Subject: main: Fix block index when mixing UBO and SSBO blocks
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=74553240301c60e3520fb55e09391993dac28f5d;p=mesa.git

main: Fix block index when mixing UBO and SSBO blocks

Since we store both in UniformBlocks, we can't just compute the index by
subtracting the array address start, we need to count the number of
buffers of the approriate type.

v2:
  - Just fall back to calc_resource_index (Tapani)
