From d62f9ec0cce26a275ec68f4564814041a33395b1 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Tue, 25 Sep 2018 16:50:30 +0000 Subject: Complete sys/procfs.h unification. This patch completes the process of unifying sys/procfs.h headers for architectures using the Linux kernel by making alpha use the generic version. That was previously deferred because alpha has different definitions of prgregset_t and prfpregset_t from other architectures, so changing to the common definitions would change C++ name mangling. To avoid such a change, a header bits/procfs-prregset.h is added, and alpha gets its own version of that header. Tested for x86_64 and x86, and with build-many-glibcs.py. * sysdeps/unix/sysv/linux/sys/procfs.h: Include . (prgregset_t): Define using __prgregset_t. (prfpregset_t): Define using __prfpregset_t. * sysdeps/unix/sysv/linux/Makefile [$(subdir) = misc] (sysdep_headers): Add bits/procfs-prregset.h. * sysdeps/unix/sysv/linux/bits/procfs-prregset.h: New file. * sysdeps/unix/sysv/linux/alpha/bits/procfs-prregset.h: Likewise. * sysdeps/unix/sysv/linux/alpha/bits/procfs.h: Likewise. * sysdeps/unix/sysv/linux/alpha/sys/procfs.h: Remove file. --- sysdeps/unix/sysv/linux/Makefile | 3 +- .../unix/sysv/linux/alpha/bits/procfs-prregset.h | 25 ++++ sysdeps/unix/sysv/linux/alpha/bits/procfs.h | 38 ++++++ sysdeps/unix/sysv/linux/alpha/sys/procfs.h | 127 --------------------- sysdeps/unix/sysv/linux/bits/procfs-prregset.h | 25 ++++ sysdeps/unix/sysv/linux/sys/procfs.h | 6 +- 6 files changed, 94 insertions(+), 130 deletions(-) create mode 100644 sysdeps/unix/sysv/linux/alpha/bits/procfs-prregset.h create mode 100644 sysdeps/unix/sysv/linux/alpha/bits/procfs.h delete mode 100644 sysdeps/unix/sysv/linux/alpha/sys/procfs.h create mode 100644 sysdeps/unix/sysv/linux/bits/procfs-prregset.h (limited to 'sysdeps/unix') diff --git a/sysdeps/unix/sysv/linux/Makefile b/sysdeps/unix/sysv/linux/Makefile index db5b17f..99d71ea 100644 --- a/sysdeps/unix/sysv/linux/Makefile +++ b/sysdeps/unix/sysv/linux/Makefile @@ -41,7 +41,8 @@ sysdep_headers += sys/mount.h sys/acct.h sys/sysctl.h \ bits/socket_type.h bits/syscall.h bits/sysctl.h \ bits/mman-linux.h bits/mman-shared.h bits/ptrace-shared.h \ bits/siginfo-arch.h bits/siginfo-consts-arch.h \ - bits/procfs.h bits/procfs-id.h bits/procfs-extra.h + bits/procfs.h bits/procfs-id.h bits/procfs-extra.h \ + bits/procfs-prregset.h tests += tst-clone tst-clone2 tst-clone3 tst-fanotify tst-personality \ tst-quota tst-sync_file_range tst-sysconf-iov_max tst-ttyname \ diff --git a/sysdeps/unix/sysv/linux/alpha/bits/procfs-prregset.h b/sysdeps/unix/sysv/linux/alpha/bits/procfs-prregset.h new file mode 100644 index 0000000..2f17e62 --- /dev/null +++ b/sysdeps/unix/sysv/linux/alpha/bits/procfs-prregset.h @@ -0,0 +1,25 @@ +/* Types of prgregset_t and prfpregset_t.
