| | | | | | | | | | | Aligning with a non-power-of-two number is a general task that can be used in various places. This commit is required for the next one. v2: add greater than 0 assertion (Anuj). convert the macro to a static inline function.

* mesa/macros: add power-of-two assertions for alignment macrosNanley Chery2015-08-261-2/+12
| | | | | | | | | | | | | ALIGN and ROUND_DOWN_TO both require that the alignment value passed into the macro be a power of two in the comments. Using software assertions verifies this to be the case. v2: use static inline functions instead of gcc-specific statement expressions (Brian). v3: fix indendation (Brian). v4: add greater than zero requirement (Anuj).

| | | | | | | | | | | I'm not sure what the true meaning of "The rounding mode may vary." is, but it is the case that the IROUND() path rounds differently than the other paths (and does it wrong, at that). Like _mesa_roundeven{f,}(), just add an use _mesa_lroundeven{f,}() that has known semantics. Reviewed-by: Roland Scheidegger <sroland@vmware.com>

* mesa: Avoid MSVC C6334 warning in /analyze mode.Jose Fonseca2015-03-251-0/+7
| | | | | | | | | | MSVC's implementation of signbit(x) uses sizeof(x) with expressions to dispatch to an internal function based on the argument's type (float, double, etc), but that raises a flag with MSVC's own static analyzer, and because this is an inline function in a header it causes substantial warning spam.

* mesa: use fi_type in vertex attribute codeMarius Predut2015-02-251-16/+18
| | | | | | | | | | | | | | | | | | | | | | | For 32-bit builds, floating point operations use x86 FPU registers, not SSE registers. If we're actually storing an integer in a float variable, the value might get modified when written to memory. This patch changes the VBO code to use the fi_type (float/int union) to store/copy vertex attributes. Also, this can improve performance on x86 because moving floats with integer registers instead of FP registers is faster. Neil Roberts review: - include changes on all places that are storing attribute values. - check with and without -O3 compiler flag. Brian Paul review: - use fi_type type instead gl_constant_value type - fix a bunch of nit-picks. - fix compiler warnings Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=82668 Signed-off-by: Marius Predut <marius.predut@intel.com> Reviewed-by: Brian Paul <brianp@vmware.com>

We removed OpenVMS support a while back, and this should alleviate the need to continue updating the this-platform-uses-IEEE list.

It looks like core Mesa has similar functions already, but none that allows an arbitrary number of fractional bits. The more generic version is probably useful to everyone. r600g apparently has an identical copy of the S_FIXED macro, but doesn't include this file.

* mesa: Fix bug in unclamped float to ubyte conversion.Manfred Ernst2013-06-121-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Problem: The IEEE float optimized version of UNCLAMPED_FLOAT_TO_UBYTE in macros.h computed incorrect results for inputs in the range 0x3f7f0000 (=0.99609375) to 0x3f7f7f80 (=0.99803924560546875) inclusive. 0x3f7f7f80 is the IEEE float value that results in 254.5 when multiplied by 255. With rounding mode "round to closest even integer", this is the largest float in the range 0.0-1.0 that is converted to 254 by the generic implementation of UNCLAMPED_FLOAT_TO_UBYTE. The IEEE float optimized version incorrectly defined the cut-off for mapping to 255 as 0x3f7f0000 (=255.0/256.0). The same bug was present in the function float_to_ubyte in u_math.h. Fix: The proposed fix replaces the incorrect cut-off value by 0x3f800000, which is the IEEE float representation of 1.0f. 0x3f7f7f81 (or any value in between) would also work, but 1.0f is probably cleaner. The patch does not regress piglit on llvmpipe and on i965 on sandy bridge.

* vbo: fix glVertexAttribI* functionsMarek Olšák2012-11-061-0/+39
| | | | | | | | | | | | | | | | | | | | | | The functions were broken, because they converted ints to floats. Now we can finally advertise OpenGL 3.0. ;) In this commit, the vbo module also tracks the type for each attrib in addition to the size. It can be one of FLOAT, INT, UNSIGNED_INT. The little ugliness is the vertex attribs are declared as floats even though there may be integer values. The code just copies integer values into them without any conversion. This implementation passes the glVertexAttribI piglit test which I am going to commit in piglit soon. The test covers vertex arrays, immediate mode and display lists.
