2018-07-12update arm and mips models for new type of write_ram builtin. Also fix c and ↵Robert Norton
interpreter implementations of same.
2018-06-28RTS: Add --verbosity flag to C modelAlastair Reid
This is interpreted as a set of bits that control various bits of output. Bit 0 is print the PC on every cycle. (It would probably be useful to standardise a few of these flags across all models. Other candidates are accesses to physical memory, throwing SAIL exceptions, current privilege level, ...)
2018-06-28Add tagged memory to C rts to cheri can be compiled to CAlasdair Armstrong
2018-06-27RTS/Main: tweaking cycle counter handlingAlastair Reid
2018-06-27Add a new function cycle_limit_reached that returns bool, allowing for ↵Robert Norton
graceful exit on reaching cycle limit. This aids coverage and valgrind instrumentation.
2018-06-27RTS: Add support for __ListConfigAlastair Reid
2018-06-27RTS: Delete __SetConfig stub functionAlastair Reid
This is now directly supported from SAIL so we can call the SAIL __SetConfig function instead.
2018-06-26turn on warnings when compiling mips c then dial back ones that are ↵Robert Norton
triggered by generated code (probably false positives). Fix some warnings in rts.c
2018-06-26RTS: implement sleep primitivesAlastair Reid
Note that an alternative implementation choice is just to implement them as SAIL functions manipulating a global variable. Not sure which is better.
2018-06-21Add command line option support for Sail->C compiled modelsAlasdair Armstrong
For example, the MIPS model can boot FreeBSD as ./mips_c --binary=0x100000,/path/to/kernel --image=/path/to/simboot.sailbin Or with short options as ./mips_c -b 0x100000,/path/to/kernel -i /path/to/simboot.sailbin The current options are: -e, --elf, which loads an elf file directly -n, --entry, which sets the entry point -i, --image, which loads an image file compiled by "sail -elf" using Linksem -b, --binary, which loads a plain binary image into memory at a specific address -l, --cyclelimit, which means the (new) cycle_count() builtin exits the model after a certain number of calls Also there are the default -? --help and --usage options.
2018-06-19Add elf parsing from AlastairAlasdair Armstrong
2018-06-15Fixes for C RTS for aarch64 no it's split into multiple filesAlasdair Armstrong
Fix a bug involving indentifers on the left hand side of assignment statements not being shadowed correctly within foreach loops. Make the different between different types of integer division explicit in at least the C compilation for now. fdiv_int is division rounding towards -infinity (floor). while tdiv_int is truncating towards zero. Same for fmod_int and tmod_int.
2018-06-14Refactor C backend, and split RTS into multiple filesAlasdair
