New Revision: 211222
URL: http://svn.freebsd.org/changeset/base/211222
Log:
Fix crunchide to work on sparc64 and perhaps other 64 bit platforms.
I used the wrong type when setting st_name in the symbol table entry
struct. It's an Elf64_Word which is defined as an unsigned 32 bit int
on both 32 and 64 bit platforms.
To make things sensible, define some new macros to use as "word" macros
and use those, rather than simply using the explicit 32 bit macros.
