[LLVM-158] Buildbot monitoring duty - Reported bug that libc++ when built as part as libfuzzer is not built with PIC or PIE, yet some tests for non-x86 force PIE which then fails at link-time. - Reported bugs in libstdc++ and clang where exception specifications didn't match due to extra parentheses. libstdc++ now fixed to not have any discrepancy, clang bug for not ignoring the extra parentheses still active. - Investigated libfuzzer intermittent failures, 2 look like timeouts not being long enough, submitted patch to get this increased. [LLVM-122] BTI/PAC Started prototyping an implementation based on top of the yet to land LLD patch for Intel CET.
Think about how to add crypto extensions without overriding architecture in a complex build system. Review comments for LLD and compiler-rt, and mailing list proposal for something similar to __attribute__((at(address))).
