Hi all, After merging the compiler-attributes tree, today's linux-next build (powerpc ppc64_defconfig) failed like this:
arch/powerpc/boot/main.c:153:45: error: expected '=', ',', ';', 'asm' or
'__attribute__' before '__section'
153 | static char cmdline[BOOT_COMMAND_LINE_SIZE]
__section(__builtin_cmdline);
| ^~~~~~~~~
arch/powerpc/boot/main.c: In function 'prep_cmdline':
arch/powerpc/boot/main.c:166:6: error: 'cmdline' undeclared (first use in this
function)
166 | if (cmdline[0] == '\0')
| ^~~~~~~
arch/powerpc/boot/main.c:166:6: note: each undeclared identifier is reported
only once for each function it appears in
arch/powerpc/boot/main.c: In function 'start':
arch/powerpc/boot/main.c:196:40: error: 'cmdline' undeclared (first use in this
function)
196 | if ((loader_info.cmdline_len > 0) && (cmdline[0] == '\0'))
| ^~~~~~~
Caused by commit
e81c903fb9e2 ("powerpc: prefer __section and __printf from
compiler_attributes.h")
I have reverted that commit for today.
gcc v9.2.1 (in case that matters)
The above error is from the PowerPC boot wrapper that is built without
the kernel headers (mainly, I think).
