Previously _LinkedShaders was a compact array of the linked shaders
for each shader stage. Now it is arranged such that each slot,
indexed by the MESA_SHADER_* defines, refers to a specific shader
stage. As a result, some slots will be NULL. This makes things a
little more complex in the linker, but it simplifies things in other
places.
As a side effect _NumLinkedShaders is removed.
NOTE: This may be a candidate for the 7.9 branch. If there are other
patches that get backported to 7.9 that use _LinkedShader, this patch
should be cherry picked also.

Also define it if #version 100 is encountered.

Make glsl include only main/core.h from core mesa.

Previously glcpp would silently abort if it couldn't fstat the file being
read, (so it would work with stdin redirected from a file, but would not
work with stdin as a tty). The stat was so that glcpp could allocate
a buffer for the file content in a single call.
We now use talloc_realloc instead, (even if the fstat is
possible). This is theoretically less efficient, but quite irrelevant,
(particularly because the standalone preprocessor is used only for
testing).
|
|
We recently added several tests that intentionally trigger
preprocessor errors. During valgrind-based testing, our test script
was noticing the non-zero return value from the preprocessor and
incorrectly flagging the valgrind-based test as failing.
To fix this, we make valgrind return an error code that is otherwise
unused by the preprocessor.
|
|
This error message was missing so that the program would simply
segfault if the provided filename could not be opened for some reason.
While we're at it, we add explicit support for a filename of "-" to
indicate input from stdin.
|
|
This fixes both "#line 0" and "#line XXX YYY" as described in the two
most recent commits.
|
|
The existing DECIMAL_INTEGER pattern is the correct thing to use when
looking for a C decimal integer, (that is, a digit-sequence not
starting with 0 which would instead be an octal integer).
But for #line, we really want to accept any digit sequence, (including
"0"), and always interpret it as a decimal constant. So we add a new
DIGITS pattern for this case.
This should fix the compilation failure noted in bug #28138
https://bugs.freedesktop.org/show_bug.cgi?id=28138
(Though the generated file will not be updated until the next commit.)

Previously, the YY_USER_ACTION was overwriting the yylloc->source value
in every action, (after that value had been carefully set by the handling
of the #line directive). Instead, we want to initialize it once in
YY_USER_INIT and then not touch it at all in YY_USER_ACTION.
|
|
This test exposes two current bugs:
1. The source number is not being correctly emitted in error
messages (instead, it's always 0).
2. A directive of "#line 0" is resulting in the following
parse error:
preprocessor error: Invalid tokens after #
|
|
The README file had grown a little bit stale. We've been using newer
versions of both the GLSL and C99 specifications, so list those. Also,
several of the documented known limitations have since been fixed, so
remove those.
|
|
This directive is already implemented nicely, but wasn't previously tested.
It will be convenient to use this directive in further tests that rely
on error messages, (such as ensuring that #line correctly sets the line
number in the error message).

After a recent change to glcpp-parse.y (adding "redefined macro" error).
|
|
Carefully avoiding printing any error when the new definition matches
the existing definition.
This fixes the recently-added 088-redefine-macro-legitimate.c and
089-redefine-macro-error.c tests as well as glsparsertest/preprocess1
in piglit.
|
|
The specification says that redefining a macro is an error, unless the
new definitions is identical to the old one, (identical replacement
lists but ignoring differing amounts of whitespace).
|
|
This is useful for debugging the preprocessor.
|
|
In commit 6be3a8b70af4ba4fa4d037d54ecf6d5f055edbc9, the #version directive
was fixed to stop generating a spurious newline. Here we simply update
the expected result for the single test which includes a #version directive.
|
|
The previous commit changed glcpp-lex.l so we commit the resulting
generated file here.
|
|
Matching the newline here meant having to do some redundant work here,
(incrementing line number, resetting column number, and returning a
NEWLINE token), that could otherwise simply be left to the existing rule
which matches a newline.
Worse, when the comment rule matches the newline as well, the parser
can lookahead and see a token for something that should actually be skipped.
For example, in a case like this:
#if 0 // comment here
fail
#else
win
#endif
Both fail and win appear in the output, (not that the condition is being
evaluated incorrectly---merely that one token after the comment's newline
was being lexed/parse regardless of the condition).
This commit fixes the above test case, (which is also remarkably similar
to 087-if-comments which now passes).
|
|
|
|
|
|
This was causing line numbering to be off by one. The newline comes
from the NEWLINE token at the end of the line; there's no need to
insert one.
|
|
This reverts commit a77a6bc008b3146c56431fa520a00e1f8dfa3938.

Also remove the --never-interactive command line option for the
preprocessor lexer. This was already done for main compiler lexer.

Makes the build happy on non-GCC platforms.

This was previously being appended to the output string *after* a copy
of the supposedly final string was made and handed to the caller. So
the diagnostic was never actually visible to the user.
We fix this by moving the check for an unterminated #if from
glcpp_parser_destroy to the calling function, preprocess.
This fixes the test case 083-unterminated-if.c.
|
|
Due to a recent change to glcpp-parse.y.
|
|
This is more clear than the previously-generated diagnostic which was
something confusing like "enexpected newline".
This change makse test 080-if-witout-expression.c now pass.
|
|
Rather than telling the user what to fix, the standard convention is to
describe what the detected problem is. With this change, test
081-elif-without-expression now passes.
|
|
Which are proving to be useful since some of these tests are not yet
acting as desired, (in particular, the unterminated if test is not
generating any diagnostic).
|
|
After a recent change to glcpp-lex.l
|
|
Error messages make more sense this way since the convention is for
the first line of a file to be numbered from 1, rather than 0.
|
|
This allows writing tests that verify diagnostics from the preprocessor.
|
|
|
|
The glcpp-test script was leaving around bogus *.valgrind-errors files if
a valgrind test was interrupted.
|
|
After a recent change to glcpp-parse.y
|
|
This adds a couple of test cases to expand our coverage of invalid #if and
being skipped, (either by being nested inside an #if/#elif that evaluates to
zero or by being after an #if/#elif that evaluates to non-zero).
