The s3tc-teximage test seems fixed by the two line change I put in
gallium-util-format-is-supported.
s3tc-texsubimage prints:
Mesa: User error: GL_INVALID_VALUE in glTexSubImage2D
They are not passing for me with current master and a 32-bit system:
Here are the failures:
Testing util_format_dxt1_rgb_pack_8unorm ...
FAILED: f2 d7 90 20 ae 2c 6f 97 obtained
f2 d7 b0 20 ae 2c 6f 97 expected
Testing util_format_dxt5_rgba_pack_8unorm ...
FAILED: f7 10 c5 0c 9a 73 b4
For instance, the DXT1 test is wrong.
The red values used are:
33
93
153
214
99 - 33 = 60
153 - 93 = 60
214 - 153 = 61
213 should be used instead (i.e. 0xd5 instead 0xd6)

Are you sure about this?
I've tried doing it, and it turns out that basically every Gallium
module needs this initialized.
For instance:

So far, there are no dependencies on Gallium in core Mesa.
We've talked about refactoring some of the Gallium code into a separate
module that'd be sharable between Gallium and Mesa. The format code would
probably fit into that.
Can't we just unconditionally pull gallium/auxiliary in Mesa?

This whole thing was done to fix the u_gctors.cpp issue, originally
done by me, sent out without full testing since I saw duplicate work
being done, and then merged by Roland if I recall correctly.
I probably should not have fixed s3tc/util_format like it was done for

The half float conversion code initially used a global C++ constructor
to initialize the tables.
That fails to work since ld does not get the symbol from the shared
library, so I changed to use register a global constructor from C,
using GCC- or MSVC-specific code.
This is not necessarily the

I'd like to add that u_atomic.h already requires either GCC, MSVC or
Solaris, and GCC and MSVC are already supported by this system.
Thus we do indeed now have a simple way to do global constructors,
that only removes support for non-GCC Solaris until someone figures
out how to do that.
