* mesa: Mark Identity as constIan Romanick2016-01-111-1/+1
| | | | | | | | | | | | | | | I was going to send this as review for dce1e1a8, but I missed that window. This saves 64 bytes of unshared data and prelaces it with 96 bytes shared text. My guess is that some of the calls to memcpy get optimized to something else. text data bss dec hex filename 7847613 220208 27432 8095253 7b8615 i965_dri.so before 7847709 220144 27432 8095285 7b8635 i965_dri.so after Signed-off-by: Ian Romanick <ian.d.romanick@intel.com> Reviewed-by: Ilia Mirkin <imirkin@alum.mit.edu> Cc: Brian Paul <brianp@vmware.com>

* mesa: Use floats for viewport bounds.Matt Turner2015-07-291-2/+2
| | | | | | | | | | | | | | | | | | ARB_viewport_array specifies that DEPTH_RANGE consists of double- precision parameters (corresponding commit d4dc35987), and a preparatory commit (6340e609a) added _mesa_get_viewport_xform() which returned double-precision scale[3] and translate[3] vectors, even though X, Y, Width, and Height were still floats. All users of _mesa_get_viewport_xform() immediately convert the double scale and translation vectors into floats (which were floats originally, but were converted to doubles in _mesa_get_viewport_xform(), sigh). i965 at least cannot consume doubles (see SF_CLIP_VIEWPORT). If we want to pass doubles to hardware, we should have a different function that does that. Acked-by: Mathias Froehlich <Mathias.Froehlich@web.de>

| | | | | | | | | | | So that it acts like ordinary free(). This lets us remove a bunch of if statements where the function is called. v2: - Avoiding compile error on MSVC and possible warnings on other compilers. - Added comment regards passing NULL pointer being safe.

I believe that was already the sensible interpretation, but spelling it out is probably better. More practically, it also prevents people from accidentally copy & pasting the license into a new file which says Brian is not liable when he isn't even one of the authors.

* mesa: loosen small matrix determinant checkBrian Paul2012-07-261-1/+1
| | | | | | | | | | | | | When computing a matrix inverse, if the determinant is too small we could hit a divide by zero. There's a check to prevent this (we basically give up on computing the inverse and return the identity matrix.) This patch loosens this test to fix a lighting bug reported by Lars Henning Wendt. v2: use abs(det) to handle negative values NOTE: This is a candidate for the 8.0 branch.
