Joel Brobecker	4744ac1bb0	Switch the license of all files explicitly copyright the FSF to GPLv3.	19 years ago
Thiemo Seufer	14fb6c5a50	* cp1.c (value_fpr): Don't inherit existing FPR_STATE for uninterpreted formats. If fmt is one of the uninterpreted types don't update the FPR_STATE. Handle fmt_uninterpreted_32 like fmt_word, and fmt_uninterpreted_64 like fmt_long. (store_fpr): When writing an invalid odd register, set the matching even register to fmt_unknown, not the following register. * interp.c (sim_open): If STATE_MEM_SIZE isn't set then set it to the the memory window at offset 0 set by --memory-size command line option. (sim_store_register): Handle storing 4 bytes to an 8 byte floating point register. (sim_fetch_register): Likewise for reading 4 bytes from an 8 byte register. (sim_monitor): When returning the memory size to the MIPS application, use the value in STATE_MEM_SIZE, not an arbitrary hardcoded value. (cop_lw): Don' mess around with FPR_STATE, just pass fmt_uninterpreted_32 to StoreFPR. (cop_sw): Similarly. (cop_ld): Pass fmt_uninterpreted_64 not fmt_uninterpreted. (cop_sd): Similarly. * mips.igen (not_word_value): Single version for mips32, mips64 and mips16.	20 years ago
