4 * add a new tool: sindex - the semantic utility
5 Sindex is a simple to use cscope-like tool but understanding
6 how symbols are used and which can track struct members.
8 * add support for GCC's __auto_type
10 * add support for _Generic
12 * fully propagate declarations downward.
13 For example, it means that code like::
16 int foo(void) { return 0; }
18 now behaves as expected: foo() is effectively static.
21 * allow a single sparse executable to be used for multiple architectures
22 * add support for -mcmodel & -f{pic,PIC,pie,PIE}, mainly for RISC-V
23 * add new option, --arch=$ARCH, to specify the target architecture
24 * move all arch-specific code into separate files (target-$ARCH.c)
25 * try to support the various floating-point ABIs on ARM
26 * fix wchar_t & wint_t for openbsd
27 * add missing predefines for PPC
28 * add missing predefines: __amd64 & __amd64__
29 * sparc32 on SunOS/Solaris uses 128-bit long double
30 * fix wchar_t & wint_t on SunOS/Solaris
31 * teach sparse about -fshort-wchar
32 * keep cygwin specifics with i386/x86-64 specifics
33 * keep BSD & Darwin specifics with i386/x86-64 specifics
34 * fix the signedness of plain chars
35 * add support for s390 (ILP32)
36 * add predefine for __mips__
37 * predefine "i386" if needed
38 * pre-define __unix__ and friends
39 * add necessary defined for sunos-derived systems
40 * improved detection of the native OS
43 * improve diagnostic message about wrong redeclaration
44 * conditionally accept { 0 } without warnings
45 * add -Wexternal-function-has-definition
46 * display the bitfield name in error messages
47 * oversized bitfields are now errors
48 * add an option to suppress warning 'no newline at EOF'
49 * warn when jumping into statement expressions
50 * warn when using undefined labels
51 * warn on defined but unused labels
54 * allows '__<attribute-name>__' for all attributes.
55 * improve handling of function attributes
56 * separate modifiers into type/declaration
57 * add support for attributes 'unused' & 'gnu_inline'
58 * simplify parsing of inline/__tls/__visible
59 * better handle function-only attributes
60 * teach sparse about gnu_inline
61 * parse enum attributes and, for now, ignore them
64 * use -fshort-char for Cygwin
65 * add support for riscv32 & riscv64
66 * don't define __CYGWIN32__ on 64-bit
67 * filter-out sparse-specific -msize-long & -msize-llp64
68 * use -mfloat-abi=hard for armhf
69 * define _BIG_ENDIAN when needed
70 * remove definition of _STRING_ARCH_unaligned (defined by glibc)
71 * removed unneeded predefines for integers (now defined by sparse)
72 * better multi-arch support by using --arch=$ARCH
75 * avoid standard includes in the tests
76 * fix testcase with non-constant initializer
79 * add support for the linearization of builtins
80 * generate OP_UNREACH from __builtin_unreachable()
81 * add OP_UNREACH after calls to __noreturn functions
84 * do not use obsolete sphinx's AutodocReporter
85 * Sphinx's minimal version is now 1.7
86 * add basic doc about the type system
87 * doc is now accessible as: https://sparse.docs.kernel.org
88 * release notes (old and current ones) have been added to the doc
89 * now using the sphinx_rtd_theme instead of the classic theme
92 * add support for '-std=c17/c18'
93 * simplify testing of which version of the standard is used
94 * ensure that typeofs are evaluated before using show_typename()
95 * use a single way to expand typeofs
96 * various improvements to the 'dissect' tool
97 * simplify the parsing of type specifiers
98 * improve diagnostic messages concerning bitfields
99 * fix premature examination of dereferenced object
100 * various fixes for the expansion of constant symbols
101 * fix type compatibility of _Atomic types
102 * add support for builtin macros with argument
103 * add support for __has_feature() & __has_extension()
