* Remove the ATI_envmap_bumpmap extensionJason Ekstrand2014-06-302-32/+0
| | | | | | | | | | | As far as I can tell, the Intel mesa driver is the only driver in the world still supporting this legacy extension. If someone wants to do bump mapping, they can use shaders.

* glsl: Store info about geometry shaders that emit vertices to non-zero streams.Iago Toral Quiroga2014-06-301-0/+1
| | | | | | | | | | | On Intel hardware when a geometry shader outputs GL_POINTS primitives we only need to emit vertex control bits if it emits vertices to non-zero streams, so use a flag to track this. This flag will be set to TRUE when a geometry shader calls EmitStreamVertex() or EndStreamPrimitive() with a non-zero stream parameter in a later patch. Reviewed-by: Ian Romanick <[email protected]>

This patch keeps _mesa_shader_stage_to_program(), since its name is more consistent with other related functions.

* mesa: Use gl_shader::Stage instead of gl_shader::Type where possible.Paul Berry2014-01-082-14/+18
| | | | | | | | | | | | | | | | | | | | | This reduces confusion since gl_shader::Type is sometimes GL_SHADER_PROGRAM_MESA but is more frequently GL_SHADER_{VERTEX,GEOMETRY,FRAGMENT}. It also has the advantage that when switching on gl_shader::Stage, the compiler will alert if one of the possible enum types is unhandled. Finally, many functions in src/glsl (especially those dealing with linking) already use gl_shader_stage to represent pipeline stages; using gl_shader::Stage in those functions avoids the need for a conversion. Note: in the process I changed _mesa_write_shader_to_file() so that if it encounters an unexpected shader stage, it will use a file suffix of "????" rather than "geom".

This replaces the duplicate logic with an equivalent lowering pass that is used by all the back-ends. Note: on i965, there is a slight increase in instruction count. For example, a loop like this: for (int i = 0; i < 100; i++) { total += i; } would previously compile down to this (vec4) native code: mov(8) g4<1>.xD 0D mov(8) g8<1>.xD 0D loop: cmp.ge.f0(8) null g8<4;4,1>.xD 100D (+f0) break(8) add(8) g5<1>.xD g5<4;4,1>.xD g4<4;4,1>.xD add(8) g8<1>.xD g8<4;4,1>.xD 1D add(8) g4<1>.xD g4<4;4,1>.xD 1D while(8) loop After this patch, the "(+f0) break(8)" turns into: (+f0) if(8) break(8) endif(8) because the back-end isn't smart enough to recognize that "if (condition) break;" can be done using a conditional break instruction.
