      syscall overhaul part two - unify public and internal syscall interface · 685e40bb
      Rich Felker 提交于
      with this patch, the syscallN() functions are no longer needed; a
      variadic syscall() macro allows syscalls with anywhere from 0 to 6
      arguments to be made with a single macro name. also, manually casting
      each non-integer argument with (long) is no longer necessary; the
      casts are hidden in the macros.
      
      some source files which depended on being able to define the old macro
      SYSCALL_RETURNS_ERRNO have been modified to directly use __syscall()
      instead of syscall(). references to SYSCALL_SIGSET_SIZE and SYSCALL_LL
      have also been changed.
      
      x86_64 has not been tested, and may need a follow-up commit to fix any
      minor bugs/oversights.

      overhaul syscall interface · d00ff295
      Rich Felker 提交于
      this commit shuffles around the location of syscall definitions so
      that we can make a syscall() library function with both SYS_* and
      __NR_* style syscall names available to user applications, provides
      the syscall() library function, and optimizes the code that performs
      the actual inline syscalls in the library itself.
      
      previously on i386 when built as PIC (shared library), syscalls were
      incurring bus lock (lock prefix) overhead at entry and exit, due to
      the way the ebx register was being loaded (xchg instruction with a
      memory operand). now the xchg takes place between two registers.
      
      further cleanup to arch/$(ARCH)/syscall.h is planned.
