Result of running IWYU (https://include-what-you-use.org/) and
applying most of the suggestions about unncessary includes and
forward declarations.
Was motivated by observing that <thread> was being included in
ppcopcodes.cpp even though it was unused (found while researching
the use of threads), but seems generally good to help with build
times and correctness.
While booting Mac OS X 10.2 installer CD, a return from RFI didn't change the instruction address virtual memory page but did change the physical memory page so we must always recalculate the physical address after RFI.
Perhaps there are other cases where this may be required?
- Subtract one so that it can't overflow to zero.
- Use page_start as the base so mask operation is not required.
- Recalculate it only when the page changes.
The same flag was being used for flushing both instruction and data TLBs so sometimes a flush for one TLB list would not occur if the flag was cleared when flushing the other TLB list.
Don't log consecutive accesses to unmapped physical memory addresses. This saves a couple hundred thousand lines in the log in some cases.
This is only a partial fix. Any access that isn't logged should be queued and output if a log message is output that is not this log message or after a time period.
- mpc601_block_address_translation will now return 0 for prot and pa when bat_hit is false (when the if statement is not positive during the for loop). The calling function doesn't care what prot and pa are when bat_hit is false, but we do this to remove the compiler warining.
- For tlb_flush_entry, the compiler thinks m might not always be in the range 0 to 5 so tlb1 and tlb2 might not get initialized by the switch statement. Add default to get around this warning.
Use explicit cast when converting large integer types to smaller integer types when it is known that the most significant bytes are not required.
For pcidevice, check the ROM file size before casting to int. We'll allow expansion ROM sizes up to 4MB but usually they are 64K, sometimes 128K, rarely 256K.
for machinefactory, change the type to size_t so that it can correctly get the size of files that are larger than 4GB; it already checks the file size is 4MB before we need to cast to uint32_t.
For floppyimg, check the image size before casting to int. For raw images, only allow files up to 2MB. For DiskCopy42 images, it already checks the file size, so do the cast after that.
