[Qemu-devel] [BUG] checkpatch.pl hangs on target/mips/msa_helper.c

[Aleksandar Markovic]

If  checkpatch.pl is applied (using switch "-f") on file 
target/mips/msa_helper.c, it will hang.

There is a workaround for this particular file:

These lines in msa_helper.c:

        uint## BITS ##_t S = _S, T = _T;                            \
        uint## BITS ##_t as, at, xs, xt, xd;                        \

should be replaced with:

        uint## BITS ## _t S = _S, T = _T;                           \
        uint## BITS ## _t as, at, xs, xt, xd;                       \

(a space is added after the second "##" in each line)

The workaround is found by partial deleting and undeleting of the code in 
msa_helper.c in binary search fashion.

This workaround will soon be submitted by me as a patch within a series on misc 
MIPS issues.

I took a look at checkpatch.pl code, and it looks it is fairly complicated to 
fix the issue, since it happens in the code segment involving intricate logic 
conditions.
