Instead of using intr_name in lp_build_tgsi_action, this selects the names
with a switch statement in the emit function. This allows emitting
llvm.SI.sample for instructions without offsets and llvm.SI.image.sample.*.o
otherwise.
This depends on my LLVM changes.
When LLVM 3.5 is released, I'll switch all texture instructions to the new
intrinsics.
This happens when glGetMultisamplefv (or any other non-draw function) is
called, which doesn't invoke the VBO module to update _DrawArrays and
the pointer is invalid at that point.
However st/mesa still dereferences it to setup vertex buffers ==> crash.

Before, we were checking the level against view->u.tex.last_level but
level is not valid for buffers. Plus, the aliasing of the view->u.tex
view->u.buf members (a union) caused the level checking arithmetic to
be totally wrong. The net effect is we always returned early for
PIPE_BUFFER size queries.
This fixes the piglit "textureSize 140 fs samplerBuffer" test.

The lexer was insisting that there be at least one character after "#pragma"

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

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

name of the macro).
This commit fixes the following Khronos GLES3 conformance test:

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

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.

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

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.
