Re: luaU_dump() and #define LUAI_FUNC __attribute__((visibility("hidden"))) extern

[Дилян Палаузов <dilyan.palauzov@...>]

Hello,

offering a library means defining an API, that can be used outside of 
the library (regardless how the lib is built).

If luaU_dump and luaP_op[cm]odes are supposed to be used outside of 
liblua, then they shall not be marked with hidden-visibility.

If the symbols are supposed to be used only within the library, then 
luac shall not use them (but the linker can add lopcodes.o to luac, 
apart from -llua).

Having luac that uses symbols, internal for liblua, and exploits the 
fact, that liblua is built statically, where the symbol visibility 
cannot be enforced, hints for a sub-optimal design of the library's 
external API.

Със здраве
