Subject: [PATCH 004/116] Call get_language_options from get_goto_model

This allows language frontends to consume command-line options,
which were previously left uninitialised when using goto-analyzer

Subject: [PATCH 005/116] Adding tests for function pointer removal

These tests demonstrate the different ways in which we could easily do
better in function pointer resolution. At the moment, each example
thinks the function pointer could be any of the 9 functions but in all
cases can do much better (either know exactly the function or subset of
functions)

Added const to arrays that aren't modified which will then be used to
determine arrays whose contents can be known.

Added test for arrays that are not constant and are in fact
modified.

Adding test for when FP array declared as a pointer

The function pointer optimsation can be further improved by dealing
with things like structs and pointers to function pointers. More
detail is outlined in https://github.com/diffblue/cbmc/issues/476

Added test for nullptr terminated arrays

Adding const struct regression tests

FPs may not always be assigned into a const FP and instead may be called
in place (e.g. directly from the array). This modifies the exprt
structure that must be unpacked. These tests demonstrate the different
ways that can be done.

Adding and correcting tests for pointers to FPs

From 995f5045c28ccc30aeebb2d7205ef415b00ca843 Mon Sep 17 00:00:00 2001
From: thk123 <thomas@diffblue.com>
Date: Mon, 30 Jan 2017 14:16:01 +0000
Subject: [PATCH 006/116] Made remove_function_pointers inherit from messaget

This will allow for the logging to be done through the debug() channel
and hence turned on and off.

Subject: [PATCH 013/116] Fixing todo to use separate array

When trying to resolve the functions of a component, we don't use the
array directly in case the step fails and therefore we shouldn't add
them to our list.

Subject: [PATCH 014/116] Corrected const-ness for components

We require either the struct to be const, or the type of the component
to be const (not the value the component is assigned, which will rarely
be const).

Subject: [PATCH 019/116] Added tests to cover a couple of missed lines

42 also demonstrates a bug that this commit fixes with index accessed
function calls that fail to resolve the array. Specifically, if
squashing the struct failed, we still returned true. That happens in
this instance as the pointer to the struct is not constant.

Subject: [PATCH 020/116] Fixed issue with structs with other components

If the component was not the top level thing (e.g., as in 44, it was a
pointer to a FP) we weren't correctly resolving structs that had other
components (the get_component_number does not in general work). Made the
two different handlings of the ID_member behave consistently and
correctly.

Also would have failed on 46 where the component was const but the
struct was not as was checking the type of the component value rather
than the component type itself.

Subject: [PATCH 024/116] Fixed major bug with non const structs

I had misunderstood and thought that a non const struct with a const
member couldn't have the value changed, so this was sufficent. However,
as I demonstrate in all the failing tests (which I've fixed) you can
also overwrite the entire struct. Instead, we now require when squashing
member access, that the struct itself be const (we don't care whether
the member is or not, since if it is and the struct isn't, it can be
overwritten, and if it isn't and the struct is, its value cannot be
changed).

Also, all the tests that rely on this have been modified to require no
pointer optimization.

Since we now require all symbols to be const (the only exception before
was structs with const components, but that is not sufficent), the
preliminary sweep for symbols is sufficent to catch all valid ones.

Subject: [PATCH 027/116] Adding consistency checks for the output

If the output of removing the FPs is true, then we expect at least one
function to replace the call with. If it is false, then we don't expect
any functions. If these fail, it probably indicates a bug in the
remove_const_function_pointerst class.

Subject: [PATCH 030/116] Tidied up tests

Consistent indentation
Consistent functions for the function pointers.
Made braces appear on the next line.
Made all structs include at least two components.
Corrected the name of two of the tests.
Remove unused imports.
Made all the mains return int so they compile with clang with no
warnings.
Enabling debug output for all tests so can see the output
Removing out of date comments from the tests
Missing empty lines

Subject: [PATCH 032/116] Refactored resolve_index_of_function_call

resolve_index_of and resolve_index_of_function_call both involved
squashing down an array, the function call just made a different
recurssive call at the end. Therefore it is equivalent to squash the
entry and call the resolve function call on the final result.

Subject: [PATCH 034/116] Made the behaviour of try_resolve_function_call

use and having lots of exit points to the function, all steps use same
interface and work in the same way with arrays.

Subject: [PATCH 038/116] Adding the pointer check flag

To handle the cases where the function pointer is null, we enable the
pointer--check flag. This asserts that one of the branches is taken
(e.g. a valid function pointer). This wasn't supported by goto-analyze
so added the option to it.

Subject: [PATCH 041/116] Swap to using an unorded set

Modified the tests to not assume the order of the functions.

For precise tests no further changes are required since if
the removal failed, there will be a label before the call to be jumped to.

