Change the recently added --no-includes out for --all-includes --include-headers-for-types. When I moved from --all-includes to --no-includes I missed that rules that use "type T" such as the one added dbc540c7a58 (add QSORT, 2016-09-29) won't work as intended. See [1] for a report of that. So let's move back to --all-includes to potentially scour our includes for definitions, but supply --include-headers-for-types so we won't racily emit duplicate hunks. See [2] for more discussion about that issue. This undoes most of the optimization we gained with --no-includes, using a very basic benchmark script [3] I get these results: * ~1m50s: --all-includes (before my recent patches) 38 files changed, 74 insertions(+), 78 deletions(-) * ~55s: --no-includes 27 files changed, 55 insertions(+), 57 deletions(-) * ~1m35s: --all-includes --include-headers-for-types 38 files changed, 74 insertions(+), 78 deletions(-) * ~1m20s: --local-includes --include-headers-for-types 36 files changed, 70 insertions(+), 72 deletions(-) * ~1m20s: --local-includes --include-headers-for-types --no-loops 36 files changed, 70 insertions(+), 72 deletions(-) And only the "--all-includes --include-headers-for-types" gets the same results as the previous "--all-includes", even with "--local-includes" we miss out on some definitions. 1. https://lore.kernel.org/git/3aac381e-2ce9-e35e-498c-9c26df235aed@xxxxxx/ 2. https://lore.kernel.org/git/YENdUMLTM+cerfqJ@xxxxxxxxxxxxxxxxxxxxxxx/ 3. for flags in \ '--all-includes' \ '--no-includes' \ '--all-includes --include-headers-for-types' \ '--local-includes --include-headers-for-types' \ '--local-includes --include-headers-for-types --no-loops' do git reset --hard && git clean -dxfq contrib/ time make -j8 coccicheck SPATCH_FLAGS="$flags --patch ."
