This adds three new pieces of state to the parser, (is_control_line,
newline_as_space, and paren_count), and a large amount of messy
code. I'd definitely like to see a cleaner solution for this.
With this fix, the "define-func-extra-newlines" now passes so we put
it back to test #26 where it was originally (lately it has been known
as test #55).
Also, we tweak test 25 slightly. Previously this test was ending a
file function-like macro name that was not actually a macro (not
followed by a left parenthesis). As is, this fix was making that test
fail because the text_line production expects to see a terminating
NEWLINE, but that NEWLINE is now getting turned into a SPACE here.
This seems unlikely to be a problem in the wild, (function macros
being used in a non-macro sense seems rare enough---but more than
likely they won't happen at the end of a file). Still, we document
this shortcoming in the README.

This is what I get for using a non-type-safe hash-table implementation.
|
|
Also changes the print visitor to not emit extraneous parenthesis.
|
|
Previously, the syntax was (array_ref <variable name> <index>), but the
subject is now a general rvalue (not a name). In particular, it might
be a (var_ref ...).
Also, remove "expected ... or (swiz)" from error messages; swiz is not
allowed inside a var_ref.
|
|
Array dereferences now point to variable dereferences instead of
pointing directly to variables. This necessitated some changes to the
way the variable is accessed when setting the maximum index array element.

Move the accept method for visitors from ir_dereference to the derived
classes.

Move the accept method for hierarchical visitors from ir_dereference
to the derived classes. This was mostly straight-forward, but I
suspect that ir_dead_code_local may be broken now.
|
|
Create separate subclasses of ir_dereference for variable, array, and
record dereferences. As a side effect, array and record dereferences
no longer point to ir_variable objects directly. Instead they each
point to an ir_dereference_variable object.
This is the first of several steps in the refactoring process. The
intention is that ir_dereference will eventually become an abstract
base class.

Use _mesa_meta_GenerateMipmap. It is Fast Enough(tm).

When generating or uploading a new (higher) mipmap level for an image,
we can need to allocate a miptree for a level greater than
texObj->MaxLevel.

This can happen when checking if a software fallback for a higher level
operation (such as GenerateMipmap) is needed.

It's now more separate from the rest of the driver and it can be disabled
by commenting out just 1 line. Well, I couldn't make the previous version
work with SW TCL reliably, that's the reason of this little rework.

This fixes piglit/draw-elements.

We could potentially do this on G45 as well, though the units are
different. On 965, the timestamp is tied to hclk, which would make
supporting it harder.

This is a workaround for Ironlake errata. The emit_mi_flush is used
for a few purposes:
1) Flushing write caches for RTT (including blit to texture)
2) Pipe fencing for sync objects
3) Spamming cache flushes to track down cache flush bugs
Spamming cache flushes seems less important than following the docs,
and we should probably do that with a different mechanism than the one
for render cache flushes.

To do this we have split the existing "HASH_IF expression" into two
productions:
First is HASH_IF pp_tokens which simply constructs a list of tokens.
Then, with that resulting token list, we first evaluate all DEFINED
operator tokens, then expand all macros, and finally start lexing from
the resulting token list. This brings us to the second production,
IF_EXPANDED expression
This final production works just like our previous "HASH_IF
expression", evaluating a constant integer expression.
The new test (54) added for this case now passes.

This was missed in commit f501230db3a94c9328b8e769d9c17b2c3792e19c.
Fixes SCons build.

Simply need to move the rule for IDENTIFIER to be after "defined" and
everything is happy.
With this change, tests 50 through 53 all pass now.
|
|
With this change, tests 41 through 49 all pass. (The defined operator
appears to be somehow broken so that test 50 doesn't pass yet.)
|
|
|
|
Which makes test 40 now pass.

The es1 and es2 dispath table initialization code is generated from the
API XML files and we can't easily share the dispatch table code setup.
Keep the _mesa_init_shader_dispatch() part of the patch, but roll back
the static-ization of shader entrypoints so es1 and es2 dispatch
initialization still works.
|
|
Now that we no longer have nested for loops with 'i' and 'j' we can
use the 'node' that we already have.
|
|
All the code referencing these was removed some time ago.
|
|
With this fix, tests 37 - 39 now pass.
|
|
None of these are fundamental---just a few things that haven't been
implemented yet.
|
|
Always better to use proper grammar in our grammar.
|
|
As required by the C99 specification of the preprocessor.
With this fix, tests 33 through 36 now pass.
|
|
This doesn't change any functionality here, but will allow us to make
future changes that were not possible with direct printing.
Specifically, we need to expand macros within macro arguments before
performing argument substitution. And *that* expansion cannot result
in immediate printing.
|
|
With this fix, test 32 no longer recurses infinitely, but now passes.
|
|
Supporting embedded newlines in a macro invocation is going to be
tricky with our current approach to lexing and parsing. Since this
isn't really an important feature for us, we can defer this until more
important things are resolved.
With this test out of the way, tests 27 through 31 are passing.

This trailing whitespace was coming from macro definitions and from
macro arguments. We fix this with a little extra state in the
token_list. It now remembers the last non-space token added, so that
these can be trimmed off just before printing the list.
With this fix test 23 now passes. Tests 24 and 25 are also passing,
but they probbably would ahve before this fix---just that they weren't
being run earlier.
