Subject: glsl: Make _mesa_print_ir() available from anything including ir.h.
X-Git-Tag: mesa-9.2.1~702
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=refs%2Fchanges%2F76%2F7076%2F1;p=platform%2Fupstream%2Fmesa.git

glsl: Make _mesa_print_ir() available from anything including ir.h.

No more forgetting to #include "ir_print_visitor.h" when doing temporary
debug code, or forgetting and leaving it in after removing your temporary
debug code.  Also, available from C code so you don't need to move the
caller to C++ just to call it (see also: ir_to_mesa.cpp).
