sync to upstream ccan.git commit ca7c5a9e04f3 ("ccan: make tal_dump()
format more regular.").
The recipe used to sync upstream is:
$ cd ccan
$ ./tools/create-ccan-tree -b make tmp \
array_size check_type container_of heap \
short_types build_assert endian list str
$ # replace directories in skiboot/ccan/ with those in tmp/ccan/
$ cd ../skiboot
$ patch -p1 < ccan/skiboot.patch
This also adds a README.skiboot to help with future updates.

/**
|
|
* array_size - routine for safely deriving the size of a visible array.
|
|
*
|
|
* This provides a simple ARRAY_SIZE() macro, which (given a good compiler)
|
|
* will also break compile if you try to use it on a pointer.
|
|
*
|
|
* This can ensure your code is robust to changes, without needing a gratuitous
|
|
* macro or constant.
|
|
*
|
|
* Example:
|
|
* // Outputs "Initialized 32 values\n"
|
|
* #include <ccan/array_size/array_size.h>
|
|
* #include <stdlib.h>
|
|
* #include <stdio.h>
|
|
*
|
|
* // We currently use 32 random values.
|
|
* static unsigned int vals[32];
|
|
*
|
|
* int main(void)
|
|
* {
|
|
* unsigned int i;
|
|
* for (i = 0; i < ARRAY_SIZE(vals); i++)
|
|
* vals[i] = random();
|
|
* printf("Initialized %u values\n", i);
|
|
* return 0;
|
|
* }
