* Unify umount function implementations (bug 16552).Joseph Myers2018-03-269-133/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linux kernel architectures have various arrangements for umount syscalls. There is a syscall that takes flags, and an older one that does not. Newer architectures have only the one taking flags, under the name umount2 (or under the name umount, in the ia64 case). Older architectures may have both, under the names umount2 and umount (or under the names umount and oldumount, in the alpha case). glibc then has several similar implementations of the umount function (no flags) in terms of either the __umount2 function, or the corresponding syscall, or in terms of the old syscall under either of its names. This patch simplifies the implementations in glibc by always using the __umount2 function to implement the umount function on all systems using the Linux kernel. The linux/generic implementation is moved to sysdeps/unix/sysv/linux (without any changes to code or comments) and all the other variants are removed. (This will have the effect of causing the new syscall to be used in some cases that previously used the old one, but as discussed for previous changes, such a change to the underlying syscalls used is OK.) There remain two variants of how the __umount2 function is implemented, either in umount2.S, or, for ia64, in syscalls.list. Tested with build-many-glibcs.py. [BZ #16552] * sysdeps/unix/sysv/linux/generic/umount.c: Move to .... * sysdeps/unix/sysv/linux/umount.c: ... here. * sysdeps/unix/sysv/linux/arm/umount.c: Remove file. * sysdeps/unix/sysv/linux/hppa/umount.c: Likewise. * sysdeps/unix/sysv/linux/ia64/umount.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/umount.c: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/umount.c: Likewise. * sysdeps/unix/sysv/linux/umount.S: Likewise. * sysdeps/unix/sysv/linux/x86_64/umount.c: Likewise.

* Use x86_64 backtrace as generic version.Joseph Myers2018-03-2112-200/+115
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | No glibc configuration uses the present debug/backtrace.c, whereas several #include the x86_64 version. The x86_64 version is effectively a generic one (using _Unwind_Backtrace from libgcc, which works much more reliably than the built-in functions used by debug/backtrace.c). This patch moves it to debug/backtrace.c and removes all the #includes of the x86_64 version from other architectures which are no longer required. I do not know whether all the other architecture-specific backtrace implementations that are based on _Unwind_Backtrace are required, or whether, where their differences from the generic version do something useful, suitable hooks could be added to the generic version to reduce the duplication involved. Tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by this patch. * sysdeps/x86_64/backtrace.c: Move to .... * debug/backtrace.c: ... here. * sysdeps/aarch64/backtrace.c: Remove file. * sysdeps/alpha/backtrace.c: Likewise. * sysdeps/hppa/backtrace.c: Likewise. * sysdeps/ia64/backtrace.c: Likewise. * sysdeps/mips/backtrace.c: Likewise. * sysdeps/nios2/backtrace.c: Likewise. * sysdeps/riscv/backtrace.c: Likewise. * sysdeps/sh/backtrace.c: Likewise. * sysdeps/tile/backtrace.c: Likewise.
* Remove powerpc, sparc fdim inlines (bug 22987).Joseph Myers2018-03-203-71/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The powerpc and sparc bits/mathinline.h include inlines of fdim and fdimf. These are not restricted to -fno-math-errno, but do not set errno, and wrongly use ordered <= comparisons instead of the required islessequal comparisons (this latter issue is latent on powerpc because GCC wrongly uses unordered comparison instructions for operations that should use ordered comparison instructions). Since we wish to avoid such header inlines anyway, leaving it to the compiler to inline such standard functions under appropriate conditions, this patch fixes those issues by removing the inlines in question (and thus removing the sparc bits/mathinline.h header which had no other inlines left in it). I've filed <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85003> for adding correct fdim inlines to GCC, since the function is simple enough that a correct inline is a perfectly reasonable architecture-independent optimization with -fno-math-errno and in the absence of implicit excess precision. Tested with build-many-glibcs.py for all its powerpc and sparc configurations. [BZ #22987] * sysdeps/powerpc/bits/mathinline.h (fdim): Remove inline function. (fdimf): Likewise. * sysdeps/sparc/fpu/bits/mathinline.h: Remove file.
* Fix signed integer overflow in random_r (bug 17343).Joseph Myers2018-03-202-5/+10
| | | | | | | | | | | | | | | | | Bug 17343 reports that stdlib/random_r.c has code with undefined behavior because of signed integer overflow on int32_t. This patch changes the code so that the possibly overflowing computations use unsigned arithmetic instead. Note that the bug report refers to "Most code" in that file. The places changed in this patch are the only ones I found where I think such overflow can occur. Tested for x86_64 and x86. [BZ #17343] * stdlib/random_r.c (__random_r): Use unsigned arithmetic for possibly overflowing computations.

