Summary | 0014009: /LTCG option does not cause LinkTimeCodeGeneration to be set in project file | ||||||||
Description | Adding the /LTCG linker option to LINK_FLAGS or STATIC_LIBRARY_FLAGS should cause LinkTimeCodeGeneration to be set in the project file. For instance: <Tool Name="VCLinkerTool" ... LinkTimeCodeGeneration="1" /> This flag has the following forms that correspond to values 1-4 for the LinkTimeCodeGeneration attribute: Option XML Attribute Value --------------------------------------- /LTCG 1 /LTCG:PGINSTRUMENT 2 /LTCG:PGOPTIMIZE 3 /LTCG:PGUPDATE 4 See: http://msdn.microsoft.com/en-us/library/xbf3tbeh.aspx [^] | ||||||||
Steps To Reproduce | Add /LTCG to the linker (or librarian) using: foreach(CONFIG _RELEASE _MINSIZEREL _RELWITHDEBINFO) set_property(TARGET foo APPEND PROPERTY LINK_FLAGS${CONFIG} "/LTCG") endforeach() foreach(CONFIG _RELEASE _MINSIZEREL _RELWITHDEBINFO) set_property(TARGET bar APPEND PROPERTY STATIC_LIBRARY_FLAGS${CONFIG} "/LTCG") endforeach() Generate a Visual Studio project file. | ||||||||
Additional Information | I'm observing this on Visual Studio 2008. This bug is similar to bug 0010263; though that bug dealt with the compiler option and this one is about the related linker option. | ||||||||

For VS >= 10 we generate the flag mappings from MSBuild rule files, but for VS <= 9 we have to hand-code the table. Try this patch which backports the VS 10 table entries (untested):diff --git a/Source/cmLocalVisualStudio7Generator.cxx b/Source/cmLocalVisualStudio7Generator.cxx index dfe8280..1872d60 100644 --- a/Source/cmLocalVisualStudio7Generator.cxx +++ b/Source/cmLocalVisualStudio7Generator.cxx @@ -548,6 +548,16 @@ cmVS7FlagTable cmLocalVisualStudio7GeneratorLinkFlagTable[] = "Image may be rebased at load-time", "2", 0}, {"SetChecksum", "RELEASE", "Enable setting checksum in header", "true", 0}, {"SupportUnloadOfDelayLoadedDLL", "DELAY:UNLOAD", "", "true", 0}, + {"LinkTimeCodeGeneration", "", + "Default", "Default", 0}, + {"LinkTimeCodeGeneration", "LTCG", + "Use Link Time Code Generation", "UseLinkTimeCodeGeneration", 0}, + {"LinkTimeCodeGeneration", "LTCG:PGInstrument", + "Profile Guided Optimization - Instrument", "PGInstrument", 0}, + {"LinkTimeCodeGeneration", "LTCG:PGOptimize", + "Profile Guided Optimization - Optimization", "PGOptimization", 0}, + {"LinkTimeCodeGeneration", "LTCG:PGUpdate", + "Profile Guided Optimization - Update", "PGUpdate", 0}, {"TargetMachine", "MACHINE:I386", "Machine x86", "1", 0}, {"TargetMachine", "MACHINE:X86", "Machine x86", "1", 0}, {"TargetMachine", "MACHINE:AM33", "Machine AM33", "2", 0}, |
