+
+ First of all, this relocation is used to calculate the distance
+ between two symbols in the SAME section. It is used for jump-
+ table, debug information, exception table, et al. Therefore,
+ it is a unsigned positive value. It is NOT used for general-
+ purpose arithmetic.
+
+ Consider this example, the distance between .LEND and .LBEGIN
+ is stored at the address of foo.
+
+ ---- >8 ---- >8 ---- >8 ---- >8 ----
+ .data
+ foo:
+ .word .LBEGIN - .LEND
+
+ .text
+ [before]
+ .LBEGIN
+ \
+ [between] distance
+ /
+ .LEND
+ [after]
+ ---- 8< ---- 8< ---- 8< ---- 8< ----
+
+ We use a single relocation entry for this expression.
+ * The initial distance value is stored direcly in that location
+ specified by r_offset (i.e., foo in this example.)
+ * The begin of the region, i.e., .LBEGIN, is specified by
+ r_info/R_SYM and r_addend, e.g., .text + 0x32.
+ * The end of region, i.e., .LEND, is represented by
+ .LBEGIN + distance instead of .LEND, so we only need
+ a single relocation entry instead of two.
+
+ When an instruction is relaxed, we adjust the relocation entry
+ depending on where the instruction locates. There are three
+ cases, before, after and between the region.
+ * between: Distance value is read from r_offset, adjusted and
+ written back into r_offset.
+ * before: Only r_addend is adjust.
+ * after: We don't care about it.
+
+ Hereby, there are some limitation.
+
+ `(.LEND - 1) - .LBEGIN' and `(.LEND - .LBEGIN) - 1'
+ are semantically different, and we cannot handle latter case
+ when relaxation.
+
+ The latter expression means subtracting 1 from the distance
+ between .LEND and .LBEGIN. And the former expression means
+ the distance between (.LEND - 1) and .LBEGIN.
+
+ The nuance affects whether to adjust distance value when relax
+ an instruction. In another words, whether the instruction
+ locates in the region. Because we use a single relocation entry,
+ there is no field left for .LEND and the subtrahend.
+
+ Since GCC-4.5, GCC may produce debug information in such expression
+ .long .L1-1-.L0
+ in order to describe register clobbering during an function-call.
+ .L0:
+ call foo
+ .L1:
+
+ Check http://gcc.gnu.org/ml/gcc-patches/2009-06/msg01317.html
