The floating-point ABI used by this object file. The value will be:
0 for files not affected by the floating-point ABI, compatible with the
legacy NaN encoding convention.
1 for files using the hardware floating-point with a standard
double-precision FPU, and using the legacy NaN encoding convention.
2 for files using the hardware floating-point ABI with a single-precision
FPU, and using the legacy NaN encoding convention.
3 for files using the software floating-point ABI, and using the legacy
NaN encoding convention.
4 for files using the hardware floating-point ABI with 64-bit wide
double-precision floating-point registers and 32-bit wide general
purpose registers, and using the legacy NaN encoding convention.
8 for files not affected by the floating-point ABI, compatible with the
IEEE 754-2008 NaN encoding convention.
9 for files using the hardware floating-point with a standard
double-precision FPU, and using the IEEE 754-2008 NaN encoding
convention.
10 for files using the hardware floating-point ABI with a
single-precision FPU, and using the IEEE 754-2008 NaN encoding
convention.
11 for files using the software floating-point ABI, and using the IEEE
754-2008 NaN encoding convention.
12 for files using the hardware floating-point ABI with 64-bit wide
double-precision floating-point registers and 32-bit wide general
purpose registers, and using the IEEE 754-2008 NaN encoding convention.
