Backport changed from 2.5: REQUIRED, 2.6: REQUIRED, 2.7: DONE to 2.5: REQUIRED, 2.6: DONE, 2.7: DONE ruby_2_6 r67932 merged revision(s) abe2e7de4d1f2d5861d7c9ab9c7e778f2ee1dcd2. ---------------------------------------- Bug #16774: Don't require sub-word atomics https://bugs.ruby-lang.org/issues/16774#change-91306 * Author: schwab (Andreas Schwab) * Status: Closed * Priority: Normal * Backport: 2.5: REQUIRED, 2.6: DONE, 2.7: DONE ---------------------------------------- On some architectures (like RISC-V) sub-word atomics are only available when linking against -latomic, but the configure script doesn't do that, causing the atomic checks to fail and the resulting ruby binary is non-functional. Ruby does not use sub-word atomic operations, rb_atomic_t is defined to unsigned int, so use unsigned int when checking for atomic operations. ---Files-------------------------------- 0001-Don-t-require-sub-word-atomics.patch (1.41 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
