New field 206: arg_words tracks number of words consumed so far and arg_number just 207: tracks physical numbers of arguments. Make four single precision 208: floating point arguments passed via prototypes use $f12, $f14, $6, 209: and $7, just like mips cc. 210: 211: * tm-mips.h (INIT_CUMULATIVE_ARGS, FUNCTION_ARG_ADVANCE, 212: FUNCTION_ARG, FUNCTION_ARG_PARTIAL_NREGS): Type CUMULATIVE_ARGS is 213: now a pointer to a structure instead of a structure, and storage is 214: allocated via alloca. 215: 216: Thu Nov 29 22:03:57 1990 Richard Stallman (rms at mole.ai.mit.edu) 217: 218: * tm-vax.h (BLOCK_PROFILER, FUNCTION_BLOCK_PROFILER): New macros. 219: 220: Tue Nov 27 12:03:36 1990 Richard Stallman (rms at mole.ai.mit.edu) 221: 222: * tm-hp9k320.h (STANDARD_STARTFILE_PREFIX): Don't alter if already set. 223: 224: Tue Nov 27 12:28:45 1990 Michael Meissner (meissner at osf.org) 225: 226: * out-mips.c (function_arg, function_arg_advance): Pass single 227: precision floating point numbers to prototyped functions by assuming 228: only one word is passed rather than two unless the argument is 229: passed in a floating point register. This behavior matches the MIPS 230: C compiler. 231: 232: * tm-mips.h (CPP_SPEC): Add -D_MIPSEB -D_SYSTYPE_SYSV -D_LANGUAGE_C 233: to SGI's CPP_SPEC. 234: (MIPS_DEBUGGING_INFO): New macro. 235: (PUT_SDB_*): Write debug information to the temporary file that 236: buffers the text section, instead of using the current output file. 237: 238: * tm-iris.h (CPP_PREDEFINES): Move -D_LANGUAGE_C from CPP_PREDEFINES 239: to CPP_SPEC since it's in the compiler name space, -ansi should not 240: disable it. 241: 242: Mon Nov 26 18:37:39 1990 Michael Meissner (meissner at osf.org) 243: 244: * mips.md (stack compressor peephole): Remove check against 245: stack_args_preallocated, since nobody sets it. 246: (anonymous add/subtract patterns): Explicitly use the assembler 247: temporary register if adding/subtracting a constant that won't fit 248: in 16 bits -- Silicon Graphics asm complains. 249: (fix_truncdfsi2, fix_truncsfsi2) Rewrite so that optimization of 250: repeated conversions of the same number do not generate an insn not 251: found error message (the generated insn was optimized to a gp->gp 252: register move inside of a parallel with a clobber of a hard fp 253: register). The new insns describe the machine more faithfully, and 254: allow things like clobbering the fp register containing the value, 255: if it is the last use rather than using a specific hard register. 256: (fixuns_truncsfsi2, fixuns_truncdfsi2): New patterns to 257: automatically convert {single,double} precision to unsigned. 258: (anonymous move df/sf patterns): Put the operands to mfc1 in the 259: order the assembler likes them (always put gp reg first, even if 260: moving from gp register to fp register). 261: (wild_insn): Remove bogus insn which is commented out. 262: (jump): Remove TARGET_PIC code for now. 263: 264: * out-mips.c (toplevel, function_epilogue, mips_asm_file_end, 265: mips_output_external): If optimizing for the global pointer, emit 266: all code after processing the entire program, rather than emitting 267: the code at the end of the function. Also, properly sized .extern's 268: are emitted for variables that are not defined in the current 269: module. This is because the MIPS assembler uses single pass 270: semantics, and will emit a 2 instruction sequence for externals it 271: doesn't know anything about, and GCC emits data definitions at the 272: end of the program. You can't just emit a properly sized .extern 273: either, because the assembler will complain if it sees an .extern 274: followed by a definition. The ADDRESSABLE bit in the identifier 275: node for the external name is used to indicate whether a definition 276: for the name exists or not. This replaces code which told the 277: assembler to preprocess the source, and include the same source 278: twice. 279: (sym_lineno): Add a new variable to keep trace of labels emitted 280: after each .loc for Silicon Graphics. 281: (function_prologue, function_epilogue, toplevel): Explicitly use 282: temporary registers for stack frames > 32K, since the Silicon 283: Graphics system doesn't automatically use $at if the value overflows, 284: also save an instruction or two for large stack frames. 285: (init_cumulative_args): Fix to work with the method types G++ 286: produces as well as normal function types. 287: (compare_collect): In debug code, print the mode symbolically. 288: (trace): Take two additional arguments which are passed to fprintf. 289: (override_options): Remove unsupported -mpic code. 290: 291: * tm-decstatn.h (toplevel): Add a GNU copyright. 292: 293: * tm-iris.h (toplevel): Add a GNU copyright. 294: (CPP_SPEC): If -ansi, define __EXTENSIONS__. 295: (SGI_TARGET): Define this for other mips files. 296: (LABEL_AFTER_LOC): New macro to put a label after .loc. 297: (SET_FILE_NUMBER): New macro to force .file/.loc file # to be 1. 298: (ADJUST_STACK_SIZE): Don't deal with variable arguments. 299: 300: * tm-mips.h (*_SPEC): Add #ifdef's so other files can define their 301: own, without #undef. 302: (LINK_SPEC, ASM_SPEC): Pass -EB/-EL to assembler, linker so cross 303: compilers can be made from little endian mips to big endian mips and 304: vica versa.
