Since the only valid consumer of the DRI drivers is the X.Org xserver,
this changes the default DRI driver directory to match xorg-server:
${libdir}/dri. The old default of /usr/X11R6/modules/dri was wrong for
nearly all current systems.
This commit adds an autoconf macro, MESA_PIC_FLAGS, which sets the
PIC flags according to platform and static/shared setting. The platform
specifics are taken straight from libtool.m4 and stripped down to just
the flags and platforms we cover in Mesa. This should hopefully make it
possible to use autoconf on non-GCC platforms.
The macro is added external to configure.ac in acinclude.m4 since it's
pretty bloated.
Note to BSDers: Previously, x86 defaulted to non-PIC on FreeBSD. I
didn't carry that preference into this macro. Instead, you can just use
--disable-pic where desired.
Mostly some pedantic changes such that `make clean' always ignores
errors. Also changed the top clean target to do the `touch
configs/current' dance instead of realclean.
Currently, there is a single path in src/mesa/Makefile to install that
has a few conditionals in it. This commit changes install to act like
default where we loop over $(DRIVER_DIRS), deciding what to do.
A new target, install-headers, has been broken out to accomodate
installing a standalone OSMesa where neither libGL or gl.pc are wanted.
This is not the same as r3xx indexing. It only tries to protect inputs on
the pixel stack from getting clobbered by temps or texs.
Texs don't need special treatment since they read from special input regs
and write to the same temp regs as ALU/FC instructions.
The default target in src/mesa/Makefile calls a recursive $(MAKE). With
parallel jobs, this causes makedepend to run twice. Instead, block on
the first make until depend has been created.
Consistently cleanup the depend.bak files created by makedepend. Also,
realclean has been changed to use a single find command, which speeds it
up considerably.
When a make target doesn't result in a file of the same name, adding it
to a .PHONY target means make won't look for such a file, speeding the
build up a bit. This allows `make doxygen' to work since otherwise make
will consider the doxygen directory as up to date.
Two fixes to the asm configuration:
- Disable when the user is cross-compiling for x86 or x86_64 since it
requires running an executable compiled for the target host.
- If the user has specified --enable-32-bit on x86_64 or --enable-64-bit
on x86, respect that and choose the correct asm architecture.
