QEMU can now work with unpatched 524 ELF dynamic loader and libc (Rusty Russell). 525 - ISO C warning fixes (Alistair Strachan) 526 - first self-virtualizable version (works only as long as the 527 translation cache is not flushed) 528 - RH9 fixes 529 530version 0.1.5: 531 532 - ppc64 support + personality() patch (Rusty Russell) 533 - first Alpha CPU patches (Falk Hueffner) 534 - removed bfd.h dependency 535 - fixed shrd, shld, idivl and divl on PowerPC. 536 - fixed buggy glibc PowerPC rint() function (test-i386 passes now on PowerPC). 537 538version 0.1.4: 539 540 - more accurate VM86 emulation (can launch small DOS 16 bit 541 executables in wine). 542 - fixed push/pop fs/gs 543 - added iret instruction. 544 - added times() syscall and SIOCATMARK ioctl. 545 546version 0.1.3: 547 548 - S390 support (Ulrich Weigand) 549 - glibc 2.3.x compile fix (Ulrich Weigand) 550 - socketcall endian fix (Ulrich Weigand) 551 - struct sockaddr endian fix (Ulrich Weigand) 552 - sendmsg/recvmsg endian fix (Ulrich Weigand) 553 - execve endian fix (Ulrich Weigand) 554 - fdset endian fix (Ulrich Weigand) 555 - partial setsockopt syscall support (Ulrich Weigand) 556 - more accurate pushf/popf emulation 557 - first partial vm86() syscall support (can be used with runcom example). 558 - added bound, cmpxchg8b, cpuid instructions 559 - added 16 bit addressing support/override for string operations 560 - poll() fix 561 562version 0.1.2: 563 564 - compile fixes 565 - xlat instruction 566 - xchg instruction memory lock 567 - added simple vm86 example (not working with QEMU yet). The 54 byte 568 DOS executable 'pi_10.com' program was released by Bertram 569 Felgenhauer (more information at http://www.boo.net/~jasonp/pipage.html). 570 571version 0.1.1: 572 573 - glibc 2.2 compilation fixes 574 - added -s and -L options 575 - binary distribution of x86 glibc and wine 576 - big endian fixes in ELF loader and getdents. 577 578version 0.1: 579 580 - initial public release. 581
