2, define WIN32 to ia64.h] You'll need a replacement for strtoll() and strtoul() To Do ----- Make a working register stack Finish off the ISA (I will *not* do it all! Likewise, no one *else* should reinvent the x86 ISA for this simulator, it's just too much work) Changes in Version 0.2 ------------------- 1. Implements the "G" command, which runs the code from the current IP until any error or break is encountered. 2. Issues a stop to clear the hazards status when the IP is manually changed. 3. Adds compile, decode, and execute support for break.i, break.b, break.m, and break.f instructions. 4. Fixes bug with indirect memory references, such as ld8 r7,[r1],r5. 5. Returns error code (instead of just message) in pop_stack_frame if stack is empty. 6. Fixes a compile problem in b_unit.c:92 assigning int64 to structure. 7. Returns error message instead of aborting when can't open file specified in "C" command. 8. Supports M$ int64 types by defining WIN32 Changes in Version 0.3 ---------------------- 1. All commands shown in help screen are now implemented. 2. "C" and "L" commands now set the program startup environment as per the Intel "Software Conventions and Runtime Architecure Guide". 3. The disassembly output for the "alloc" instruction has been changed from "alloc r=ar.pfs, i, l, o, r" to "alloc r=ar.pfs, {i+l}, o, r" to reflect the actual machine encoding. Previous versions attempted to guess the split between "input" and "local" registers, often resulting in impossible values, such as "7, -2, 2, 0". Changes in Version 0.4 ---------------------- 1. First draft of a user manual (doc/ia64user.txt) 2. Systems calls to vprintf and program exit 3. Enhancements to single step and display register commands 4. Trace level command 5. Reset hazards command 6 Various bug fixes Changes in Version 0.5 ---------------------- Supports ELF files created by the Intel IA64 Assembler. Not all relocation types are yet supported.
