Subject: [PATCH] ld: Replace "{dummy.s}" with "[list $dummy_s]"
commit d658ddcc389085970ac025414cae7ad908f40726
Author: H.J. Lu <hjl.tools@gmail.com>

lto: Don't check format of IR dummy file
added
.section .note.GNU-stack,"",%progbits
to testsuite/ld-plugin/dummy.s for PR ld/34572 tests with Clang. But
it doesn't work for non-ELF targets. Add dummy-elf.s and restore the
previous dummy.s. Define dummy_s to dummy-elf.s for ELF targets and to
dummy.s for non-ELF targets. Replace "{dummy.s}" with "[list $dummy_s]".
Also build pr28264.so only for ELF targets since it uses readelf.
PR ld/28264
PR ld/34572
* testsuite/ld-plugin/dummy-elf.s: New file.
* testsuite/ld-plugin/dummy.s: Revert commit d658ddcc389.
* testsuite/ld-plugin/lto.exp (dummy_s): New.
Build pr28264.so only for ELF targets.
Replace "{dummy.s}" with "[list $dummy_s]".
