Commit 6616b2ad reverted commit 40ea285c. Looks like a mismerge to me. Signed-off-by: Markus Armbruster <armbru@redhat.com> Acked-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2010-05-22Fix tarbin Makefile ruleStuart Brady1-34/+13
The 'tarbin' Makefile rule doesn't include qemu-system-sparc64, but should do, now that sparc64-softmmu is in the default target list. The rule attempts to tar up binaries that were not built if a target list was passed to the configure script -- in which case, it will either fail, or otherwise include binaries from previous builds. Fix both problems once and for all by building a list of binaries to include in the tarball, using the list of targets to be built.

2010-05-22Put dependency files in proper subdirJan Kiszka1-1/+1
This seems to resolve subtle breakages of our build system: Dependency files generated for targets like 'dir/foo.o' were saved as 'foo.d'. Now, if there was also a target 'foo.o', one of the dependency file was overwritten. Concrete example: libhw*/macio.o vs. libhw*/ide/macio.o. And this often left a segfaulting build result behind when changing the "wrong" data structures". Fix it by generating proper 'dir/foo.d'.

2010-05-21tcg-ia64: Fix some register usage issues.Richard Henderson1-25/+42
(1) The output registers were not marked call-clobbered, even though they can be modified by called functions. (2) The thread pointer was not marked reserved. (3) R4-R6 are call-saved, but not saved by the prologue. Rather than save them, mark them reserved so that we don't use them.

2010-05-21tcg-hppa: Load GUEST_BASE as an immediate.Richard Henderson1-8/+4
Now that the prologue is generated after GUEST_BASE is fixed, we can load it as an immediate, and also avoid reserving the register if it isn't necessary. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2010-05-21alpha-linux-user: Fix sigprocmask.Richard Henderson2-5/+43
Alpha passes oldset by value in a register, and returns the newset as the return value; as compared to the standard implementation in which both are passed by reference. This requires being able to distinguish negative return values that are not errors. Do this in the same way as the Alpha Linux kernel, by storing a zero in V0 in the implementation of the syscall. At the same time, fix a think-o in the regular sigprocmask path in which we passed the target, rather than the host, HOW value.

2010-05-21tcg-i386: Tidy non-immediate arithmetic operations.Richard Henderson1-30/+48
Add more OPC values, and tgen_arithr. Use the later throughout. Note that normal reg/reg arithmetic now uses the Gv,Ev opcode form instead of the Ev,Gv opcode form used previously. Both forms disassemble properly, and so there's no visible change when diffing log files before and after the change. This change makes the operand ordering within the output routines more natural, and avoids the need to define an OPC_ARITH_EvGv since a read-modify-write with memory is not needed within TCG.

2010-05-21arm_timer: fix oneshot modeRabin Vincent1-1/+1
In oneshot mode, the delta needs to come from the TimerLoad register, not the maximum limit. Signed-off-by: Rabin Vincent <rabin@rab.in> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2010-05-21arm_timer: reload timer when enabledRabin Vincent1-1/+1
Reload the timer when TimerControl is written, if the timer is to be enabled. Otherwise, if an earlier write to TimerLoad was done while periodic mode was not set, s->delta may incorrectly still have the value of the maximum limit instead of the value written to TimerLoad. This problem is evident on versatileap on current linux-next, which enables TIMER_CTRL_32BIT before writing to TimerLoad and then enabling periodic mode and starting the timer. This causes the first periodic tick to be scheduled to occur after 0xffffffff periods, leading to a perceived hang while the kernel waits for the first timer tick.