For the no-match tests, no further changes are required since the
goto statements are being verified to be all the there.

For the approx tests, we need to verify that
the other case statements aren't present in the GOTO program to be sure
that the FP removal has been successful. As such, the other case
statements are added to the exclude section.

Subject: [PATCH 042/116] Added flag for goto-instrument to just remove const
 function pointers

Added a flag --remove-const-function-pointers for goto-instrument that
can be used
instead of --remove-function-pointers to only remove function pointers
where we can resolve to something more precise that all functions with a
matching signature.

Subject: [PATCH 043/116] Check the GOTO program for loss of const

Before removing const function pointers using remove_const_function_pointerst
we check each instruction in the goto program for assigns where the RHS
is more const than the LHS. This includes both implicit and explicit
casting away of const.

If this has happened to something relating to a function pointer, then
our optimization is not sound, so if we find any we just abandon this
optimization. This is acceptable since it is undefined behavior anyway
to be modifying a const variable.

From 29e7e0de382778dc341bf4858e2cd1f76964d0cd Mon Sep 17 00:00:00 2001
From: thk123 <thomas@diffblue.com>
Date: Mon, 20 Mar 2017 12:57:23 +0000
Subject: [PATCH 047/116] Split out the const check into own analysis

Created a standalone class to check whether a prgram contains a cast
that loses the const-ness of something that would allow modifying a
constant value (i.e. undefinied behaviour).

Subject: [PATCH 050/116] Use pointers in is_type_at_least_as_const_as

To avoid unnecessary temporary objects, use a pointer when checking for
const preservation.

Note we now need to compare the ID against NIL rather than the empty
string since the non-const version of subtype returns a new irept with
no id, but the const version returns the nil data structure.

Subject: [PATCH 055/116] Improved chain.sh to remove old .gb files first

previous runs. This ensures that if the goto-cc step fails, misleading
results are not generated.

Subject: [PATCH 060/116] Added regressions for typedefs on the source file

Since there seemed to be some sublte differences in the data that was
maintained whether you ran goto-cc first (independently) or directly fed
the .c file into CBMC. These tests replicate the behaviour of tests
found in regressions/goto-instrument-typedef/

Subject: [PATCH 063/116] Fixed the failing ANSI-C test caused by typedef types
 not being equal

Previously, basic types were being compared by directly calling
operator== on the two types. However, we now add a flag to all types
defined with a typedef saying what the typedef'd name was. This was
causing the two types to not be equal.

Now, instead of directly comparing them, we remove the ID_C_typedef flag
from them if present and then compare the resulting types.

Also added a few more checks to the test to cover some other typedef
cases.

Subject: [PATCH 073/116] Tests for variable sensitivity in goto-analyzer

This is the test suite for the variable sensitivity feature in goto-analyzer,
which will be in a separate PR. It will allow us to control which abstract
domain to use for arrays, pointers and structs separately.

From dfc3b6ef726d11e6c9405663057c5b9327ccee70 Mon Sep 17 00:00:00 2001

Subject: [PATCH 074/116] Support --property with --reachability-slice

Make the support for property-guided slicing the same for both
--full-slice and --reachability-slice. Furthermore replace sliced code
by assume(false) instead of unbounded (self-)loops.

Subject: [PATCH 084/116] Enable ccache on Travis, plus travis.yml
 restructuring

All jobs now have ccache enabled, which means that subsequent compilation should be able to reuse the compiled files, and thus the job running time should be faster.

As part of the above, travis.yml needed to be restructured, in particular:
* instead of running the compilation and tests as one command, they are split
* cegis etc. compilation takes place before the tests are run.

From 82cbd73d43dbedb37c50b833bd8536299c3c0200 Mon Sep 17 00:00:00 2001
From: Vojtech Forejt <forejtv@gmail.com>
Date: Thu, 6 Apr 2017 17:19:18 +0100
Subject: [PATCH 104/116] Allow long long int instead of just long int in
 regexp of some tests.

This prevents spurious test failures on Windows. Fixes #769.

Subject: [PATCH 108/116] Make it clear test isn't really working

CBMC can't cope with arrays as parameters to C functions yet. It
assumes they are null pointers. I'm not sure why this test was
passing, but refactoring it to not use arrays makes it clear it
shouldn't be. (Also remove some unneeded whitespace.)

Subject: [PATCH 112/116] Add appveyor.yml

Currently we use config set in an AppVeyor UI, which is inconvenient:
It is tedious to edit, and config cannot be modified per branch. With
this commit, we are taking a similar approach as the one Travis has.

The config file largely mirrors what was being used in the UI config
up until now. There is a couple of tests we delete before `make test`
is run, see #623 for more info.
