op

26-bit signed PC-relative branch offset

B <label>

BranchType branch_type = if op == '1' then BranchType_DIRCALL else BranchType_DIR; bits(64) offset = SignExtend(imm26:'00', 64);

Assembler Symbols

<label>

Is the program label to be unconditionally branched to. Its offset from the address of this instruction, in the range +/-128MB, is encoded as "imm26" times 4.

Operation

if branch_type == BranchType_DIRCALL then X[30] = PC[] + 4; BranchTo(PC[] + offset, BranchType_DIR);[] + offset, branch_type);
