Detailed Description

Type of the lane dispatch table.

Note

EMBED_TABLE_LAYOUT asserts the thirteen members sit at consecutive EMBED_FUNCTION_POINTER_BYTES offsets, with nothing else.

Eight of the first ten return lane masks. sub7 returns seven bit values and xor_ a whole word.

count, first and last return positions instead of words.

first and last mean first and last in memory order, as the endian binding below delivers.

xor_ carries a trailing underscore because xor is an alternative form of an operator in C++.
