Brad King 9da84ab64a Ninja: Fix regression in .rsp file support
In commit a390de65 (Ninja: Generate separate compile and link rules for
each target, 2015-05-18) we removed the _RSP_FILE suffix from rule names
meant for targets that need to build with a .rsp file because we now use
per-target rules anyway.  Remove this suffix from references to the rule
too.

Brad King 700f1c3b2b Honor visibility properties for all target types (#15556)
The <LANG>_VISIBILITY_PRESET and VISIBILITY_INLINES_HIDDEN were first
merged in commit v2.8.12~322 (Merge topic 'VISIBILITY_PRESET-property',
2013-06-05) but worked only for shared libraries and executables with
exports.  Prior to commit v3.0.0-rc1~581^2 (GenerateExportHeader:
Deprecate add_compiler_export_flags function., 2013-09-02) the
add_compiler_export_flags function was used to add visibility flags to
all targets.

The visibility flags are useful for sources in all target types because
they may be later linked into shared libraries or executables with
exports.  Introduce policy CMP0063 to enable them for all target types
while preserving compatibility with existing projects that do not expect
this.

Stephen Kelly 01e1cd5c1f cmState: Move snapshot creation to the cmake instance.
Don't create a snapshot in Initialize(), but leave the creation
responsibility to the cmake instance instead.  Previously, the
cmState would Initialize() in its constructor, and the cmake instance
would re-Initialize() during Configure().  The end result was the
same and there would be one snapshot present.  However, cmLocalGenerator
also created a snapshot on construction, and that one was used, leaving
the first snapshot unused, and potential for off-by-one errors.

Fix that by making the cmLocalGenerator use the existing snapshot
if it is top-level.  Add a CurrentSnapshot to the cmake instance and
populated it while configuring a directory.  This will eventually
replace the 'current local generator' concept.  Fix the GetParent
implementation to be able to return the first snapshot.

Brad King 2f4bb4e9b0 VS: Do not accumulate configurations globally (#15577)
Drop the VS >= 7 generator's global Configurations member and instead
lookup configurations using cmMakefile::GetConfigurations where needed.
This avoids accumulating all CMAKE_CONFIGURATION_TYPES values ever
encountered by a project() or enable_language() command and allows
the final value to be used in each directory.  We don't officially
support per-directory CMAKE_CONFIGURATION_TYPES values but we certainly
should not generate configurations not in the final value in the top
level directory.

Brad King deec97d8ec Revert "Qbs: Add new 'extra' generator for qbs project files"
This reverts commit f85db2f323.

Discussion by the QtCreator community at

  https://bugreports.qt.io/browse/QTCREATORBUG-13695

raises concerns about this particular approach to working with CMake
projects using QtCreator.  Also, the functionality and design of the QBS
extra generator was never discussed on the CMake mailing list or with
QtCreator developers.  There may be better ways to make the two tools
work together.

In order to avoid committing to long-term support of this generator
prior to such discussion taking place, revert it from CMake for now.
We may restore this or use an alternative design based on results of
such discussion.

The QMacInstallDialog infrastructure no longer works on modern OS X
versions.  Drop it and replace the dialog with a simple info box that
explains to the user how to run 'cmake-gui --install' to add symlinks.
Also suggest simply modifying the PATH.

This approach is similar to the Xcode 'xcode-select --install' method
of installing Xcode Command Line Tools.

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 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 d7923b82ad Use std::unordered_map instead of hash_map where available. 2015-05-19 00:07:02 +02:00
Stephen Kelly 61d52e6e77 cmListFileBacktrace: Hide the context-stack implementation detail.
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.

Stephen Kelly a271f7f177 cmTarget: Simplify CMP0023 message loop.
This method is only called if there is a mismatch and something to
print.  Remove intermediate container.

Stephen Kelly f4300cd4dd cmTarget: Simplify output computation.
We always have line information for contexts resulting from
command execution.

Stephen Kelly 65a4284963 cmTarget: Store context in stack only if different.
The PushTLLCommandTrace method is called once per link item for a single
target_link_libraries command.  Avoid storing copies of identical
execution contexts and rely on the uniqueness while printing output.

Stephen Kelly 52a8d19c9b cmTarget: Store only cmListFileContext for CMP0023 handling.
Only the top level execution context is shown, as appropriate, so
store only that.

Stephen Kelly 59ba1215b9 cmTarget: Remove needless iteration.
This is not a loop.

Stephen Kelly 18f810a865 cmListFileContext: Sort by line before file.
This should be much faster.  In the context where it is used the
line comparison should be sufficient, removing the need to compare
files at all.

Stephen Kelly e96b5d14f9 cmListFileContext: Implement LessThanComparable.
Move wrapping existing code from cmMakefile, and simplify the
implementation there.
