Hi Richard,
I suspect the scripts were confused because there were some bugs in dg-directives during a few days, leading to random Tcl errors.
You've committed your patch by now anyway, just mentioning in case you are confused.
Thanks and sorry for the inconvenience,
Hmm actually I was confused :-)
The postcommit CI shows the same thing: gcc.target/arm/fmaxmin.c now PASSes but gcc.target/arm/vect-fmaxmin.c now FAILs. Do we want to add -funsafe-math-optimizations to it?
