From 087ea22225435ab5800e6c29671acab40dc6ca82 Mon Sep 17 00:00:00 2001 From: Alan Modra Date: Thu, 18 May 2017 14:28:17 +0930 Subject: [PATCH] pr20882 testcase -gdwarf-sections doesn't work on targets that lack support to emit address size relative relocs. The testcase as it was avoided -gdwarf-sections doing anything by providing a non-empty .debug_line. It's better to not use -gdwarf-sections. Also, the testcase failed to match the output for 16-bit address targets like avr. PR ld/20882 * testsuite/ld-gc/pr20882.d: Don't pass -gdwarf-sections to gas. Allow for 16-bit address targets and match expected data fully. * testsuite/ld-gc/pr20882a.s: Delete .debug_line section. * testsuite/ld-gc/pr20882b.s: Likewise. * testsuite/ld-gc/pr20882c.s: Likewise. --- ld/ChangeLog | 9 +++++++++ ld/testsuite/ld-gc/pr20882.d | 3 +-- ld/testsuite/ld-gc/pr20882a.s | 7 ++----- ld/testsuite/ld-gc/pr20882b.s | 3 --- ld/testsuite/ld-gc/pr20882c.s | 3 --- 5 files changed, 12 insertions(+), 13 deletions(-) diff --git a/ld/ChangeLog b/ld/ChangeLog index b71bc16..c5892d1 100644 --- a/ld/ChangeLog +++ b/ld/ChangeLog @@ -1,3 +1,12 @@ +2017-05-18 Alan Modra + + PR ld/20882 + * testsuite/ld-gc/pr20882.d: Don't pass -gdwarf-sections to gas. + Allow for 16-bit address targets and match expected data fully. + * testsuite/ld-gc/pr20882a.s: Delete .debug_line section. + * testsuite/ld-gc/pr20882b.s: Likewise. + * testsuite/ld-gc/pr20882c.s: Likewise. + 2017-05-17 H.J.
