Revert "GCC4.6: Convert various empty macros to inline functions" 2011-10-04T19:19:19+00:00 Wolfgang Denk wd@denx.de 2011-10-04T19:19:19+00:00 f092f15d39d1a223b240eb83dc3f4c64a02a8ea6 This reverts commit 60ce53cf9f408d9ad721f8e7a87d6a564e6d5bac. The commit causes build breakage for a number of boards. This results from the fact that now the arguments of debug() actually get referenced (even if there is hope that the compiler will optimize away the debug() call). The obvious fix to that probem (change the code to always declare the referenced variables and data structures) increases the code size, and was this rejected. So it was decided to revert this commit until a better solution is found.
