bits(64) offset = SignExtend(imm19:'00', 64); bits(4) condition = cond;

Assembler Symbols

<cond>

Is one of the standard conditions, encoded in the "cond" field in the standard way.

<label>

Is the program label to be conditionally branched to. Its offset from the address of this instruction, in the range +/-1MB, is encoded as "imm19" times 4.

Operation

if ConditionHolds(condition) then BranchTo(PC[] + offset, BranchType_DIR);
