From 6f7664a9c33b110248d0fb68bcc41fdb48396c51 Mon Sep 17 00:00:00 2001 From: Andrew Burgess Date: Tue, 23 Jun 2020 20:07:09 +0100 Subject: gdb: Convert la_name and la_natural_name to methods Convert the two language_data member variables la_name and la_natural_name to virtual methods in language_defn struct called name and natural_name respectively. The virtual methods in the language_defn base class are pure virtual, as every language must implement these, and as every language has a unique name there's no sensible default here. Given that every language must implement these methods I did wonder about making this data passed into the base class constructor, but in the end I went with the virtual method approach. I'm open to changing this approach if people prefer the constructor approach. During updating the calls to language_defn::name I found in add_set_language_command a place where we took la_name and then capitalised the first letter to create a language name that could be used in the documentation string. I replaced this with a use of natural_name instead as this seemed a better choice, in most cases this will make no difference, as for most languages the natural_name is just the name with the first character in upper case, but for some languages, for example 'Open-CL' and 'Objective-C' this is not the case. In the case of asm_language the name is 'asm', while the natural_name was previously 'assembly'. I changed the natural name to 'Assembly', this makes the documentation string case above cleaner, however, this will change the MI output for -var-info-expression, where the 'lang' field will change from 'assembly' to 'Assembly'. It is possible this could be a breaking change if a front-end is relying on the existing name. gdb/ChangeLog: * ada-lang.c (ada_language_data): Remove la_name and la_natural_name initializers.
