Subject: [PATCH 03/11] compiler_gcc: do not redefine __gnu_attributes
|
||
|
|
|
||
|
|
gcc allows extensions to be non compiler specific by defining
|
||
|
|
__* macros for the attributes supported by gcc. Having a
|
||
|
|
different definition causes many warnings during the build
|
||
|
|
(cdefs.h on FreeBSD uses __attribute((__pure__)) where u-boot
|
||
|
|
uses __attribute__((pure)) for example). Do not redefine
|
||
|
|
these macros to suppress these warnings.
|
||
|
|
|
||
|
|
This patch ignores the checkpatch warning:
|
||
|
|
WARNING: __packed is preferred over __attribute__((packed))
|
||
|
|
|
||
