linux.git/scripts/hdrcheck.sh, branch master Linux kernel source tree kbuild: optimize headers_* targets 2008-07-25T20:12:16+00:00 Sam Ravnborg sam@ravnborg.org 2008-06-15T19:41:09+00:00 7712401ae9006fc9d9b9a3e7861dc73781429a89 Move the core functionality of headers_install and headers_check to two small perl scripts. The makefile is adapted to use the perl scrip and changed to operate on all files in a directory. So if one file is changed then all files in the directory is processed. perl were chosen for the helper scripts because this is pure text processing which perl is good at and especially the headers_check.pl script are expected to see changes / new checks implmented. The speed is ~300% faster on this box. And the output generated to the screen is now down to two lines per directory (one for install, one for check) so it is easier to scroll back after a kernel build. The perl scripts has been brought to sanity by patient feedback from: Vegard Nossum <vegard.nossum@gmail.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

Use dependencies for 'make headers_install'. 2006-09-24T21:15:14+00:00 David Woodhouse dwmw2@infradead.org 2006-09-24T21:15:14+00:00 de78912582bc1f95733d53e0d40779c0cd7b0686 Re-export header files only if either they or their controlling Kbuild file has actually changed. Also allow for similar dependencies with 'headers_check', once we properly create the dependencies for those. Signed-off-by: David Woodhouse <dwmw2@infradead.org>

Basic implementation of 'make headers_check' 2006-06-18T11:02:10+00:00 David Woodhouse dwmw2@infradead.org 2006-06-18T11:02:10+00:00 684753599afc76aa8f66c731bafb7204b39265b8 Based on the 'headers_install' target, this performs a basic sanity check on the exported headers -- so far only checking that they do not include any other headers which aren't selected for import, but easily extendable.
