The [test/hotspot/jtreg/runtime/jni/critical/libSuspendInCritical.cpp](https://github.com/openjdk/jdk/pull/30936/changes#diff-137899820d5ad5d36c91c879aa09a9678112d4be6718ba8e64ebfe1a20f6dda3) library operates with `jlong` native_counter. 32-bit ARM lacks native 8-byte atomic instructions, so GCC emits calls to __atomic_load_8/__atomic_fetch_add_8 from libatomic, which is not linked, causing a build failure.
The issue is fixed by adding -latomic link flag for the library into JtregNativeHotspot.gmk. --------- - [x] I confirm that I make this contribution in accordance with the [OpenJDK Interim AI Policy](https://openjdk.org/legal/ai). ------------- Commit messages: - 8386107: arm32: libSuspendInCritical jtreg library fails to link Changes: https://git.openjdk.org/jdk/pull/31411/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=31411&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8386107 Stats: 3 lines in 1 file changed: 3 ins; 0 del; 0 mod Patch: https://git.openjdk.org/jdk/pull/31411.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/31411/head:pull/31411 PR: https://git.openjdk.org/jdk/pull/31411
