29ca7d2c94 st/dri: merge dri/drm and dri/sw backends
Move the driver_name to dri2/drisw and remove all the SPLIT_TAGETS
mayhem. In the next step we'll unify the dri and dri-swrast targets,
completing the gallium DRI megadriver.

v2: Remove leftover st/dri Makefiles from CONFIG_FILES. Spotted by

f6483aa694 targets/dri-swrast: convert to gallium megadrivers :)
Export the approapriate new symbol, and keep backwards compat
via the megadriver_stub helper library.

Our next step would be to unify dri/drm and dri/sw, leading to
a complete megadrivers solution, and having a single library
that provides dri across all targets.

0e12cd7954 glsl/glcpp: Don't choke on an empty pragma
The lexer was insisting that there be at least one character after "#pragma"
and before the end of the line. This caused an error for a line consisting
only of "#pragma" which volates at least the following sentence from the GLSL
ES Specification 3.00.4:

	The scope as well as the effect of the optimize and debug pragmas is
	implementation-dependent except that their use must not generate an
	error. [Page 12 (Page 28 of PDF)]

and likely the following sentence from that specification and also in
GLSLangSpec 4.30.6:

	If an implementation does not recognize the tokens following #pragma,
	then it will ignore that pragma.

Add a "make check" test to ensure no future regressions.

This change fixes at least part of the following Khronos GLES3 CTS test:

	preprocessor.pragmas.pragma_vertex

ec6222ef01 glsl/glcpp: Add short-circuiting for || and && in #if/#elif for OpenGL ES.
The GLSL ES Specification 3.00.4 says:

	#if, #ifdef, #ifndef, #else, #elif, and #endif are defined to operate
        as for C++ except for the following:
	...
	• Undefined identifiers not consumed by the defined operator do not
	  default to '0'. Use of such identifiers causes an error.

	[Page 11 (page 127 of the PDF file)]

as well as:

	The semantics of applying operators in the preprocessor match those
	standard in the C++ preprocessor with the following exceptions:

	• The 2nd operand in a logical and ('&&') operation is evaluated if
	  and only if the 1st operand evaluates to non-zero.

	• The 2nd operand in a logical or ('||') operation is evaluated if
	  and only if the 1st operand evaluates to zero.

	If an operand is not evaluated, the presence of undefined identifiers
	in the operand will not cause an error.

(Note that neither of these deviations from C++ preprocessor behavior apply to
non-ES GLSL, at least as of specfication version 4.30.6).

The first portion of this, (generating an error for an undefined macro in an
(short-circuiting to squelch errors), was not implemented previously, but is
implemented in this commit.

A test is added for "make check" to ensure this behavior.

Note: The change as implemented does make the error message a bit less
precise, (it just states that an undefined macro was encountered, but not the
name of the macro).

This commit fixes the following Khronos GLES3 conformance test:

	undefined_identifiers.valid_undefined_identifier_1_vertex
	undefined_identifiers.valid_undefined_identifier_1_fragment
	undefined_identifiers.valid_undefined_identifier_2_vertex
	undefined_identifiers.valid_undefined_identifier_2_fragment

9794f8f245 glsl/glcpp: Fix glcpp to properly lex entire "preprocessing numbers"
The preprocessor defines a notions of a "preprocessing number" that
starts with either a digit or a decimal point, and continues with zero
or more of digits, decimal points, identifier characters, or the sign
symbols, ('-' and '+').

Prior to this change, preprocessing numbers were lexed as some
combination of OTHER and IDENTIFIER tokens. This had the problem of
causing undesired macro expansion in some cases.

We add tests to ensure that the undesired macro expansion does not
happen in cases such as:

	#define e +1
	#define xyz -2

	int n = 1e;
	int p = 1xyz;

In either case these macro definitions have no effect after this
change, so that the numeric literals, (whether valid or not), will be
passed on as-is from the preprocessor to the compiler proper.

This fixes the following Khronos GLES3 CTS tests:

	preprocessor.basic.correct_phases_vertex
	preprocessor.basic.correct_phases_fragment

v2. Thanks to Anuj Phogat for improving the original regular expression,
(which accepted a '+' or '-', where these are only allowed after one of
[eEpP]. I also expanded the test to exercise this.

v3. Also fixed regular expression to require at least one digit at the
beginning (after an optional period). Otherwise, a string such as ".xyz" was
getting sucked up as a preprocessing number, (where obviously this should be a
field access). Again, I expanded the test to exercise this.

98c0e3c783 glsl/glcpp: Fix glcpp to catch garbage after #if 1 ... #else
Previously, a line such as:

	#else garbage

would flag an error if it followed "#if 0", but not if it followed "#if 1".

We fix this by setting a new bit of state (lexing_else) that allows the lexer
to defer switching to the <SKIP> start state until after the NEWLINE following
the #else directive.

A new test case is added for:

	#if 1
	#else garbage
	#endif

which was untested before, (and did not generate the desired error).

