Unable to build x86 hosted debugger for ARM Linux, due to missing target
dependencies. Created ARM Linux specific arm-linux-tdep.c file and moved missing code into it from arm-linux-nat.c. 2000-04-05 Scott Bambrough <scottb@netwinder.org> * arm-linux-tdep.c: New file. * arm-linux-nat.c (fetch_fpregs): Remove unused code. (arm_get_longjmp_target): Moved it and all defines it uses to arm-linux-tdep.c. (arm_linux_extract_return_value): Moved to arm-linux-tdep.c. * config/arm/linux.mt: Add arm-linux-tdep.c to TDEPFILES.
