.mk files: bulk aligment and whitespace cleanup of assignments 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.

gcc: use toolchain wrapper We have a toolchain wrapper for external toolchain, but it is also beneficial for internal toolchains, for the following reasons: 1. It can make sure that BR2_TARGET_OPTIMIZATION is passed to the compiler even if a package's build system doesn't honor CFLAGS. 2. It allows us to do the unsafe path check (i.e. -I/usr/include) without patching gcc. 3. It makes it simpler to implement building each package with a separate staging directory (per-package staging). 4. It makes it simpler to implement a compiler hash check for ccache. The wrapper is reused from the external toolchain. A third CROSS_PATH_ option is added to the wrapper: in this case, the real executable is in the same directory, with the extension .real. The creation of the simple symlinks is merged with the creation of the wrapper symlinks, otherwise part of the -gcc-ar handling logic would have to be repeated. The complex case-condition could be refactored with the one for the external toolchain, but then it becomes even more complex because they each have special corner cases. For example, the internal toolchain has to handle *.real to avoid creating an extra indirection after host-gcc-{final,initial}-rebuild. Instead of creating the .real files, it would also have been possible to install the internal toolchain in $(HOST_DIR)/opt, similar to what we do for the external toolchain. However, then we would also have to copy things to the sysroot and do more of the magic that the external toolchain is doing. So keeping it in $(HOST_DIR)/usr/bin is much simpler. Note that gcc-initial has to be wrapped as well, because it is used for building libc and we want to apply the same magic when building libc.
