Brad King d912220eaa cmTarget: Lookup targets in LinkInterface and LinkImplementation
Instead of storing just the string names in these structures, lookup any
target associated with each item and store its cmTarget pointer.  Use
the cmLinkItem class to hold the name and pointer together.  Update
client sites to use the pre-stored lookup result instead of looking up
the target name again.

Create a cmTarget::LookupLinkItems helper method to handle the lookup.
Since lookups are now moving from cmComputeLinkDepends::AddLinkEntries
to cmTarget::LookupLinkItems, move use of CheckCMP0004 to the latter.
This drops use of CheckCMP0004 from entries added for _LIB_DEPENDS
variables by cmComputeLinkDepends::AddVarLinkEntries, but I do not
think that use was intentional originally anyway.

Brad King a272344228 Fix scope of transitive target name lookups
In cmTarget, cmGeneratorTarget, and cmGeneratorExpressionEvaluator, fix
target name lookups to occur in the cmMakefile context of the target
that referenced the name, not the current 'head' target.  The context
matters for imported targets because they are directory-scoped instead
of globally unique.  We already do this in cmComputeLinkDepends and
cmComputeTargetDepends.

Extend the InterfaceLibrary test with an example covering this behavior.

Brad King 0dc9e88d76 cmTarget: Remove 'head' argument from GetLinkImplementation
Many of the 'head' arguments added by commit v2.8.11~289^2~1 (Make
linking APIs aware of 'head' target, 2013-01-04) turned out not to be
needed.  The "link implementation" of a target never needs to be
computed with anything but itself as the 'head' target (except for
CMP0022 OLD behavior because then it is the link interface).

Remove the unused 'head' target paths.  Add "internal" versions of
cmTarget::GetDirectLinkLibraries and GetLinkImplementationLibraries
to support the CMP0022 OLD behavior without otherwise exposing the
'head' target option of these methods.

Stephen Kelly 4f1c71fdd2 cmTarget: Add all sources traced from custom commands at once.
The AddSource method accepts one file and tries to avoiding adding
it to the sources-list of the target if it already exists.  This
involves creating many cmSourceFileLocation objects for matching
on existing files, which is an expensive operation.

Avoid the searching algorithm by appending the new sources as one
group.  Generate-time processing of source files will ensure
uniqueness.

Add a new AddTracedSources for this purpose.  The existing
AddSources method must process the input for policy CMP0049, but
as these source filenames come from cmSourceFile::GetFullPath(),
we can forego that extra processing.

Stephen Kelly 92e2fbe103 cmGeneratorTarget: Trace cmSourceFile objects instead of strings.
This reverses the decision in commit d38423ec (cmTarget: Add a
method to obtain list of filenames for sources., 2014-03-17).  The
cmSourceFile based API is preferred because that avoids creation of
many cmSourceFileLocation objects for matching strings, and the
result is cached by cmTarget.
2014-04-06 10:02:34 +02:00
Stephen Kelly c5b26f3bec cmTarget: Cache the cmSourceFiles in GetSourceFiles.
Avoid calling GetSourceFiles with the same result container multiple
times when tracing target dependencies.  The result from the previous
configuration is cached and used later otherwise.
2014-04-06 10:02:34 +02:00
Stephen Kelly e6971df6ab cmTarget: Make the source files depend on the config.
Disallow the use of config-specific source files with
the Visual Studio and Xcode generators. They don't have
any way to represent the condition currently.

Use the same common-config API in cmQtAutoGenerators. While
it accepts config-specific files, it doesn't have to support
multiple configurations yet.

Loop over the configs in cmTargetTraceDependencies
and cmGlobalGenerator::WriteSummary and consume all source
files.

Loop over the configs in cmComputeTargetDepends and compute the
object library dependencies for each config.
2014-04-02 23:14:02 +02:00
Stephen Kelly df753df94b cmGeneratorTarget: Don't add computed sources to the target.
When config-specifig generator expressions are supported, a target
may have SOURCES:

 src1.cpp $<$<CONFIG:Debug>:src2.cpp> $<$<CONFIG:Release>:src3.cpp>

and computation in cmTargetTraceDependencies would add each of the
src2.cpp and src3.cpp sources back to the target without a
config-guard.  That would make the sources be used later when
generating the buildsystem, regardless of the configuration.

Avoid calling AddSource on the target with the result of the
GetSourceFiles call.
2014-04-02 23:14:02 +02:00
Stephen Kelly aa0a3562dd cmGeneratorTarget: Compute target objects on demand
Add a ComputeObjectMapping method to compute the object
names.  It takes mapping to populate as an out-parameter so
that it can be extended in the future with parameters
relevant to generator expression evaluation.

Remove the supporting cmGeneratorTarget::AddObject method. It is
no longer needed as the container member is populated directly.

The ComputeObjectMapping method is called whenever objects are
requested from the cmGeneratorTarget.  Because the Xcode generator
makes no such request, explicitly invoke the method from that
generator so that the logic of checking for bad sources in object
libraries is executed.

