2008-07-24 Bean <bean123ch@gmail.com> * common.rmk (bin_UTILITIES): Add grub-pe2elf. (grub_pe2elf_SOURCES): New macro. (CLEANFILES): Add grub-pe2elf. * include/grub/efi/pe32.h (GRUB_PE32_SCN_ALIGN_1BYTES): New constant. (GRUB_PE32_SCN_ALIGN_2BYTES): Likewise. (GRUB_PE32_SCN_ALIGN_4BYTES): Likewise. (GRUB_PE32_SCN_ALIGN_8BYTES): Likewise. (GRUB_PE32_SCN_ALIGN_16BYTES): Likewise. (GRUB_PE32_SCN_ALIGN_32BYTES): Likewise. (GRUB_PE32_SCN_ALIGN_64BYTES): Likewise. (GRUB_PE32_SCN_ALIGN_SHIFT): Likewise. (GRUB_PE32_SCN_ALIGN_MASK): Likewise. (GRUB_PE32_SYM_CLASS_EXTERNAL): Likewise. (GRUB_PE32_SYM_CLASS_STATIC): Likewise. (GRUB_PE32_SYM_CLASS_FILE): Likewise. (GRUB_PE32_DT_FUNCTION): Likewise. (GRUB_PE32_REL_I386_DIR32): Likewise. (GRUB_PE32_REL_I386_REL32): Likewise. (grub_pe32_symbol): New structure. (grub_pe32_reloc): Likewise. * util/grub-pe2elf.c: New file. * configure.ac: Set TARGET_OBJ2ELF if host os is cygwin. Don't test for start symbol in non pc platform. * genmk.rb: Use TARGET_OBJ2ELF to convert native object format to elf. The following patches are from Christian Franke. * include/grub/dl.h: Remove .previous, gas supports this only for ELF format. * include/grub/symbol.h [__CYGWIN__] (#define FUNCTION/VARIABLE): Remove .type, gas supports this only for ELF format. * kern/dl.c (grub_dl_resolve_dependencies): Add check for trailing nullbytes in symbol table. This fixes an infinite loop if table is zero filled. * Makefile.in: Add autoconf replacements TARGET_IMG_LDSCRIPT, TARGET_IMG_LDFLAGS and EXEEXT. * aclocal.m4 (grub_PROG_OBJCOPY_ABSOLUTE): Replace -Wl,-N by TARGET_IMG_LDFLAGS_AC. (grub_CHECK_STACK_ARG_PROBE): New function. * conf/i386-pc.rmk: Replace -Wl,-N by TARGET_IMG_LDFLAGS. * conf/i386-pc-cygwin-ld-img.sc: New linker script. * configure.ac: Add check for linker script "conf/${target}-img-ld.c" to set TARGET_IMG_LD* accordingly. Add check for Cygwin to set TARGET_MOD_OBJCOPY accordingly. Add call to grub_CHECK_STACK_ARG_PROBE. Use TARGET_IMG_LDFLAGS to check start, bss_start, end symbols. * genkernsyms.sh.in: Handle HAVE_ASM_USCORE case. * genmk.rb: Add EXEEXT to CLEANFILES.
