Update of /home/cvs/cebix/BasiliskII/src/Unix by gbeauche Modified Files: sigsegv.cpp Log Message: - Fix SPARC Store Doubleword transfer_size in decoder. - In the instruction skipper code, add a huge kludge (trampoline) to forcibly zero out %global registers when requested. Otherwise, Solaris/SPARC turned out to use %g1 during signal handling, and the zero we could have written to there vanished. This assumes [%sp-8] is valid to use (ABI states data below %sp is undefined though) |

Update of /home/cvs/cebix/BasiliskII/src/Unix by gbeauche Modified Files: sigsegv.cpp Log Message: Code I wrote yesterday was totally broken. It's enough to make sure nPC is correctly updated too... Instruction skipper now works on Solaris/SPARC. |

Update of /home/cvs/cebix/BasiliskII/src/Unix by gbeauche Modified Files: sigsegv.cpp Log Message: MacOS X exception handling updates: - Call user handler for KERN_INVALID_ADDRESS too (SIGBUS) - Check for VALID_THREAD_STATE_FLAVOR in forward_exception() - Return KERN_FAILURE if forward_exception() got an unknown behavior code |

Update of /home/cvs/cebix/BasiliskII/src/Unix by gbeauche Modified Files: sigsegv.cpp Log Message: According to kernel sources, that is XNU 344.49 (10.2.8), XNU 517.12.7 (10.3.9), XNU 792.21.3 (10.4.10) and XNU 1228 (10.5.0), exception handler code[1] always contains the fault address nowadays. So make it the default fast path but keep provisions to check that at run-time first. This yields a nearly 4x improvement in SIGSEGV recovery but MacOS X is still suboptimal wrt. Linux, so VOSF is still not possible with frameskip == 0. XXX: the ppc kernel had bugs that caused DAR (put into code[1]) to be incorrectly decoded. This would need a broader test audience or more careful audit of the sources changes. |

Update of /home/cvs/cebix/BasiliskII/src/Unix by gbeauche Modified Files: sigsegv.cpp Log Message: Add initial support for instruction skipping on Linux/ia64. It was more complex than expected but it was fun to play with. Who designed this ISA? I'd love to see how the decoder is implemented in HW, by all means it is not "simplified" unless I missed some pattern... |

Update of /home/cvs/cebix/BasiliskII/src/Unix by gbeauche Modified Files: sigsegv.cpp Log Message: The Linux kernel actually allows to restart execution from the specified slot in the bundle. This is faster and more accurate as this avoids emulation. Also clean-up code so that to prepare the use of lib uaccess on hpux/ia64. XXX: this will need explicit use of uint64_t to define registers because HP/UX is ILP32 capable and all registers are 64-bit capable so "unsigned long" won't fit. |

Update of /home/cvs/cebix/BasiliskII/src/Unix by gbeauche Modified Files: sigsegv.cpp Log Message: Make it possible to override the Mach fault recovery scheme through an environment variable: SIGSEGV_MACH_FAULT. It can be set to "direct" to assume the fault address comes from code[1] argument, or "slow" to use the slow path through thread_get_status(EXCEPTION_STATE)->faultvaddr. |

Update of /home/cvs/cebix/BasiliskII/src/Unix by gbeauche Modified Files: sigsegv.cpp Log Message: Fix build on MacOS X Leopard. Leopard kernel faster? This is pure marketing hype. For 32-bit applications, Mach exception recovery is 60% slower. For 64-bit applications, this is up to 40% faster though. In any case, MacOS X remains pretty slow wrt. Linux... |

Update of /home/cvs/cebix/BasiliskII/src/Unix by gbeauche Modified Files: sigsegv.cpp Log Message: Use fixed-size integer types, especially for 64-bit quantities. HP-UX for IPF is essentially an ILP32 platform but machine registers are 64-bit wide. Make IA64_SET_GR() set the NaT bit at the same time as the register value. |
