Speaking of optimization, I think the rseq.c helper library
(and eventually glibc) should define the __rseq_abi TLS
variable with __attribute__((tls_model("initial-exec"))).
It provides faster, and signal-safe, accesses to the TLS
variable from libraries.The idea you were suggesting where the application could override the glibc symbol with its own just ends up enforcing an initial-exec model, but it looks like we can do this directly from the library. Thoughts ? Thanks, Mathieu -- Mathieu Desnoyers EfficiOS Inc. http://www.efficios.com
