Document WebGPU edge case behaviour of bitfield operations #33
Description
From gpuweb/gpuweb#288
Implementation behaviour edge cases for OpBitFieldSExtract, OpBitFieldUExtract and OpBitFieldInsert are:
- Clamp Offset to [0,31] (make the bit width in bounds)
- Clamp Count such that clamped_offset + count is within [0,31].
- When inserting, only the clamped_count least significant bits are used.
- When extracting, only the clamped_count least significant bits are returned
