[Bug 1084852] Re: Chromium still tries to enable NEON on arm* builds when told not to

 

This bug was fixed in the package chromium-browser -
23.0.1271.97-0ubuntu0.12.10.1

---------------
chromium-browser (23.0.1271.97-0ubuntu0.12.10.1) quantal-security; urgency=low

  * Omit resources/extension/demo files from any packaging verification
    because they're unwanted.
  * debian/chromium-driver.install: install chromedriver
  * Update README.source to include some of these changes.
  * Set new URL for channel-release info in rules file.
  * debian/patches/chromium_useragent.patch.in renamed to drop ".in",
    OS "Ubuntu" hardcoded with no compilation-release name, and patch
    refreshed to follow new location of source.  Also remove it
    from the list of ephemeral files that "clean" rule removes.
  * In debian/rules, use "-delete" flag on find instead of "-exec rm {} \;",
    to be safer and faster.
  * Make most patches follow a common format (no timestamps or Index lines), to
    avoid future churn.
  * Write the "REMOVED" list files to the root of the orig tarball,
    instead of inside the src/ directory, where they could collide.
  * Fix dpkg-source warning: Clean up python cached bytecode files.
  * Also don't include python bytecode or cache files in orig tarball,
    and clean then up on "clean" rule.
  * Fix dpkg-source warning: Remove autoconf cache.
  * Fix lintian warning: fta and micahg to XSBC-Original-Maintainer.
  * Fix lintian error not-binnmuable-all-depends-any.
  * Override lintian complaints ancient-autotools-helper-file and
    unused-build-dependency-on-cdbs.
  * Drop "lzma" from build dependencies.
  * Set default binary and source package compression to xz. If
    building for Ubuntu 10.04, then make binary's compression to bzip2.
  * List explicit architectures that Chromium supports, instead of "any".
    Cr {arm ia32 x64} map into Debian {armhf armel i386 amd64}.
  * debian/patches/arm-neon.patch added to get ARM w/o Neon support.
    (LP: #1084852)
  * In debian/rules, avoid creating invalid subst expression in sed
    of DEBIAN* vars into files.
  * Note localization in package description for support for ast, bs, en-AU,
    eo, hy, ia, ka, ku, kw, ms.
  * No longer include Launchpad-generated translations.  Disable patch
    grd_parse_fix.patch .
  * Set default binary and source package compression to xz. If
    building for Ubuntu 10.04, then make binary's compression to bzip2.
  * No longer expect unpacked tarball to contain "build-tree".
  * Fix build warning about missing debian/source/format.  Set to "3.0
    (quilt)".
  * Remove unnecessary glib-header-single-entry.patch .
  * Manually set DEB_{BUILD,HOST}_ARCH when not already set, like when the
    executing program is not dpkg-buildpackage.
  * Make rules file generate LASTCHANGE file at new location.
  * Change get-sources command to kill script when it fails to disable
    gyp-chromium run from DEPS. Never fail silently again.
  * Add patches/struct-siginfo.patch to work around source bug in dereferencing
    internal stuct instead of public type.
  * Refresh patches from lp:unity-chromium-extension .
  * Make all patches follow a common format, to avoid future churn.
    No timestamps, a/b parent, sorted, no index.
  * New upstream version 23.0.1271.97
