* Type Based Alias Analysis (TBAA) is now implemented and turned on by default
in Clang. This allows substantially better load/store optimization in some
cases. TBAA can be disabled by passing -fno-strict-aliasing.
* This release has seen a continued focus on quality of debug information. LLVM
now generates much higher fidelity debug information, particularly when
debugging optimized code.
* Inline assembly now supports multiple alternative constraints.
* A new backend for the NVIDIA PTX virtual ISA (used to target its GPUs) is
under rapid development. It is not generally useful in 2.9, but is making
rapid progress.
* Added a DO server which allows modification of internal data
structures using a simple interface.
* Tooltips now show the object name and the object type for
informational purposes.
* Opens default document when using NSWindows95InterfaceStyle.
* Correction for some nib loading issues.
* Limited support for standalone views.
* Fixes for various bugs.
Other notable changes include:
* implement pattern colours for all backends
* use DejaVu as another fallback font
* OpenGL fixes and improvements
* Key repeat support implemented in X11
* Add live resize in NSSplitView
* Toolbars have been completely rewritten and improved
* New Mac OS X 10.5 methods in NSFont
* Bug fixes and stability improvements
* Parallel building supported using e.g. make -j 2
* Support source files in subdirectories without using a subproject.
* Support header files in sub-subdirectories.
* Batch-compile Java files (much faster).
* Fixes for building documentation.
Changes from version 3.0.0 to version 3.0.1:
- Bug fixes (see <http://www.mpfr.org/mpfr-3.0.0/#fixed> or ChangeLog file).
Note: The mpfr_subnormalize implementation up to MPFR 3.0.0 did not change
the flags. In particular, it did not follow the generic rule concerning
the inexact flag (and no special behavior was specified). The case of the
underflow flag was more a lack of specification.
New in 2.10:
* Support for Linux/S390.
<sigsegv.h> now defines a macro SIGSEGV_FAULT_ADDRESS_ALIGNMENT.
It is either 1 or pagesize. Its meaning is that
- The fault address passed to a SIGSEGV handler has been rounded down
to a multiple of SIGSEGV_FAULT_ADDRESS_ALIGNMENT.
- The address and length arguments of sigsegv_register function calls
must be multiples of SIGSEGV_FAULT_ADDRESS_ALIGNMENT.
* Faster distinction between stack overflow and other fault on OpenBSD.
* "git apply" used to confuse lines updated by previous hunks as lines
that existed before when applying a hunk, contributing misapplication
of patches with offsets.
* "git branch --track" (and "git checkout --track --branch") used to
allow setting up a random non-branch that does not make sense to follow
as the "upstream". The command correctly diagnoses it as an error.
* "git checkout $other_branch" silently removed untracked symbolic links
in the working tree that are in the way in order to check out paths
under it from the named branch.
* "git cvsimport" did not bail out immediately when the cvs server cannot
be reached, spewing unnecessary error messages that complain about the
server response that it never got.
* "git diff --quiet" did not work very well with the "--diff-filter" option.
* "git grep -n" lacked a long-hand synonym --line-number.
* "git stash apply" reported the result of its operation by running
"git status" from the top-level of the working tree; it should (and
now does) run it from the user's working directory.
* various build-fixes for the rpm/dpkg scripts.
* add "--enable-rpath-link" option to Ada95/configure, to allow
packages to suppress the rpath feature which is normally used for
the in-tree build of sample programs.
* corrected definition of libdir variable in Ada95/src/Makefile.in,
needed for rpm script.
* add "--with-shared" option to Ada95/configure script, to allow
making the C-language parts of the binding use appropriate compiler
options if building a shared library with gnat.
