* gallivm: Lower TGSI_OPCODE_MUL to fmul by defaultTom Stellard2012-12-101-2/+3
| | | | | | | This fixes a number of crashes on r600g due to the fact that lp_build_mul assumes vector types when optimizing mul to bit shifts. This bug was uncovered by 0ad1fefd6951aa47ab58a41dc9ee73083cbcf85c

| | | | | | | | | | | | | | | | | Noticed would fail, we were doing two things wrong a) 1d arrays require the layers in height b) minifying the layers field. v2: don't change height code, fixup completely inside txq as suggested by Roland. v3: just add minify before texture array size v1: Reviewed-by: Jose Fonseca <[email protected]> Reviewed-by: Roland Scheidegger <[email protected]> Signed-off-by: Dave Airlie <[email protected]>

* draw: fix/improve dirty state validationBrian Paul2012-12-088-23/+68
| | | | | | | | | | | | | | | | | | | | This patch does two things: 1. Constant buffer state changes were broken (but happened to work by dumb luck). The problem is we weren't calling draw_do_flush() in draw_set_mapped_constant_buffer() when we changed that state. All the other draw_set_foo() functions were calling draw_do_flush() already. 2. Use a simpler state validation step when we're changing light-weight parameter state such as constant buffers, viewport dims or clip planes. There's no need to revalidate the whole pipeline when changing state like that. The new validation method is called bind_parameters() and is called instead of the prepare() method. A new DRAW_FLUSH_PARAMETER_CHANGE flag is used to signal these light-weight state changes. This results in a modest but measurable increase in FPS for many Mesa demos.

| | | | | | | | | | | | instances is found. This is a temporary hack.

* gallivm: drop border wrap clamping codeRoland Scheidegger2012-12-011-33/+16
| | | | | | | | | | | | | | | | | | | | | The border clamping code is unnecessary, since we don't care if a wrapped coord value is -1 or <-1 (same for length vs. >length), in either case the border handling code will mask out the offset and replace the texel value with the border color. Note that technically this is not entirely correct. Omitting clamping on the float coords means that flt->int conversion may result in undefined values for values of very large magnitude. However there's no reason we should honor this here since: a) we don't care for that for ordinary wrap modes in the aos code when converting coords and the problem is worse there (as we've got only effectively 24 instead of 32bits) b) at least in some cases the clamping was done already in int space hence doing nothing to fix that problem. c) with sse2 flt->int conversion with such values results in 0x80000000 which is just perfect (for clamp to border - not so much for the ordinary clamp to edge).

Seems to pass the relevant piglit tests both for sampling and rendering to (though some require version overrides).