The changes are essentially the same as for the narrowing add functions, so the description of those generally applies to this patch as well.

* Remove sysdeps/x86/fpu/bits/mathinline.h __finite inline.Joseph Myers2018-03-162-13/+3
| | | | | | | | | | | | | | | | | | | | | | | Continuing the removals of inline functions from the x86 bits/mathinline.h, this patch removes an inline of __finite (which was not actually architecture-specific at all beyond its endianness-dependence). This inline is not normally used with GCC 4.4 or later, because isfinite now uses __builtin_isfinite except for -fsignaling-nans. Allowing __builtin_isfinite etc. to work properly even for -fsignaling-nans, by implementing versions of those built-in functions that use integer arithmetic in GCC, is <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66462> (a patch was committed but had to be reverted because it caused problems, and that patch didn't address all formats for all architectures, only some, so by itself would not have been sufficient to allow glibc to use __builtin_isfinite unconditionally for new-enough GCC). Tested for x86_64 and x86. * sysdeps/x86/fpu/bits/mathinline.h [__USE_MISC] (__finite): Remove inline function.

* Add support for sqrt asm redirectsWilco Dijkstra2018-03-1510-3/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch series cleans up the many uses of __ieee754_sqrt(f/l) in GLIBC. The goal is to enable GCC to do the inlining, and if this fails call the __ieee754_sqrt function. This is done by internally declaring sqrt with asm redirects. The compat symbols and sqrt wrappers need to disable the redirect. The redirect is also disabled if there are already redirects defined when using -ffinite-math-only. All math functions (but not math tests, non-library code and libnldbl) are built with -fno-math-errno which means GCC will typically inline sqrt as a single instruction. This means targets are no longer forced to add a special inline for sqrt. * include/math.h (sqrt): Declare with asm redirect. (sqrtf): Likewise. (sqrtl): Likewise.

* Remove more old-compilers parts of sysdeps/x86/fpu/bits/mathinline.h.Joseph Myers2018-03-152-183/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes further parts of sysdeps/x86/fpu/bits/mathinline.h that are only of value for optimization with older compiler versions, in accordance with general principles of preferring the let the compiler deal with such inlining through built-in functions. In general, GCC supports inlining all these functions as of version 4.3 or earlier. However, some inlines in GCC may have had excessively restrictive conditions in past GCC versions (e.g. requiring -ffast-math when the inline is valid under broader conditions). (In particular, GCC had, before GCC 7, unnecessarily restrictive conditions on when it could apply floor and ceil inlines corresponding to the ones removed here. The same was true for rint, but bits/mathinline.h *also* was excessively restrictive there.) The removed sincos inlines are for __sincos etc. functions (not a public interface and not currently used in this header either; not in a part of the header ever used for building glibc itself). Likewise, the atan2 inlines included one for __atan2l, also not a public interface and not used for building glibc itself (calls inside glibc generally use __ieee754_atan2l, for which there is a separate __LIBC_INTERNAL_MATH_INLINES case in this header). Tested for x86_64 and x86. * sysdeps/x86/fpu/bits/mathinline.h [__FAST_MATH__] (__sincos_code): Remove define and undefine. [__FAST_MATH__] (__sincos): Remove inline function.
