From 36f779c06332319d9dc2d456e098a99b2540cefc Mon Sep 17 00:00:00 2001 From: Dimitar Dimitrov Date: Fri, 27 May 2022 23:09:24 +0300 Subject: [PATCH] pru: bfd: Correct default to no execstack Data and instruction memories are strictly separated, so it is not possible to execute instructions from the stack memory on PRU. I don't see any difference in testsuite results with or without this change. bfd/ChangeLog: * elf32-pru.c (elf_backend_default_execstack): Define as 0. ld/ChangeLog: * testsuite/ld-elf/elf.exp (target_defaults_to_execstack): Return 0 for pru.
