From: Masahiro Yamada Date: Thu, 23 Oct 2014 16:30:41 +0000 (+0900) Subject: x86: set CONFIG_USE_PRIVATE_LIBGCC to y X-Git-Tag: v2015.01-rc1~184 X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=dd43fa22de5fcffd6325fc38633ccc71734826c7;p=oweals%2Fu-boot.git x86: set CONFIG_USE_PRIVATE_LIBGCC to y The motivation of this commit is to change CONFIG_USE_PRIVATE_LIBGCC to a boolean macro so we can move it to Kconfig. In the current implementation, there are two forms of syntax for this macro: - CONFIG_USE_PRIVATE_LIBGCC=y - CONFIG_USE_PRIVATE_LIBGCC=path/to/private/libgcc The latter is only used by x86 architecture. With a little bit refactoring, it can be converted to the former.
