This adds two new symbol domain constants, TYPE_DOMAIN and FUNCTION_DOMAIN. Historically, gdb was a C debugger, and the symbol tables continue to reflect this. In particular, symbol domains match the C language, with VAR_DOMAIN including variables, functions, and types. However, other languages have other approaches to namespacing. And, in any case, it is often useful for other parts of gdb to be able to distinguish between some domains at lookup time, without resorting to examining a symbol's location -- in some situations, this sort of filtering happens too late. Nothing uses these new domains yet, but the idea behind the patch is to separate symbols into more domains and then let the language-specific parts of gdb implement their semantics in terms of these categories. --- gdb/sym-domains.def | 9 +++++++++ 1 file changed, 9 insertions(+)
