1997-09-21 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de> * elf/sofini.c [HAVE_DWARF2_UNWIND_INFO]: Supply termination for the frame unwind info section. added /* Terminate the frame unwind info section with a 4byte 0 as a sentinel; this would be the 'length' field in a real FDE. */ typedef unsigned int ui32 __attribute__ ((mode (SI))); static const ui32 __FRAME_END__[1] __attribute__ ((used, section (".eh_frame"))) = { 0 }; to elf/sofini.c. Since libc.so is created with # gcc -shared -static-libgcc ... elf/sofini.os .. -lgcc The zero terminator is placed in the middle of glibc's .eh_frame due to object files included from libgcc.a. Do we still need it today?
This is related to PR 22048.

Since libc.so is always built with --eh-frame-hdr, do we still need ZERO terminator?
Due to float128 we now pull quite some stuff from libgcc.
