2017-01-27ccache: Patch to fix toolchain-wrapper's --sysrootBrandon Maier
ccache doesn't rewrite the --sysroot base_dir from toolchain-wrapper correctly. Resulting in a large number of cache misses when building from different base directories. A fix has already been accepted to the ccache upstream[1], but won't be released until ccache 3.4. (Was noted as an improvement, so unsure of the 3.4 release timing) [1] https://github.com/ccache/ccache/pull/132 Signed-off-by: Brandon Maier <brandon.maier@rockwellcollins.com> Signed-off-by: Matt Weber <matthew.weber@rockwellcollins.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

2015-10-04ccache: use mtime for external toolchain, CONF_OPTS for internal toolchainArnout Vandecappelle
Our current ccache disables hashing of the compiler executable itself, because using the default 'mtime' doesn't work in buildroot: we always rebuild the compiler, so the mtime is always different, so the cache always misses. However, in the current situation, if a user changes the compiler configuration (which would result in the compiler generating different object files than before) and does 'make clean all', ccache may in fact reuse object files from the previous run. This rarely gives problems, because (1) the cache expires quite quickly (it's only 1GB by default), (2) radically changing compiler options will cause cache misses because different header files are used, (3) many compiler changes (e.g. changing -mtune) have little practical effect because the resulting code is usually still compatible, (4) we currently don't use CCACHE_BASEDIR, and almost all object files will contain an absolute path (e.g. in debug info), so when building in a different directory, most of it will miss, (5) we do mostly build test, and many of the potential problems only appear at runtime. Still, when ccache _does_ use the wrong cached object files, the effects are really weird and hard to debug. Also, we want reproducible builds and obviously the above makes builds non-reproducible. So we have a FAQ entry that warns against using ccache and tells the user to clear the cache in case of problems. Now that ccache is called from the toolchain wrapper, it is in fact possible to at least use the 'mtime' compiler hash for the external toolchain and for the host-gcc. Indeed, in this case, the compiler executable comes from a tarball so the mtime will be a good reference for its state. Therefore, the patch (sed script) that changes the default from 'mtime' to 'none' is removed. For the internal toolchain, we can do better by providing a hash of the relevant toolchain options. We are only interested in things that affect the compiler itself, because ccache also processes the header files and it doesn't look at libraries because it doesn't cache the link step, just compilation. Everything that affects the compiler itself can nicely be summarised in $(HOST_GCC_FINAL_CONF_OPTS). Of course, also the compiler source itself is relevant, so the source tarball and all the patches are included in the hash. For this purpose, a new HOST_GCC_XTENSA_OVERLAY_TAR is introduced. The following procedure tests the ccache behaviour: Use this defconfig: BR2_arm=y BR2_CCACHE=y make readelf -A output/build/uclibc-1.0.6/libc/signal/signal.os -> Tag_CPU_name: "ARM926EJ-S" Now make menuconfig, change variant into BR2_cortex_a9 make clean; make readelf -A output/build/uclibc-1.0.6/libc/signal/signal.os -> Tag_CPU_name: "ARM926EJ-S" should be "Cortex-A9" After this commit, it is "Cortex-A9".

2014-10-07.mk files: bulk aligment and whitespace cleanup of assignmentsThomas De Schampheleire
The Buildroot coding style defines one space around make assignments and does not align the assignment symbols. This patch does a bulk fix of offending packages. The package infrastructures (or more in general assignments to calculated variable names, like $(2)_FOO) are not touched. Alignment of line continuation characters (\) is kept as-is. The sed command used to do this replacement is: find * -name "*.mk" | xargs sed -i \ -e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*$#\1 \2#' -e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*\([^\\]\+\)$#\1 \2 \3#' -e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*\([^\\ \t]\+\s*\\\)\s*$#\1 \2 \3#' -e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\(\s*\\\)#\1 \2\3#' Brief explanation of this command: ^\([A-Z0-9a-z_]\+\) a regular variable at the beginning of the line \([?:+]\?=\) any assignment character =, :=, ?=, += \([^\\]\+\) any string not containing a line continuation \([^\\ \t]\+\s*\\\) string, optional whitespace, followed by a line continuation character \(\s*\\\) optional whitespace, followed by a line continuation character Hence, the first subexpression handles empty assignments, the second handles regular assignments, the third handles regular assignments with line continuation, and the fourth empty assignments with line continuation. This expression was tested on following test text: (initial tab not included) FOO = spaces before FOO = spaces before and after FOO = tab before FOO = tab and spaces before FOO = tab after FOO = tab and spaces after FOO = spaces and tab after FOO = \ FOO = bar \ FOO = bar space \ FOO = \ GENIMAGE_DEPENDENCIES = host-pkgconf libconfuse FOO += spaces before FOO ?= spaces before and after FOO := FOO = FOO = FOO = FOO = $(MAKE1) CROSS_COMPILE=$(TARGET_CROSS) -C AT91BOOTSTRAP3_DEFCONFIG = \ AXEL_DISABLE_I18N=--i18n=0 After this bulk change, following manual fixups were done: - fix line continuation alignment in cegui06 and spice (the sed expression leaves the number of whitespace between the value and line continuation character intact, but the whitespace before that could have changed, causing misalignment. - qt5base was reverted, as this package uses extensive alignment which actually makes the code more readable. Finally, the end result was manually reviewed. Signed-off-by: Thomas De Schampheleire <thomas.de.schampheleire@gmail.com> Cc: Yann E.

