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.
