According to the GLSL 4.30 specification, this is a compile time error.
Earlier specifications don't specify a behavior, but since 0 and 1 are

Eric Anholt 2ea3ab14f2 glsl: Add a "ubo_load" expression type for fetches from UBOs.
Drivers will probably want to be able to take UBO references in a
shader like:

        uniform ubo1 {
                float a;
                float b;
                float c;
                float d;
        }

        void main() {
             gl_FragColor = vec4(a, b, c, d);
        }

and generate a single aligned vec4 load out of the UBO.  For intel,
this involves recognizing the shared offset of the aligned loads and
CSEing them out.  Obviously that involves breaking things down to
loads from an offset from a particular UBO first.  Thus, the driver
doesn't want to see

	variable_ref(ir_variable("a")),

and even more so does it not want to see

	array_ref(record_ref(variable_ref(ir_variable("a")),
          "field1"), variable_ref(ir_variable("i"))).

where a.field1[i] is a row_major matrix.

Instead, we're going to make a lowering pass to break UBO references
down to expressions that are obvious to codegen, and amenable to
merging through CSE.

v2: Fix some partial thoughts in the ir_binop comment (review by Kenneth)

Kenneth Graunke 3a90dc22d1 glsl: Refactor #version validation to be more future-proof.
The previous implementation required a flag in _mesa_glsl_parse_state
and line of code to initialize it for every version of the shading
language we intend to support.  As we look to add 150, 330, 400, 410,
420, and beyond, this gets rather unwieldy.

This patch retains the switch statement (to reject, say, #version 111),
but removes all the bits.  Code to check for ctx->API == API_OPENGL_CORE
could easily be added to the 110 and 120 cases to reject those.

    presence of the new API_OPENGL_CORE enumeration.

Paul Berry 0f1f2ff8db mesa: Set gl_fragment_program::UsesKill in do_set_program_inouts.
Previously, the code for setting this flag for GLSL programs was
duplicated in three places: brw_link_shader(), glsl_to_tgsi_visitor,
and ir_to_mesa_visitor.  In addition to the unnecessary duplication,
there was a performance problem on i965: brw_link_shader() set the
flag before doing its final round of optimizations, which meant that
if the optimizations managed to eliminate all the discard operations,
the flag would still be set, resulting (at least in theory) in slower
performance.

This patch consolidates all of the code that sets UsesKill for GLSL
programs into do_set_program_inouts(), which already is doing a
similar job for UsesDFdy, and which occurs after i965's final round of
optimizations.

Non-GLSL programs (ARB programs and the state tracker's glBitmap
program) are unaffected.
