1996-09-18 * config/obj-coff.c (obj_coff_endef): Both versions: Move C_STATIan Lance Taylor1-37/+36
symbols to the position of the debugging information. PR 10668.
1996-09-10Don't set interlocks for r5000. Rely on -mips4 settings.Ian Lance Taylor1-6/+2
1996-09-09 * config/tc-mips.c (append_insn): Don't swap an instruction whichIan Lance Taylor1-11/+20
sets a condition code with an instruction which uses a condition code. (mips_ip): In cases 'N' and 'M', look for $fccN rather than an immediate value.

mips_cpu is 5000, set interlocks and cop_interlocks. (mips_ip): Give a better error message if the ISA level is wrong. (md_parse_option): Recognize -mcpu=[v][r]5000.

* config/tc-mips.c (COUNT_TOP_ZEROES): Added macro to count leading zeroes. (load_register): Ensure hi32 bits are not lost during lo32bit processing. Fix shift offset that was overflowing into the next instruction field. Add code to generate shorter sequences for constants with a single contiguous seqeuence of ones. Fri Sep 6 18:23:54 1996 James G. Smith <jsmith@cygnus.co.uk> * gas/mips/dli.{s,d}: More test cases added. NOTE: The COUNT_TOP_ZEROES macro is a bit bulky, and the same result can be achieved by using a "standard" ffs() routine: count = ffs(~v); count = count == 0 ? 0 : 33 - count; However the following timings (VR4300 CPU clock ticks on a CMA101 board) show the performance gain. Number of ffs() for loop if/then/else conditional leading ?: zeroes ------------------------------------------------------------------------------- 0 167 179 266 251 1 1718 283 263 259 2 1670 379 287 295 3 1622 475 311 311 4 1574 571 295 287 5 1534 667 311 319 6 1478 763 307 299 7 1430 859 323 323 8 1382 962 287 295 9 1334 1051 319 311 10 1286 1154 299 307 11 1238 1250 323 331 12 1183 1346 299 307 13 1135 1442 331 323 14 1087 1546 311 319 15 1039 1642 335 343 16 991 1730 295 287 17 950 1834 311 319 18 895 1922 307 299 19 847 2026 331 323 20 799 2122 307 299 21 751 2218 323 323 22 703 2314 311 311 23 655 2417 343 335 24 599 2506 307 299 25 559 2602 331 331 26 511 2705 311 319 27 463 2801 343 335 28 407 2897 311 319 29 367 2993 343 335 30 311 3097 323 331 31 271 3185 355 355 32 215 3233 379 371

* config/tc-mips.c (load_register): Remove unnecessary code that was causing the high 32bits of 64bit constants to be lost. Fixes PR10503. The compiler was producing the assembler code: dli $3,0xfffffffffffff when constructing the softfloat library. Unfortunately it was being incorrectly assembled.

opcode doesn't want a register, then we don't have a match. (md_assemble): Get size of the instruction from the opcode table. So we choose the right opcode and so that we get the sizes right.
