* swrast: remove MAX_WIDTH arrays in stencil codeBrian Paul2012-02-241-4/+11
| | | | Use some per-context temporary arrays instead.

* swrast: Fix unsigned promotion in pointer arithmeticChad Versace2012-01-231-3/+3
| | | | | | | | | | | | | | | | | | | | | | When rowstride was negatie, unsigned promotion caused a segfault here: 299│ if (rb->Format == MESA_FORMAT_S8) { 300│ const GLuint rowStride = rb->RowStride; 301│ for (i = 0; i < count; i++) { 302│ if (x[i] >= 0 && y[i] >= 0 && x[i] < w && y[i] < h) { 303├> stencil[i] = *(map + y[i] * rowStride + x[i]); 304│ } 305│ } 306│ } Fixes segfault in oglconform separatestencil-neu(NonPolygon.BothFacesBitmapCoreAPI), though test still fails. Note: This is a candidate for the stable branches.

* Track two sets of back-face stencil stateIan Romanick2009-01-231-2/+4
| | | | | | | | | | | | Track separate back-face stencil state for OpenGL 2.0 / GL_ATI_separate_stencil and GL_EXT_stencil_two_side. This allows all three to be enabled in a driver. One set of state is set via the 2.0 or ATI functions and is used when STENCIL_TEST_TWO_SIDE_EXT is disabled. The other is set by StencilFunc and StencilOp when the active stencil face is set to BACK. The GL_EXT_stencil_two_side spec has more details. http://opengl.org/registry/specs/EXT/stencil_two_side.txt
