fixit-hints draft implementation
Quoting from http://clang.llvm.org/diagnostics.html
"Fix-it" hints provide advice for fixing small, localized problems in source
code. When Clang produces a diagnostic about a particular problem that it can
work around (e.g., non-standard or redundant syntax, missing keywords, common
mistakes, etc.), it may also provide specific guidance in the form of a code
transformation to correct the problem.
$ clang t.cpp
t.cpp:9:3: error: template specialization requires 'template<>'
struct iterator_traits<file_iterator> {
^
template<>
The attached patch implements the same behavior for GCC when given
-fdiagnostic-show-caret. When the caret is disabled, it gives:
t.cpp:9:3: error: template specialization requires 'template<>'
t.cpp:9:3: fixit: template<>
so an IDE might parse the "fixit:" diagnostic and use the message to edit the
text directly.
This is work in progress I have not even tried to build gcc using this patch.
