+/* This code is to handle mapping symbols as defined in the ARM ELF spec.
+ (This text is taken from version B-02 of the spec):
+
+ 4.4.7 Mapping and tagging symbols
+
+ A section of an ARM ELF file can contain a mixture of ARM code,
+ Thumb code, and data. There are inline transitions between code
+ and data at literal pool boundaries. There can also be inline
+ transitions between ARM code and Thumb code, for example in
+ ARM-Thumb inter-working veneers. Linkers, machine-level
+ debuggers, profiling tools, and disassembly tools need to map
+ images accurately. For example, setting an ARM breakpoint on a
+ Thumb location, or in a literal pool, can crash the program
+ being debugged, ruining the debugging session.
+
+ ARM ELF entities are mapped (see section 4.4.7.1 below) and
+ tagged (see section 4.4.7.2 below) using local symbols (with
+ binding STB_LOCAL). To assist consumers, mapping and tagging
+ symbols should be collated first in the symbol table, before
+ other symbols with binding STB_LOCAL.
+
+ To allow properly collated mapping and tagging symbols to be
+ skipped by consumers that have no interest in them, the first
+ such symbol should have the name $m and its st_value field equal
+ to the total number of mapping and tagging symbols (including
+ the $m) in the symbol table.
+
+ 4.4.7.1 Mapping symbols
+
+ $a Labels the first byte of a sequence of ARM instructions.
+ Its type is STT_FUNC.
+
+ $d Labels the first byte of a sequence of data items.
+ Its type is STT_OBJECT.
+
+ $t Labels the first byte of a sequence of Thumb instructions.
+ Its type is STT_FUNC.
+
+ This list of mapping symbols may be extended in the future.
+
+ Section-relative mapping symbols
+
+ Mapping symbols defined in a section define a sequence of
+ half-open address intervals that cover the address range of the
+ section. Each interval starts at the address defined by a
+ mapping symbol, and continues up to, but not including, the
+ address defined by the next (in address order) mapping symbol or
+ the end of the section. A corollary is that there must be a
+ mapping symbol defined at the beginning of each section.
+ Consumers can ignore the size of a section-relative mapping
+ symbol. Producers can set it to 0.
+
+ Absolute mapping symbols
+
+ Because of the need to crystallize a Thumb address with the
+ Thumb-bit set, absolute symbol of type STT_FUNC (symbols of type
+ STT_FUNC defined in section SHN_ABS) need to be mapped with $a
+ or $t.
+
+ The extent of a mapping symbol defined in SHN_ABS is [st_value,
+ st_value + st_size), or [st_value, st_value + 1) if st_size = 0,
+ where [x, y) denotes the half-open address range from x,
+ inclusive, to y, exclusive.
+
+ In the absence of a mapping symbol, a consumer can interpret a
+ function symbol with an odd value as the Thumb code address
+ obtained by clearing the least significant bit of the
+ value. This interpretation is deprecated, and it may not work in
+ the future.
+
+ Note - the Tagging symbols ($b, $f, $p $m) have been dropped from
+ the EABI (which is still under development), so they are not
+ implemented here. */
