Bug ID: 33663
Summary: "ld --help" doesn't mention -z pack-relative-relocs
for AArch64 targets
Product: binutils
Version: 2.46 (HEAD)
Status: UNCONFIRMED
Severity: minor
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: Felix.Riemann at sma dot de
Target Milestone: ---
ld's help text (ld --help) doesn't list the "-z pack-relative-relocs" and "-z
no-pack-relative-relocs" parameters to enable DT_RELR on builds targetting
Linux ELF on ARM64.
Although one now might think that they are not supported for this target, they
work fine. Linking a shared object with "-z pack-relative-relocs" enabled has
the expected effect and doesn't warn about ignored parameters.
Steps to Reproduce
* Build an ld targetting AArch64 on Linux, e.g. "./configure
--target=aarch64-linux-gnu"
* Call "ld --help | grep pack-relative-relocs"
Expected Results
The description for the parameters is found at least once:
-z pack-relative-relocs Pack relative relocations
-z nopack-relative-relocs Do not pack relative relocations (default)
Actual Result
grep returns an empty list.
Build Date & Hardware
Reproduces with binutils 2.45 and HEAD (gdb-17-branchpoint-946-g12856136986)
targetting Linux on AArch64. Both builds were hosted on x84_64.
Additional Builds and Platforms
The parameters are listed when trying an ld for x86_64 Linux.
