This CL updates the clang format files to have a single shared format between Dawn and Tint. The major changes are tabs are 4 spaces, lines are 100 columns and namespaces are not indented. Bug: dawn:1339 Change-Id: I4208742c95643998d9fd14e77a9cc558071ded39 Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/87603 Commit-Queue: Dan Sinclair <dsinclair@chromium.org> Reviewed-by: Corentin Wallez <cwallez@chromium.org> Kokoro: Kokoro <noreply+kokoro@google.com>

// In Vulkan descriptor pools have to be sized to an exact number of descriptors. This means
|
|
// it's hard to have something where we can mix different types of descriptor sets because
|
|
// we don't know if their vector of number of descriptors will be similar.
|
|
//
|
|
// That's why that in addition to containing the VkDescriptorSetLayout to create
|
|
// VkDescriptorSets for its bindgroups, the layout also acts as an allocator for the descriptor
|
|
// sets.
|
|
//
|
|
// The allocations is done with one pool per descriptor set, which is inefficient, but at least
|
|
// the pools are reused when no longer used. Minimizing the number of descriptor pool allocation
|
|
// is important because creating them can incur GPU memory allocation which is usually an
|
|
// expensive syscall.
