The changes include:
Clean up elf loading to fix a bug in rel addend parsing.
Introduce block preconditions for populating reopt-vcg fields.
Change load options to match reopt's interface.
I believe this is due to an ambiguity of whether the
post-documentation reference is to the previous constructor or just
the last argument of the previous constructor. By moving the haddocks
to be a pre-doc this seems to work better.
It also cannot handle the UNPACK pragma, which could probably be
removed since -funbox-small-strict-fields is on by default, but
haddock would still fail for the strictness annotation.
By moving the haddocks to the constructor instead of the individual
fields the strictness restriction can be avoided.
The goal is to support a jumptable testcase that is not supported by
the current jump bounds check. The jump bounds check needs to be
augmented so that it understands equality relationships between stack
values and registers, and bounds on both.
This patch tracks when a register points to a concrete stack offset.
As part of this, we droped the AbsDomain instance for AbsBlockState.
Clients should now likely use `fnStartAbsBlockState` in lieu of `top`.
The other client visible change is that the ClassifyFailure
constructor now has an extra argument with details about why
classification failure occured.
This introduces a new datatype CValue for representing constants
in Macaw programs, modifies the existing Value datatype to use then,
and introduces patterns for compatibility with existing datatypes.
The patch also updates the function argument analysis to use more
explicit argument passing rather than monadic updates. The intent is
to help clarify when data is initialized rather than updated.
Finally this updates a README and does some minor updates.
The parseFetchAndExecute in Discovery attempts to identify ParsedITE
terminal statements by examining the value of the ip_reg via
valueAsApp and pattern matching on a Mux statement. This patch adds
specific handling in the Macaw CFG Rewriter to attempt to float Mux
statements upwards (aka "Mux Head Normal Form") so that they will be
the top-most ip_reg value and therefore be recognized as a ParsedITE
terminator.
For macaw-ppc testing of the 988KB gzip binary, this increased the
number of blocks found from 1339 to 37950 (and increased the test
runtime from 1.36s to 88.14s).
