26f9b1d38b Fix instruction skipping on MacOS X in the fast path case. 2007-12-31 18:07:01 +00:00

b5ac365858 Add support for 64-bit MacOS X for PowerPC (untested beyond "it compiles"). 2007-12-31 06:59:39 +00:00

9fa1bbd972 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.

the memory addresses that triggered a SIGSEGV (e.g. MacOS X).

25c5b9599e Update to slirp sources from QEMU 0.9.0: 
- fix UDP (Jason Wessel)
- enable TCP_NODELAY for slirp redirection (Daniel Jacobowitz)

b899d55068 Don't raise SIGPIPE, let errno be set to EPIPE. i.e. this fixes slirp ethernet 
mode with no listening port on the remote host.

d7eb0f4d6d Update to slirp sources from QEMU 0.8.2: 
- set slirp client hostname
- fix slirp redirection on systems without a useful host IP address
- separate alias_addr (10.0.2.2) from our_addr (Ed Swierk)
- fix 32+ KB packets handling (Ed Swierk)
- fix UDP broadcast translation error
- solaris port (Ben Taylor)

d83c11faa2 Host OS name representation must be large enough to handle any kind of native 
encoding (e.g. UTF-8 on MacOS X).

9000d4f54c Rewrite ExtFS support for MacOS X. This implementation uses xattrs (metadata) 
on Tiger+ to store FInfo and FXInfo. Otherwise, plain old .finfo/ helpers are
used. "Safe" flags and fields are always synchronized to/from MacOS X.

BTW, CFString leak was fixed at the same time.

7f2dfe7f4f Fix LSL & LSR instructions so that they preserve the X flags when the 
shift count is 0. Likewise for ASR + another improvement to avoid shifting
by halves (propagated bit is reset to original's when necessary).

7015458281 Fix cxmon files inclusion. Drop support for non ppc & x86 MacOS X arches.
