[compiler-rt][asan] Re-enable ManyThreadsTest on AArch64

c-rhodes · c-rhodes · commit 4945212b1575 · 2025-02-19T13:43:21.000Z
Disabled in 2ab51bf, doesn't hang for me on AArch64 (Graviton 3, tested 1000 iterations). May still be an issue, but hard to know unless we enable it again to find out. n.b. test was also disabled on PowerPC in 467afc5 for same reason and it has also been observed on x86: https://lists.llvm.org/pipermail/llvm-dev/2016-January/094607.html Fixes: #24763
