[Mesa-dev] [PATCH 03/11] tgsi: fix the documentation of DLDEXP

[Nicolai Hähnle]

From: Nicolai Hähnle <nicolai.haehnle at amd.com>

Sourcing the exponent for the zw destination pair from Z is consistent
with both tgsi_exec and gallivm. In practice, st_glsl_to_tgsi always
generates per-channel instructions anyway.
