ld: fix PR/32297
When _creating_ SFrame information for the linker created .plt.sec, the
code correctly checks for presence of .plt.sec. When _writing_ the
SFrame section for the corresponding .plt.sec, however, the conditionals
were wrongly checking for splt. This was causing an assertion at link
time.
This issue has been known to affect glibc build with SFrame enabled.
No testcase is added just yet. A later commit ensures correct SFrame
stack trace information is created for .plt.got. A test case (where only
.plt and .plt.got are created) is added then.
PR/32297 sframe: bfd assertion with empty main on IBT enabled system
Committed by Indu Bhagat.
ChangeLog:
PR/32297
* bfd/elfxx-x86.c (_bfd_x86_elf_late_size_sections): Check for
plt_second member not for splt.
