Re-added calls to `stbte__hittest()`, fixed some compiler errors.
Also fixed some GCC warnings about unused variables when
STBTE__COLORPICKER and STBTE_ALLOW_LINK is not defined.
Confirmed from the OpenType spec that there's nothing missing
here. (These were just annotations listing the total sizes of
the tables, but this is not used for anything here.)
Fixes issue #704.
As per MS's own docs, should ignore the r/g/b bitmasks in the
header unless BI_BITFIELDS compression is selected. Factor out
setting the default masks since that now exists in two branches.
Add some more checking for unsupported compression formats and
illegal bpp/compression combinations while I'm at it.
Fixes issue #783.
As per issue 634, Stua "will be deleted from stb.h" soonish. That
was 3 years ago, which should be plenty of warning, and the
language has been de-facto orphaned and undocumented for a
good while longer than that.
Fixes issue #634.
Released Clang 12 generates bad code for the original loop in here.
While this is a compiler bug plain and simple, we still have to deal
with it.
This is related to the SLP vectorizer, and in particular the two
reverse subtracts in the butterflies for the second half to avoid
unary negates.
Use the more regular dataflow that has the unary negates in it
(we can at least fold one of them into a constant, namely for A2)
and introduce a few temporaries that also make alias analysis (and
possible block-level vectorization) a whole let easier while I'm at
it.
This fixes the codegen issues on Clang 12, which now produces a
working decoder, and I expect the single unary negate that we
actually gain per iteration of this loop is not a significant
perf concern. (There are bigger fish to fry here regardless.)
Fixes issue #1152.
Some parameters do not get used, or only when certain config
defines are set. Explicitly mark them as unused to make compilers
happy.
Fixes issue #396.
This is definitely unnecessary, or at least I can't find anything
in the Vorbis spec that would indicate anything special happening
here.
Fixes issue #816.
When start_decoder() fails it may already have allocated memory
for .vendor and/or .comment_list. Call vorbis_deinit() to free
any allocated memory.
Fixes issue #1051.
Not an actual bug, it just looked wonky, but this code runs
with code lengths that are verified to be in range (<32) by
the length-reading code. Anyway.
Fixes issue #901.
Put the formats that start with a clear magic number first,
the dodgy ones that don't have much of a distinctive header
should be tested for later after we've ruled out the clearer
ones.
Fixes issue #787, hopefully. (Never got a clean repro.)
It's implementation-specified behavior. Writing this code and then
relying on compiler strength reduction to turn it back into shifts
feels extremely silly but it is what it is.
Fixes issue #1097.
