From: Matt Turner Date: Wed, 19 Feb 2014 00:38:07 +0000 (-0800) Subject: i965/cfg: Allow cfg::dump to be called without a visitor. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=08f304bb3bfd4cc93bcc9108063afb7a8b2dd806;p=mesa.git i965/cfg: Allow cfg::dump to be called without a visitor. The fs_visitor's dump_instruction() implementation calls cfg_t() indirectly through calculate_live_intervals, so if you have an infinite loop in the CFG code, you can't call cfg::dump(fs_visitor *) to debug it.
