V0.6.2
======

* add a new tool: sindex - the semantic utility
    Sindex is a simple to use cscope-like tool but understanding
    how symbols are used and which can track struct members.

* add support for GCC's __auto_type

* add support for _Generic

* fully propagate declarations downward
  For exemple, it means that code like:

        static int foo(void);
        int foo(void) { return 0; }

  now behaves as expected: foo() is effectively static

* multi-arch:
  * allow a single sparse executable to be used for multiple architectures
  * add support for -mcmodel & -f{pic,PIC,pie,PIE}, mainly for RISC-V
  * add new option, --arch=$ARCH, to specify the target architecture
  * move all arch-specifc code in separated files (target-$ARCH.c) 
  * try to support the various floating-point ABIs on ARM
  * fix wchar_t & wint_t for openbsd
  * add missing predefines for PPC
  * add missing predfines: __amd64 & __amd64__
  * sparc32 on SunOS/Solaris uses 128-bit long double
  * fix wchar_t & wint_t on SunOS/Solaris
  * teach sparse about -fshort-wchar
  * keep cygwin specifics with i386/x86-64 specifics
  * keep BSD & Darwin specifics with i386/x86-64 specifics
  * fix the signedness of plain chars
  * add support for s390 (ILP32)
  * add predefine for __mips__
  * predefine "i386" if needed
  * pre-define __unix__ and friends
  * add necessary defined for sunos-derived systems
  * improved detection of the native OS

* warnings
  * improve diagnostic message about wrong redeclaration
  * conditionally accept { 0 } without warnings
  * add -Wexternal-function-has-definition
  * display the bitfield name in error messages
  * oversized bitfields are now errors
  * add an option to suppress warning 'no newline at EOF'
  * warn when jumping into statement expressions
  * warn when using undefined labels
  * warn on defined but unused labels

* attributes:
  * allows '__<attribute-name>__' for all attributes.
  * improve handling of function attributes
  * separate modifiers into type/declaration
  * add support for attributes 'unused' & 'gnu_inline'
  * simplify parsing of inline/__tls/__visible
  * better handle function-only attributes
  * teach sparse about gnu_inline

* typeof:
  * ensure that typeofs are evaluated before using show_typename()
  * use a single way to expand typeofs

* cgcc:
  * use -fshort-char for Cygwin
  * add support for riscv32 & riscv64
  * don't define __CYGWIN32__ on 64-bit
  * filter-out sparse-specific -msize-long & -msize-llp64
  * use -mfloat-abi=hard for armhf
  * define _BIG_ENDIAN when needed
  * remove definition of _STRING_ARCH_unaligned (defined by glibc)
  * removed unneeded predefines for integers (now defined by sparse)
  * better mult-arch support by using --arch=$ARCH

* testsuite:
  * avoid standard includes in the tests
  * fix testcase with non-constant initializer
    
* IR
  * add support for the linearization of builtins
  * generate OP_UNREACH from  __builtin_unreachable()
  * add OP_UNREACH after calls to __noreturn functions

* doc:
  * do not use obsolete sphinx's AutodocReporter
  * add basic doc about the type system
  * doc is now accessible as: https://sparse.docs.kernel.org

* misc:
  * add support for '-std=c17/c18'
  * simplify testng of which version of the standard is used
  * various improvements to the 'dissect' tool
  * simplify the parsing of type specifiers
  * improve diagnostic messages concerning bitfields
  * fix premature examination of dereferenced object
  * various fixes for the expansion of constant symbols
  * fix type compatibility of _Atomic types
