I have tagged and tarballed a 0.3 release of Sparse, now available from
<http://kernel.org/pub/software/devel/sparse/dist/sparse-0.3.tar.gz>,
with sha1sum `1d868b29234176abd5f3f5463aad1f11d5268dc2`.
Note that the Sparse Git repository has moved to:
git://git.kernel.org/pub/scm/devel/sparse/sparse.git
The old repository location will continue to work for now, but please update
any references you have to the old location.
Thanks to Christopher Li for contributing heavily to this release, including
several notable new features. See the full changelog for details.
In addition to numerous bug fixes, cleanups, and new test cases, this release
includes several new visible features:
* A Sparse-based implementation of ctags, thanks to Christopher Li. Now you
can have a ctags that **actually parses C**.
* Sparse now correctly supports annotations on inline functions.
* The new `-ventry` option will make Sparse dump its internal linearized
bytecode format.
* Sparse now parses the `__regparm__` attribute just like `regparm`, fixing a
warning with pthreads from glibc 2.5.
* Sparse now interprets the integer size attributes `QI`, `SI`, `HI`, and `DI`,
and their double-underscore variants.
* Sparse now supports attributes on labels, sometimes used to specify `unused`
labels.
* Sparse now handles structure attributes between the structure keyword and the
name, fixing many parse errors.
* Sparse now supports more than one command-line include file.
* The pkg-config file gets installed to its correct location under `lib`,
rather than under `share`.
Notable internal changes:
* Fully table-driven attribute parsing. This simplifies the C parser and makes
it far easier to add new attributes to Sparse.
* Many internal cleanups, more information preserved for backends, more useful
formats for that information, and lower memory usage.
* Fixed Sparse warnings about itself.

Introducing statement keywords
Free up some special bits in modifiers.
Moving statement parsing into smaller functions.
James Westby (2):
Fix mistaken comparison that becomes a no-op.
Update the information in README about using the library.
Josh Triplett (30):
Add ctags to .gitignore
Add a return in the last case of a switch; redundant but less error-prone.
Coding style fix: in a pointer type, * goes with the name, not the type.
Add missing #include "allocate.h" in linearize.h for DECLARE_ALLOCATOR.
Add test case for function pointer modifier inheritance
Add test case for structure attribute placement.
Add test case for double semicolon in structure declaration.
Coding style fix: use parentheses with sizeof
Move pkg-config file to lib, rather than share
Add static to declarations in test cases, to remove unrelated warnings.
Fix typo in symbol.h: s/keywrods/keywords/
Fix typos in comments
Use GCC format and sentinel attributes on appropriate functions
Fix two potential NULL pointer dereferences in dissect.c
Avoid returning an uninitialized pointer from dup_list of an empty list
Remove stray space from expand_compare in expand.c
Prevent potential NULL pointer dereference in expand_compare
Add test case for basic address_space annotations.
Use noreturn on die() and error_die()
Parse and ignore the __regparm__ attribute, just like regparm.
Fix comment to reference #weak_define rather than #ifndef, matching code
Teach cgcc about -Wtransparent-union and -Wno-transparent-union
Declare die_if_error extern in lib.h
Remove unused variable "include" from lib.c
Declare do_error static
Declare gcc_patchlevel extern in lib.h
compile-i386.c: Declare regs_in_use static
simplify.c: Declare delete_pseudo_user_list_entry static
linearize: DECLARE_ALLOCATOR for asm_constraint and asm_rules
Fix most -Wshadow warnings in Sparse.
Oleg Nesterov (3):
dissect: cleanup report_implicit()
dissect: fix multidimensional array initializer
dissect: simplify lookup_member()
