Not really. |

One needs to use some common sense as a developer in evaluating user |
13 |
CFLAGS - because there are plenty of flags that are safe, but aren't |
14 |
listed on that page. |

Several years ago, I wrote a package that was the forerunner of the |
17 |
'Safe CFLAGS' page - genflags. It was close to unmaintable at the time |
18 |
however, so it's suffered a lot of bit-rot. With the advent of |
19 |
libcpuinfo, and x86info being written, it stands a much better chance of |
20 |
giving useful output, but that still does not supersede the common sense |
21 |
statement above. |
