But the linker was changed to use C symbol names in linker scripts and I was told that this script in GCC would be removed in consequence. http://sourceware.org/ml/binutils/2010-12/msg00375.html Any new target macro for use only in target libraries should, in my view, be poisoned in the host system.h from the start to ensure that no-one accidentally adds definitions to the host tm.h. This would be alongside the existing /* Target macros only used for code built for the target, that have moved to libgcc-tm.h. */ #pragma GCC poison DECLARE_LIBRARY_RENAMES or just change the comment on that pragma so it doesn't imply that the macro was once defined in tm.h. -- Joseph S.
