* Fri Mar 18 2016 Kevin Kofler <Kevin@tigcc.ticalc.org> - 5.6.0-3
- Build with CONFIG+="webcore_debug v8base_debug"
- Force -fno-delete-null-pointer-checks through CXXFLAGS, Qt flags not used here
This reverts commit 65fd4d09a1.
The tarball is not redistributable, the EVR bump was done wrong (goes
backwards), and the package does not even build (because the uploaded
tarball does not have "-clean" in the file name), so there is absolutely
nothing worth keeping in that commit.
Note that almost all the patch size increase is from the v8_sse2.gyp
file that is automatically generated from v8.gyp using a small script I
wrote, which is also included in the patch.
* Mon Jan 18 2016 Kevin Kofler <Kevin@tigcc.ticalc.org> - 5.6.0-0.14.beta.nosse2.1
- Build V8 as a shared library on i686 to allow for swappable backends
This is the first prerequisite step towards building both the x87 and
SSE2 backends.
* Remove the -ffloat-store workaround: The media player issue that
caused problems with x87 floating point (and ultimately made upstream
require SSE2) should already be fixed / worked around by:
https://crrev.com/d2c745b13c93ecff5108bed57d8e052126715492
So I will only readd -ffloat-store if people request it, and even
then, only to specific parts of code and not everything.
* Fix src/3rdparty/chromium/third_party/WebKit/Source/platform/audio/
DirectConvolver.cpp to not require SSE2 on x86. (No runtime detection,
sorry.)
* Update the changelog date in the specfile.
See https://bugzilla.redhat.com/show_bug.cgi?id=1244196#c22 for the
history of the patch. Compared to the last revision there (v5):
* I fixed WebGLImageConversion.cpp to not assume SSE2 on x86.
Unfortunately, it would be really hard to make runtime detection work
there, because it uses intrinsics in inline templates, and GCC only
supports intrinsics when building the whole code for the vector
instruction set. So I had to turn off that SSE2 code entirely when
__SSE2__ is not defined at compile time.
* I fixed webrtc to check for SSE2 at runtime (using the runtime
checking code that webrtc already has and uses in several places)
before attempting to use OpenMAX on x86. OpenMAX requires SSE2.
So we just fall back to the Ooura implementation of FFTs when needed.
TODO: build V8 shared and twice (once for x87, once for SSE2)
* Thu Jan 14 2016 Kevin Kofler <Kevin@tigcc.ticalc.org> - 5.6.0-0.13.beta
- Drop nss321 backport (and the related nss-headers patch), it did not help
- Do an NSS/BoringSSL "chimera build" as will be the default in Chromium 47
- Update License accordingly (add "OpenSSL")
- Fix the "chimera build" to call EnsureNSSHttpIOInit (backport from Chromium)
* Wed Jan 13 2016 Kevin Kofler <Kevin@tigcc.ticalc.org> - 5.6.0-0.12.beta
- Update forked NSS SSL code to 3.21, match system NSS (backport from Chromium)
* Tue Jan 12 2016 Kevin Kofler <Kevin@tigcc.ticalc.org> - 5.6.0-0.11.beta
- Add an (optimistic) ExclusiveArch list because of V8 (tracking bug: #1298011)
* Tue Jan 12 2016 Kevin Kofler <Kevin@tigcc.ticalc.org> - 5.6.0-0.10.beta
- Unbundle prtime.cc, use the system NSPR instead (which is already required)
- Unbundle icu_utf.cc, use the system ICU instead (which is already required)
* Mon Jan 11 2016 Kevin Kofler <Kevin@tigcc.ticalc.org> - 5.6.0-0.8.beta
- Build against the system libvpx also on F23 (1.4.0), worked in Copr
It turns out the 1.5.0 requirement
(https://code.google.com/p/chromium/issues/detail?id=494939) is only for
portions of Chromium that QtWebEngine does not build.
