Hi All,

We trying  to use clang+llvm to generate the gcc  coverage format as

clang version 3.6.0

$clang  --coverage -Xclang -coverage-cfg-checksum -Xclang
-coverage-no-function-names-in-data -Xclang -coverage-version='407*'
test.c

$a.out

$llvm-cov gcov test.gcda

Unexpected version: *704.
Invalid .gcno File!

Debugging the above cause ,But any hints from experts here ,will help a lot .

Appreciate your time ,Thank you
