The --trace option is helpful, but sometimes, what you're looking for is
deep under many layers of function calls and figuring out what instance
of the function call you're looking at is tedious to determine (usually
involving patching and message()). Instead, add a --trace-expand option
to trace while expanding commands into what CMake actually sees.
Instead put a sentinal empty entry in the container when a property
is overwritten. Use this sentinal when reading from the containers.
Use iterator::operator+(size_type) directly instead of std::advance,
because this only really makes sense if using RandomAccessIterators.

The fix in commit v3.2.3~3^2 (Fix assertion failure on unmatched foreach
in function, 2015-05-18) broke handling of unmatched non-loop blocks
because it assumed all function blockers removed during error unwinding
were for loops, essentially switching the set of mishandled cases.
The purpose of the loop block push/pop operations is to define a scope
matching the lifetime of the loop function blockers. Since our function
blockers already have the proper lifetime, simply move the push/pop
operations to their constructor/destructor.
Extend the RunCMake.Syntax test with a case covering this.
The cmListFileArgument currently stores a FilePath for use in this
method. The filename is the same as the CMAKE_CURRENT_LIST_FILE,
except if executing a macro or function defined in another file.
Set the context filename when expanding the arguments of macros and
functions using the filename recorded when defining the prototype.
Don't pay a penalty for it in all GetProperty calls.
Additionally, the storage of properties will eventually move to
cmState, which should only contain state and not logic for policies
like this.
The chaining logic doesn't belong to the container, and the
CMakeInstance pointer doesn't need to be in cmPropertyMap.
Size goes from 56 to 48 bytes with GNU libstdc++-5.1.

Compute deterministic GUIDs that are unique to the build tree by
hashing the path to the build tree with the GUID logical name.
Avoid storing them in the cache, but honor any found there.
This will allow project GUIDs to be reproduced in a fresh build
tree so long as its path is the same as the original, which may
be useful for incremental builds.
3b880a07 cmLocalGenerator: Require a valid cmState::Snapshot in the ctor.
e12afe76 cmState: Host some state from the cmGlobalGenerator.
c7b79aa1 cmGlobalGenerator: Require a cmake instance in ctor.
01e1cd5c cmState: Move snapshot creation to the cmake instance.
Refactor the local generator creation API to accept a
cmState::Snapshot. Adjust MakeLocalGenerator to use the 'current'
snapshot in cases where there is no parent. Create the snapshot
for subdirectories in cmMakefile::AddSubdirectory.
This means that snapshots are now created at the point of extending the tree,
as appropriate, and independently of the cmLocalGenerator and cmMakefile they
represent the state for.
In cmMakefile::PushScope, a copy of the closure of keys initialized
in the parent scope is made. In PopScope, essentially the same copy
is inserted back into the parent. That means a lot of duplication
of strings and a lot of string comparisons. None of it is needed,
because the cmDefinitions keys already provide a canonical
representation of what is initialized.
The removal of the separate container also makes the variable handling
code more easy to reason about in general.
Before this patch, configuring llvm uses 200 KiB for the VarInitStack.
Overall peak memory consumption goes from 35.5 MiB to 35.1 MiB.
Presumably the intention here is to attempt to optimize memory by not
storing what is not needed. However, all keys need to be tracked
anyway to implement initialization tracking, and this special case
gets in the way of simplifying the implementation of that.
This doesn't change any observable effects because values set
to 0 are considered not to exist by the cmDefinitions API.

The backtrace will soon not be implemented in terms of a stack of
cmListFileContext objects. Keep the cmListFileContext in the API
for convenience for now.
The lexical scope counting added by commit v3.2.0-rc1~332^2~1 (Track
nested loop levels in CMake language with a stack of counters,
2014-11-18) forgot to account for scopes popped by error messages about
unclosed scopes. Teach the error handler to pop the lexical scope it
reports as unclosed. Re-order the lexical scope RAII object to be
inside the variable scope RAII object scope so that the lexical scope
is fully closed before we check assertions about variable scopes.
Extend the RunCMake.Syntax test with a case covering this.
