Add GPLv2 notices to files from UAE Amiga Emulator, as retrieved from the COPYING file of uae-0.8.29, retrieved from http://www.amigaemulator.org/ via uae-0.8.29.tar.bz2 (MD5 = 54abbabb5e8580b679c52de019141d61).
Fix MOVEC for 68020/68030 emulation (MSP & ISP are supported control regs).
fix stack alignment (theoritically but it was OK in practise) in generated functions, move m68k_compile_execute() to compiler/ dir since it's JIT generic and it now depends on USE_PUSH_POP (as it should)
Much improved responsiveness on NetBSD systems. On those systems, it's really hard to get high resolution timings and the system oftens fails to honour a timeout in less than 20 ms. The idea here is to have an average m68k instruction count (countdown quantum) that triggers real interrupt checks. The quantum is calibrated every 10 ticks and has a 1000 Hz resolution on average.
Enable FLIGHT_RECORDER for generated code but don't record registers in that case (yet).
revive and fix almost two-year old port to x86_64
Remove obsolete CFLOW_* constants but keep cpuop_{begin,end} for an
inline-threaded core.
- Optimize use of quit_program variable. This is a real boolean for B2. - Remove unused/dead code concerning surroundings of (debugging). - m68k_compile_execute() is generated and optimized code now.
- Changes to support 68040 -> x86 dynamic translator - Globalize FLIGHT_RECORDER, possibly used in compiler/ sources as well
Updates for new FPU core architecture
Use B2_mutex instead of pthread mutexes when ENABLE_EXCLUSIVE_SPCFLAGS is
set. However, this is not used at the moment. Is there an advantage? People
may want to add arch-optimized SPCFLAGS_{SET,CLEAR}.
- Merge with Basilisk II/JIT cpu core, interpretive part for now - Clean use of USE_PREFETCH_BUFFER macro and dependent bits
- When X86_ASSEMBLY is set, aka when cpuopti is used, do call the instruction handler by hand and make sure to save %ebp too - Really merge cpu core with uae-0.8.21: - Trace mode fixes (Bernd Roesch & Bernd Schmidt) - Reintegrate PTEST and PFLUSH instructions back as no-ops
- Close log file
- Add Flight Recorder for m68k too. That helps. ;-)
- merged some code from uae-0.8.16
- removed old JIT compiler, its related support functions and files
(compiler.{h,cpp})
- changed set/get PC to better reflect direct or real addressing modes
- updated init_m68k with fpu_init() and fpu_set_integral_fpu() calls - added exit_m68k() and handle deinitialization of the FPU - updated m68k_reset to call fpu_reset()
- imported UAE CPU 0.8.10 changes - new utility functions Mac_memset, Mac2Host_memcpy, Host2Mac_memcpu and Mac2Mac_memcpy - extfs.cpp: fixed bug in fs_rename() and fs_cat_move() (auxiliary IOParam block was not in Mac address space) - some provisions for using UAE CPU compiler (doesn't work yet)
- removed MemoryDispatch() replacement; routine from ROM is now used if possible - rom_patches.cpp: check for double PACK 4 resources; if only one is found, assume that the ROM requires an FPU and issue a warning if FPU emulation is turned off - UAE CPU opcode routines no longer return the cycle count - main_unix.cpp: pressing Ctrl-C dumps the UAE CPU state before entering mon - sys_unix.cpp: under Linux, partition sizes are read with BLKGETSIZE instead of llseek()
- new SPARC optimizations from Gwenole
- added some 68040 instructions: CINV, CPUSH, MOVE16 (Ax)+,(Ay)+, MOVEC regs, and FPU state frames; enough to boot MacOS - CPU type can be selected in GTK prefs editor
