.plt.sec is IIRC the "second" (sec) PLT entry - the one that will be used on the second call (and on). This is used / emitted for ELF object instrumented for Intel CET. The details escape me for the moment but I hope the x86 ABI documents this (and the constraints) in detail.
Btw, I suggest to involve HJL in the discussion on how to fix perf, he might even have fixes for that. -- You are receiving this mail because: You are on the CC list for the bug.
