I'm trying to implement this currently, and have two observations: 1) musl.so seems to have .eh_frame even with default options currently. GCC insists generating it for the PLT. Though otherwise it's empty. This is on gcc 10.3.1. 2) .debug_frame is 109944 bytes, while .eh_frame_hdr + .eh_frame is 83832. The size difference seems to be because of CIE entries not being merged for .debug_frame. Timo
