Just to confirm with you, it does make sense to conditionally parse the
token for operator<=> in libcpp (i.e. only when the cxx standard being used
is >=2a)? I'm just wondering if this does not accidentally affect other
front-ends using libcpp?
Other front ends won't setthe language to C++2a.
I think the relevant check is:
if (CPP_OPTION (pfile, lang) == CLK_CXX2A
|| CPP_OPTION (pfile, lang) == CLK_GNUCXX2A)
This can only be true for a C++ source file when the standard is C++2a.
