Question

Is there a way to determine if the executable uses linux soft float on an ARM processor?

Thanks Ben

Answer 1

Depending on the version of ARM ABI (EABI) for ARM, processor-specific flags exist that indicate floating-point behavior in the e_flagsheader ELF.

From Linux / arch / arm / include / asm / elf.h

#define EF_ARM_SOFT_FLOAT       0x00000200      /* ABI 0 */

EF_ARM_SOFT_FLOAT - use instructions FP (0) libcalls (1)

There are programs like readelf that can be used to display information about ELF files.

- /sys /proc, , , /, .
