* gbm: Log at least one dlerror() when we fail to open any drivers.Eric Anholt2014-07-301-0/+1
| | | | | | | | | | | | We don't want to log every single error (such as all the ones where the file wasn't even present in our list of search paths), but if you didn't find any driver, then seeing at least one error is useful (since the common case as a developer is a single DEFAULT_DRIVER_DIR or GBM_DRIVERS_PATH entry). v2: Rebase on swrast changes.

* gallivm: fix up out-of-bounds level when using conformant out-of-bound behaviorRoland Scheidegger2014-07-311-0/+1
| | | | | | | | | | | | | | | | | | | When using (d3d10) conformant out-of-bound behavior for texel fetching (currently always enabled) the level still needs to be set to a safe value even though the offset in the end won't get used because the level is used to look up the mip offset itself and the actual strides, which might otherwise crash. For simplicity, we'll use level 0 in this case (this ought to be safe, llvmpipe does not actually fill in level 0 information if first_level is larger, but some random strides / offsets shouldn't hurt as ultimately we always use offset 0 in this case). Fixes a crash in some in-house test where random huge levels appear in lp_build_fetch_texel() (the test actually uses level 0 always but if the fetching happens in a block with a execution mask random values may appear).

* dri: Add a new capabilities for drivers that can't share buffersGiovanni Campagna2014-07-306-11/+53
| | | | | | | | | | | | | | | | | | | The kms-dri swrast driver cannot share buffers using the GEM, so it must tell the loader to disable extensions relying on that, without disabling the image DRI extension altogether (which would prevent the loader from working at all). This requires a new gallium capability (which is queried on the pipe_screen and for swrast drivers it's forwarded to the winsys), and requires a new version of the DRI image extension. [Emil Velikov] - Rebased on top of gallium-dri megadrivers. - Drop PIPE_CAP_BUFFER_SHARE and sw_winsys::get_param hook. The can_share_buffer cap is set at InitScreen. We use a different InitScreen (and thus value for the cap) function for kms_dri, due to deeper differences originating from dri megadrivers. Signed-off-by: Emil Velikov <[email protected]>

* glsl: Add flex options to eliminate the default ruleCarl Worth2014-07-291-10/+1
| | | | | | | | | | | | | | | | | | | | We've had bugs in the past where we have been inadvertently matching the default rule. Just as we did in the pre-processor in the previous commit, we can use: %option warn nodefault in the compiler to instruct flex to not generate the default rule, and further to warn if our set of rules could let any characters go unmatched. With this warning active, flex actually warns that the catch-all rule we recently added to the compiler could never be matched. Since that is all safely determined at compile time now, we can safely drop this run-time compiler error message, (as we do in this commit).

* glsl/glcpp: Add flex options to eliminate the default rule.Carl Worth2014-07-291-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | We've had multiple bugs in the past where we have been inadvertently matching the default rule, (which we never want to do). We recently added a catch-all rule to avoid this, (and made this rule robust for future start conditions). Kristian pointed out that flex allows us to go one step better. This syntax: %option warn nodefault instructs flex to not generate the default rule at all. Further, flex will generate a warning at compile time if the set of rules we provide are inadequate, (such that it would be possible for the default rule to be matched). With this warning in place, I found that the catch-all rule was in fact missing something. The catch-all rule uses a pattern of "." which doesn't match newlines. So here we extend the newline-matching rule to all start conditions. That is enough to convince flex that it really doesn't need any default rule.

* glsl/glcpp: Add a catch-all rule for unexpected characters.Carl Worth2014-07-291-0/+13
| | | | | | | | | | | | | | | | | | In some of the recent glcpp bug-fixing, we found that glcpp was emitting unrecognized characters from the input source file to stdout, and dropping them from the source passed onto the compiler proper. This was obviously confusing, and totally undesired. The bogus behavior comes from an implicit default rule in flex, which is that any unmatched character is implicitly matched and printed to stdout. To avoid this implicit matching and printing, here we add an explicit catch-all rule. If this rule ever matches it prints an internal compiler error. The correct response for any such error is fixing glcpp to handle the unexpected character in the correct way. Reviewed-by: Jordan Justen <[email protected]>
* glsl/glcpp: Treat carriage return as equivalent to line feed.Carl Worth2014-07-291-9/+8
| | | | | | | | | | | | | | | | | | | Previously, the '\r' character was not explicitly matched by any lexer rule. This means that glcpp would have been using the default flex rule to match '\r' characters, (where they would have been printed to stdout rather than actually correctly handled). With this commit, we treat '\r' as equivalent to '\n'. This is clearly an improvement the bogus printing to stdout. The resulting behavior is compliant with the GLSL specification for any source file that uses exclusively '\r' or '\n' to separate lines. For shaders that use a multiple-character line separator, (such as "\r\n"), glcpp won't be precisely compliant with the specification, (treating these as two newline characters rather than one), but this should not introduce any semantic changes to the shader programs.

