travis.yml: enable linux-gcc-debug-tcg cache (2019-10-28 15:12:38 +0000)
----------------------------------------------------------------
TCG Plugins initial implementation
- use --enable-plugins @ configure
- low impact introspection (-plugin empty.so to measure overhead)
- plugins cannot alter guest state
- example plugins included in source tree (tests/plugins)
- -d plugin to enable plugin output in logs
- check-tcg runs extra tests when plugins enabled
- documentation in docs/devel/plugins.rst
----------------------------------------------------------------
