Add INTERNAL_SYSCALL_CALL
This patch adds two new macros for internal and inline syscall to use within GLIBC: INTERNAL_SYSCALL_CALL and INLINE_SYSCALL_CALL. They are similar to the old INTERNAL_SYSCALL and INLINE_SYSCALL with the difference the new macros accept a variable argument call and do not require to pass the expected argument size. The advantage is it is possible to use variable argument macros like SYSCALL_LL{64} without the need to also handle the argument size. So for an ABI where SYSCALL_LL might split the argument in high and low parts, instead of: INTERNAL_SYSCALL_DECL (err); #if ... INTERNAL_SYSCALL (syscall, err, 2, SYSCALL_LL (len)); #else INTERNAL_SYSCALL (syscall, err, 1, SYSCALL_LL (len)); #endif It will be just: INTERNAL_SYSCALL_CALL (syscall, err, SYSCALL_LL (len)); The INLINE_SYSCALL_CALL follows the same semanthic regarding the argument and is similar to INLINE_SYSCALL regarding setting errno. Checked with a build for x86_64, i386, aach64, armhf, powerpc64le, powerpc32, and mips32. No code generation changed. * sysdeps/unix/sysdep.h (__INTERNAL_SYSCALL0): New macro.
