Rozycki" Date: Tue, 18 Jul 2017 17:20:30 +0100 Subject: [PATCH] LD/testsuite: Conditionalize the placement of `.dynamic' in GNU_RELRO Complement commit d345186d0535 ("Check if GNU_RELRO segment is is generated") and exclude the presence of a `.dynamic' section from implying the creation of a GNU_RELRO segment for targets which place the section in the (read-only) text segment, and therefore cannot have the section assigned to GNU_RELRO and neither it would make sense. Currently the list of such targets consists of 64-bit HPPA and non-VxWorks MIPS targets, as determined by looking for TEXT_DYNAMIC being set across ld/emulparams/* and then verified by examining default linker scripts produced in a `--enable-targets=all' build. ld/ * testsuite/ld-elf/binutils.exp (binutils_test): Make the expectation for `.dynamic' in GNU_RELRO segment target-specific. --- ld/ChangeLog | 5 +++++ ld/testsuite/ld-elf/binutils.exp | 7 ++++++- 2 files changed, 11 insertions(+), 1 deletion(-) diff --git a/ld/ChangeLog b/ld/ChangeLog index 23babe3f66..7af1ddc060 100644 --- a/ld/ChangeLog +++ b/ld/ChangeLog @@ -1,3 +1,8 @@ +2017-07-18 Maciej W.
