PR12086, PR15117 Introduce CXXStdInitializerListExpr node, representing the implicit construction of a std::initializer_list<T> object from its underlying array. The AST representation of such an expression goes from an InitListExpr with a flag set, to a CXXStdInitializerListExpr containing a MaterializeTemporaryExpr containing an InitListExpr (possibly wrapped in a CXXBindTemporaryExpr). This more detailed representation has several advantages, the most important of which is that the new MaterializeTemporaryExpr allows us to directly model lifetime extension of the underlying temporary array. Using that, this patch *drastically* simplifies the IR generation of this construct, provides IR generation support for nested global initializer_list objects, fixes several bugs where the destructors for the underlying array would accidentally not get invoked, and provides constant expression evaluation support for std::initializer_list objects. llvm-svn: 183872

[test] Add {{.*}} to make ELF tests immune to dso_local/dso_preemptable/(none) differences For a default visibility external linkage definition, dso_local is set for ELF -fno-pic/-fpie and COFF and Mach-O. Since default clang -cc1 for ELF is similar to -fpic ("PIC Level" is not set), this nuance causes unneeded binary format differences. To make emitted IR similar, ELF -cc1 -fpic will default to -fno-semantic-interposition, which sets dso_local for default visibility external linkage definitions. To make this flip smooth and enable future (dso_local as definition default), this patch replaces (function) `define ` with `define{{.*}} `, (variable/constant/alias) `= ` with `={{.*}} `, or inserts appropriate `{{.*}} `.

PR12086, PR15117 Introduce CXXStdInitializerListExpr node, representing the implicit construction of a std::initializer_list<T> object from its underlying array. The AST representation of such an expression goes from an InitListExpr with a flag set, to a CXXStdInitializerListExpr containing a MaterializeTemporaryExpr containing an InitListExpr (possibly wrapped in a CXXBindTemporaryExpr). This more detailed representation has several advantages, the most important of which is that the new MaterializeTemporaryExpr allows us to directly model lifetime extension of the underlying temporary array. Using that, this patch *drastically* simplifies the IR generation of this construct, provides IR generation support for nested global initializer_list objects, fixes several bugs where the destructors for the underlying array would accidentally not get invoked, and provides constant expression evaluation support for std::initializer_list objects. llvm-svn: 183872

[test] Add {{.*}} to make ELF tests immune to dso_local/dso_preemptable/(none) differences For a default visibility external linkage definition, dso_local is set for ELF -fno-pic/-fpie and COFF and Mach-O. Since default clang -cc1 for ELF is similar to -fpic ("PIC Level" is not set), this nuance causes unneeded binary format differences. To make emitted IR similar, ELF -cc1 -fpic will default to -fno-semantic-interposition, which sets dso_local for default visibility external linkage definitions. To make this flip smooth and enable future (dso_local as definition default), this patch replaces (function) `define ` with `define{{.*}} `, (variable/constant/alias) `= ` with `={{.*}} `, or inserts appropriate `{{.*}} `.

CodeGen: static constexpr data members should have a linkonce_odr init Classes can be defined in multiple translation units. This means that the static constexpr data members should have identical initializers in all translation units. Implement this by giving the reference temporary linkonce_odr linkage. llvm-svn: 229900
