Unfortunately there is 15# no symmetrical mcore opcode that functions as a noop. The 16# chosen solution is to use "tst r0, r14". This is a symetrical 17# value, and apart from the corruption of the C bit, it has no other 18# side effects. Since the carry bit is never tested without being 19# explicitly set first, and since the NOP code is only used as a 20# fill value between independantly viable peices of code, it should 21# not matter. 22NOP=0x0e0e0e0e 23 24OTHER_BSS_SYMBOLS="${CREATE_SHLIB+PROVIDE (}__bss_start__ = .${CREATE_SHLIB+)};" 25OTHER_BSS_END_SYMBOLS="${CREATE_SHLIB+PROVIDE (}__bss_end__ = .${CREATE_SHLIB+)};" 26 27# This sets the stack to the top of the simulator memory (2^19 bytes). 28STACK_ADDR=0x80000 29 30TEMPLATE_NAME=elf32 31 32# This code gets inserted into the generic elf32.sc linker script 33# and allows us to define our own command line switches. 34PARSE_AND_LIST_PROLOGUE=' 35#define OPTION_BASE_FILE 300 36' 37 38PARSE_AND_LIST_LONGOPTS=' 39 {"base-file", required_argument, NULL, OPTION_BASE_FILE}, 40' 41 42PARSE_AND_LIST_OPTIONS=' 43 fprintf (file, _(" --base_file <basefile> Generate a base file for relocatable DLLs\n")); 44' 45 46PARSE_AND_LIST_ARGS_CASES=' 47 case OPTION_BASE_FILE: 48 link_info.base_file = fopen (optarg, FOPEN_WB); 49 if (link_info.base_file == NULL) 50 einfo (_("%F%P: cannot open base file %s\n"), optarg); 51 break; 52' 53
