This ++ means that we often have to dump a constant inside a function, and ++ generate code to branch around it. ++ ++ It is important to minimize this, since the branches will slow ++ things down and make the code larger. ++ ++ Normally we can hide the table after an existing unconditional ++ branch so that there is no interruption of the flow, but in the ++ worst case the code looks like this: ++ ++ lddpc rn, L1 ++ ... ++ rjmp L2 ++ align ++ L1: .long value ++ L2: ++ ... ++ ++ lddpc rn, L3 ++ ... ++ rjmp L4 ++ align ++ L3: .long value ++ L4: ++ ... ++ ++ We fix this by performing a scan after scheduling, which notices ++ which instructions need to have their operands fetched from the ++ constant table and builds the table. ++ ++ The algorithm starts by building a table of all the constants that ++ need fixing up and all the natural barriers in the function (places ++ where a constant table can be dropped without breaking the flow). ++ For each fixup we note how far the pc-relative replacement will be ++ able to reach and the offset of the instruction into the function. ++ ++ Having built the table we then group the fixes together to form ++ tables that are as large as possible (subject to addressing ++ constraints) and emit each table of constants after the last ++ barrier that is within range of all the instructions in the group. ++ If a group does not contain a barrier, then we forcibly create one ++ by inserting a jump instruction into the flow.
