Other Activity This Week

math: Use tanhf from CORE-MATH
Adhemerval Zanella: The CORE-MATH implementation is correctly rounded (for any rounding mode) and shows slight better performance to the generic tanhf.

math: Use sinhf from CORE-MATH
Adhemerval Zanella: The CORE-MATH implementation is correctly rounded (for any rounding mode) and shows slight better performance to the generic sinhf.

math: Use coshf from CORE-MATH
Adhemerval Zanella: The CORE-MATH implementation is correctly rounded (for any rounding mode), although it should worse performance than current one.

math: Use atanhf from CORE-MATH
Adhemerval Zanella: The CORE-MATH implementation is correctly rounded (for any rounding mode) and shows slight better performance to the generic atanhf.

math: Use atan2f from CORE-MATH
Adhemerval Zanella: The CORE-MATH implementation is correctly rounded (for any rounding mode) and shows slight better performance to the generic atan2f.

math: Use atanf from CORE-MATH
Adhemerval Zanella: The CORE-MATH implementation is correctly rounded (for any rounding mode) and shows slight better performance to the generic atanf.

math: Use asinhf from CORE-MATH
Adhemerval Zanella: The CORE-MATH implementation is correctly rounded (for any rounding mode) and shows slight better performance to the generic asinhf.

math: Use asinf from CORE-MATH
Adhemerval Zanella: The CORE-MATH implementation is correctly rounded (for any rounding mode) and shows slight better performance to the generic asinf.

math: Use acoshf from CORE-MATH
Adhemerval Zanella: The CORE-MATH implementation is correctly rounded (for any rounding mode) and shows slight better performance to the generic acoshf.

math: Use acosf from CORE-MATH
Adhemerval Zanella: The CORE-MATH implementation is correctly rounded (for any rounding mode) and shows slight better performance to the generic acosf.

math: Fix the expected atan2f (inf) results
Adhemerval Zanella: The pi defined constants are not the expected value for atan2 on non-default rounding modes.

nptl: Add for sparc
Michael Jeanson: This will be required by the rseq extensible ABI implementation on all Linux architectures exposing the '__rseq_size' and '__rseq_offset' symbols to set the initial value of the 'cpu_id' field which can be used by applications to test if rseq is available and registered.

Update syscall lists for Linux 6.12
Joseph Myers: Linux 6.12 has no new syscalls.

ungetc: Guarantee single char pushback
Siddhesh Poyarekar: The C standard requires that ungetc guarantees at least one pushback, but the malloc call to allocate the pushback buffer could fail, thus violating that requirement.

tst-unique3.cc: Add explicit instantiation declaration for S::i
H.J. Lu: Add explicit instantiation declaration of S<char>::i to silence Clang error:

ldbl-96: Set -1 to "int sign_exponent:16"
H.J. Lu: ieee_long_double_shape_type has

Remove left over LD_LIBRARY_VERSION usages
Adhemerval Zanella: The environment variable was removed by d2db60d8d830ef68c8d20a77ac3572d610aa40b1.

linux: Add process_mrelease
Adhemerval Zanella: Added in Linux 5.15 (884a7e5964e06ed93c7771c0d7cf19c09a8946f1), the new syscalls allows a caller to free the memory of a dying target process. Checked on x86_64-linux-gnu.

Remove kernel version check
Adhemerval Zanella: The kernel version check is used to avoid glibc to run on older kernels where some syscall are not available and fallback code are not enabled to handle graciously fail.

Remove nios2-linux-gnu
Adhemerval Zanella: GCC 15 (e876acab6cdd84bb2b32c98fc69fb0ba29c81153) and binutils (e7a16d9fd65098045ef5959bf98d990f12314111) both removed all Nios II support, and the architecture has been EOL'ed by the vendor.

locale: More strictly implement ISO 8601 for Esperanto locale
Carmen Bianca BAKKER: Esperanto, as an international language and a bit of a non-locale, usually defaults to international consensus.
