Author: andreast Date: Wed Nov 16 21:22:51 2011 New Revision: 227586 URL: http://svn.freebsd.org/changeset/base/227586 Log: Copy over the ASM_DECLARE_FUNCTION_SIZE macro from linux64.h. This macro declares the proper size of a function. Without this macro recent GNU as will complain about with: 'Error: .size expression for main does not evaluate to a constant.' Up to now we produce this: .L.main: .... .size main, .-main With the macro defined the output is this: .L.main: .... .size main,.-.L.main This affects only the 64-bit compiler. Tested with world and kernel on both, 32 and 64-bit powerpc.
