From dd43fa22de5fcffd6325fc38633ccc71734826c7 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 24 Oct 2014 01:30:41 +0900 Subject: 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.
