2018-12-21target/ppc: tcg: Implement addex instructionSuraj Jitindar Singh
Implement the addex instruction introduced in ISA V3.00 in qemu tcg. The add extended using alternate carry bit (addex) instruction performs the same operation as the add extended (adde) instruction, but using the overflow (ov) field in the fixed point exception register (xer) as the carry in and out instead of the carry (ca) field. The instruction has a Z23-form, not an XO form, as follows: ------------------------------------------------------------------ | 31 | RT | RA | RB | CY | 170 | 0 | ------------------------------------------------------------------ 0 6 11 16 21 23 31 32 However since the only valid form of the instruction defined so far is CY = 0, we can treat this like an XO form instruction. There is no dot form (addex.) of the instruction and the summary overflow (so) bit in the xer is not modified by this instruction. For simplicity we reuse the gen_op_arith_add function and add a function argument to specify where the carry in input should come from and the carry out output be stored (note must be the same location).

2018-08-23fix "Missing break in switch" coverity reportsPaolo Bonzini
Many of these are marked as "intentional/fix required" because they just need adding a fall through comment. This is exactly what this patch does, except for target/mips/translate.c where it is easier to duplicate the code, and hw/audio/sb16.c where I consulted the DOSBox sources and decide to just remove the LOG_UNIMP before the fallthrough.

2017-01-24nios2: Add disas entriesMarek Vasut
Add nios2 disassembler support. This patch is composed from binutils files from commit "Opcodes and assembler support for Nios II R2". The files from binutils used in this patch are: include/opcode/nios2.h include/opcode/nios2r1.h include/opcode/nios2r2.h opcodes/nios2-opc.c opcodes/nios2-dis.c Checkpatch says total: 114 errors, 0 warnings, 3609 lines checked , which is caused by a different coding style in those files. These warnings and errors are not addressed To let these files be easily synchronized between binutils and qemu.

2017-01-24disas/cris.c: Fix Coverity warning about unchecked NULLPeter Maydell
Coverity (CID 1005689) warns that we don't check that spec_reg_info() returned non-NULL before dereferencing. Add the check, though as the comment notes this is a can't-really-happen case because the earlier constraint matching should have ruled out the "unknown reg" case.

2016-12-20Move target-* CPU file into a target/ folderThomas Huth
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.

2016-09-15Remove remainders of HPPA backendThomas Huth
The HPPA backend has been removed by the following commit: 802b5081233a6b643a8b135a5facaf14bafaa77d tcg-hppa: Remove tcg backend But some small pieces of the HPPA backend still survived until today. Since we also do not have support for a HPPA target in QEMU, we can nowadays safely remove the remaining HPPA parts (like the disassembler code, or the detection of HPPA in the configure script).

2016-07-19disas: Fix ATTRIBUTE_UNUSED define clash with ALSA headersPeter Maydell
disas/bfd.h defines ATTRIBUTE_UNUSED, but unfortunately the ALSA system headers also define this macro, which means that you can get a compilation failure if building with ALSA and any files happen to include the alsa headers before bfd.h rather than the other way around. This is unfortunate namespace pollution by the ALSA headers but we can work around it. Add an #ifndef guard to bfd.h and remove the unnecessary extra definition in disas/arm.c to fix this.

2016-05-20tci: do not include exec/exec-all.hPaolo Bonzini
TCI does not need the runtime definition in exec-all.h. It only needs the host-side definitions in tcg/tcg.h. Now that cpu.h is not included everywhere, this caused a failure because exec-all.h does need cpu.h but does not include it itself. Fix by including the intended header.
