unusedcode.README

-unusedcode.easy is generated via callcatcher[1] and filtered to remove some
-tricky edge-cases (see Makefile), e.g. anything which could plausibly be
-dlsymed or any symbol defined in an external library bundled into LibreOffice
-which doesn't happen to get used by LibreOffice.
-
-unusedcode.easy is generated on an x86_64 --enable-debug --enable-dbgutil
-configuration.
-
-Code listed as unused is code that gcc outputs but that nothing calls
-(or takes the address of).
-
-a) It's possible that some other platform or configuration uses the code,
-   so manual inspection is always required.
-b) callcatcher ignores virtuals. But implementations of "pure virtuals"
-   are not actually virtual methods. If something is declared pure virtual
-   and provides an impl and that base-class impl is not explicitly called
-   anywhere, then that impl can go away.
-c) gcc will only emit code for inlines if those inlines are used, so
-   sometimes something is listed correctly as unused but some inline
-   code takes a pointer or reference to something which cannot be
-   instantiated so removal of some method/class fails at build time because
-   gcc never emits any code for the unused inline but trips over it at
-   compile time after an attempt at removal. i.e. generally the inline method
-   can go as well because nothing calls it either, a double win.
-d) if a constructor is listed as unused, and it's the *only* ctor in the class,
-   then no object of that class can be constructed, so the whole thing is
-   unused, which can lead to a whole cascade of tricky but logical fallout.
-e) if a destructor is listed as unused, and a constructor isn't, then there's
-   a leak somewhere, and the destructor most likely *should* be called.
-f) there's more actually unused code then what's listed. The idea is that what's
-   listed is definitely unused under the generation configuration, not that
-   it's a list of all unused code. If the count of unused easy hits 0 then
-   we can have a look at the non-easy and if that hits 0, then strip out
-   code from the "release" binaries which only makes sense in debug/dbgutil
-   configurations, and then tackle unused virtual method slots :-)
-
-Symbols that are known to be false alarms are listed in: unusedcode.exclude
