The pointer to the jump table is passed to the application in a machine-dependent way. PowerPC, ARM, MIPS, Blackfin and Nios II architectures use a dedicated register to hold the pointer to the - 'global_data' structure: r2 on PowerPC, r8 on ARM, k0 on MIPS, + 'global_data' structure: r2 on PowerPC, r9 on ARM, k0 on MIPS, P3 on Blackfin and gp on Nios II. The x86 architecture does not use such a register; instead, the pointer to the 'global_data' structure is passed as 'argv[-1]' pointer.
