This patch improves the handling of 64-bit parameters in syscalls on ARM. The ARM EABI mandates that 64-bit quantities be passed in even/odd register pairs, which requires special treatment. This allows us to simplify our implementations of pread() and pwrite() and remove the C stubs for pread64() and pwrite64(). Also add ftruncate64() to <unistd.h> Change-Id: I407e2fd223ba0093dd2d0b04c6152fadfc9ce3ef Bug 3107933

# this file is used to list all the syscalls that will be supported by
|
|
# the Bionic C library. It is used to automatically generate the syscall
|
|
# stubs, the list of syscall constants (__NR_xxxx) and the content of <linux/_unitsd.h>
|
|
#
|
|
# each non comment line has the following format:
|
|
#
|
|
# return_type func_name[:syscall_name[:call_id]]([parameter_list]) (#syscall_number|stub)
|
|
#
|
|
# note that:
|
|
# - syscall_name correspond to the name of the syscall, which may differ from
|
|
# the exported function name (example: the exit syscall is implemented by the _exit()
|
|
# function, which is not the same as the standard C exit() function which calls it)
|
|
# The call_id parameter, given that func_name and syscall_name have
|
|
# been provided, allows the user to specify dispatch style syscalls.
|
|
# For example, socket() syscall on i386 actually becomes:
|
|
# socketcall(__NR_socket, 1, *(rest of args on stack)).
|
|
#
|
|
# - each parameter type is assumed to be stored on 32 bits, there is no plan to support
|
|
# 64-bit architectures at the moment
|
|
#
|
|
# - it there is "stub" instead of a syscall number, the tool will not generate any
|
|
# assembler template for the syscall; it's up to the bionic implementation to provide
|
|
# a relevant C stub
|
|
#
|
|
# - additionally, if the syscall number is different amoung ARM, x86 and SuperH, use:
|
|
# return_type funcname[:syscall_name](parameters) arm_number,x86_number,superh_number
|
|
#
|
|
# the file is processed by a python script named gensyscalls.py
