[Mesa-dev] [PATCH v3 00/29] add fp64 support to mesa and glsl compiler

[Ilia Mirkin]

This is v3 of the patchset which includes fixes based on Ian's
feedback with the exception of his comment on patch 23 (glsl: validate
output types for shader stages), i.e. whether it needs to exist at all
and isn't that being checked elsewhere. I am unfortunately not
familiar enough with the overall flow of things yet to work it
out. Perhaps someone else can take a look... Tapani?

Chris also had a suggestion for standardizing the size_mul/dmul/etc
variable names... unfortunately various ones count different
things. Some are 4/8, others are 1/2. I left them as is for now.

If I missed anything from the existing feedback, please let me
know. As before, this passes all current fp64 tests in piglit on nvc0
with the exception of 4 initializer tests which Dave is looking at but
is fairly confident the error is in st/mesa somewhere.
