2019-02-17ppc: fix crash during branch steppingRoman Kapl
The PPC BRANCH exception could bubble up, but this is an QEMU internal exception and QEMU then crased. Instead it should trigger TRACE exception, according to PPC 2.07 book. It could happen only when using branch stepping, which is not commonly used. Change gen_prep_dbgex do do trigger TRACE. The excp, argument is now removed, since the type of exception can be inferred from the singlestep_enabled flags. removed the guards around gen_exception, since they are unnecessary.

2019-02-17target/ppc: Fix msync to do what hardware doesBALATON Zoltan
According to BookE docs, invalid bits (while undefined behaviour) should not raise exception but be ignored. This seems to be implementation dependent though and QEMU currently does what e500 CPUs do and raise exception for invalid bits. Unfortunately some versions of libstdc++ (and so all programs compiled with it) have lwsync on PPC440 which is invalid but on real hardware it's just executed as msync ignoring the invalid bits (maybe that's why it got undetected) but they fail on QEMU. This patch changes invalid mask of msync to allow these programs to run but keep generating exception on e500 cores to follow what hardware does.

2019-02-17target/ppc: Enable reporting of SPRs to GDBFabiano Rosas
This allows reading and writing of SPRs via GDB: (gdb) p/x $srr1 $1 = 0x8000000002803033 (gdb) p/x $pvr $2 = 0x4b0201 (gdb) set $pvr=0x4b0000 (gdb) p/x $pvr $3 = 0x4b0000 The `info` command can also be used: (gdb) info registers spr For this purpose, GDB needs to be provided with an XML description of the registers (see the gdb-xml directory for examples) and a set of callbacks for reading and writing the registers must be defined. The XML file in this case is created dynamically, based on the SPRs already defined in the machine. This way we avoid the need for several XML files to suit each possible ppc machine. The gdb_{get,set}_spr_reg callbacks take an index based on the order the registers appear in the XML file. This index does not match the actual location of the registers in the env->spr array so the gdb_find_spr_idx function does that conversion. Note: GDB currently needs to know the guest endianness in order to properly print the registers values. This is done automatically by GDB when provided with the ELF file or explicitly with the `set endian <big|little>` command.

2019-01-09target/ppc: move FP and VMX registers into aligned vsr register arrayMark Cave-Ayland
The VSX register array is a block of 64 128-bit registers where the first 32 registers consist of the existing 64-bit FP registers extended to 128-bit using new VSR registers, and the last 32 registers are the VMX 128-bit registers as show below: 64-bit 64-bit +--------------------+--------------------+ | FP0 | | VSR0 +--------------------+--------------------+ | FP1 | | VSR1 +--------------------+--------------------+ | ... | ... | ... +--------------------+--------------------+ | FP30 | | VSR30 +--------------------+--------------------+ | FP31 | | VSR31 +--------------------+--------------------+ | VMX0 | VSR32 +-----------------------------------------+ | VMX1 | VSR33 +-----------------------------------------+ | ... | ... +-----------------------------------------+ | VMX30 | VSR62 +-----------------------------------------+ | VMX31 | VSR63 +-----------------------------------------+ In order to allow for future conversion of VSX instructions to use TCG vector operations, recreate the same layout using an aligned version of the existing vsr register array. Since the old fpr and avr register arrays are removed, the existing callers must also be updated to use the correct offset in the vsr register array. This also includes switching the relevant VMState fields over to using subarrays to make sure that migration is preserved.

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).
