I saw stvx v128{0} (aligned 16-bytes store) usage on the first 16-bytes of CellSaveDataCBResult before funcStat in fw.
Also I saw 4 stw of u32{0} on it as well before funcFile, funcFixed and funcList.
So just add the resets for result before all callbacks, and make all
members of savedata_ontext 16 -byte aligned in case there are more
members guaranteed to be aligned.
* Always memset 0 setBuf->buf (to bufSize) before funcStat if the direcory is not new.
* Always memset 0 setBuf->buf (to bufSize) if listGet->dirNum became non-zero (listGet->dirListNum can be zero yet memset still occurs) .
* Clear traces of setList setup before funcStat (after funcFixed/List, only if listGet->dirNum != 0, callback can hack this value and prevent the memset).
* Check listSet->fixedListNum.
* Check listSet->fixedList for nullptr and its directory items names.
* Check listSet->focusDirName for nullptr and directory name.
* Check listSet->newData->iconPosition.
* Check listSet->newData->dirName for nullptr and directory string.
* Check statSet->setParam->parental_level for old sdk.
* Return an error if listSet->focusPosition is NEWDATA and listSet->newData is nullptr.
* Simplify savedata directory list selection.
* Allow '_' at filenames start and extension.
* Check if reading offset is valid, fix error code to CELL_SAVEDATA_ERROR_FAILURE.
* Don't create empty file on error of write ops.
* Don't allow "." and ".." filenames on funcFile, return CELL_SAVEDATA_ERROR_BROKEN.
* Ignore more warnings
These are intentional
* Signed/unsigned mismatch when comparing
* Explictly cast values
* Intentionally discard a nodiscard value
* Change ppu_tid to u32
* Do not use POSIX function name on Windows
* Qt: Use horizontalAdvance instead of width
* Change progress variables to u32
Move se_t and se_storage to util/endian.hpp
Use single template instead of two specializations.
Add minor optimization for MSVC.
Remove v128 dependency.
Try to enable intrinsics for unaligned data.
Fix minor bug in u16/u32/u64 specializations.
This routine:
1) Removes junk backup directories
2) Fixes interrupted save data process in edge case
This case can happen if emu terminates between two atomic renames.
Also use directory renaming technique for delete op.
Also rewrite recreate operation to be part of atomic process.
