Therefore, on most architectures, a find-first-bit-set instruction is used to find the highest priority bit set in one of five 32-bit words (for the 140 priorities).

因此，在大部分体系架构上，会使用一条find - first - bit - set指令在5个32位的字(140个优先级)中哪一位的优先级最高。

Note that the. Neon suffix can be used with the. Arm suffix too (used to specify the 32-bit arm instruction set for non-NEON instructions), but must appear after it.

注意。neon后缀可以同时使用。arm后缀(用于指明对非neon指令的32位arm指令集)，但必须出现在后面。

ARM has two instruction modes, and the least-significant bit of the address is used to indicate which mode a given function USES.

ARM有两个指令模式和地址的最低显著位用于指示哪个模式的给定函数使用。
