Before this commit, if there was a failure during the verification of a
type (which is recursive), we'd get an assertion in ~VerifyHelper due to
a "pending" type still being verified.
Move much of the logic of `rp_manager_produce_targets` to a method
inside `PipelineManager`, add additional checks for the existence of the
targets that are requested to be produced.
HexDumpPipe dumps content of binary file in the similar way as hexdump
tool with addition of PTML markup for instructions addresses.
Continuous parts of binary code are wrapped with <span
data-location-definition=""></span> where data-location-definition
attribute contains Entry/BasicBlock/Instruction addresses in generic
form. <span> tags can be nested if byte(s) belong to many instructions
in code.
At the end of the line every <span> is closed and opened on the next
line again if it still applies to the next byte.
MetaAddress are converted to IntervalMetaAddress (which implements own,
optional-less operator-) and stored in boost::icl::intruval_map. This
map is used to get addresses of instructions to which each byte belongs.
getJumpTargetBlock takes llvm::BasicBlock * as argument, but doesn't
need to modify it, so const it adds const to it and other functions that
are used by getJumpTargetBlock: findJumpTarget, isTranslated, getType,
isJumpTarget.
This commit fixes a TypeShrinking bug and extends it to better handle
more instructions. Specifically, we now handle shift left, select, phi
and bitwise operations.
This commit introduces a change in AdvancedValueInfoMFI which forces to
consider constraints valid on 32-bit values to be valid on their
untruncated 64-bit counterparts.
While being unsound, this is important to easily devirtualize indirect
branches on 64-bit architectures where often constraints are expressed
on 32-bit switch values.
This analysis will be used for the following features:
1) Edit Type in the Model
2) Edit Function Prototype in the Model
3) Add Type to the Model
It takes C code as an input, parses it and produces a Model
type that represents the C type.
