# For library symbols that can be defined in more than one header
# file, maps from symbol-name to legitimate header files.
# This list was generated via
# grep -R '__.*_defined' /usr/include | perl -nle 'm,/usr/include/([^:]*):#\s*\S+ __(.*)_defined, and print qq@ { symbol: [ "$2", public, "<$1>", public ] },@' | sort -u
# I ignored all entries that only appeared once on the list (eg uint32_t).
# I then added in NULL, which according to [diff.null] C.2.2.3, can
# be defined in <clocale>, <cstddef>, <cstdio>, <cstdlib>,
# <cstring>, <ctime>, or <cwchar>. We also allow their C
# equivalents.
# In each case, I ordered them so <sys/types.h> was first, if it was
# an option for this type. That's the preferred #include all else
# equal. The visibility on the symbol-name is ignored; by convention
# we always set it to private.

# Kludge time: almost all STL types take an allocator, but they

# For instance, when adding two strings, we end up calling
# template<_CharT,_Traits,_Alloc> ... operator+(
# basic_string<_CharT,_Traits,_Alloc>, ...)
# These look like normal template args to us, so we see they're
# used and declare an iwyu dependency, even though we don't need
# to #include the traits or alloc type ourselves. The surest way
# to deal with this is to just say that everyone provides
# std::allocator. We can add more here at need.
