Subject: [PATCH v2 5/4] Makefile/coccicheck: use --include-headers-for-types
Date: Sat, 6 Mar 2021 20:25:25 +0100 [thread overview]
Message-ID: <20210306192525.15197-1-avarab@gmail.com> (raw)
In-Reply-To: <20210305170724.23859-5-avarab@gmail.com>
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.
