* target-unicore32: switch to AREG0 free modeBlue Swirl2012-09-151-19/+19
| | | | | | | | Add an explicit CPUState parameter instead of relying on AREG0 and switch to AREG0 free mode. Tested-by: Guan Xuetao <gxt@mprc.pku.edu.cn> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
* unicore32: Close dump-option of cpu_dump_state_ucf64 functionGuan Xuetao2012-08-111-1/+1
| | | | | | | Since of tedious output, we close dump-option of cpu_dump_state_ucf64 function. Signed-off-by: Guan Xuetao <gxt@mprc.pku.edu.cn> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
* unicore32: Disintegrate cpu_dump_state_ucf64 functionGuan Xuetao2012-08-111-16/+25
| | | | | | | This patch disintegrates cpu_dump_state_ucf64 function from cpu_dump_state. Signed-off-by: Guan Xuetao <gxt@mprc.pku.edu.cn> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
* unicore32-softmmu: Make sure that kernel can access user spaceGuan Xuetao2012-08-111-10/+26
| | | | | | | | | As a matter of course, we need to access user space in kernel code, so we need to correct load/store decoders to indicate correct memory region. Signed-off-by: Guan Xuetao <gxt@mprc.pku.edu.cn> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
* unicore32-softmmu: Add coprocessor 0(sysctrl) and 1(ocd) instruction supportGuan Xuetao2012-08-111-2/+78
| | | | | | | | | | | | Coprocessor 0 is system control coprocessor, and we need get/set its contents. Also, all cache/tlb ops shoule be implemented here, but just ignored with no harm. Coprocessor 1 is OCD (on-chip-debugger), which is used for faked console, so we could output chars to this console without graphic card. TODO: curses display should be added lator for screen output.

* target-unicore32: Relicense to GPLv2+Andreas Färber2012-03-301-1/+2
| | | | | | | | | | | | | | | | | | Adopt the license text suggested by Guan Xue-tao (with a minor simplification) for all target-unicore/ files except helper.c. To helper.c Anthony Liguori contributed a qemu_malloc() -> g_malloc() conversion, still pending IBM relicensing approval, so that remains GPLv2 for now. By relicensing all possible parts now, we avoid having to formally relicense new, e.g., QOM code.

* Use hex instead of binary.Gerd Hoffmann2011-09-091-8/+8
| | | | | | | | | | Older gcc versions don't understand 0b<bits>, use hex representation instead. Fixes build failure on RHEL-5. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
* Fix conversions from pointer to tcg_target_longStefan Weil2011-08-211-1/+1
| | | | | | | | | | | | | | | | | | | tcg_gen_exit_tb takes a parameter of type tcg_target_long, so the type casts of pointer to long should be replaced by type casts of pointer to tcg_target_long. These changes are needed for build environments where sizeof(long) != sizeof(void *), especially for w64. See 4b4a72e55660abf7efe85aca78762dcfea5519ad which fixed the same issue for the other targets.

* Remove unused function parameters from gen_pc_load and rename the functionStefan Weil2011-04-201-2/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | | 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).
