From: Kenneth Graunke Date: Wed, 20 Jan 2016 01:34:24 +0000 (-0800) Subject: nir: Let nir_opt_algebraic rules contain unsigned constants > INT_MAX. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b3cc10f3b24527e06da175cb8422f1e4f301cd87;p=mesa.git nir: Let nir_opt_algebraic rules contain unsigned constants > INT_MAX. struct.pack('i', val) interprets `val` as a signed integer, and dies if `val` > INT_MAX. For larger constants, we need to use 'I' which interprets it as an unsigned value. This patch makes us use 'I' for all values >= 0, and 'i' for negative values. This should work in all cases.
