Hello Clang developers,
I am back again with another patch to make Clang Lit tests C++11 compatible.
There are 26 tests in total.
These are mainly diagnostics verifications where C++98/03 and C++11 differ.
I tried to preserve as much coverage as possible.
Unless otherwise stated, these tests have their RUN line expanded to run at:
default C++ dialect, C++98 and C++11.
Here are the description of what I did with each in the order as they appear in
the patch.
test/CXX/class.access/class.friend/p2-cxx03.cpp
Only verify the following diagnostic on C++03 and earlier.
"non-class friend type 'T' is a C++11 extension"
test/CXX/dcl.dcl/dcl.spec/dcl.fct.spec/p6.cpp
Only verify the following diagnostic on C++03 and earlier.
"explicit conversion functions are a C++11 extension"
test/CXX/dcl.dcl/dcl.spec/dcl.type/dcl.type.elab/p3.cpp
Only verify the following diagnostic on C++03 and earlier.
"befriending enumeration type 'enum E' is a C++11 extension"
test/CXX/temp/temp.fct.spec/temp.arg.explicit/p3.cpp
Verify for different diagnostic between C++03 and earlier vs C++11 and later
C++03: conversion from string literal to 'char *' is deprecated
C++11: ISO C++11 does not allow conversion from string literal to 'char *'
test/CodeGen/ubsan-type-blacklist.cpp
Relaxed FileCheck string to accommodate changes in LLVM-IR on actual argument
type for "bar".
C++03: %class.Bar* @bar
C++11: { i8** }* @bar
test/FixIt/fixit-vexing-parse.cpp
Set this test to always run at C++98.
C++11 coverage is provided by fixit-vexing-parse-cxx0x.cpp.
test/SemaCXX/addr-of-overloaded-function.cpp
Only verify the following diagnostic on C++03 and earlier.
"default template arguments for a function template are a C++11 extension"
test/SemaCXX/const-cast.cpp
Only verify the following diagnostic on C++03 and earlier.
"rvalue references are a C++11 extension"
test/SemaCXX/convert-to-bool.cpp
Only verify the following diagnostic on C++03 and earlier.
"explicit conversion functions are a C++11 extension"
test/SemaCXX/copy-initialization.cpp
Only verify the following diagnostic on C++03 and earlier.
"rvalue references are a C++11 extension"
test/SemaCXX/cxx0x-return-init-list.cpp
Force this test to always run at C++03 (-std=c++98).
This test verifies for very basic initializer return support in C++98.
It checks for the following diagnostic at C++03
"generalized initializer lists are a C++11 extension"
test/SemaCXX/decltype-crash.cpp
Force this test to always run at C++03 (-std=c++98).
This test verifies against decltype crash back in 2009.
test/SemaCXX/gnu-flags.cpp
Only verify the following diagnostic on C++03 and earlier.
"in-class initializer for static data member is not a constant expression;
folding it to a constant is a GNU extension"
test/SemaCXX/invalid-member-expr.cpp
For code: pair<int, int> z = minmax({});
Empty initializer list is valid in C++11, but since minmax is not defined
anywhere in the program, compiler issues an error.
Therefore, in C++03 and earlier, we check for diagnostic: "expected
expression"
In C++11 and later, we check for diagnostic: "use of undeclared identifier
'minmax'"
test/SemaCXX/member-expr.cpp
In C++11, "template" can be used outside of a template.
Only verify the following diagnostic on C++03 and earlier.
"'template' keyword outside of a template"
test/SemaCXX/member-pointer.cpp
Only verify the following diagnostic on C++03 and earlier.
"use of enumeration in a nested name specifier is a C++11 extension"
test/SemaCXX/new-array-size-conv.cpp
Only verify the following two diagnostic on C++03 and earlier.
"implicit conversion from array size expression of type 'ValueInt' to
integral type 'int' is a C++11 extension"
"implicit conversion from array size expression of type 'ValueEnum' to
enumeration type 'E' is a C++11 extension"
test/SemaCXX/offsetof.cpp
Force this test to be C++98 only. Test offsetof-0x.cpp exists to verify for
C++11 behavior
Diagnostic change
C++98: warning: offset of on non-POD type
C++11: warning: offset of on non-standard-layout type
test/SemaCXX/printf-block.cpp
This test verifies the diagnostic when trying to pass a non-POD struct then
access its string value.
C++11 allows passing non-POD objects via va_arg (5.2.2/7). But since the
object does not have a c_str() method. So the compiler will issue a warning on
that
Here are the different diagnostics we verify for.
C++03: cannot pass non-POD object of type 'HasNoCStr' to variadic block;
expected type from format string was 'char *'
C++11: format specifies type 'char *' but the argument has type 'HasNoCStr'
test/SemaCXX/undefined-internal.cpp
Verify for different diagnostics depending on the dialect.
C++03: "C++98 requires an accessible copy constructor"
C++03: "copying parameter of type 'PR9323::(anonymous namespace)::Uncopyable'
when binding a reference to a temporary would invoke an inaccessible
constructor in C++98"
test/SemaObjCXX/crash.mm
Only verify the following diagnostic on C++03 and earlier.
"variadic templates are a C++11 extension"
test/SemaObjCXX/vararg-non-pod.mm
Only verify the following diagnostic on C++03 and earlier.
"cannot pass object of non-POD type 'C' through variadic method; call will
abort at runtime"
test/SemaTemplate/default-arguments.cpp
Only verify the following diagnostic on C++03 and earlier.
"default template arguments for a function template are a C++11 extension"
test/SemaTemplate/temp_class_spec_neg.cpp
Only verify the following diagnostic on C++03 and earlier.
"first declaration of class template partial specialization of 'A' outside
namespace 'M' is a C++11 extension"
test/SemaTemplate/typename-specifier-4.cpp
Keywords "template"and "typename" can be used outside a template in C++11.
Only verify the following two diagnostics on C++03 and earlier.
'template' keyword outside of a template
'typename' occurs outside of a template
test/SemaTemplate/typename-specifier.cpp
Only verify all occurrences the following diagnostics on C++03 and earlier.
'typename' occurs outside of a template
Cheers,
Charles
