Reproducer for failure to incrementally link an executable with LTO
Hi,
Commit 5c3261b0e834647cf9eb555320e20871b7854f98 in binutils broke the ability
to redefine a weak function in an LTO incrementally-linked executable.
Reproducer is attached to this bug report.
Running ./reproducer.sh shows the following error:
test-intermediate: In function `main':
/home/thopre01/issues/sjp/weak_lto_incremental_link/test-weak.c:8: undefined
reference to `foobar'
collect2: error: ld returned 1 exit status
Best regards,
Thomas
