Wayne Thornton commented on a discussion on cpukit/include/rtems/dhrl.h: https://gitlab.rtems.org/rtems/rtos/rtems/-/merge_requests/1193#note_150605 > +/* SPDX-License-Identifier: BSD-2-Clause */ > + > +/** > + * @file > + * > + * @brief Deterministic Hedged Read Library (DHRL) Public API > + * > + * @note This library is explicitly constrained to x86_64/amd64 > architectures. @gedare That makes perfect sense. I agree that failing loudly at compile-time is much safer than allowing silent fallbacks on unsupported hardware. I removed the empty assembly fallback in dhrl.c and replaced it with an #error directive. If _CPU_Pause_speculation is missing, the build will now explicitly halt. The spec/build/cpukit/libdhrl.yml specification to include enabled-by: RTEMS_SMP was already included and the build system was already entirely skipping the library on uni-processor targets. -- View it on GitLab: https://gitlab.rtems.org/rtems/rtos/rtems/-/merge_requests/1193#note_150605 You're receiving this email because of your account on gitlab.rtems.org.
