* Enable simple ARM register concretization for Unicorn
* Add canonical_registers property to abstractcpu
* cpu to self
* Check for regs_access better
* Emulate a single instruction
* Bypass capstone 3.0.4 arm bug
* Dealing with capstone
* Temporary disable ASR and remobe BitVec.Bool from test
* WIP WIP debug prints WIP WIP
* Unicorn fallback working (using unicorn master)
* HAck to support unicorn 1.0.0
* WIP
* Unicorn hack to handle PC updates
* [WIP] do not do anything with this commit; for debugging only
* Adding before clean up
* emulation more or less works; need to work out more unicorn bugs
* clean up emulate() caller code
* move hooks to methods; cleanup
* Concretize memory when emulating
* Re-add Bool()
* Update tests to start at offset 4
When an instruction branches to the previous instruction,
Unicorn attempts to dereference that memory. We'd like to use
unit tests to also make sure Unicorn emulation is in line with
our own semantics. If we start all tests at offset 4, we can
jump to a previous instruction and not fault when Unicorn
dereferences it.
* Fix concretization
* Clean up test imports; upper-case Cpu
* Unicorn tests
* Add tests for all the ARM semantics, but make sure they're equivalent
on unicorn.
* Add a few tests to make sure unicorn correctly concretizes the memory
it references
* Fix broken import
* Add symbolic register tests
* Re-introduce the unicorn hack
* Add the 'ONE' concretization policy
* Rm unused function
* Update concretization; add comments
* Add ONE policy test
* Create a base class for all concretization exceptions
* Remove Armv7Cpu._concretize_registers
* Check for enabled logging in a more idiomatic way
* [wip] intermediate testing commit
* Reimplement hooks and execution with unicorn
* Add a DMB (mem barrier) instruction; nop
* simplify instruction resolution
* improve unicorn error handling
* explicitly delete emu
* Handle ARM helpers inline
* map fetched memory
* Narrow exception handling
* Update DMB docs; make __kuser_dmb match real implementation
* Fix typo; add comment; remove extraneous parameter
* typos++
