2764 (This text is taken from version B-02 of the spec):
2766 4.4.7 Mapping and tagging symbols
2768 A section of an ARM ELF file can contain a mixture of ARM code,
2769 Thumb code, and data. There are inline transitions between code
2770 and data at literal pool boundaries. There can also be inline
2771 transitions between ARM code and Thumb code, for example in
2772 ARM-Thumb inter-working veneers. Linkers, machine-level
2773 debuggers, profiling tools, and disassembly tools need to map
2774 images accurately. For example, setting an ARM breakpoint on a
2775 Thumb location, or in a literal pool, can crash the program
2776 being debugged, ruining the debugging session.
2778 ARM ELF entities are mapped (see section 4.4.7.1 below) and
2779 tagged (see section 4.4.7.2 below) using local symbols (with
2780 binding STB_LOCAL). To assist consumers, mapping and tagging
2781 symbols should be collated first in the symbol table, before
2782 other symbols with binding STB_LOCAL.
2784 To allow properly collated mapping and tagging symbols to be
2785 skipped by consumers that have no interest in them, the first
2786 such symbol should have the name $m and its st_value field equal
2787 to the total number of mapping and tagging symbols (including
2788 the $m) in the symbol table.
2790 4.4.7.1 Mapping symbols
2792 $a Labels the first byte of a sequence of ARM instructions.
2793 Its type is STT_FUNC.
2795 $d Labels the first byte of a sequence of data items.
2796 Its type is STT_OBJECT.
2798 $t Labels the first byte of a sequence of Thumb instructions.
2799 Its type is STT_FUNC.
2801 This list of mapping symbols may be extended in the future.
2803 Section-relative mapping symbols
2805 Mapping symbols defined in a section define a sequence of
2806 half-open address intervals that cover the address range of the
2807 section. Each interval starts at the address defined by a
2808 mapping symbol, and continues up to, but not including, the
2809 address defined by the next (in address order) mapping symbol or
2810 the end of the section. A corollary is that there must be a
2811 mapping symbol defined at the beginning of each section.
2812 Consumers can ignore the size of a section-relative mapping
2813 symbol. Producers can set it to 0.
2815 Absolute mapping symbols
2817 Because of the need to crystallize a Thumb address with the
2818 Thumb-bit set, absolute symbol of type STT_FUNC (symbols of type
2819 STT_FUNC defined in section SHN_ABS) need to be mapped with $a
2822 The extent of a mapping symbol defined in SHN_ABS is [st_value,
2823 st_value + st_size), or [st_value, st_value + 1) if st_size = 0,
2824 where [x, y) denotes the half-open address range from x,
2825 inclusive, to y, exclusive.
2827 In the absence of a mapping symbol, a consumer can interpret a
2828 function symbol with an odd value as the Thumb code address
2829 obtained by clearing the least significant bit of the
2830 value. This interpretation is deprecated, and it may not work in
2833 Note - the Tagging symbols ($b, $f, $p $m) have been dropped from
2834 the EABI (which is still under development), so they are not
2835 implemented here. */

13052 See if it's a processor-specific option.
13054 This routine is somewhat complicated by the need for backwards
13055 compatibility (since older releases of gcc can't be changed).
13056 The new options try to make the interface as compatible as
13059 New options (supported) are:
13061 -mcpu=<cpu name> Assemble for selected processor
13062 -march=<architecture name> Assemble for selected architecture
13063 -mfpu=<fpu architecture> Assemble for selected FPU.
13064 -EB/-mbig-endian Big-endian
13065 -EL/-mlittle-endian Little-endian
13066 -k Generate PIC code
13067 -mthumb Start in Thumb mode
13068 -mthumb-interwork Code supports ARM/Thumb interworking
13070 For now we will also provide support for:
13072 -mapcs-32 32-bit Program counter
13073 -mapcs-26 26-bit Program counter
13074 -macps-float Floats passed in FP registers
13075 -mapcs-reentrant Reentrant code
13077 (sometime these will probably be replaced with -mapcs=<list of options>
13078 and -matpcs=<list of options>)
13080 The remaining options are only supported for back-wards compatibility.
13081 Cpu variants, the arm part is optional:
13082 -m[arm]1 Currently not supported.
13083 -m[arm]2, -m[arm]250 Arm 2 and Arm 250 processor
13084 -m[arm]3 Arm 3 processor
13085 -m[arm]6[xx], Arm 6 processors
13086 -m[arm]7[xx][t][[d]m] Arm 7 processors
13087 -m[arm]8[10] Arm 8 processors
13088 -m[arm]9[20][tdmi] Arm 9 processors
13089 -mstrongarm[110[0]] StrongARM processors
13090 -mxscale XScale processors
13091 -m[arm]v[2345[t[e]]] Arm architectures
13092 -mall All (except the ARM1)
13094 -mfpa10, -mfpa11 FPA10 and 11 co-processor instructions
13095 -mfpe-old (No float load/store multiples)
13096 -mvfpxd VFP Single precision
13098 -mno-fpu Disable all floating point instructions
