Alan Modra	c40e31a121	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.
