* meson: use gnu_symbol_visibility argumentDylan Baker2020-06-011-1/+2
| | | | | | | | | | This uses a meson builtin to handle -fvisibility=hidden. This is nice because we don't need to track which languages are used, if C++ is suddenly added meson just does the right thing.

* gallium/util: Add back (and rename) util_float_to_half implementationRoland Scheidegger2020-03-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | This implementation was removed by 8b8af6d3 ("gallium/util: Switch util_float_to_half to _mesa_float_to_half()'s impl.") It was not actually broken, but _mesa_float_to_half() implements round-to-nearest-even, whereas util_float_to_half() implemented round-to-zero. So rename it appropriately. GL actually never cares about rounding (except a broken piglit test), however d3d10 very much does and requires RTZ for float to half conversion. Moreover, apparently at least radeon gpus actually always do RTZ when doing RT writes (and I'd suspect for shader image writes as well). Hence it seems appropriate to hook up this rtz function to the format instead. This will cause llvmpipe and softpipe to use rtz rounding for clears with half float formats, and softpipe would use rtz behavior for rt writes as well (llvmpipe has that hardcoded), not sure if "real" hw drivers hit this function for much. (For shader opcodes would still need to figure out what rounding to use appropriately, but this is a question for another day.) Note should probably unify with _mesa_float_to_float16_rtz. Unclear at this point which one is better, so just restore previous function here.

* Revert "gallium: Fix big-endian addressing of non-bitmask array formats."Eric Anholt2020-02-111-17/+6
| | | | | | | | | | | | | | | | | | | | | | | | This reverts the functional part of commit d17ff2f7f1864c81c1e00d04baf20f953c6d276a, leaving the unit test for mesa/pipe agreement on what's an array. The issue is that the util_channel_desc.shift values on array formats are not used for bit addressing in memory, they're bit addressing within a word treating a pixel of the format as a native type, as seen by llvmpipe's use of the values to do shifts (see lp_build_unpack_arith_rgba_aos() for example). This means the values are nonsensical for 3-byte RGB, but then llvmpipe doesn't expose those formats so it works out. I still want to clean up our big-endian format handling at some point, but let's fix the s390x regression first, sort out our format unit tests in CI, then be able to refactor with confidence.

* util: Move gallium's PIPE_FORMAT utils to /util/format/Eric Anholt2019-11-1425-0/+11248
To make PIPE_FORMATs usable from non-gallium parts of Mesa, I want to move their helpers out of gallium. Since u_format used util_copy_rect(), I moved that in there, too. I've put it in a separate directory in util/ because it's a big chunk of related code, and it's not clear to me whether we might want it as a separate library from libmesa_util at some point.
