Here are two points on the build process that we'd like your input on:
1. The Makefile assumes gcc. So we might as well use all gcc-specific flags
to get a better Lua core and interpreter, for some definition of "better".
For instance, -fomit-frame-pointer seems to generate smaller and faster
binaries, but a Lua library compiled with -fomit-frame-pointer might not
be debuggable. Is this really a bad thing? Or will anyone needing to debug
the Lua library add the source code to the project and thus not rely on
whatever pre-built Lua exists in their system?
Totally, plus it's fading away with x64.
What gcc-specific flags
should we use if we go that way?
i686, wouldn't anybody working with something smaller be a pro who
knows what he is doing and have no problem fixing the flags?
2. The file all.c (aka one.c) allows Lua to be built as a single object file,
and allows the compiler to generate better code and with just the Lua API
as public symbols. We are considering building Lua in this way, so that
liblua.a will consist of a single object file. Does anyone see a drawback
to this?
Not at all, compile times can't be killing anymore for this