1d862a0b39 glsl/glcpp: Fixup glcpp tests for redefining a macro with whitespace changes.
Previously, the test suite was expecting the compiler to allow a redefintion
of a macro with whitespace added, but gcc is more strict and allows only for
changes in the amounts of whitespace, (but insists that whitespace exist or
not in exactly the same places).

See: https://gcc.gnu.org/onlinedocs/cpp/Undefining-and-Redefining-Macros.html:

 These definitions are effectively the same:

      #define FOUR (2 + 2)
      #define FOUR         (2    +    2)
      #define FOUR (2 /* two */ + 2)

 but these are not:

      #define FOUR (2 + 2)
      #define FOUR ( 2+2 )
      #define FOUR (2 * 2)
      #define FOUR(score,and,seven,years,ago) (2 + 2)

This change adjusts the existing "redefine-macro-legitimate" test to work with
the more strict understanding, and adds a new "redefine-whitespace" test to
verify that changes in the position of whitespace are flagged as errors.

099cbc1477 i965/fs: Track dependencies in instruction scheduling per reg offset.
Previously instruction scheduling tracked dependencies on a per-register
basis. This meant that there was an artificial dependency between
interpolation instructions writing into the same virtual register.

Instruction scheduling would insert a number of instructions between the
two instructions in this example, when they are actually independent.

   linterp vgrf8+0.0:F, hw_reg2:F, hw_reg3:F, hw_reg6:F
   linterp vgrf8+1.0:F, hw_reg2:F, hw_reg3:F, hw_reg6+16:F

This lead to cases where the first texture coordinate is interpolated at
the beginning of the shader, but the second is done immediately before
the texture operation that uses it as a source.

After this change, the artificial dependency is removed and the
interpolation instructions are scheduled together.

bbefb15e01 i965: Extend compute-to-mrf pass to understand blocks of MOVs
The current compute-to-mrf pass doesn't handle blocks of MOVs.  Shaders
that end with a texture fetch follwed by an fb write are left like this:

0x00000000: pln(8)          g6<1>F          g4<0,1,0>F      g2<8,8,1>F      { align1 WE_normal 1Q compacted };
0x00000008: pln(8)          g7<1>F          g4.4<0,1,0>F    g2<8,8,1>F      { align1 WE_normal 1Q compacted };
0x00000010: send(8)         g2<1>UW         g6<8,8,1>F
                            sampler (1, 0, 0, 1) mlen 2 rlen 4              { align1 WE_normal 1Q };
0x00000020: mov(8)          g113<1>F        g2<8,8,1>F                      { align1 WE_normal 1Q compacted };
0x00000028: mov(8)          g114<1>F        g3<8,8,1>F                      { align1 WE_normal 1Q compacted };
0x00000030: mov(8)          g115<1>F        g4<8,8,1>F                      { align1 WE_normal 1Q compacted };
0x00000038: mov(8)          g116<1>F        g5<8,8,1>F                      { align1 WE_normal 1Q compacted };
0x00000040: sendc(8)        null            g113<8,8,1>F
                            render ( RT write, 0, 4, 12) mlen 4 rlen 0      { align1 WE_normal 1Q EOT };

This patch lets compute-to-mrf recognize blocks of MOVs and match them to
instructions (typically SEND) that writes multiple registers.  With this,
the above shader becomes:

0x00000000: pln(8)          g6<1>F          g4<0,1,0>F      g2<8,8,1>F      { align1 WE_normal 1Q compacted };
0x00000008: pln(8)          g7<1>F          g4.4<0,1,0>F    g2<8,8,1>F      { align1 WE_normal 1Q compacted };
0x00000010: send(8)         g113<1>UW       g6<8,8,1>F
                            sampler (1, 0, 0, 1) mlen 2 rlen 4              { align1 WE_normal 1Q };
0x00000020: sendc(8)        null            g113<8,8,1>F
                            render ( RT write, 0, 20, 12) mlen 4 rlen 0     { align1 WE_normal 1Q EOT };

which is the bulk of the shader db results:

total instructions in shared programs: 987040 -> 986720 (-0.03%)
instructions in affected programs:     844 -> 524 (-37.91%)
GAINED:                                0
LOST:                                  0

The optimization also applies to MRT shaders that write the same
color value to multiple RTs, in which case we can eliminate four MOVs in
a similar fashion.  See fbo-drawbuffers2-blend in piglit for an example.

No measurable performance impact.  No piglit regressions.

8aa34dc9cb nvc0/ir: fill offset in properly for TXD
Apparently TXD wants its offset differently than TEX, accepting it in
the upper bits of the layer index. Unclear what happens when this is
combined with indirect sampler indexing.

114d46829d nvc0/ir: use manual TXD when offsets are involved
Something about how we're implementing offsets for TXD is wrong, just
flip to the generic quadop-based implementation in that case.

This is the minimal fix appropriate for backporting.
