+ /* When breaking down a [reg+index] reload address into [(reg+high)+low],
+ of which the (reg+high) gets turned into a reload add insn,
+ we try to decompose the index into high/low values that can often
+ also lead to better reload CSE.
+ For example:
+ ldr r0, [r2, #4100] // Offset too large
+ ldr r1, [r2, #4104] // Offset too large
+
+ is best reloaded as:
+ add t1, r2, #4096
+ ldr r0, [t1, #4]
+ add t2, r2, #4096
+ ldr r1, [t2, #8]
+
+ which post-reload CSE can simplify in most cases to eliminate the
+ second add instruction:
+ add t1, r2, #4096
+ ldr r0, [t1, #4]
+ ldr r1, [t1, #8]
+
+ The idea here is that we want to split out the bits of the constant
+ as a mask, rather than as subtracting the maximum offset that the
+ respective type of load/store used can handle.
+
+ When encountering negative offsets, we can still utilize it even if
+ the overall offset is positive; sometimes this may lead to an immediate
+ that can be constructed with fewer instructions.
+ For example:
+ ldr r0, [r2, #0x3FFFFC]
+
+ This is best reloaded as:
+ add t1, r2, #0x400000
+ ldr r0, [t1, #-4]
+
+ The trick for spotting this for a load insn with N bits of offset
+ (i.e. bits N-1:0) is to look at bit N; if it is set, then chose a
+ negative offset that is going to make bit N and all the bits below
+ it become zero in the remainder part.
+
+ The SIGN_MAG_LOW_ADDR_BITS macro below implements this, with respect
+ to sign-magnitude addressing (i.e. separate +- bit, or 1's complement),
+ used in most cases of ARM load/store instructions. */
