From 60f9b722ef80c499a94b4e5ab7304dcd739ea569 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Wed, 29 May 2013 23:27:45 -0700 Subject: Revert "i965: fix problem with constant out of bounds access (v2)" This reverts commit 98dfd59a0445666060c97b0dccaf0e9f030b547a. The patch was clearly not Piglit tested, as it caused at least 225 tests to start crashing with assertion failures. That was before my desktop tanked and the test run died completely. --- src/mesa/drivers/dri/i965/brw_fs.cpp | 12 +----------- 1 file changed, 1 insertion(+), 11 deletions(-) (limited to 'src/mesa/drivers/dri') diff --git a/src/mesa/drivers/dri/i965/brw_fs.cpp b/src/mesa/drivers/dri/i965/brw_fs.cpp index 9efdfc8e485..baaa25c1347 100644 --- a/src/mesa/drivers/dri/i965/brw_fs.cpp +++ b/src/mesa/drivers/dri/i965/brw_fs.cpp @@ -1504,13 +1504,7 @@ fs_visitor::remove_dead_constants() if (inst->src[i].file != UNIFORM) continue; - /* if we get a negative constant nr or one greater than we can - * handle, this can cause an overflow, we can't just refuse to - * build, so just go undefined and alias everyone to constant 0. - */ - if (constant_nr < 0 || constant_nr >= (int)c->prog_data.nr_params) { - constant_nr = 0; - } + assert(constant_nr < (int)c->prog_data.nr_params); /* For now, set this to non-negative.
