Bug ID: 30091
Summary: Bundle all artifacts and command line invocation to
quickly reproduce linker errors
Product: binutils
Version: unspecified
Status: UNCONFIRMED
Severity: enhancement
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: hiraditya at msn dot com
Target Milestone: ---
The lld linker has a flag `--reproduce -= path` that bundles all the artifacts
along with a `response.txt` file containing command line parameters to be
passed to the linker. This helps quickly debug errors.
As per the doc:
Write a tar file to path, containing all the input files needed to reproduce
the link, a text file called response.txt containing the command line options
and a text file called version.txt containing the output of ld.lld --version.
The archive when unpacked can be used to re-run the linker with the same
options and input files.
