Brad King c85367f408 VS: Compute project GUIDs deterministically
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.

Stephen Kelly 3b880a0741 cmLocalGenerator: Require a valid cmState::Snapshot in the ctor.
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.

Stephen Kelly b9f9915516 cmMakefile: Remove VarUsageStack.
Store usage information in the cmDefintions value instead.  We already
pay for the memory as padding in the Def struct, so we might as well
use it.
2015-05-19 22:36:53 +02:00
Stephen Kelly 2b09d9f346 cmMakefile: Remove VarInitStack.
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.

Stephen Kelly 528d68021c cmMakefile: Use more suitable method name to log var usage. 2015-05-19 22:36:52 +02:00
Stephen Kelly f58c3774d1 cmMakefile: Mark definitions explicitly erased, even at top level.
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.

Stephen Kelly ea7b962be2 cmMakefile: Raise variable in scope explicitly when needed.

Brad King 3a65606591 Fix assertion failure on unmatched foreach in function (#15572)
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.

The purpose of the stack is to allow access only to the top of it.  Access

The existence of the Parent pointer is a workaround for the inappropriate
use of stack in the first place.  Remove it now.

Stephen Kelly a6b1ad1309 Introduce cmState class.
At this point, it is an interface to the cache.  It will be extended
to be a universal interface for access to and manipulation of
configuration-time data (defintions, properties on targets,
directories, source files etc).

This will allow porting all command implementations away
from the cmMakefile and cmTarget classes, and result in something
more-purely related to configuration-time processing of cmake
commands.  That should serve at least the following goals:

 * Split the CMake implementation more definitively into three
   stages: Configuration, computation and generation, and be able to
   implement each optimally for memory access patterns etc.
 * Make better IDE integration possible by making more configuration
   data available.
 * Make it possiblte to use a smaller library than CMakeLib.a in
   cpack and ctest, resulting in smaller executables.
 * Make it possible to run the configure step multiple times in
   the same CMake run (#14539).

Manage its lifetime in the cmake class, and add a convenience accessor
to cmMakefile.

Gregor Jasny bae604d9a8 Track nested loop levels in CMake language with a stack of counters
It gets incremented while entering a loop block (e.g. foreach or while)
and gets decremented when leaving the block. Because scope borders for
example at function borders must be taken into account the counter is
put into a stack. With every new scope an empty counter is pushed on the
stack, when leaving the scope the original value is restored.

This will allow easy querying if the break command is properly nested

Brad King e15a7075b5 Add an option for explicit BYPRODUCTS of custom commands (#14963)
A common idiom in CMake-based build systems is to have custom commands
that generate files not listed explicitly as outputs so that these
files do not have to be newer than the inputs.  The file modification
times of such "byproducts" are updated only when their content changes.
Then other build rules can depend on the byproducts explicitly so that
their dependents rebuild when the content of the original byproducts
really does change.

This "undeclared byproduct" approach is necessary for Makefile, VS, and
Xcode build tools because if a byproduct were listed as an output of a
rule then the rule would always rerun when the input is newer than the
byproduct but the byproduct may never be updated.

Ninja solves this problem by offering a 'restat' feature to check
whether an output was really modified after running a rule and tracking
the fact that it is up to date separately from its timestamp.  However,
Ninja also stats all dependencies up front and will only restat files
that are listed as outputs of rules with the 'restat' option enabled.
Therefore an undeclared byproduct that does not exist at the start of
the build will be considered missing and the build will fail even if
other dependencies would cause the byproduct to be available before its
dependents build.

CMake works around this limitation by adding 'phony' build rules for
custom command dependencies in the build tree that do not have any
explicit specification of what produces them.  This is not optimal
because it prevents Ninja from reporting an error when an input to a
rule really is missing.  A better approach is to allow projects to
explicitly specify the byproducts of their custom commands so that no
phony rules are needed for them.  In order to work with the non-Ninja
generators, the byproducts must be known separately from the outputs.

Add a new "BYPRODUCTS" option to the add_custom_command and
add_custom_target commands to specify byproducts explicitly.  Teach the
Ninja generator to specify byproducts as outputs of the custom commands.
In the case of POST_BUILD, PRE_LINK, and PRE_BUILD events on targets
that link, the byproducts must be specified as outputs of the link rule
that runs the commands.  Activate 'restat' for such rules so that Ninja
knows it needs to check the byproducts, but not for link rules that have
no byproducts.

Peter Collingbourne fe5d6e8c0f Add USES_TERMINAL option for custom commands
Teach the add_custom_command and add_custom_target commands a new
USES_TERMINAL option.  Use it to tell the generator to give the command
direct access to the terminal if possible.

Ben Boeckel 5f414cefb6 Revert "cmDefinitions: Don't store parent lookups"
This reverts commit 5abfde6cb8.

The behaviors associated with implicit pulldown on variable lookup
seriously conflict with the optimizations made in these commits.
Basically, since values were copied upon variable lookup, not just on
PARENT_SCOPE, coupled with PARENT_SCOPE's behavior based on whether the
variable is in the current scope or not causes serious problems with not
storing a value for every variable at every scope.

The commit changed behavior of the following example, among other cases:

  function(test_set)
    set(blah "value2")
    message("before PARENT_SCOPE blah=${blah}")
    set(blah ${blah} PARENT_SCOPE)
    message("after PARENT_SCOPE blah=${blah}")
  endfunction()
  set(blah value1)
  test_set()
  message("in parent scope, blah=${blah}")

Ben Boeckel bc38565863 EVIS: Reimplement using custom parsing code
Introduce a new implementation of ExpandVariablesInString and select
between the old and new implementations based on policy CMP0053.
Instead of cmCommandArgumentParserHelper, use a custom parser with our
own stack.  This is much faster and works well for our simple grammar.

The new behavior of CMP0053 should expand @VAR@ syntax only in certain
contexts.  All existing EVIS callers use "replaceAt == true" so
hard-code our call to the old implementation.  Update the signature to
default to "replaceAt == false" and pass "replaceAt == true" explicitly
in the call sites for configure_file and string(CONFIGURE).

Testing the configure (no generate) step with ParaView shows ~20%
performance improvement.

In terms of complete configure/generate steps, further testing with
ParaView shows a 20% performance improvement over 2.8.12.2 with Unix
Makefiles and minimal with Ninja. Ninja is less because it generate step
is the expensive part (future work will address this) by a long shot and
these changes help the configure step for the most part.
