[Bug ld/22423] PT_PHDR segment is marked with PF_X
https://sourceware.org/bugzilla/show_bug.cgi?id=22423 --- Comment #3 from cvs-commit at gcc dot gnu.org --- The master branch has been updated by H.J. Lu : https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=f882209d9aa5b68d68c45c5849e129ffc228749c commit f882209d9aa5b68d68c45c5849e129ffc228749c Author: H.J. Lu Date: Sun Nov 12 17:03:50 2017 -0800 ld: Remove PF_X from PT_PHDR segment It was reasonable to mark PT_PHDR segment with PF_X for compatibility with UnixWare and Solaris linkers 20 years ago. But it is inappropriate today when the primary OS of GNU ld is Linux. This patch removes PF_X from PT_PHDR segment as gold does. Tested natively on Linux/x86 as well as crosss-binutils for alpha-linux, ia64-linux, powerpc64-linux, powerpc-linux, s390-linux, s390x-linux, sparc64-linux and sparc-linux. bfd/ PR ld/22423 * elf.c (_bfd_elf_map_sections_to_segments): Remove PF_X from PT_PHDR segment. ld/ PR ld/22423 * testsuite/ld-alpha/tlsbin.rd: Replace "R E " with "R +" for PT_PHDR segment. * testsuite/ld-alpha/tlsbinr.rd: Likewise. * testsuite/ld-ia64/tlsbin.rd: Likewise. * testsuite/ld-powerpc/tlsexe.r: Likewise. * testsuite/ld-powerpc/tlsexe32.r: Likewise. * testsuite/ld-powerpc/tlsexetoc.r: Likewise. * testsuite/ld-s390/tlsbin.rd: Likewise. * testsuite/ld-s390/tlsbin_64.rd: Likewise. * testsuite/ld-sparc/tlssunbin32.rd: Likewise. * testsuite/ld-sparc/tlssunbin64.rd: Likewise. * testsuite/ld-elf/pr22423.d: New test. -- You are receiving this mail because: You are on the CC list for the bug. ___ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
