From b0ac07e3de8d9609fb0b1b7ec85b4149c4ee2c70 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Fri, 2 Jul 2010 17:02:42 -0700 Subject: [PATCH] ir_to_mesa: Fix up implementation of ir_unop_exp. OPCODE_EXP is not to ir_unop_exp what OPCODE_EX2 is to ir_unop_exp2. It's the weird VP approximation helper opcode. Just implement it with OPCODE_POW instead. Fixes glsl-fs-exp. --- src/mesa/shader/ir_to_mesa.cpp | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/src/mesa/shader/ir_to_mesa.cpp b/src/mesa/shader/ir_to_mesa.cpp index f8858af26d6..87d6f8452a2 100644 --- a/src/mesa/shader/ir_to_mesa.cpp +++ b/src/mesa/shader/ir_to_mesa.cpp @@ -625,7 +625,8 @@ ir_to_mesa_visitor::visit(ir_expression *ir) break; case ir_unop_exp: - ir_to_mesa_emit_scalar_op1(ir, OPCODE_EXP, result_dst, op[0]); + ir_to_mesa_emit_scalar_op2(ir, OPCODE_POW, result_dst, + src_reg_for_float(M_E), op[0]); break; case ir_unop_exp2: ir_to_mesa_emit_scalar_op1(ir, OPCODE_EX2, result_dst, op[0]); -- 2.30.2
