From 05659223bf02c8bac0463fe1e7a9364ef5677b75 Mon Sep 17 00:00:00 2001 From: Thiago Macieira Date: Mon, 17 Dec 2012 22:24:55 -0800 Subject: Rename qt_mips_asm_dsp.h to a "_p.h" header It mustn't be installed and it mustn't be available in the master include. It's an assembler header anyway. Also, take the opportunity to add the "We mean it".
