Hello!
Attached patch fixes recent bootstrap failure on alpha-pc-linux-gnu in
in dwarf2out_var_location, at dwarf2out.c:21983.
2011-03-21 Uros Bizjak <[email protected]>
* config/alpha/alpha.c (alpha_pad_noreturn): Do not emit an unop
between a call and its CALL_ARG_LOCATION note.
Bootstrapped and regression tested on alphaev68-pc-linux-gnu. OK for
mainline SVN?
Uros.
