Automatic makefile dependencies for generated ld/e*.c
This patch modifies genscripts.sh to emit dependency info along with the generated emulation e*.c files. This is done by a new source_sh function that records its arg to a file (.deps/e*.Tc), using the function whenever a shell script is sourced. Entries in the file are made unique and written to .deps/e*.Pc. These files are then included by the Makefile. * Makefile.am (GENSCRIPTS): Pass LIB_PATH as a parameter. Add DEPDIR parameter. (ELF_DEPS, ELF_GEN_DEPS, ELF_X86_DEPS): Delete. (ALL_EMULATION_SOURCES, ALL_64_EMULATION_SOURCES): Depend on $GEN_DEPENDS. (e*.c): Delete all dependencies, instead include dependencies from $DEPDIR/*.Pc. * Makefile.in: Regenerate. * configure.ac (source_sh): Define and use function. * configure: Regenerate. * emulparams/aarch64cloudabib.sh, * emulparams/aarch64elf32b.sh, * emulparams/aarch64elfb.sh, * emulparams/aarch64fbsdb.sh, * emulparams/aarch64linux32b.sh, * emulparams/aarch64linuxb.sh, * emulparams/arcelf.sh, * emulparams/arcelf_prof.sh, * emulparams/arclinux.sh, * emulparams/arclinux_nps.sh, * emulparams/arclinux_prof.sh, * emulparams/arcv2elf.sh, * emulparams/arcv2elfx.sh, * emulparams/armelf_fbsd.sh, * emulparams/armelf_linux_eabi.sh, * emulparams/armelf_linux_fdpiceabi.sh, * emulparams/armelf_nacl.sh, * emulparams/armelf_nbsd.sh, * emulparams/armelf_vxworks.sh, * emulparams/armelfb.sh, * emulparams/armelfb_fbsd.sh, * emulparams/armelfb_fuchsia.sh, * emulparams/armelfb_linux.sh, * emulparams/armelfb_linux_eabi.sh, * emulparams/armelfb_linux_fdpiceabi.sh, * emulparams/armelfb_nacl.sh, * emulparams/armelfb_nbsd.sh, * emulparams/armsymbian.sh, * emulparams/cskyelf_linux.sh, * emulparams/elf32_sparc_sol2.sh, * emulparams/elf32_sparc_vxworks.sh, * emulparams/elf32_tic6x_be.sh, * emulparams/elf32_tic6x_elf_be.sh, * emulparams/elf32_tic6x_elf_le.sh, * emulparams/elf32_tic6x_linux_be.sh, * emulparams/elf32_tic6x_linux_le.sh, * emulparams/elf32_x86_64.sh, * emulparams/elf32_x86_64_nacl.sh, * emulparams/elf32b4300.sh, * emulparams/elf32bfinfd.sh, * emulparams/elf32bmipn32.sh, * emulparams/elf32bsmip.sh, * emulparams/elf32btsmip.sh, * emulparams/elf32btsmip_fbsd.sh, * emulparams/elf32btsmipn32.sh, * emulparams/elf32btsmipn32_fbsd.sh, * emulparams/elf32ebmip.sh, * emulparams/elf32ebmipvxworks.sh, * emulparams/elf32elmip.sh, * emulparams/elf32elmipvxworks.sh, * emulparams/elf32frvfd.sh, * emulparams/elf32l4300.sh, * emulparams/elf32lm32fd.sh, * emulparams/elf32lmip.sh, * emulparams/elf32lppc.sh, * emulparams/elf32lppclinux.sh, * emulparams/elf32lppcnto.sh, * emulparams/elf32lppcsim.sh, * emulparams/elf32lr5900.sh, * emulparams/elf32lr5900n32.sh, * emulparams/elf32lriscv.sh, * emulparams/elf32lriscv_ilp32.sh, * emulparams/elf32lriscv_ilp32f.sh, * emulparams/elf32lsmip.sh, * emulparams/elf32ltsmip.sh, * emulparams/elf32ltsmip_fbsd.sh, * emulparams/elf32ltsmipn32.sh, * emulparams/elf32ltsmipn32_fbsd.sh, * emulparams/elf32microblazeel.sh, * emulparams/elf32or1k_linux.sh, * emulparams/elf32ppc.sh, * emulparams/elf32ppc_fbsd.sh, * emulparams/elf32ppccommon.sh, * emulparams/elf32ppclinux.sh, * emulparams/elf32ppcnto.sh, * emulparams/elf32ppcsim.sh, * emulparams/elf32ppcvxworks.sh, * emulparams/elf32ppcwindiss.sh, * emulparams/elf32tilegx_be.sh, * emulparams/elf64_ia64_fbsd.sh, * emulparams/elf64_sparc_fbsd.sh, * emulparams/elf64_sparc_sol2.sh, * emulparams/elf64alpha_fbsd.sh, * emulparams/elf64alpha_nbsd.sh, * emulparams/elf64bmip-defs.sh, * emulparams/elf64bmip.sh, * emulparams/elf64btsmip.sh, * emulparams/elf64btsmip_fbsd.sh, * emulparams/elf64lppc.sh, * emulparams/elf64lriscv-defs.sh, * emulparams/elf64lriscv.sh, * emulparams/elf64lriscv_lp64.sh, * emulparams/elf64lriscv_lp64f.sh, * emulparams/elf64ltsmip.sh, * emulparams/elf64ltsmip_fbsd.sh, * emulparams/elf64ppc.sh, * emulparams/elf64ppc_fbsd.sh, * emulparams/elf64rdos.sh, * emulparams/elf64tilegx_be.sh, * emulparams/elf_i386.sh, * emulparams/elf_i386_be.sh, * emulparams/elf_i386_fbsd.sh, * emulparams/elf_i386_ldso.sh, * emulparams/elf_i386_nacl.sh, * emulparams/elf_i386_sol2.sh, * emulparams/elf_i386_vxworks.sh, * emulparams/elf_iamcu.sh, * emulparams/elf_k1om.sh, * emulparams/elf_k1om_fbsd.sh, * emulparams/elf_l1om.sh, * emulparams/elf_l1om_fbsd.sh, * emulparams/elf_x86_64.sh, * emulparams/elf_x86_64_cloudabi.sh, * emulparams/elf_x86_64_fbsd.sh, * emulparams/elf_x86_64_nacl.sh, * emulparams/elf_x86_64_sol2.sh, * emulparams/h8300helf.sh, * emulparams/h8300helf_linux.sh, * emulparams/h8300hnelf.sh, * emulparams/h8300self.sh, * emulparams/h8300self_linux.sh, * emulparams/h8300snelf.sh, * emulparams/h8300sxelf.sh, * emulparams/h8300sxelf_linux.sh, * emulparams/h8300sxnelf.sh, * emulparams/hppanbsd.sh, * emulparams/hppaobsd.sh, * emulparams/m32rlelf.sh, * emulparams/m32rlelf_linux.sh, * emulparams/m68kelfnbsd.sh, * emulparams/mn10300.sh, * emulparams/msp430X.sh, * emulparams/nds32belf.sh, * emulparams/nds32belf16m.sh, * emulparams/nds32belf_linux.sh, * emulparams/pjlelf.sh, * emulparams/ppclynx.sh, * emulparams/score7_elf.sh, * emulparams/shelf_fd.sh, * emulparams/shelf_linux.sh, * emulparams/shelf_nbsd.sh, * emulparams/shelf_uclinux.sh, * emulparams/shelf_vxworks.sh, * emulparams/shl.sh, * emulparams/shlelf.sh, * emulparams/shlelf_fd.sh, * emulparams/shlelf_nbsd.sh, * emulparams/shlelf_vxworks.sh: Use source_sh. * genscripts.sh: Adjust for changed parameters.