In a follow-up, the UseObjectLibraries usage may be replaced by a
true generator expression evaluator for TARGET_OBJECTS. That
will require generators to use cmGeneratorTarget::GetExternalObjects
which is not currently the case for Xcode and VS generators.

Brad King f154475b65 cmTarget: Refactor GetLocation API
When given a non-NULL configuration the GetLocation returned the
location for the given configuration.  When given a NULL configuration
the GetLocation method returned a location with the build-system
placeholder for the configuration name.  Split the latter use case out
into a separate GetLocationForBuild method and update call sites
accordingly.

Ben Boeckel 270eb96df0 strings: Remove cmStdString references
Casts from std::string -> cmStdString were high on the list of things
taking up time. Avoid such implicit casts across function calls by just
using std::string everywhere.

The comment that the symbol name is too long is no longer relevant since
modern debuggers alias the templates anyways and the size is a
non-issue since the underlying methods are generated since it's
inherited.

Rolf Eike Beer c768e398f9 cmMakefile: make some methods take const std::string& instead of const char*
Most callers already have a std::string, on which they called c_str() to pass it

std::string directly to these methods now, avoiding all these conversions.
Those methods that only pass in a const char* will get the conversion to
std::string now only once.

Stephen Kelly faedd2bea9 cmTarget: Fix system include annotation propagation.
Direct users of IMPORTED targets treat INTERFACE_INCLUDE_DIRECTORIES
as SYSTEM, after commit a63fcbcb (Always consider includes from IMPORTED
targets to be SYSTEM., 2013-08-29).  It was intended that transitive
use of an IMPORTED target would have the same behavior, but that
did not work.  The implementation processed only direct dependencies
in cmTarget::FinalizeSystemIncludeDirectories.

Implement transitive evaluation of dependencies by traversing the
link interface of each target in the link implementation.

Define a custom ordering functor to deterministically and strictly

directory differentiates them.

Brad King 470f39cf4e VS: Restore header files marked as OS X Framework content (#13196)
Header files listed in a target's PUBLIC_HEADER or similar properties

 commit 11d9b211 (Add cmGeneratorTarget to represent a target during generation, 2012-03-07)
 commit 45c2f932 (Simplify cmMakefileTargetGenerator using cmGeneratorTarget, 2012-03-07)
 commit 328c0f65 (Simplify cmVisualStudio10TargetGenerator source classification, 2012-03-19)

and related commits accidentally removed such files from treatment as
normal header files by the VS generator (generators other than Makefiles
and Xcode).  Move handling of such files out of cmGeneratorTarget and
back to cmMakefileTargetGenerator.  The central cmGeneratorTarget
classification will always treat them as header or extra sources.

Brad King 9a2c60eb83 Classify known header file extensions as headers
Commit 328c0f65 (Simplify cmVisualStudio10TargetGenerator source
classification, 2012-03-19) introduced the first use of source
classification from cmGeneratorTarget (which originated as Makefile
generator logic) in a Visual Studio generator for handling of header
files.  Fix classification of header files to match known header
extensions instead of only the HEADER_FILE_ONLY property.  Make it
consistent with the "Header Files" source group.

Brad King 1c489923d5 Always compile sources with known language
Refactoring by commit 11d9b211 (Add cmGeneratorTarget to represent a
target during generation, 2012-03-07) and commit 45c2f932 (Simplify
cmMakefileTargetGenerator using cmGeneratorTarget, 2012-03-07) preserved
behavior introduced by commit 7740ccd1 (some cleanup of the makefile
generator, 2006-02-14) that favored the IgnoreFile extension test over
the availability of a known compilation language associated with a
source file.  If a source is not marked as HEADER_FILE_ONLY and has a
known language extension or an explicit LANGUAGE property it should be
treated as that language.  The LANGUAGE source file property
documentation says so.

Brad King b87d7a60a0 Add OBJECT_LIBRARY target type
This library type can compile sources to object files but does not link
or archive them.  It will be useful to reference from executable and
normal library targets for direct inclusion of object files in them.

Diagnose and reject the following as errors:

* An OBJECT library may not be referenced in target_link_libraries.

* An OBJECT library may contain only compiling sources and supporting
  headers and custom commands.  Other source types that are not normally
  ignored are not allowed.

* An OBJECT library may not have PRE_BUILD, PRE_LINK, or POST_BUILD
  commands.

* An OBJECT library may not be installed, exported, or imported.

Some of these cases may be supported in the future but are not for now.

Teach the VS generator that OBJECT_LIBRARY targets are "linkable" just
like STATIC_LIBRARY targets for the LinkLibraryDependencies behavior.
2012-03-13 14:37:32 -04:00
Brad King 11d9b21126 Add cmGeneratorTarget to represent a target during generation
Some per-target information and logic is common to all generators.
Some of that information is currently stored in cmTarget but that
should be reserved for the configure step.  Create a class to hold
per-target information for generators.  On construction classify
