From 0d201fa46059ddd27980ccf8cca8488ac98b89be Mon Sep 17 00:00:00 2001 From: Andrew Burgess Date: Sun, 12 Jul 2020 15:09:52 +0100 Subject: [PATCH] gdb: Convert language_data::la_case_sensitivity to a method Convert language_data::la_case_sensitivity member variable to a virtual method language_defn::case_sensitivity. This is mostly straight forward. The only slight problem is that I ended up deleting this comment from ada-lang.c: /* Yes, Ada is case-insensitive, but that's not quite what this means. */ However, as the comment (which has existed since Ada support was first added to GDB) doesn't explain _why_ Ada sets case sensitivity to on despite being a generally case insensitive language, this doesn't really help me much. If I understood _why_ the setting doesn't quite mean what it seems to mean (at least as far as Ada is concerned) then I would extend the comment on language_defn::case_sensitivity (in language.h) to include the detail, and note how this impacts Ada. But as it stands I've just deleted the comment for now. There should be no user visible changes after this commit. gdb/ChangeLog: * ada-lang.c (ada_language_data): Remove la_case_sensitivity initializer. * c-lang.c (c_language_data): Likewise.
