Subject: [ptxdist] [PATCH v2] libtheora: version bump 1.1.1 -> 1.2.0
Date: Mon, 12 Oct 2026 16:01:33 +0200 [thread overview]
Message-ID: <20261012140208.2958513-1-s.pueschel@pengutronix.de> (raw)
https://gitlab.xiph.org/xiph/theora/-/releases/v1.2.0
Adjusted the patches to apply correctly and use git ptx-patches to
generate them.
The LICENSE file checksum change is caused due to the removal of some
trailing whitespaces.
The floating point option has been removed as the critical path doesn't
use floating points anymore and to get some simpler code.
The release tarball missed some arm specific files. An additional patch
was added to include the files from the tagged git commit.
All other options have been reordered to match the output of the
configure_helper.py script and missing options have been added.
While most options are straight forward, asflags-probe seems to
dynamically adjust ASFLAGS to compile relevant asm instructions and then
decide at runtime (when they are supported) to use them. From the
configure.ac file of theora:
> gas will not assemble instructions unless the architecture explicitly
> supports it (unlike on x86).
> Try to speculatively add ASFLAGS to enable usage of these instructions
> at assembly time (actual support is detected at runtime).
> If the user has already specified -march or -mcpu flags, this may give
> some spurious warnings (use --disable-asflag-probe to avoid this if
> you don't want run-time support for instructions not available on the
> architecture you specified).

Change in v2:
- Include files missed in the tarball to avoid compilation errors on arm
platforms

+These files were missed in the release tarball. This has been already

+has happened since then.
+
+The files have been copied from the v1.2.0 git tag.

++; We could use the same strategy as the v filter below, but that would require
++; 40 instructions to load the data and transpose it into columns and another
++; 32 to write out the results at the end, plus the 52 instructions to do the
++; filtering itself.
++; This is slightly less, and less code, even assuming we could have shared the
++; 52 instructions in the middle with the other function.
++; It executes slightly fewer instructions than the ARMv6 approach David Conrad
++; proposed for FFmpeg, but not by much:
++; http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2010-February/083141.html
++; His is a lot less code, though, because it only does two rows at once instead
++; of four.

++; This uses the same strategy as the MMXEXT version for x86, except that UHADD8
++; computes (a+b>>1) instead of (a+b+1>>1) like PAVGB.
++; This works just as well, with the following procedure for computing the
++; filter value, f:
++; u = ~UHADD8(p1,~p2);
++; v = UHADD8(~p1,p2);
++; m = v-u;
++; a = m^UHADD8(m^p0,m^~p3);
++; f = UHADD8(UHADD8(a,u1),v1);
++; where f = 127+R, with R in [-127,128] defined as in the spec.
++; This is exactly the same amount of arithmetic as the version that uses PAVGB
++; as the basic operator.
++; It executes about 2/3 the number of instructions of David Conrad's approach,
++; but requires more code, because it does all eight columns at once, instead
++; of four at a time.
