Lioncash	6d80445fe1	unicorn_arm: Treat registers as unsigned values in casts ... It isn't particularly advisable to treat these as signed values, given the registers themselves have no notion of signedness associated with them.	2019-04-26 08:48:31 -04:00
Lioncash	f419015aa3	unicorn_arm: Don't steamroll CPSR bits defined as RAZ/SBZP ... Prevents bits from being set that should always read as zero according to the ARM architecture reference manual.	2019-04-26 08:47:50 -04:00
Lioncash	14f1cb03e9	target/arm/unicorn_arm: Get rid of magic constants where applicable	2019-04-19 20:23:41 -04:00
yhql	1723cb1015	Add ARM MSP, PSP and CONTROL register access (#1071) ... Necessary for NVIC exception emulation from user. Backports commit 31851280316d37305f412fff42f45bb375999074 from unicorn	2019-03-08 02:24:49 -05:00
cfrantz	5ad3a0ea82	Add support for the ARM IPSR register. (#1067) ... 1. Create an enum name for the IPSR register. 2. Implement read and write of the IPSR via the xpsr helper functions. Fixes #1065 Backports commit 6c319941a5462ee3a4af4593c371f5674394d6ce from unicorn.	2019-02-28 16:40:54 -05:00
MerryMage	9b87d0f61a	unicorn_arm: Allow for read/write of UC_ARM_REG_FPSCR	2018-09-03 21:03:55 +01:00
MerryMage	896a8e1320	unicorn_arm: Use ARM offset not ARM64 offset ... Was introduced by 5439b4a542	2018-09-03 07:44:29 +01:00
Eduardo Habkost	a7f59d7771	Use DEFINE_MACHINE() to register all machines ... Convert all machines to use DEFINE_MACHINE() instead of QEMUMachine automatically using a script. Backports commit e264d29de28c5b0be3d063307ce9fb613b427cc3 from qemu	2018-03-11 15:12:46 -04:00
Lioncash	5439b4a542	unicorn/aarch64: Use qemu-provided helpers for accessing VFP/NEON/SIMD registers ... Avoids directly touching the representation of the VFP/NEON/SIMD registers	2018-03-07 11:25:41 -05:00
Lioncash	441f3b73da	unicorn_arm: Use ARM_CPU macro instead of a direct cast in arm_release ... Makes the code more reliant on qemu instead of manually doing our own thing	2018-03-07 10:24:21 -05:00
Lioncash	d0abc23e99	unicorn/arm: use uc->cpu instead of uc->current_cpu ... Keeps cpu variable usage consistent. Also eliminates unnecessary casts	2018-03-07 10:15:49 -05:00
Lioncash	890f234a53	unicorn/aarch64: Lessen the amount of ARMCPU macro usages ... This macro can just be used once per function that it's used in, reducing the overall amount of line noise in register reading and writing	2018-03-07 09:59:27 -05:00
Thomas Huth	b2f1326437	Move target-* CPU file into a target/ folder ... We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead. Backports commit fcf5ef2ab52c621a4617ebbef36bf43b4003f4c0 from qemu	2018-03-01 22:50:58 -05:00
