* Print a warning if config for VM was NULL.
* Add warning if register is not added to VM due to overlap.
* Update PPC register profile.
* Add vector and float registers. As well as some control and system registers.
* Enable to write values 4bit registers.
* PPC: Uplift most common instructions.
* Print warning if reserved SPR instruction is encountered.
* Update PC/LR addresses and add ca32 writes.
* Write cache needs to get flushed so load and store tests don't share the same memory.
* Add missing T/F branch mnemonics.
* Add Move to/from CR/CR0-7
* Fix TA address calculation for branch instructions.
* Add branch tests for branch mnemonics.
* Add XNOP
* NOP cache touch instructions.
* Add undocumented ATTN instruction to the not_implemented group.
* Add isel instruction.
* Implement CRCLR, CRSET, CROR.
* Add CNTLZ instructions.
* Add mcrf instructions.
* Add inacive test for cmpb.
* Add Load bytes reverse instructions.
* Add test and add address alignment to dcbz.
* Add eqv test
* Correct DIV and MUL operations
* Add div tests.
* Add tests and correct MT/MFXER
* Remove register ca32, ov32
* Remove explici setting of cr register because QEMU does not do it. Otherwise we get a mismatch in the trace
* Simplify carry set for add and sub. Sub instructions are exclusivly defined with addition. Hence no sub case needed.
* Unify BD and fix branch instructions. Fix: Check the single bit not the cr reg
* Document Conditional branches and replace NOPs with EMPTY
* Add mulli instruction to double word instructions.
* Fix ca set for shift instructions:
* ca value had to be determined before the shift happened. The wrong ca value was calculated if the src and target reg were the same.
* Replace NOP wit EMPTY.
* Use MSB isntead of SLT.
* Brought fixup of ADD and SUB instructions: The add and sub instructions had several issues which let to incorrect execution.
* The carry was incorrectly if three add operations happened (only the last add were checked, not both).
* The carry was incorrectly set if the src and target register matched.
* Same applies for the CR bit.
* It was too complex. Several local variables were introduced for this.
* Set result in local var, since it would change if src and target reg are the same.
* Remove MTMSR and MFMSR since it is too complex and untestable currently.
* Use unsigned int for shift. Otherwise the 0x1c shift produces a runtime error since 0xf is int as default.
* Fix mtxer: Only write flag bits.
* Let NOT_IMPLEMENTED macro return NULL.
* Mark st[wd]cx and l[wd]cx as not implemented.
* Increase dcache_line_size to 128 bytes.
* Fix cntlz for ppc32. m was set incorrectly, since it is 0 not 32 for 32bit cpus.
* Fix isel: Use op.crx reg instead of imm.
* Unify helper function names: Prependnig `ppc_` mark as IPI
* Add more "Move to SPR" cases.
* MULLI opeartes only on double word on 64bit CPUs.
* Most registers are now assigned the control register type and no longer show up in the ar command.
* Fix xor if dest and src registers match by saving result in local var.
* Fix BE/LE issue for Load BRX instructions.
* Fix shifts: Use only lower 6bits of n.
* User Pure local variables for ROT macros.
* Fix rldimi instructions.
* n was not inverted.
* more than 6 bits of n could be used
* Add 32bit emulateme tests.
* Add 64bit emulateme tests.
* Determine lg(v) in inline function.
* Calculate CR bit in C not in the VM.
* Check if `~mask = 0` and skip mask calculation if yes.
* Check for `sh == 0` and skip rotations where possible.
* Remove `la` instruction. `la` is a mnemonic for `addi`.
* Remove SPR instructions which are not supported by QEMU or not traced yet. For most set/read SPR instructions QEMU segfaults.
In case of SPR 1 (xer), 8 (lr) and 9 (ctr) the assembler resolves them to their mnemonics (mtxer, mtlr etc.). This means the code here is never reached.
To test the get_xer code MFXER was added again. The rz-tracetests will fail for this instructions (due to missing ca32, ov32). But this case is covert in an issue.
* Show group-level details of commands
Details can be defined at either a group command or its subcommand of
the same name. If define on group-level it will also be shown in the
group help without needing ??.
* Fix > $ redirection for errored command and leak
* Rewrite ar and dr commands with newshell
Breaking changes:
ar* => arf, ar- => arf-, ar. => ar*
ar, => art, ar? => arq
ar0 => ara0, arb => arab, ars => araS
arC => arpC
arn => arR
art => arT
arf => arF
Removed: drm, aer
* Reduce recursion when analyzing function control-flow
* Jump table refactoring
* Use rz_ prefix for the API
* Use struct instead of long parameter list
* Add `analysis.jmp.tblmax` to configure maximun amount of cases to analyze
* Remove recursion
* Disable `asm.bytes` by default
* Fix tests by adding `e asm.bytes=true` (1/n)
* Fix tests by adding (2/n)
* Fix tests by adding `e asm.bytes=true` (3/n)
* Fix tests by adding `asm.bytes=true` (4/n)
* Fix test by adding `asm.bytes=true` (5/n)
* Fix mostly all broken tests
* Attemp to fix the rzpipe test
* Attempt to fix the tests in `db/cmd/cmd_pipe`
* Fix tests again
* Fix cmd_pipe test
* Add a test where `asm.bytes` is false
