The default is to enable (and autodetect based on lscpu) simd support,
or the mode can be specified via --enable-simd=mode. --disable-simd
disables the support but ensures gcc will still compile the float vector
types.
There's still some cleanup to do, but everything seems to be working
nicely: `make -j` works, `make distcheck` passes. There is probably
plenty of bitrot in the package directories (RPM, debian), though.
The vc project files have been removed since those versions are way out
of date and quakeforge is pretty much dependent on gcc now anyway.
Most of the old Makefile.am files are now Makemodule.am. This should
allow for new Makefile.am files that allow local building (to be added
on an as-needed bases). The current remaining Makefile.am files are for
standalone sub-projects.a
The installable bins are currently built in the top-level build
directory. This may change if the clutter gets to be too much.
While this does make a noticeable difference in build times, the main
reason for the switch was to take care of the growing dependency issues:
now it's possible to build tools for code generation (eg, using qfcc and
ruamoko programs for code-gen).
This paves the way for clean initialization of the Vulkan renderer, and
very much cleans up the older renderer initialization code as gl and sw
are no longer intertwined.
Rename TOPDIR to TOPSRC, can't get around requiring it and it's more
descriptive this way anyway. Also, revert the use of the m4_esyscmd()
macro in configure. It's kinda cool, but I'll come up with a better way
to do it.
We need to figure out a way to make docs in unusual places, like in the
SourceForge shell environment -- which doesn't have an extremely recent
autotools. This is an extremely stripped-down automake/autoconf setup that
provides the bare minimum needed to AC_SUBST variables.
It's dirty and hacky, but it kinda works.
Most of the guts of configure.ac have been moved to config.d and are then
brought in by m4_include. This will make maintaining configure.ac much easier.
Also drop use of PROGRAM and VERSION, using PACKAGE_NAME, PACKAGE_VERSION, and
on occasion, PACKAGE_STRING instead, and clean out some old files we no longer
need.
Rather than using an ifdef around the entire code, get autoconf to do the work
for us. For one thing, this allows doxygen to produce decent docs. It also
makes for less compalation when building without support for various formats.
