The generic sysdep.h defines basically two things: 1. Define __NR_pread and __NR_write to __NR_pread64 and __NR_write64 respectively for 64-bits architectures 2. Define the __ALIGNMENT_ARG and __ALIGNMENT_COUNT macros to use for 64-bit argument passing on syscalls. The p{read,write} definition is safe since for 64-bits the p{read,write} will aliased to p{read,write}64. The __ALIGNMENT_{ARG,COUNT} should be safe if all the ABI correctly defines __ASSUME_ALIGNED_REGISTER_PAIRS. This lead to the correct definition on the missing ABIs, mips64-n32 and x32. Checked on x86_64, i386, aarch64, armhf, and ppc64le. * sysdeps/unix/sysv/linux/alpha/sysdep.h: Include generic sysdep.h. * sysdeps/unix/sysv/linux/arm/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/hppa/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/i386/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/ia64/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/m68k/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/microblaze/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n32/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/sh/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/sparc/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/x86_64/sysdep.h: Likewise. * sysdeps/unix/sysv/linux/x86_64/kernel-features.h [__ILP32] (__ASSUME_WORDSIZE64_ILP32): Define. * sysdeps/unix/sysv/linux/mips/kernel-features.h [_MIPS_SIM == _ABIN32] (__ASSUME_WORDSIZE64_ILP32): Likewise. --- sysdeps/unix/sysv/linux/alpha/sysdep.h | 1 + sysdeps/unix/sysv/linux/arm/sysdep.h | 2 ++ sysdeps/unix/sysv/linux/hppa/sysdep.h | 1 + sysdeps/unix/sysv/linux/i386/sysdep.h | 1 + sysdeps/unix/sysv/linux/ia64/sysdep.h | 1 + sysdeps/unix/sysv/linux/m68k/sysdep.h | 1 + sysdeps/unix/sysv/linux/microblaze/sysdep.h | 1 + sysdeps/unix/sysv/linux/mips/kernel-features.h | 6 ++++++ sysdeps/unix/sysv/linux/mips/mips32/sysdep.h | 1 + sysdeps/unix/sysv/linux/mips/mips64/n32/sysdep.h | 1 + sysdeps/unix/sysv/linux/mips/mips64/n64/sysdep.h | 1 + sysdeps/unix/sysv/linux/powerpc/powerpc32/sysdep.h | 1 + sysdeps/unix/sysv/linux/powerpc/powerpc64/sysdep.h | 1 + sysdeps/unix/sysv/linux/s390/s390-32/sysdep.h | 1 + sysdeps/unix/sysv/linux/s390/s390-64/sysdep.h | 1 + sysdeps/unix/sysv/linux/sh/sysdep.h | 1 + sysdeps/unix/sysv/linux/sparc/sysdep.h | 1 + sysdeps/unix/sysv/linux/x86_64/kernel-features.h | 6 ++++++ sysdeps/unix/sysv/linux/x86_64/sysdep.h | 1 + 20 files changed, 52 insertions(+) diff --git a/sysdeps/unix/sysv/linux/alpha/sysdep.h b/sysdeps/unix/sysv/linux/alpha/sysdep.h index b6efc66..d6a1ac9 100644 --- a/sysdeps/unix/sysv/linux/alpha/sysdep.h +++ b/sysdeps/unix/sysv/linux/alpha/sysdep.h @@ -27,6 +27,7 @@ /* There is some commonality. */ #include #include +#include #include diff --git a/sysdeps/unix/sysv/linux/arm/sysdep.h b/sysdeps/unix/sysv/linux/arm/sysdep.h index 3986547..a71b418 100644 --- a/sysdeps/unix/sysv/linux/arm/sysdep.h +++ b/sysdeps/unix/sysv/linux/arm/sysdep.h @@ -21,8 +21,10 @@ #define _LINUX_ARM_SYSDEP_H 1 /* There is some commonality. */ +#include #include #include +#include /* Defines RTLD_PRIVATE_ERRNO and USE_DL_SYSINFO. */ #include diff --git a/sysdeps/unix/sysv/linux/hppa/sysdep.h b/sysdeps/unix/sysv/linux/hppa/sysdep.h index b459f0a..7b43695 100644 --- a/sysdeps/unix/sysv/linux/hppa/sysdep.h +++ b/sysdeps/unix/sysv/linux/hppa/sysdep.h @@ -24,6 +24,7 @@ #include #include #include +#include /* Defines RTLD_PRIVATE_ERRNO. */ #include diff --git a/sysdeps/unix/sysv/linux/i386/sysdep.h b/sysdeps/unix/sysv/linux/i386/sysdep.h index 5fcb175..8776d8e 100644 --- a/sysdeps/unix/sysv/linux/i386/sysdep.h +++ b/sysdeps/unix/sysv/linux/i386/sysdep.h @@ -22,6 +22,7 @@ /* There is some commonality. */ #include #include +#include /* Defines RTLD_PRIVATE_ERRNO and USE_DL_SYSINFO. */ #include #include diff --git a/sysdeps/unix/sysv/linux/ia64/sysdep.h b/sysdeps/unix/sysv/linux/ia64/sysdep.h index 8dfc582..9b95454 100644 --- a/sysdeps/unix/sysv/linux/ia64/sysdep.h +++ b/sysdeps/unix/sysv/linux/ia64/sysdep.h @@ -22,6 +22,7 @@ #include #include +#include #include #include #include diff --git a/sysdeps/unix/sysv/linux/m68k/sysdep.h b/sysdeps/unix/sysv/linux/m68k/sysdep.h index ce48496..ff4dea0 100644 --- a/sysdeps/unix/sysv/linux/m68k/sysdep.h +++ b/sysdeps/unix/sysv/linux/m68k/sysdep.h @@ -18,6 +18,7 @@ . */ #include +#include #include /* Defines RTLD_PRIVATE_ERRNO. */ diff --git a/sysdeps/unix/sysv/linux/microblaze/sysdep.h b/sysdeps/unix/sysv/linux/microblaze/sysdep.h index abc13c2..f06aa1b 100644 --- a/sysdeps/unix/sysv/linux/microblaze/sysdep.h +++ b/sysdeps/unix/sysv/linux/microblaze/sysdep.h @@ -22,6 +22,7 @@ #include #include #include +#include /* Defines RTLD_PRIVATE_ERRNO. */ #include diff --git a/sysdeps/unix/sysv/linux/mips/kernel-features.h b/sysdeps/unix/sysv/linux/mips/kernel-features.h index ea6a914..17ab696 100644 --- a/sysdeps/unix/sysv/linux/mips/kernel-features.h +++ b/sysdeps/unix/sysv/linux/mips/kernel-features.h @@ -53,3 +53,9 @@ #if _MIPS_SIM == _ABIO32 #
