--- Comment #2 from cvs-commit at gcc dot gnu.org <cvs-commit at gcc dot gnu.org> --- The binutils-2_30-branch branch has been updated by H.J. Lu <h...@sourceware.org>: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=963e88c631ad5878d70d055fd8597c83279efe66 commit 963e88c631ad5878d70d055fd8597c83279efe66 Author: H.J. Lu <hjl.to...@gmail.com> Date: Mon Mar 26 03:57:01 2018 -0700 x86-64: Add ENDBR64 to the TLSDESC PLT entry The TLSDESC entry in a lazy procedure linkage table is called indirectly with "callq *(%rax)". This patch adds an ENDBR64 to support indirect branch tracking in Intel CET. The TLSDESC PLT entry now looks like: 0xf3, 0x0f, 0x1e, 0xfa, /* endbr64 */ 0xff, 0x35, 8, 0, 0, 0, /* pushq GOT+8(%rip) */ 0xff, 0x25, 16, 0, 0, 0 /* jmpq *GOT+TDG(%rip) */ The BND prefix isn't needed since MPX isn't used for TLSDESC. bfd/ PR ld/23000 * elf64-x86-64.c (elf_x86_64_finish_dynamic_sections): Add ENDBR64 to the TLSDESC PLT entry. ld/ PR ld/23000 * testsuite/ld-x86-64/tlsdesc.pd: Updated.
