In our custom port, GCC generate debugging symbols that are mis-aligned.
How to make GCC generate debugging symbols that are properly aligned ?

To further clarify on the issue we are having, below is an excerpt
from the output of readelf showing mis-aligned debugging symbols:
Relocation section '.rela.debug_line' at offset 0x1fec contains 19 entries:
Offset Info Type Sym.Value Sym. Name + Addend
000000f7 00000603 R_ARCH_32 00000000 .text.startup + 0
00000101 00000603 R_ARCH_32 00000000 .text.startup + 18
0000010b 00000603 R_ARCH_32 00000000 .text.startup + 30
00000115 00000603 R_ARCH_32 00000000 .text.startup + 64
Any idea how to make GCC generate debugging symbols that are properly aligned ?

This is unaligned by design, to help reduce the size of the debug
info. Debug info isn't performance critical, so dealing with
unaligned data is not a problem here. To fix it, you would have to
use a different debug info format, but there isn't one we support as
well as dwarf2.
