2002-11-09* i386-linux-nat.c (ORIG_EAX): Define to -1 if not alreadyMark Kettenis1-137/+61
defined. (regmap): Extend to cover all registers. (PT_READ_U, PT_WRITE_U, PTRACE_XFER_TYPE, OLD_CANNOT_FETCH_REGISTERS, OLD_CANNOT_STORE_REGISTERS): Remove definitions. (fetch_register, sore_register): Simplify. (old_fetch_inferior_registers, old_store_inferior_registers): Remove functions. (cannot_fetch_register, cannot_store_register): Change implementation to use regmap array to decide which registers cannot be fetched/stored. This removes $orig_eax from the registers that cannot be fetched/stored. (fetch_inferior_registers): Call fetch_register directly instead of calling old_fetch_inferior_registers. (store_inferior_registers): Call store_register directly instead of calling old_store_inferior_registers. (i386_linux_dr_get): Replace PT_READ_U with PTRACE_PEEKUSER.

* i386-linux-nat.c: Use elf_gregset_t and elf_fpregset_t instead of gregset_t and fpregset_t. Those are the only names that are guaranteed to specify the right types for all supported Linux systems out there. Various doc fixes and gratitious local variable renames, all in an attempt to stress similarities between the code and unify the terminology used. Use ISO-C all over. (regmap): Remove trailing comma. (FPREG_ADDR): Renamed from FPREGSET_T_FPREG_ADDR. (convert_to_gregset): Make static. Remove GDB_REGS argument. It is unnecessary and wasn't used anyway. All callers changed. (convert_to_fpregset, convert_to_xfpregset): Likewise. (fetch_regs, store_regs): Remove unused variable `regno'. (fill_fpregs): If REGNO is not -1, only update the specified register. (fetch_core_registers): Renamed from i386_linux_fetch_core_registers. There is no need for a unique name since the function is static anyway. (linux_elf_core_fns): Renamed from i386_linux_nat_core_functions since it is more descriptive.
