+ floating-point registers, and are implemented by the arrays
+ dbx_register_map[] and svr4_dbx_register_map in
+ gcc/config/i386.c. GCC also defines a third numbering scheme in
+ gcc/config/i386.c, which it designates as the "default" register
+ map used in 64bit mode. This last register numbering scheme is
+ implemented in dbx64_register_map, and is used for AMD64; see
+ amd64-tdep.c.
+
+ Currently, each GCC i386 target always uses the same register
+ numbering scheme across all its supported debugging formats
+ i.e. SDB (COFF), stabs and DWARF 2. This is because
+ gcc/sdbout.c, gcc/dbxout.c and gcc/dwarf2out.c all use the
+ DBX_REGISTER_NUMBER macro which is defined by each target's
+ respective config header in a manner independent of the requested
+ output debugging format.
+
+ This does not match the arrangement below, which presumes that
+ the SDB and stabs numbering schemes differ from the DWARF and
+ DWARF 2 ones. The reason for this arrangement is that it is
+ likely to get the numbering scheme for the target's
+ default/native debug format right. For targets where GCC is the
+ native compiler (FreeBSD, NetBSD, OpenBSD, GNU/Linux) or for
+ targets where the native toolchain uses a different numbering
+ scheme for a particular debug format (stabs-in-ELF on Solaris)
