From 8ec0b8187ea695353c75eed7314e86344df60e5a Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Thu, 22 Jul 2010 13:52:41 -0700 Subject: glsl2: When inlining, don't clone and assign sampler arguments. Instead, just use the incoming sampler param. Fixes many texture-using piglit tests since the linker rework. --- src/glsl/ir_function_inlining.cpp | 26 ++++++++++++++++++-------- 1 file changed, 18 insertions(+), 8 deletions(-) (limited to 'src/glsl/ir_function_inlining.cpp') diff --git a/src/glsl/ir_function_inlining.cpp b/src/glsl/ir_function_inlining.cpp index c391f12d88..b143190ff6 100644 --- a/src/glsl/ir_function_inlining.cpp +++ b/src/glsl/ir_function_inlining.cpp @@ -133,17 +133,27 @@ ir_call::generate_inline(ir_instruction *next_ir) exec_list_iterator sig_param_iter = this->callee->parameters.iterator(); exec_list_iterator param_iter = this->actual_parameters.iterator(); for (i = 0; i < num_parameters; i++) { - const ir_variable *const sig_param = (ir_variable *) sig_param_iter.get(); + ir_variable *sig_param = (ir_variable *) sig_param_iter.get(); ir_rvalue *param = (ir_rvalue *) param_iter.get(); /* Generate a new variable for the parameter. */ - parameters[i] = sig_param->clone(ht); - parameters[i]->mode = ir_var_auto; - next_ir->insert_before(parameters[i]); + if (sig_param->type->base_type == GLSL_TYPE_SAMPLER) { + /* For samplers, we want the inlined sampler references + * referencing the passed in sampler variable, since that + * will have the location information, which an assignment of + * a sampler wouldn't. + */ + parameters[i] = NULL; + hash_table_insert(ht, param->variable_referenced(), sig_param); + } else { + parameters[i] = sig_param->clone(ht); + parameters[i]->mode = ir_var_auto; + next_ir->insert_before(parameters[i]); + } /* Move the actual param into our param variable if it's an 'in' type. */ - if (sig_param->mode == ir_var_in || - sig_param->mode == ir_var_inout) { + if (parameters[i] && (sig_param->mode == ir_var_in || + sig_param->mode == ir_var_inout)) { ir_assignment *assign; assign = new(ctx) ir_assignment(new(ctx) ir_dereference_variable(parameters[i]), @@ -175,8 +185,8 @@ ir_call::generate_inline(ir_instruction *next_ir) const ir_variable *const sig_param = (ir_variable *) sig_param_iter.get(); /* Move our param variable into the actual param if it's an 'out' type. */ - if (sig_param->mode == ir_var_out || - sig_param->mode == ir_var_inout) { + if (parameters[i] && (sig_param->mode == ir_var_out || + sig_param->mode == ir_var_inout)) { ir_assignment *assign; assign = new(ctx) ir_assignment(param->clone(NULL)->as_rvalue(), -- cgit v1.2.3
