ld testsuite use of notarget Much of the time it is better to use xfail rather than notarget to hide a testsuite failure no one is planning on fixing. 1) When a target is fixed, an inappropriate xfail results in XPASS whereas notarget is silent. Leaving in an inappropriate notarget entry risks the bug reappearing later, silently. 2) Tests might be used as a template for a new test, carrying over notarget and/or xfail. Inappropriate notarget entries are silent. 3) An xfailed test that mysteriously XPASSes might actually indicate a bug. * testsuite/ld-elf/attributes.d: Use xfail rather than notarget. * testsuite/ld-elf/hash.d: Likewise. * testsuite/ld-elf/orphan-10.d: Likewise. * testsuite/ld-elf/overlay.d: Likewise. * testsuite/ld-elf/pr14926.d: Likewise. * testsuite/ld-elf/pr17550d.d: Likewise. * testsuite/ld-elf/pr19539.d: Likewise. * testsuite/ld-elf/pr22319.d: Likewise. * testsuite/ld-misc/defsym1.d: Likewise. * testsuite/ld-pe/pr19803.d: Likewise. * testsuite/ld-scripts/assign-loc.d: Likewise. * testsuite/ld-scripts/defined4.d: Likewise. * testsuite/ld-scripts/empty-address-1.d: Likewise. * testsuite/ld-scripts/empty-address-2a.d: Likewise. * testsuite/ld-scripts/empty-address-2b.d: Likewise. * testsuite/ld-scripts/fill.d: Likewise. * testsuite/ld-scripts/fill16.d: Likewise. * testsuite/ld-scripts/pr14962.d: Likewise. * testsuite/ld-scripts/pr14962-2.d: Likewise. * testsuite/ld-unique/pr21529.d: Likewise. * testsuite/ld-elf/compress1a.d: Likewise, and adjust targets. * testsuite/ld-elf/compressed1a.d: Likewise. * testsuite/ld-elf/compressed1d.d: Likewise. * testsuite/ld-elf/compressed1e.d: Likewise. * testsuite/ld-elf/eh5.d: Likewise. * testsuite/ld-elf/group8a.d: Likewise. * testsuite/ld-elf/linkonce2.d: Likewise. * testsuite/ld-elf/orphan-9.d: Likewise. * testsuite/ld-elf/pr17550a.d: Likewise. * testsuite/ld-elf/pr17550b.d: Likewise. * testsuite/ld-elf/pr17550c.d: Likewise. * testsuite/ld-elf/pr19162.d: Likewise. * testsuite/ld-elf/pr21884.d: Likewise. * testsuite/ld-gc/pr19167.d: Likewise. * testsuite/ld-gc/pr20022.d: Likewise. * testsuite/ld-gc/start.d: Likewise. * testsuite/ld-elf/orphan-11.d: Delete notarget. * testsuite/ld-elf/orphan-12.d: Likewise. * testsuite/ld-gc/stop.d: Likewise. * testsuite/ld-scripts/empty-address-3a.d: Likewise. * testsuite/ld-scripts/empty-address-3b.d: Likewise. * testsuite/ld-ifunc/pr17154-x86-64-now.d: Delete duplicate notarget. * testsuite/ld-scripts/section-match-1.d: Comment fix. 2018-07-10 21:43:10 +08:00			`#xfail: dlx--`
