2021-12-28elf: Add _dl_find_object functionFlorian Weimer
It can be used to speed up the libgcc unwinder, and the internal _dl_find_dso_for_object function (which is used for caller identification in dlopen and related functions, and in dladdr). _dl_find_object is in the internal namespace due to bug 28503. If libgcc switches to _dl_find_object, this namespace issue will be fixed. It is located in libc for two reasons: it is necessary to forward the call to the static libc after static dlopen, and there is a link ordering issue with -static-libgcc and libgcc_eh.a because libc.so is not a linker script that includes ld.so in the glibc build tree (so that GCC's internal -lc after libgcc_eh.a does not pick up ld.so). It is necessary to do the i386 customization in the sysdeps/x86/bits/dl_find_object.h header shared with x86-64 because otherwise, multilib installations are broken. The implementation uses software transactional memory, as suggested by Torvald Riegel. Two copies of the supporting data structures are used, also achieving full async-signal-safety.

2021-12-28microblaze: Add missing implementation when !__ASSUME_TIME64_SYSCALLSThomas Petazzoni
In commit a92f4e6299fe0e3cb6f77e79de00817aece501ce ("linux: Add time64 pselect support"), a Microblaze specific implementation of __pselect32() was added to cover the case of kernels < 3.15 which lack the pselect6 system call. This new file sysdeps/unix/sysv/linux/microblaze/pselect32.c takes precedence over the default implementation sysdeps/unix/sysv/linux/pselect32.c. However sysdeps/unix/sysv/linux/pselect32.c provides an implementation of __pselect32() which is needed when __ASSUME_TIME64_SYSCALLS is not defined. On Microblaze, which is a 32-bit architecture, __ASSUME_TIME64_SYSCALLS is only true for kernels >= 5.1. Due to sysdeps/unix/sysv/linux/microblaze/pselect32.c taking precedence over sysdeps/unix/sysv/linux/pselect32.c, it means that when we are with a kernel >= 3.15 but < 5.1, we need a __pselect32() implementation, but sysdeps/unix/sysv/linux/microblaze/pselect32.c doesn't provide it, and sysdeps/unix/sysv/linux/pselect32.c which would provide it is not compiled in. This causes the following build failure on Microblaze with for example Linux kernel headers 4.9: [...]/build/libc_pic.os: in function `__pselect64': (.text+0x120b44): undefined reference to `__pselect32' collect2: error: ld returned 1 exit status Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

2021-12-28hurd: Fix static-PIE startupSamuel Thibault
hurd initialization stages use RUN_HOOK to run various initialization functions. That is however using absolute addresses which need to be relocated, which is done later by csu. We can however easily make the linker compute relative addresses which thus don't need a relocation. The new SET_RELHOOK and RUN_RELHOOK macros implement this.
2021-12-28hurd: let csu initialize tlsSamuel Thibault
Since 9cec82de715b ("htl: Initialize later"), we let csu initialize pthreads. We can thus let it initialize tls later too, to better align with the generic order. Initialization however accesses ports which links/unlinks into the sigstate for unwinding. We can however easily skip that during initialization.

2021-12-27x86: Optimize L(less_vec) case in memcmpeq-evex.SNoah Goldstein
No bug. Optimizations are twofold. 1) Replace page cross and 0/1 checks with masked load instructions in L(less_vec). In applications this reduces branch-misses in the hot [0, 32] case. 2) Change controlflow so that L(less_vec) case gets the fall through. Change 2) helps copies in the [0, 32] size range but comes at the cost of copies in the [33, 64] size range. From profiles of GCC and Python3, 94%+ and 99%+ of calls are in the [0, 32] range so this appears to the the right tradeoff. Signed-off-by: Noah Goldstein <goldstein.w.n@gmail.com> Reviewed-by: H.J.

2021-12-17powerpc64[le]: Allocate extra stack frame on syscall.SMatheus Castanho
The syscall function does not allocate the extra stack frame for scv like other assembly syscalls using DO_CALL_SCV. So after commit d120fb9941 changed the offset that is used to save LR, syscall ended up using an invalid offset, causing regressions on powerpc64. So make sure the extra stack frame is allocated in syscall.S as well to make it consistent with other uses of DO_CALL_SCV and avoid similar issues in the future.
