* LoongArch: Use "$fcsr0" instead of "$r0" in _FPU_{GET,SET}CW HEAD masterXi Ruoyao2 days1-2/+2
| | | | | | | | | | | | Clang inline-asm parser does not allow using "$r0" in movfcsr2gr/movgr2fcsr, so everything using _FPU_{GET,SET}CW is now failing to build with Clang on LoongArch. As we now requires Binutils >= 2.41 which supports using "$fcsr0" here, use it instead of "$r0" to fix the issue.

* Implement C23 log2p1Joseph Myers10 days39-1/+294
| | | | | | | | | | | | | | | | | | | | | | | | C23 adds various <math.h> function families originally defined in TS 18661-4. Add the log2p1 functions (log2(1+x): like log1p, but for base-2 logarithms). This illustrates the intended structure of implementations of all these function families: define them initially with a type-generic template implementation. If someone wishes to add type-specific implementations, it is likely such implementations can be both faster and more accurate than the type-generic one and can then override it for types for which they are implemented (adding benchmarks would be desirable in such cases to demonstrate that a new implementation is indeed faster). The test inputs are copied from those for log1p. Note that these changes make gen-auto-libm-tests depend on MPFR 4.2 (or later). The bulk of the changes are fairly generic for any such new function. (sysdeps/powerpc/nofpu/Makefile only needs changing for those type-generic templates that use fabs.) Tested for x86_64 and x86, and with build-many-glibcs.py.

| | | | | | | | | | | | | | | | | | | | Previously many routines used * to load from vector types stored in the data table. This is emitted as ldr, which byte-swaps the entire vector register, and causes bugs for big-endian when not all lanes contain the same value. When a vector is to be used this way, it has been replaced with an array and the load with an explicit ld1 intrinsic, which byte-swaps only within lanes. As well, many routines previously used non-standard GCC syntax for vector operations such as indexing into vectors types with [] and assembling vectors using {}. This syntax should not be mixed with ACLE, as the former does not respect endianness whereas the latter does. Such examples have been replaced with, for instance, vcombine_* and vgetq_lane* intrinsics. Helpers which only use the GCC syntax, such as the v_call helpers, do not need changing as they do not use intrinsics. Reviewed-by: Szabolcs Nagy <szabolcs.nagy@arm.com>

However, it does not take into consideration if the same tunable is set multiple times, where parse_tunables_string appends the found tunable without checking if it was already in the list. It leads to a stack-based buffer overflow if the tunable is specified more than the total number of tunables. For instance: GLIBC_TUNABLES=glibc.malloc.check=2:... (repeat over the number of total support for different tunable). Instead, use the index of the tunable list to get the expected tunable entry. Since now the initial list is zero-initialized, the compiler might emit an extra memset and this requires some minor adjustment on some ports. Checked on x86_64-linux-gnu and aarch64-linux-gnu.

Hardware floating point toolchain builds are enabled by passing the machine specific argument -mhard-float to gcc via CFLAGS. With this enabled GCC generates floating point instructions for single-precision operations and exports __or1k_hard_float__. There are 2 main parts to this patch. - Implement fenv functions to update the FPCSR flags keeping it in sync with sfp (software floating point). - Update machine context functions to store and restore the FPCSR state. *On mcontext_t ABI* This patch adds __fpcsr to mcontext_t. This is an ABI change, but also an ABI fix. The Linux kernel has always defined padding in mcontext_t that space was missing from the glibc ABI. In Linux this unused space has now been re-purposed for storing the FPCSR. This patch brings OpenRISC glibc in line with the Linux kernel and other libc implementation (musl). Compatibility getcontext, setcontext, etc symbols have been added to allow for binaries expecting the old ABI to continue to work. *Hard float ABI* The calling conventions and types do not change with OpenRISC hard-float so glibc hard-float builds continue to use dynamic linker /lib/ld-linux-or1k.so.1. *Testing* I have tested this patch both with hard-float and soft-float builds and the test results look fine to me.

This ensures that memcpy and mempcpy won't pull in __chk_fail and the routines it calls. Reported-by: Florian Weimer <fweimer@redhat.com> Signed-off-by: Gabi Falk <gabifalk@gmx.com> Reviewed-by: H.J.

* time: Allow later version licensing.Carlos O'Donell2024-05-012-2/+2
| | | | | | | | | | | | | | | The FSF's Licensing and Compliance Lab noted a discrepancy in the licensing of several files in the glibc package. When timespect_get.c was impelemented the license did not include the standard ", or (at your option) any later version." text. Change the license in timespec_get.c and all copied files to match the expected license. This change was previously approved in principle by the FSF in RT ticket #1316403. And a similar instance was fixed in commit 46703efa02f6ddebce5ee54c92f7c32598de0de6.
