Bug ID: 28601
Summary: gold: Support DT_RELR relative relocation format
Product: binutils
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gold
Assignee: ccoutant at gmail dot com
Reporter: i at maskray dot me
CC: ian at airs dot com
Target Milestone: ---
gold version of https://sourceware.org/bugzilla/show_bug.cgi?id=27923 (GNU ld
support).
I have a patch which will be posted soon.
The patch implements ld.lld flavored --pack-dyn-relocs=relr.
It doesn't do any "time travel compatibility"
(https://maskray.me/blog/2021-10-31-relative-relocations-and-relr#time-travel-compatibility).
Such mechanism is unnecessary for many groups because they do not want to bump
EI_ABIVERSION or synthesize a glibc flavored versioned symbol.
If glibc (actually some distro, not even necessarily the majority) is really
fond of "time-travel-compatibility", perhaps we can add something like
--pack-dyn-relocs=relr-glibc, but I'd be very sad to see a dedicated option
variant is added (for the first time) for one particular libc implementation.
