For C gcc -E helps a lot for macros. Does C++ have a tool that expands all templates?

- kazinator 8y agogcc has options for intercepting various intermediate representations of a translation unit; look into that. I just found this in the man page (for a fairly dated version of gcc): -fdump-translation-unit (C++ only) -fdump-translation-unit-options (C++ only) Dump a representation of the tree structure for the entire translation unit to a file. The file name is made by appending .tu to the source file name, and the file is created in the same directory as the output file. If the -options form is used, options controls the details of the dump as described for the -fdump-tree options. If this were Lisp, we wouldn't be scared of what "representation of the tree structure" will look like. It doesn't say anything about whether templates are expanded/instantiated.