| | | | | | | | | | | | | | | | | | | This test is written to exercise a bug which I recently wrote, (but fortunately caught and fixed before ever committing it). For the curious: The bug happened when the NEWLINE_CATCHUP code didn't actually return the NEWLINE token (due to the skipping). This resulted in the lexer continuing on through all the subsequent rules while still in the NEWLINE_CATCHUP start condition, (which then triggered the internal-compiler-error catch-all rule). What is intended is for the return of the NEWLINE token to start a new iteration of the lexer loop, at which time the NEWLINE_CATCHUP-handling code will reset from the <NEWLINE_CATCHUP> to the <INITIAL> start condition.

| | | | | | | | | | | | At one point while rewriting the lexing rule for pre-processing numbers, I made it a bit too aggressive and within a replacement list sucked up a parameter name that appeared immediately after a period.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | These operators aren't defined for preprocessor expressions, so we never implemented them. This led them to be misinterpreted as strings of unary '+' or '-' operators. In fact, what is actually desired is to generate an error if these operators appear in any preprocessor condition. So this commit looks like it is strictly adding support for these operators. And it is supporting them as far as passing them through to the subsequent compiler, (which was already happening anyway). What's less apparent in the commit is that with these tokens now being lexed, but with no change to the grammar for preprocessor expressions, these operators will now trigger errors there. A new "make check" test is added to verify the desired behavior.

* glsl/glcpp: Correctly parse directives with intervening commentsCarl Worth2014-07-2916-110/+242

Our implementation does not use an actual separate phase for comment removal, so some extra care is necessary to correctly parse this. What we want is for '#' to introduce a directive iff it is the first token on a line, (ignoring whitespace and comments). Previously, we had a lexical rule that worked only for whitespace (not comments) with the following regular expression to find a directive-introducing '#' at the beginning of a line: HASH ^{HSPACE}*#{HSPACE}* In this commit, we switch to instead use a simple literal match of '#' to return a HASH_TOKEN token and add a new <HASH> start condition for whenever the HASH_TOKEN is the first non-space token of a line. This requires the addition of the new bit of state: first_non_space_token_this_line. This approach has a couple of implications on the glcpp parser: 1. The parser now sees two separate tokens, (such as HASH_TOKEN and HASH_DEFINE) where it previously saw one token (HASH_DEFINE) for the sequence "#define". This is a straightforward change throughout the grammar. 2. The parser may now see a SPACE token before the HASH_TOKEN token of a directive. Previously the lexical regular expression for {HASH} would eat up the space and there would be no SPACE token. This second implication is a bit of a nuisance for the parser. It causes a SPACE token to appear in a production of the grammar with the following two definitions of a control_line: control_line SPACE control_line This is really ugly, since normally a space would simply be a token separator, so it wouldn't appear in the tokens of a production. This leads to a further problem with interleaved spaces and comments: /* ... */ /* ... */ #define /* ..*/ For this, we must not return several consecutive SPACE tokens, or else we would need an arbitrary number of new productions: SPACE SPACE control_line SPACE SPACE SPACE control_line ad nauseam To avoid this problem, in this commit we also change the lexer to emit only a single SPACE token for any series of consecutive spaces, (whether from actual whitespace or comments). For this compression, we add a new bit of parser state: last_token_was_space. And we also update the expected results of all necessary test cases for the new compression of space tokens. Fortunately, the compression of spaces should not lead to any semantic changes in terms of what the eventual GLSL compiler sees. So there's a lot happening in this commit, (particularly for such a tiny feature). But fortunately, the lexer itself is looking cleaner than ever. The only ugly bit is all the state updating, but it is at least isolated to a single shared function. Of course, a new "make check" test is added for the new feature, (directives with comments and whitespace interleaved in many combinations).

Both start conditions and token types are, of course, in the same default C namespace, so a start condition and a token type with the same name will collide.

| | | | | | | | | | | | | | | | | | | | | This commit does not cause any behavioral change for any valid program. Prior to entering the <DEFINE> start condition, the only valid start condition is <INITIAL>, so whether pushing/popping <DEFINE> onto the stack or explicit returning to <INITIAL> is equivalent. The reason for this change is that we are planning to soon add a start condition for <HASH> with the following semantics: <HASH>: We just saw a directive-introducing '#' <DEFINE>: We just saw "#define" starting a directive With these two start conditions in place, the only correct behavior is to leave <DEFINE> by returning to <INITIAL>.

