Laurent Vivier	f7ef6b49a8	target-m68k: add FPCR and FPSR ... Backports commit ba62494483ab51ee31c70952b6ce5171a31860b1 from qemu	2018-03-03 19:51:31 -05:00
Laurent Vivier	1c6b1e2b9f	target-m68k: use floatx80 internally ... Coldfire uses float64, but 680x0 use floatx80. This patch introduces the use of floatx80 internally and enables 680x0 80bits FPU. Backports commit f83311e4764f1f25a8abdec2b32c64483be1759b from qemu	2018-03-03 19:35:17 -05:00
Laurent Vivier	92555a1134	target-m68k: initialize FPU registers ... on reset, set FP registers to NaN and control registers to 0 Backports commit f4a6ce5155aab2a7ed7b9032a72187b37b3bfffe from qemu	2018-03-03 18:51:37 -05:00
Laurent Vivier	ce25609ed3	target/m68k: implement rtd ... Add "Return and Deallocate" (rtd) instruction. RTD #d (SP) -> PC SP + 4 + d -> SP Backports commit 18059c9e1648bf4fc5c7c1bae6f54690742b05ba from qemu	2018-03-03 14:27:01 -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
