[U-Boot] ppc -Os and _restgpr_##_x errors
am i the only one seeing errors like: board/esd/cpciiser4/libcpciiser4.o: In function `board_early_init_f': board/esd/cpciiser4/cpciiser4.c:139: undefined reference to `_restgpr_26_x'
i'm using a gcc-4.5.x toolchain here. should we import crtsavres.S from Linux to fix this ? -mike

No, we should not. You should switch to a compiler version where this problem has been fixed. See second entry at http://www.denx.de/wiki/U-Boot/GccBugsAndIssues

thanks ... upgrading to gcc-4.6.2 from gcc-4.5.3 fixed things. when i read the gcc thread, it sounded like it wasn't optional behavior, but i guess they changed that with gcc-4.6.x. -mike

Some projects fix this manually. For example kexec adds this:
https://github.com/horms/kexec-tools/blob/master/purgatory/arch/ppc/misc.S
Not that this is a good approach....

Shouldn't libgcc provide this?

It's not being provided by certain toolchains...

Well there is a reason why one should stick to ELDK ;-)

It depends on what version of GCC you want to use as well.

If GCC generates such instruction sequences, it definitely should provide support for these in libgcc. Even better if it doesn't generate such code at all.
