testcase

When I call memset() function from an __attribute__((transaction_safe))
function, I get compilation error.

testcase.c:10:2: error: unsafe function call 'memset' within 'transaction_safe'
function

According to Intel TM ABI, the memset() function is managed by the compiler and
it should be automatically transformed to be transaction safe.
I have attached an example.
