2020-07-13gcc-plugins: Replace HTTP links with HTTPS onesAlexander A. Klimov1-1/+1
Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

2017-01-14gcc-plugins: consolidate on PASS_INFO macroKees Cook1-5/+1
Now that PASS_INFO() exists, use it in the other existing gcc plugins, instead of always open coding the same thing. Based on updates to the grsecurity/PaX gcc plugins. Signed-off-by: Kees Cook <keescook@chromium.org>
2016-10-31gcc-plugins: Export symbols needed by gccKees Cook1-2/+2
This explicitly exports symbols that gcc expects from plugins. Based on code from Emese Revfy. Signed-off-by: Kees Cook <keescook@chromium.org>
2016-06-07Add Cyclomatic complexity GCC pluginEmese Revfy1-0/+73
Add a very simple plugin to demonstrate the GCC plugin infrastructure. This GCC plugin computes the cyclomatic complexity of each function. The complexity M of a function's control flow graph is defined as: M = E - N + 2P where E = the number of edges N = the number of nodes P = the number of connected components (exit nodes).
