[Mesa-dev] [PATCH 0/5] Vulkan: add extensions numbers to generated enums

[Lionel Landwerlin]

Hi,

We already have seen extensions like VK_IMG_format_pvrtc introduce new
formats. The way the Vulkan specification seems to deal with new
formats is to place them at an offset based on the associated
extension number.

The anv driver currently stores the formats in an array indexed by the
format id. This is kind of convenient and avoids really long switch
statements. Unfortunately new formats with id numbers well beyong
10000000 mean we cannot keep on doing this.

This series introduce new generated defines for extension numbers so
we can deal with those new id using an indirection table based off the
extension number. The first 3 patches are just rework, the generated
defines are in patch 4 and associated helpers in patch 5.

Cheers,
