Unfortunately there is 14# no symmetrical mcore opcode that functions as a noop. The 15# chosen solution is to use "tst r0, r14". This is a symetrical 16# value, and apart from the corruption of the C bit, it has no other 17# side effects. Since the carry bit is never tested without being 18# explicitly set first, and since the NOP code is only used as a 19# fill value between independantly viable peices of code, it should 20# not matter. 21NOP=0x0e0e0e0e 22 23OTHER_BSS_SYMBOLS="${CREATE_SHLIB+PROVIDE (}__bss_start__ = .${CREATE_SHLIB+)};" 24OTHER_BSS_END_SYMBOLS="${CREATE_SHLIB+PROVIDE (}__bss_end__ = .${CREATE_SHLIB+)};" 25 26# This sets the stack to the top of the simulator memory (2^19 bytes). 27STACK_ADDR=0x80000 28 29TEMPLATE_NAME=elf 30 31# This code gets inserted into the generic elf32.sc linker script 32# and allows us to define our own command line switches. 33PARSE_AND_LIST_PROLOGUE=' 34#define OPTION_BASE_FILE 300 35' 36 37PARSE_AND_LIST_LONGOPTS=' 38 {"base-file", required_argument, NULL, OPTION_BASE_FILE}, 39' 40 41PARSE_AND_LIST_OPTIONS=' 42 fprintf (file, _(" --base_file <basefile> Generate a base file for relocatable DLLs\n")); 43' 44 45PARSE_AND_LIST_ARGS_CASES=' 46 case OPTION_BASE_FILE: 47 link_info.base_file = fopen (optarg, FOPEN_WB); 48 if (link_info.base_file == NULL) 49 einfo (_("%F%P: cannot open base file %s\n"), optarg); 50 break; 51' 52
