Stephen Kelly a5b59fae15 QtAutogen: Create global generator on the stack. 2015-05-20 00:30:16 +02:00
Stephen Kelly fe401ede2a QtAutogen: Use a more-obvious delete-target. 2015-05-20 00:30:15 +02:00
Stephen Kelly c95a55ad5a QtAutogen: Remove the need for a local makefile variable. 2015-05-20 00:30:13 +02:00
Stephen Kelly 460e8fb9ad QtAutogen: Inline static factory method. 2015-05-20 00:23:28 +02:00
Stephen Kelly 58f41c789f QtAutogen: Remove repeated setters.
These methods are called already just before calling the static method.

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.

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 9118b53b79 cmMakefile: Move internal method to private scope. 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.
The Get method implicitly pulls a copy of all variables into a local scope. This
is not necessary.

Stephen Kelly 390bc3244f cmMakefile: Remove redundant condition.
As this is called in the constructor, the definition will never be already
set.

Stephen Kelly f3e6a336f2 cmMakefile: Remove CurrentListFile member.
It is never read externally.  The CollapseFullPath removed in this commit
is a repeat of a similar call inside ReadListFile.

Stephen Kelly 6b9e647239 cmMakefile: Port CurrentListFile clients to GetDefinition.
There is no need to store this as a member variable.

Brad King ada5ffce7b Add options to run include-what-you-use with the compiler

CMAKE_<LANG>_INCLUDE_WHAT_YOU_USE variable) to specify an IWYU command
line to be run along with the compiler.

Bill Hoffman 67fa3da9e8 cmake: Add internal -E mode to run include-what-you-use with the compiler
Add an internal "cmake -E __run_iwyu" mode to wrap the compiler call.
Run a given include-what-you-use command line with the compiler options
and report a warning if it finds anything.  Then run the real compiler.

Brad King b3795df2f4 FortranCInterface: Do not use cmake_policy(VERSION)
Do not force a specific policy version in the module because it prevents
projects from setting newer policies to NEW.  In particular, projects
may want to set CMP0056 to NEW to affect any try_compile calls in this
module.

Use of this was added in commit v2.8.2~714 (FortranCInterface: Use CMake
2.8.0 behavior, 2009-11-17) in order to set CMP0007 to NEW.  Simply set
this policy explicitly instead.

Brad King a4596f2048 CheckTypeSize: Do not use cmake_policy(VERSION)
Do not force a specific policy version in the module because it prevents
projects from setting newer policies to NEW.  In particular, projects
may want to set CMP0056 to NEW to affect any try_compile calls in this
module.

Use of this was added in commit v2.8.2~539 (New CheckTypeSize for OS X
Universal Binaries, 2009-12-17) and updated in commit v3.1.0-rc1~511^2~1
(Do not change minimum required version in modules, 2014-05-07).  The
history does not clearly explain why a specific policy version was
introduced.  If specific policies need to be NEW then we can add
explicit settings for them.

Rolf Eike Beer 6784f0a6eb CheckTypeSize: Avoid if() auto-dereferene in quoted arguments (#15571)
Exposed by a CMP0054 warning.  Set CMP0054 to NEW since no code in this
module depends on the old behavior.
