GCC 4.4.x looks to be adding support for generating out-of-line register
|
||||
saves/restores based on:
|
||||
|
||||
http://gcc.gnu.org/ml/gcc-patches/2008-04/msg01678.html
|
||||
|
||||
This breaks the kernel build as we'd have to link with libgcc to get the
|
||||
implementation of the register save/restores.
|
||||
|
||||
To workaround this issue, we just stole the save/restore code from gcc
|
||||
and simplified it down for our needs (integer only). We only do this if
|
||||
PPC32 as gcc makes believe the linker on ppc64 will deal with this and
|
||||
only if CONFIG_CC_OPTIMIZE_FOR_SIZE is set (thus -Os).

If someone using cutting edge toolchains for ppc64 could test and make
|
||||
sure if we enable CONFIG_CC_OPTIMIZE_FOR_SIZE things work that would be
|
||||
nice.