ELF: Call check_relocs after opening all inputs
For all ELF targers, call check_relocs after opening all inputs and
garbage collection. Since the symbol resolution is known, check_relocs
can be simplified. Also garbage collection doesn't need to undo what
check_relocs has done for symbols which have been garbage collected.
Since ELF targets never see the removed sections, gc_sweep_hook can be
removed from elf_backend_data and we can avoid GOT/PLT with garbage
collection now.
Set link_info.check_relocs_after_open_input to TRUE for all linker
targets which use ELF linker and update garbage collection tests to
remove unused GOT section.
ldemul_after_check_relocs is added for powerpc to support --secure-plt,
--bss-plt and --sdata-got.
Tested natively without regressions on i686, x86-64 and x32. Tested
cross binutils on x86-64 without regressions for aarch64-linux,

[x86] Resolve non-PIC undefweak symbols in executable
For i386 and x86-64, non-PIC references to undefined weak symbols are resolved without dynamic relocation when creating executable. Resolved undefined weak symbols are removed from the dynamic symbol table in executable. One exception is on i386, we need resolved undefined weak symbols in the dynamic symbol table in PIE if input relocatable files contain branchs without PLT so that we can branch to 0 with dynamic relocation in text section. This makes behaviors of dynamic executable and position independent executable predictable with mixed PIC and non-PIC references to undefined weak symbols. If all references to undefined weak symbols are PIC, dynamic relocations against undefined weak symbols will be generated in executable unless -z nodynamic-undefined-weak is passed to linker. bfd/ PR ld/19636 PR ld/19704 PR ld/19719 * elf32-i386.c (UNDEFINED_WEAK_RESOLVED_TO_ZERO): New.

Add "-z call-nop=PADDING" option to ld
The ld linker can transform indirect call to a locally defined function,
foo, via its GOT slot, to either "NOP call foo" or "call foo NOP" where
NOP is a 1-byte NOP padding. This patch adds a "-z call-nop=PADDING"
option to x86 ld to control 1-byte NOP padding for x86 call instruction.
PADDING is one of prefix-addr, prefix-nop, suffix-nop, prefix-NUMBER or
suffix-NUMBER.

Add -z noextern-protected-data to ld for ELF/x86
Address of protected data defined in the shared library may be external, i.e., due to copy relocation. By default, linker backend checks if relocations against protected data symbols are valid for building shared library and issues an error if relocation isn't allowed. The new option override linker backend default. When -z noextern-protected-data is used, updates on protected data symbols by another module won't be visibile to the resulting shared library. This option is specific to ELF/i386 and ELF/x86-64. bfd/ PR ld/pr17709 * elflink.c (_bfd_elf_adjust_dynamic_copy): Check info->extern_protected_data when warning copy relocs against protected symbols.