* glsl/glcpp: Stop using a lexer start condition (<SKIP>) for token skipping.Carl Worth2014-07-293-63/+99
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here, "skipping" refers to the lexer not emitting any tokens for portions of the file within an #if condition (or similar) that evaluates to false. Previously, the lexer had a special <SKIP> start condition used to control this skipping. This start condition was not handled like a normal start condition. Instead, there was a particularly ugly block of code set to be included at the top of the generated lexing loop that would change from <INITIAL> to <SKIP> or from <SKIP> to <INITIAL> depending on various pieces of parser state, (such as parser->skip_state and parser->lexing_directive). Not only was that an ugly approach, but the <SKIP> start condition was complicating several glcpp bug fixes I attempted recently that want to use start conditions for other purposes, (such as a new <HASH> start condition). The recently added RETURN_TOKEN macro gives us a convenient way to implement skipping without using a lexer start condition. Now, at the top of the generated lexer, we examine all the necessary parser state and set a new parser->skipping bit. Then, in RETURN_TOKEN, we examine parser->skipping to determine whether to actually emit the token or not. Besides this, there are only a couple of other places where we need to examine the skipping bit (other than when returning a token): * To avoid emitting an error for #error if skipped. * To avoid entering the <DEFINE> start condition for a #define that is skipped. With all of this in place in the present commit, there are hopefully no behavioral changes with this patch, ("make check" still passes all of the glcpp tests at least).

| | | | | | | | | | | | | | | | | | | | The glcpp parser is line-based, so it needs to see a NEWLINE token at the end of each line. This causes a trick for files that end without a final newline. Previously, the lexer for glcpp punted in this case by unconditionally returning a NEWLINE token at end-of-file, (causing most files to have an extra blank line at the end). Here, we refine this by lexing end-of-file as a NEWLINE token only if the immediately preceding token was not a NEWLINE token. The patch is a minor change that only looks huge for two reasons: 1. Almost all glcpp test result ".expected" files are updated to drop the extra newline. 2. All return statements from the lexer are adjusted to use a new RETURN_TOKEN macro that tracks the last-token-was-a-newline state. Reviewed-by: Jordan Justen <[email protected]>

Additionally, the <EOF> action was restricted only to the <INITIAL> state so it would fail to get invoked if the EOF was encountered in the <COMMENT> or the <DEFINE> case. Neither of these was a bug, per se, since EOF in either of these cases is an error anyway, (either "unterminated comment" or "missing macro name for #define").

I don't think either case could have caused any actual bug. (In the first case, the pattern matched right up to the next newline, so the NEWLINE_CATCHUP code was just about to be called.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, if the preprocessor encountered a #define with a non-identifier, such as: #define 123 456 The lexer had no explicit rules to match non-identifiers in the <DEFINE> start state. Because of this, flex's default rule was being invoked, (printing characters to stdout), and all text was being discarded by the compiler until the next identifier. As one can imagine, this led to all sorts of interesting and surprising results. Fix this by adding an explicit rule complementing the existing identifier-based rules that should catch all non-identifiers after #define and reliably give a well-formatted error message. A new test is added to "make check" to ensure this bug stays fixed. This commit also fixes the following Khronos GLES3 CTS test: define_non_identifier_vertex (The "fragment" variant was passing earlier only because the preprocessor was behaving so randomly and causing the compilation to fail.

Here we fix the bug by also setting the space_tokens bit whenever we lex a newline in the standard start conditions.

* st/wgl: Clamp wglChoosePixelFormatARB's output nNumFormats to nMaxFormats.José Fonseca2014-07-291-2/+4
| | | | | | | | | | | | | | While running https://github.com/nvMcJohn/apitest with apitrace I noticed that Mesa was producing bogus results: wglChoosePixelFormatARB(hdc, piAttribIList = {...}, pfAttribFList = &0, nMaxFormats = 1, piFormats = {19, 65576, 37, 198656, 131075, 0, 402653184, 0, 0, 0, 0, -573575710}, nNumFormats = &12) = TRUE However https://www.opengl.org/registry/specs/ARB/wgl_pixel_format.txt states <nNumFormats> returns the number of matching formats. The returned value is guaranteed to be no larger than <nMaxFormats>. Cc: "10.2" <[email protected]> Reviewed-by: Brian Paul <[email protected]>

* r600g,radeonsi: switch all occurences of array_size to util_max_layerMarek Olšák2014-07-283-6/+10
| | | | | | | | | | | | | | | | | | This fixes 3D texture support in all these cases, because array_size is 1 with 3D textures and depth0 actually contains the "array size". util_max_layer is universal and returns the last layer index for any texture target. A lot of the cases below can't actually be hit with 3D textures, but let's be consistent. This fixes a failure in: piglit layered-rendering/clear-color-all-types 3d single_level for r600g and radeonsi, which was caused by an incorrect CMASK size calculation.
