2011-04-20target-arm: Set Invalid flag for NaN in float-to-int conversionsPeter Maydell
When we catch the special case of an input NaN in ARM float to int helper functions, set the Invalid flag as well as returning the correct result. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-04-20hw/arm_boot.c: move initrd load address up to accommodate large kernelsPeter Maydell
Newer kernels are large enough that they can overlap the address where qemu places the initrd. Move the initrd up so that there is enough space for the kernel again. Unfortunately it's not possible to automatically determine the size of the kernel if it is compressed, so this is the best we can do.

2011-04-20Basic implementation of Sharp Zaurus SL-5500 collie PDADmitry Eremin-Solenikov
Add very basic implementation of collie PDA emulation. The system lacks LoCoMo and graphics/sound emulation.

2011-04-20Remove unused function parameters from gen_pc_load and rename the functionStefan Weil
Function gen_pc_load was introduced in commit d2856f1ad4c259e5766847c49acbb4e390731bd4. The only reason for parameter searched_pc was a debug statement in target-i386/translate.c. Parameter puc was needed by target-sparc until commit d7da2a10402f1644128b66414ca8f86bdea9ae7c. Remove searched_pc from the debug statement and remove both parameters from the parameter list of gen_pc_load. As the function name gen_pc_load was also misleading, it is now called restore_state_to_opc. This new name was suggested by Peter Maydell, thanks. v2: Remove last parameter, too, and rename the function. v3: Fix [] typo in target-arm/translate.c. Fix wrong SHA1 object name in commit message (copy+paste error).

2011-04-18s390x: virtio machine storage keysAlexander Graf
For emulation (and migration) we need to know about the guest's storage keys. These are separate from actual RAM contents, so we need to allocate them in parallel to RAM. While touching the file, this patch also adjusts the hypercall function to a new syntax that aligns better with tcg emulated code.

2011-04-17target-mips: simplify FP comparisonsAurelien Jarno
As the softfloat comparison functions already test for NaN, there is no need to always call the float*_unordered*() functions. Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-04-17target-ppc: fix SPE comparison functionsAurelien Jarno
efstst*() functions are fast SPE funtions which do not take into account special values (infinites, NaN, etc.), while efscmp*() functions are IEEE754 compliant. Given that float32_*() functions are IEEE754 compliant, the efscmp*() functions are correctly implemented, while efstst*() are not. This patch reverse the implementation of this two groups of functions and fix the comments. It also use float32_eq() instead of float32_eq_quiet() as qNaNs should not be ignored.

2011-04-17softfloat: move float*_eq and float*_eq_quietAurelien Jarno
I am not a big fan of code moving, but having the signaling version in the middle of quiet versions and vice versa doesn't make the code easy to read. This patch is a simple code move, basically swapping locations of float*_eq and float*_eq_quiet.

2011-04-17softfloat: rename float*_eq_signaling() into float*_eq()Aurelien Jarno
float*_eq_signaling functions have a different semantics than other comparison functions. Fix that by renaming float*_quiet_signaling() into float*_eq(). Note that it is purely mechanical, and the behaviour should be unchanged. Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
2011-04-17softfloat: rename float*_eq() into float*_eq_quiet()Aurelien Jarno
float*_eq functions have a different semantics than other comparison functions. Fix that by first renaming float*_quiet() into float*_eq_quiet(). Note that it is purely mechanical, and the behaviour should be unchanged. That said it clearly highlight problems due to this different semantics, they are fixed later in this patch series.

Use float64_unordered_quiet() in helper_cmptun() instead of doing the the comparison manually.

2011-04-17softfloat: use GCC builtins to count the leading zerosAurelien Jarno
Softfloat has its own implementation to count the leading zeros. However a lot of architectures have either a dedicated instruction or an optimized to do that. When using GCC >= 3.4, this patch uses GCC builtins instead of the handcoded implementation. Note that I amware that QEMU_GNUC_PREREQ is defined in osdep.h and that clz32() and clz64() are defined in host-utils.h, but I think it is better to keep the softfloat implementation self contained.
