From 5125165dde6ea6c3599810a92d6bcd4a5650adfd Mon Sep 17 00:00:00 2001 From: Erik Faye-Lund Date: Fri, 7 Feb 2014 13:45:11 +0100 Subject: gallium/tgsi: correct typo propagated from NV_vertex_program1_1 In the specification text of NV_vertex_program1_1, the upper limit of the RCC instruction is written as 1.884467e+19 in scientific notation, but as 0x5F800000 in binary. But the binary version translates to 1.84467e+19 rather than 1.884467e+19 in scientific notation. Since the lower-limit equals 2^-64 and the binary version equals 2^+64, let's assume the value in scientific notation is a typo and implement this using the value from the binary version instead.