2014-06-14ccache: provide capability to do initial ccache setupDanomi Manchego
For example, if your project is known to require more space than the default max cache size, then you might want to increase the cache size to a suitable amount using the -M (--max-size) option. The string you specify here is passed verbatim to ccache. Refer to ccache documentation for more details. These initial settings are applied after ccache has been compiled.

2014-06-14ccache: change default cache directory path to match config settingDanomi Manchego
Commit 433290761fceb476b095548eec10adf72405e050 changed the hard-coded ccache directory location to use BR_CACHE_DIR (then BUILDROOT_CACHE_DIR), which is exported by Makefile based on the BR2_CCACHE_DIR config option. This allowed the cache location to be changed on-the-fly by setting a "make" command line variable, but left the default location of ccache's normal default at "$HOME/.ccache". Since this location does not match the default for BR2_CCACHE_DIR, it is basically almost never correct, so direct invocation of ccache outside of the buildroot Makefile, such as for increasing the cache size, becomes cumbersome. This patch changes the last-ditch cache location from "$HOME/.ccache" to the BR_CCACHE_DIR value defined when host-ccache is configured. Note that the ability to later override the cache location by using a BR_CACHE_DIR command line variable is left intact.

2014-01-10deprecated handling: introduce BR2_DEPRECATED_SINCE_xxxx_xxThomas De Schampheleire
In order to keep better track of when a feature got deprecated, and hence when it can be removed, a new set of symbols BR2_DEPRECATED_SINCE_xxxx_xx is introduced. These symbols are automatically selected when BR2_DEPRECATED is selected, and thus are transparent to the user. A deprecated feature will no longer depend on BR2_DEPRECATED directly, but rather on the appropriate BR2_DEPRECATED_SINCE_xxxx_xx. If that symbol does not yet exist, it has to be created in Config.in. When removing a deprecated feature, one should also check whether this was the last feature using the BR2_DEPRECATED_SINCE_xxxx_xx symbol, in which case the latter can be removed from Config.in. A followup patch will make sure the overview is added to the list of deprecated features in the manual, so that a buildroot core developer can easily determine which features to remove in a given development cycle.

2013-08-10host-ccache: turn into a proper dependencyThomas De Schampheleire
This patch moves the host-ccache build target from BASE_TARGETS in Makefile to an actual host prerequisite in support/dependencies. This causes host-ccache to be built as part of the dependencies, before any real package is built. Since the dependencies are built without ccache anyway, there is no need to set HOST_CCACHE_CONF_ENV anymore.

2012-05-18ccache: allow dynamic selection of cache directoryThomas De Schampheleire
The existing ccache infrastructure sets the cache directory hardcoded in the ccache binary. As this directory was set to ~/.buildroot-ccache, the cache is not necessarily local (e.g. in corporate environments the home directories may be mounted over NFS.) Previous versions of buildroot did allow to set the cache directory, but this was also hardcoded (so you had to rebuild ccache to change it), plus that support was removed. See http://lists.busybox.net/pipermail/buildroot/2011-July/044511.html for a discussion on this. This patch modifies ccache to respect a new shell variable (exported from the Makefile, based on a configuration option) instead of CCACHE_DIR. The name CCACHE_DIR itself is already used by autotargets for the ccache package.

2012-03-08ccache: set COMPILERCHECK to 'none'Thomas Petazzoni
This allows ccache to re-use its cache contents even if the compiler binary mtime has changed. It is the simplest approach to solve this problem, and it works for the internal, external and crosstool-ng toolchain backends. Of course, it leaves the user responsible for invalidating the cache when necessary, but there doesn't seem to be a real good solution that allows both to: 1/ keep the cache contents accross builds and re-use it and 2/ invalidate the cache automatically when the compiler chances in an incompatible way.

2012-03-08ccache: Force ccache to use its internal zlibThomas Petazzoni
The problem is that without this, ccache would link against the zlib of the build system, but we might build and install a different version of zlib in $(O)/host afterwards, which ccache will pick up. This might break if there is a version mismatch. A solution would be to add host-zlib has a dependency of ccache, but it would require tuning the zlib .mk file to use HOSTCC_NOCCACHE as the compiler. Instead, we take the easy path: tell ccache to use its internal copy of zlib, so that ccache has zero dependency besides the C library. Fixes bug #4808.
