* or1k: Only define fpu rouding and exceptions with hard-floatStafford Horne2024-03-221-0/+19
| | | | | | | | | | | | | | This test failure: math/test-fenv If rounding mode and exception macros are defined then the fenv tests run and always fail. This patch adds an ifdef using the __or1k_hard_float__ macro provided by gcc to avoid defining these fenv macros when they cnnot be used. This is similar to what is done in csky. Note, I will post the or1k hard-float support soon. So, I prefer to leave the hard-float bits here for now.

* AArch64: Check kernel version for SVE ifuncsWilco Dijkstra2024-03-215-2/+53
| | | | | | | | | | | | | | | | Old Linux kernels disable SVE after every system call. Calling the SVE-optimized memcpy afterwards will then cause a trap to reenable SVE. As a result, applications with a high use of syscalls may run slower with the SVE memcpy. This is true for kernels between 4.15.0 and before 6.2.0, except for 5.14.0 which was patched. Avoid this by checking the kernel version and selecting the SVE ifunc on modern kernels. Parse the kernel version reported by uname() into a 24-bit kernel.major.minor value without calling any library functions. If uname() is not supported or if the version format is not recognized, assume the kernel is modern. Tested-by: Florian Weimer <fweimer@redhat.com> Reviewed-by: Szabolcs Nagy <szabolcs.nagy@arm.com>

In order to get faster access to the HWCAP3/HWCAP4 masks, similar to HWCAP/HWCAP2 (i.e. for implementing __builtin_cpu_supports() in GCC) without the overhead of reading them from the auxiliary vector, we now reserve space for them in the TCB.

* arm: Update _dl_tlsdesc_dynamic to preserve caller-saved registers (BZ 31372)Adhemerval Zanella2024-03-1910-15/+250
| | | | | | | | | | | | | | | | | | | | | | ARM _dl_tlsdesc_dynamic slow path has two issues: * The ip/r12 is defined by AAPCS as a scratch register, and gcc is used to save the stack pointer before on some function calls. So it should also be saved/restored as well. It fixes the tst-gnu2-tls2. * None of the possible VFP registers are saved/restored. ARM has the additional complexity to have different VFP bank sizes (depending of VFP support by the chip). The tst-gnu2-tls2 test is extended to check for VFP registers, although only for hardfp builds. Different than setcontext, _dl_tlsdesc_dynamic does not have HWCAP_ARM_IWMMXT (I don't have a way to properly test it and it is almost a decade since newer hardware was released). With this patch there is no need to mark tst-gnu2-tls2 as XFAIL. Checked on arm-linux-gnueabihf. Reviewed-by: H.J. Lu <hjl.tools@gmail.com>

* linux: Use rseq area unconditionally in sched_getcpu (bug 31479)Florian Weimer2024-03-151-8/+0
| | | | | | | | | | | | | | | | | | | Originally, nptl/descr.h included <sys/rseq.h>, but we removed that in commit 2c6b4b272e6b4d07303af25709051c3e96288f2d ("nptl: Unconditionally use a 32-byte rseq area"). After that, it was not ensured that the RSEQ_SIG macro was defined during sched_getcpu.c compilation that provided a definition. This commit always checks the rseq area for CPU number information before using the other approaches. This adds an unnecessary (but well-predictable) branch on architectures which do not define RSEQ_SIG, but its cost is small compared to the system call. Most architectures that have vDSO acceleration for getcpu also have rseq support.

| | | | | | | | | | | | | Due to GCC bug 110901 -mcpu can override -march setting when compiling asm code and thus a compiler targetting a specific cpu can fail the configure check even when binutils gas supports SVE.

* riscv: Fix alignment-ignorant memcpy implementationAdhemerval Zanella2024-03-129-167/+215
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The memcpy optimization (commit 587a1290a1af7bee6db) has a series of mistakes: - The implementation is wrong: the chunk size calculation is wrong leading to invalid memory access. - It adds ifunc supports as default, so --disable-multi-arch does not work as expected for riscv. - It mixes Linux files (memcpy ifunc selection which requires the vDSO/syscall mechanism) with generic support (the memcpy optimization itself). - There is no __libc_ifunc_impl_list, which makes testing only check the selected implementation instead of all supported by the system. This patch also simplifies the required bits to enable ifunc: there is no need to memcopy.h; nor to add Linux-specific files. The __memcpy_noalignment tail handling now uses a branchless strategy similar to aarch64 (overlap 32-bits copies for sizes 4..7 and byte copies for size 1..3).

* riscv: Enable multi-arg ifunc resolversEvan Green2024-03-012-11/+44
| | | | | | | | | | | | | | | | | | | | | | | | RISC-V is apparently the first architecture to pass more than one argument to ifunc resolvers. The helper macros in libc-symbols.h, __ifunc_resolver(), __ifunc(), and __ifunc_hidden(), are incompatible with this. These macros have an "arg" (non-final) parameter that represents the parameter signature of the ifunc resolver. The result is an inability to pass the required comma through in a single preprocessor argument. Rearrange the __ifunc_resolver() macro to be variadic, and pass the types as those variable parameters. Move the guts of __ifunc() and __ifunc_hidden() into new macros, __ifunc_args(), and __ifunc_args_hidden(), that pass the variable arguments down through to __ifunc_resolver(). Then redefine __ifunc() and __ifunc_hidden(), which are used in a bunch of places, to simply shuffle the arguments down into __ifunc_args[_hidden]. Finally, define a riscv-ifunc.h header, which provides convenience macros to those looking to write ifunc selectors that use both arguments.

* riscv: Add __riscv_hwprobe pointer to ifunc callsEvan Green2024-03-012-4/+15
| | | | | | | | | | | | | | | | | | The new __riscv_hwprobe() function is designed to be used by ifunc selector functions. This presents a challenge for applications and libraries, as ifunc selectors are invoked before all relocations have been performed, so an external call to __riscv_hwprobe() from an ifunc selector won't work. To address this, pass a pointer to the __riscv_hwprobe() function into ifunc selectors as the second argument (alongside dl_hwcap, which was already being passed). Include a typedef as well for convenience, so that ifunc users don't have to go through contortions to call this routine. Users will need to remember to check the second argument for NULL, to account for older glibcs that don't pass the function.
