The non-llvm path made sure that both clip and pre_clip_pos point to the data
output by position, not clipvertex, if user based clipping is disabled.
However, the llvm path did not, which apparently led to failures if
gl_ClipVertex was written but user plane clipping not enabled (bug 80183).
Why I have no idea really, but just make it match the non-llvm behavior...

The distinction between system values and ordinary inputs is not very
obvious in gallium - further fueled by the fact that they use the same
semantic names.
Still, if there's any value which imho really is a system value, it's the
primitive id input into the gs (while earlier (tessleation) stages could read
it, it is _always_ generated by the system). For some odd reason though (which
I'd classify as a bug but seems too complicated to fix) the glsl compiler in
mesa treats this as an ordinary varying, and everything else after that
(including the state tracker and other drivers) just go along with that.
But input fetching in gs for llvm based draw was definitely limited to the
ordinary (2-dimensional) inputs so only worked with other state trackers,
the code was also additionally relying on tgsi_scan_shader filling
uses_primid correctly which did not happen neither (would set it only for
all stages if it was a system value, but only set it for the fragment shader
if it was an input value).

Previously, we explicitly set the execution size to BRW_EXECUTE_8 and
disabled compression for loop instructions. I can't imagine how this
could be correct in SIMD16 mode.
Looking at the history, it appears that this code has used BRW_EXECUTE_8
since 2007, when we had a SIMD8 backend that supported control flow and
a separate SIMD16 backend that didn't. Presumably, when we added SIMD16
support for shaders with control flow, we simply neglected to update it.
Note that Gen4-5 don't support SIMD16 on shaders with control flow.
This might be a candidate for stable, but would need to be rewritten

Here is some additional stress testing of nested macros where the expansion
of macros involves commas, (and whether those commas are interpreted as
argument separators or not in subsequent function-like macro calls).
Credit to the GCC documentation that directed my attention toward this issue:
https://gcc.gnu.org/onlinedocs/gcc-3.2/cpp/Argument-Prescan.html
Fixing the bug required only removing code from glcpp. When first testing the
details of expansions involving commas, I had come to the mistaken conclusion
that an expanded comma should never be treated as an argument separator, (so
had introduced the rather ugly COMMA_FINAL token to represent this).
In fact, an expanded comma should be treated as a separator, (as tested here),
and this treatment can be avoided by judicious use of parentheses (as also
tested here).
With this simple removal of the COMMA_FINAL token, the behavior of glcpp
matches that of gcc's preprocessor for all of these hairy cases.

Beyond just listing this in the TESTS variable in Makefile.am, only minor

The (optional) test-specific command-line arguments to be passed to glcpp are
embedded within the source files of some tests, and glcpp-test uses grep to
extract them.
Of course, grep is line-based and looks for the native line-separator to
determine line boundaries. So, for files using non-native line separators,
grep was getting quite confused and passing bogus arguments to glcpp.
Fix this by canonical-izing the line separators in the source file prior to
using grep.
With this commit, the glcpp-test-cr-lf tests pass entirely:

Sometimes the newline separator is a single character, and sometimes it is two
characters. Before we can fold away and line-continuation backslashes, we
identify the flavor of line separator that is in use.
With this identified, we then correctly search for backslashes followed
immediately by the first character of the line separator.
Also, when re-inserting newlines to replace collapsed newlines, we carefully
insert newlines of the same flavor.

The GLSL specification says that either carriage-return, line-feed, or both
together can be used to terminate lines. Further, it says that when used
together, the pair of terminators shall be interpreted as a single line.
This final requirement has not been respected by glcpp up until now, (it has
been emitting two newlines for every CR+LF pair).
Here, we fix the lexer by using a regular expression for NEWLINE that eats
up both "\r\n" (or even "\n\r") if possible before also considering a single
'\n' or a single '\r' as a line terminator.
Before this commit, the test results are as follows:
\r: 135/143 tests pass
\r\n: 4/143 tests pass
\n\r: 4/143 tests pass
After this commit, the test results are as follows:
\r: 135/143 tests pass
\r\n: 140/143 tests pass
\n\r: 139/143 tests pass

The GLSL specification has a very broad definition of what is a
newline. Namely, it can be the carriage-return character, '\r', the newline
character, '\n', or any combination of the two, (though in combination, the
two are treated as a single newline).
Here, we add a new test-runner, glcpp-test-cr-lf, that, for each possible
line-termination combination, runs through the existing test suite with all
source files modified to use those line-termination characters. Instead of
using the .expected files for this, this script assumes that the regular test
suite has been run already and expects the output to match the .out
files. This avoids getting 4 test failures for any one bug, and instead will
hopefully only report bugs actually related to the line-termination
characters.
The new testing is not yet integrated into "make check". For that, some
munging of the testdir option will be necessary, (to support "make check" with
out-of-tree builds). For now, the scripts can just be run directly by hand.

Prior to this commit, the following snippet would trigger an error in glcpp:
#define FOO defined BAR
#if FOO
#endif
The problem was that support for the "defined" operator was implemented within
the grammar, (where the parser was parsing the tokens of the condition
itself). But what is required is to interpret the "defined" operator that
results after macro expansion is performed.
I could not find any fix for this case by modifying the grammar alone. The
difficulty is that outside of the grammar we already have a recursive function
that performs macro expansion (_glcpp_parser_expand_token_list) and that
function itself must be augmented to be made aware of the semantics of the
"defined" operator.
The reason we can't simply handle "defined" outside of the recursive expansion
function is that not only must we scan for any "defined" operators in the
original condition (before any macro expansion occurs); but at each level of
the recursive expansion, we must again scan the list of tokens resulting from
expansion and handle "defined" before entering the next level of recursion to
further expand macros.
And of course, all of this is context dependent. The evaluation of "defined"
operators must only happen when we are handling preprocessor conditionals,
(#if and #elif) and not when performing any other expansion, (such as in the
main body).
To implement this, we add a new "mode" parameter to all of the expansion
functions to specify whether resulting DEFINED tokens should be evaluated or
ignored.
One side benefit of this change is that an ugly wart in the grammar is
removed. We previously had "conditional_token" and "conditional_tokens"
productions that were basically copies of "pp_token" and "pp_tokens" but with
added productions for the various forms of DEFINED operators. With the new
code here, those ugly copy-and-paste productions are eliminated from the
grammar.
A new "make check" test is added to stress-test the code here.

Previously, glcpp would emit an error like this if <EOF> happened to occur
immediately after the "#define", but in general would just get confused,
(leading to un-helpful error messages).
To fix things to generate a clean error message, we do a few things:
1. Don't require horizontal whitespace immediately after #define
2. Add a production for the error case, (DEFINE_TOKEN followed
immediately by a NEWLINE token).
3. Make the lexer reset to the <INITIAL> state after every NEWLINE.
This 3rd point prevents the lexer from getting so confused and generating
further spurious errors in the file because it was stuck in the <DEFINE> start
condition.
We also drop the similar error message from the <EOF> rule since the
newly-added rule will have already printed the error message.
