+/* The SH cannot load a large constant into a register, constants have to
+ come from a pc relative load. The reference of a pc relative load
+ instruction must be less than 1k infront of the instruction. 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 things bigger.
+
+ Worst case code looks like:
+
+ mov.l L1,rn
+ bra L2
+ nop
+ align
+L1: .long value
+L2:
+ ..
+
+ mov.l L3,rn
+ bra L4
+ nop
+ align
+L3: .long value
+L4:
+ ..
+
+ During shorten_branches we notice the instructions which can have a
+ constant table in them, if we see two that are close enough
+ together, we move the constants from the first table to the second
+ table and continue. This process can happen again and again, and
+ in the best case, moves the constant table outside of the function.
+
+ In the above example, we can tell that L3 is within 1k of L1, so
+ the first move can be shrunk from the 3 insn+constant sequence into
+ just 1 insn, and the constant moved to L3 to make:
+
+ mov.l L1,rn
+ ..
+ mov.l L3,rn
+ bra L4
+ nop
+ align
+L3:.long value
+L4:.long value
+
+ Then the second move becomes the target for the shortening process.
+
+ We keep a simple list of all the constants accumulated in the
+ current pool so there are no duplicates in a single table, but
+ they are not factored into the size estimates.
