In the A64 instruction set, there are a few instructions that are truly conditional. Truly conditional means that when the condition is false, the instruction advances the program counter but has no other effect.
The conditional branch,
B. is a truly conditional instruction. The condition code is
appended to the instruction with a '.' delimiter, for example
There are other truly conditional branch instructions that execute depending on the value of the Zero condition flag. You cannot append any condition code suffix to them. These instructions are:
There are a few A64 instructions that are unconditionally executed but use the condition code as a source operand. These instructions always execute but the operation depends on the value of the condition code. These instructions can be categorized as:
In these instructions, you specify the condition code in the final operand position, for
