LLVM uses .h as its extension for header files.
Files renamed using:
for f in libcxx/test/support/*.hpp; do git mv $f ${f%.hpp}.h; done
References to the files updated using:
for f in $(git diff master | grep 'rename from' | cut -f 3 -d ' '); do
a=$(basename $f);
echo $a;
rg -l $a libcxx | xargs sed -i '' "s/$a/${a%.hpp}.h/";
done
HPP include guards updated manually using:
for f in $(git diff master | grep 'rename from' | cut -f 3 -d ' '); do
echo ${f%.hpp}.h ;
done | xargs mvim
