From 856ea05ccf051d4d86f422552f5cdfa83659dd6b Mon Sep 17 00:00:00 2001 From: Kaushik Phata Date: Fri, 16 May 2014 14:57:10 +0100 Subject: This adds support for marking RL78 binaries as either supporting 32-bit or 64-bit doubles. It also makes the linker complain if the user attempts to link together binaries with different sized doubles. * elf32-rl78.c (rl78_elf_merge_private_bfd_data): Complain if 64-bit doubles objects mix with 32-bit doubles objects. (rl78_elf_print_private_bfd_data): Describe 64-bit doubles flag. * readelf.c (get_machine_flags): Handle RL78 64-bit doubles flag. * config/tc-rl78.c (enum options): Add OPTION_32BIT_DOUBLES and OPTION_64BIT_DOUBLES. (md_longopts): Add -m32bit-doubles and -m64bit-doubles. (md_parse_option): Parse -m32bit-doubles and -m64bit-doubles. (md_show_usage): Show all of the RL78 options. (rl78_float_cons): New static functions. (md_pseudo_table): Update handler for "double". --- bfd/elf32-rl78.c | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) (limited to 'bfd/elf32-rl78.c') diff --git a/bfd/elf32-rl78.c b/bfd/elf32-rl78.c index 7b66971..5e62edd 100644 --- a/bfd/elf32-rl78.c +++ b/bfd/elf32-rl78.c @@ -1049,6 +1049,19 @@ rl78_elf_merge_private_bfd_data (bfd * ibfd, bfd * obfd) (*_bfd_error_handler) (_("- %s is G10, %s is not"), bfd_get_filename (ibfd), bfd_get_filename (obfd)); } + + if (changed_flags & E_FLAG_RL78_64BIT_DOUBLES) + { + (*_bfd_error_handler) + (_("RL78 merge conflict: cannot link 32-bit and 64-bit objects together")); + + if (old_flags & E_FLAG_RL78_64BIT_DOUBLES) + (*_bfd_error_handler) (_("- %s is 64-bit, %s is not"), + bfd_get_filename (obfd), bfd_get_filename (ibfd)); + else + (*_bfd_error_handler) (_("- %s is 64-bit, %s is not"), + bfd_get_filename (ibfd), bfd_get_filename (obfd)); + } } return !error; @@ -1071,6 +1084,9 @@ rl78_elf_print_private_bfd_data (bfd * abfd, void * ptr) if (flags & E_FLAG_RL78_G10) fprintf (file, _(" [G10]")); + if (flags & E_FLAG_RL78_64BIT_DOUBLES) + fprintf (file, _(" [64-bit doubles]")); + fputc ('\n', file); return TRUE; } -- cgit v1.1
