LLVM uses .h as its extension for header files.
Files renamed using:
for f in libcxx/test/support/*.hpp; do git mv $f ${f%.hpp}.h; done
References to the files updated using:
for f in $(git diff master | grep 'rename from' | cut -f 3 -d ' '); do
a=$(basename $f);
echo $a;
rg -l $a libcxx | xargs sed -i '' "s/$a/${a%.hpp}.h/";
done
HPP include guards updated manually using:
for f in $(git diff master | grep 'rename from' | cut -f 3 -d ' '); do
echo ${f%.hpp}.h ;
done | xargs mvim

// TESTING memory_resource * get_default_resource() noexcept;
|
|
// memory_resource * set_default_resource(memory_resource*) noexcept;
|
|
//
|
|
// Concerns:
|
|
// A) 'get_default_resource()' returns a non-null memory_resource pointer.
|
|
// B) 'get_default_resource()' returns the value set by the last call to
|
|
// 'set_default_resource(...)' and 'new_delete_resource()' if no call
|
|
// to 'set_default_resource(...)' has occurred.
|
|
// C) 'set_default_resource(...)' returns the previous value of the default
|
|
// resource.
|
|
// D) 'set_default_resource(T* p)' for a non-null 'p' sets the default resource
|
|
// to be 'p'.
|
|
// E) 'set_default_resource(null)' sets the default resource to
|
|
// 'new_delete_resource()'.
|
|
// F) 'get_default_resource' and 'set_default_resource' are noexcept.
