MicroBlaze had clock_* functions exported from librt in glibc 2.18 and 2.19, as confirmed in <https://sourceware.org/ml/libc-alpha/2017-01/msg00369.html>, and they then disappeared in 2.20, presumably as a result of the fix <https://sourceware.org/ml/libc-alpha/2014-02/msg00598.html> for a Versions.def bug that had resulted in their unintended inclusion in 2.18 (followed by removal of the Versions.def mechanism that allowed such bugs). As they were released in that library, they should be considered part of the GLIBC_2.18 ABI and so restored for the sake of any binaries that expect them in that library. This patch restores them by adding a MicroBlaze version of clock-compat.c that overrides SHLIB_COMPAT. Tested (compilation only) with build-many-glibcs.py (where this fixes the librt ABI test failure; elf/check-execstack still fails and still needs architecture maintainer attention to fix it or XFAIL it with an appropriate explanatory comment). [BZ #21061] * sysdeps/unix/sysv/linux/microblaze/clock-compat.c: New file. |
