If checkpatch.pl is applied (using switch "-f") on file
target/mips/msa_helper.c, it will hang.
This is a workaround by correcting the source file. The workaround is
found by partial deleting and undeleting of the code in msa_helper.c
in binary search fashion.
The bug (for checkpatch.pl) is already reported to the qemu-devel list.

Hi, Paolo,
It was an incredibly fast fix! :)
I already confirmed that the fix fixes the problem on msa_helper.c. I would nevertheless like to have this workaround applied. Can you perhaps give it "Reviewed-by"?

Aleksandar

I'm not sure it's worth having this but you are the maintainer so your
choice :) What is unclear to me is, while changing this, why only fix
the suffix and not also the prefix? That is:
uint<space>## BITS ##<space>_t S = _S, T = _T;

If someone in future peruses an older version of this file (let's say, while working on an older version of QEMU), and comes across this problem with checkpatch.pl, by checking the full history of the file, they would be able to see what the problem is. Without this patch, they wouldn't.

It wouldn't be clear what characters caused the problem (or triggered the bug, if you wish).

Aleksandar

Update CP0 registers Config0, Config1, and Config5 bit definitions.
Some of these bits will be utilized by upcoming nanoMIPS changes.

Remove "range style" case statements to make code analysis easier.
This is needed also for some upcoming nanoMIPS-related refactorings.

WatchHi is extended by the field MemoryMapID with the GINVT instruction.
The field is accessible by MTHC0/MFHC0 in 32-bit architectures and DMTC0/
DMFC0 in 64-bit architectures.

Did you in fact want the high-part sign-extended as well?
It might be more obvious to write
return sextract64(env->CP0_WatchHi[sel], 32, 32);
in that case.

Cleaner as
env->CP0_WatchHi[sel] = deposit64(env->CP0_WatchHi[sel], 32, 32, arg1);
For future cleanup, there is nothing in this (or several other) that requires
writing helper code. This could just as easily be expanded inline with one
single load or store operation.

If this all is the case, I am going to remove this patch from this series. There is no hurry. This patch just needs to be thought over a little bit more. It will be sent in some future series.

MFHC0 and MTHC0 used to handle EntryLo0 and EntryLo1 registers only,
and placing ELPA flag checks befor switch statement were technically
correct. However, after adding handling more registers, these checks
should be moved to act only in cases of handling EntryLo0 and
EntryLo1.
