Hello!
We have to apply the same DECL_UID change as in tree-stdarg.c to
alpha_stdarg_optimize_hook.
2012-08-11 Uros Bizjak <ubiz...@gmail.com>
* config/alpha/alpha.c (alpha_stdarg_optimize_hook): Shift DECL_UID
in the va_list_vars bitmap by num_ssa_names.
Tested on alphaev68-pc-linux-gnu, committed to mainline SVN as obvious.
Uros.
