* glsl: Allow texture2DProjLod and textureCubeLod in GL ESKalyan Kondapally2014-09-291-3/+3
| | | | | | | | | | According to GLES (i.e. 1.0 and above) spec textureCubeLod and texture2DProjLod are built in functions. We seem to disable support for these functions with GLES. This patch enables the support.

* glsl: Speed up constant folding for swizzles.Kenneth Graunke2014-09-121-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ir_rvalue::constant_expression_value() recursively walks down an IR tree, attempting to reduce it to a single constant value. This is useful when you want to know whether a variable has a constant expression value at all, and if so, what it is. The constant folding optimization pass attempts to replace rvalues with their constant expression value from the bottom up. That way, we can optimize subexpressions, and ideally stop as soon as we find a non-constant subexpression. In order to obtain the actual value of an expression, the optimization pass calls constant_expression_value(). But it should only do so if it knows the value can be combined into a constant. Otherwise, at each step of walking back up the tree, it will walk down the tree again, only to discover what it already knew: it isn't constant. We properly avoided this call for ir_expression nodes, but not for ir_swizzle nodes. This patch fixes that, drastically reducing compile times on certain shaders where tree grafting has given us huge expression trees. It also fixes SuperTuxKart. Thanks to Iago and Mike for help in tracking this down.

| | | | | | | | | | | | | | | According to GLSL-ES Spec(i.e. 1.0, 3.0), gl_Position value is undefined after the vertex processing stage if we don't write gl_Position. However, GLSL 1.10 Spec mentions that writing to gl_Position is mandatory. In case of GLSL-ES, it's not an error and atleast the linking should pass. Currently, Mesa throws an linker error in case we dont write to gl_position and Version is less then 140(GLSL) and 300(GLSL-ES). This patch changes it so that we don't report an error in case of GLSL-ES.

So we can use a simple [\r\n] to get the desired behavior while avoiding the flex bug.

| | | | | | | | | | | | | | | | | | | | | | | | There were two problems with the way this script used sed on OS X: 1. The OS X sed doesn't interpret "\r" in a replacement list as a carriage-return character, (instead it was inserting a literal 'r' character). We fix this by putting an actual ^M character into the source of the script, (rather than a two-character escape sequence hoping for sed to do the right thing). 2. When generating the test files with LF-CR ("\n\r") newlines, the OS X sed was adding an undesired final newline ("\n") at the end of the file. We avoid this by first using sed to add the ^M before the newlines, then using tr to swap the \r and \n characters. This way, sed never sees any lines ending with anything but \n, so it doesn't get confused and doesn't add any bogus extra newlines.
