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.
