Subject: [GOLD, PowerPC64] Debug info relocation overflow
Date: Wed, 19 Jul 2023 11:12:10 +0930 [thread overview]
Message-ID: <ZLc/ckC/wa90hisa@squeak.grove.modra.org> (raw)
It is possible to build huge binaries on powerpc64, where 32-bit
addresses in debug info are insufficient to descibe locations in the
binary. Help out the user, and only warn about debug overflows.
* powerpc.cc (Target_powerpc::Relocate::relocate): Warn on
relocation overflows in debug info.
