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. Regards, Aleksandar
