From 45df4bad9fc0379f05197bee10c03fd351f24094 Mon Sep 17 00:00:00 2001 From: Vinson Lee Date: Thu, 4 Mar 2010 17:40:36 -0800 Subject: [PATCH] Revert "mesa: Remove pointless comparison of unsigned integer with a negative constant." This reverts commit a05fdbcb719ac64e6be842372813f0f4ca2f4f93. Removing the comparison is wrong. The comparison with -1 should be changed to another value (probably PROGRAM_UNDEFINED) along with another change in the shader assembler.
