Returns a buffer containing a description of the E_FLAG_RX_... values set. (rx_elf_merge_private_bfd_data): Use it. (rx_elf_print_private_bfd_data): Likewise. (elf32_rx_machine): Skip EF_RX_CPU_RX check. (elf32_rx_special_sections): Define. (elf_backend_special_sections): Define. 2012-11-09 Nick Clifton * readelf.c (get_machine_flags): Add support for E_FLAG_RX_ABI. 2012-11-09 Nick Clifton * config/obj-elf.c (obj_elf_change_section): Allow init array sections to have the SHF_EXECINSTR attribute for the RX target. * config/tc-rx.c (elf_flags): Initialise with E_FLAG_RX_ABI. (enum options): Add OPTION_USES_GCC_ABI and OPTION_USES_RX_ABI. (md_longopts): Add -mgcc-abi and -mrx-abi. (md_parse_option): Add support for OPTION_USES_GCC_ABI and OPTION_USES_RX_ABI. * doc/as.texinfo (RX Options): Add mention of remaining RX options. * doc/c-rx.texi: Document -mgcc-abi and -mrx-abi. 2012-11-09 Nick Clifton * rx.h (EF_RX_CPU_RX): Add comment. (E_FLAG_RX_ABI): Define. 2012-11-09 Nick Clifton * emultempl/rxelf.em (no_flag_mismatch_warnings): Initialise to true. (PARSE_AND_LIST_LONGOPTS): Add flag-mismatch-warnings. (PARSE_AND_LIST_ARG_CASES): Add support for --flag-mismatch-warnings. --- gas/config/obj-elf.c | 8 ++++++++ gas/config/tc-rx.c | 14 +++++++++++++- 2 files changed, 21 insertions(+), 1 deletion(-) (limited to 'gas/config') diff --git a/gas/config/obj-elf.c b/gas/config/obj-elf.c index d7c7665..d0fbcfb 100644 --- a/gas/config/obj-elf.c +++ b/gas/config/obj-elf.c @@ -658,6 +658,14 @@ obj_elf_change_section (const char *name, else if ((attr & ~ssect->attr) == SHF_ALPHA_GPREL) override = TRUE; #endif +#ifdef TC_RX + else if (attr == (SHF_EXECINSTR | SHF_WRITE | SHF_ALLOC) + && (ssect->type == SHT_INIT_ARRAY + || ssect->type == SHT_FINI_ARRAY + || ssect->type == SHT_PREINIT_ARRAY)) + /* RX init/fini arrays can and should have the "awx" attributes set. */ + ; +#endif else { if (group_name == NULL) diff --git a/gas/config/tc-rx.c b/gas/config/tc-rx.c index 3db8fe1..b1d0b20 100644 --- a/gas/config/tc-rx.c +++ b/gas/config/tc-rx.c @@ -46,7 +46,7 @@ const char EXP_CHARS[] = "eE"; const char FLT_CHARS[] = "dD"; /* ELF flags to set in the output file header. */ -static int elf_flags = 0; +static int elf_flags = E_FLAG_RX_ABI; bfd_boolean rx_use_conventional_section_names = FALSE; static bfd_boolean rx_use_small_data_limit = FALSE; @@ -70,6 +70,8 @@ enum options OPTION_RELAX, OPTION_PID, OPTION_INT_REGS, + OPTION_USES_GCC_ABI, + OPTION_USES_RX_ABI, }; #define RX_SHORTOPTS "" @@ -94,6 +96,8 @@ struct option md_longopts[] = {"relax", no_argument, NULL, OPTION_RELAX}, {"mpid", no_argument, NULL, OPTION_PID}, {"mint-register", required_argument, NULL, OPTION_INT_REGS}, + {"mgcc-abi", no_argument, NULL, OPTION_USES_GCC_ABI}, + {"mrx-abi", no_argument, NULL, OPTION_USES_RX_ABI}, {NULL, no_argument, NULL, 0} }; size_t md_longopts_size = sizeof (md_longopts); @@ -143,6 +147,14 @@ md_parse_option (int c ATTRIBUTE_UNUSED, char * arg ATTRIBUTE_UNUSED) case OPTION_INT_REGS: rx_num_int_regs = atoi (optarg); return 1; + + case OPTION_USES_GCC_ABI: + elf_flags &= ~ E_FLAG_RX_ABI; + return 1; + + case OPTION_USES_RX_ABI: + elf_flags |= E_FLAG_RX_ABI; + return 1; } return 0; } -- cgit v1.1
