Changelog

v2.2

Added support for DWARF 1 symbol tables.
Improved support for bitfields.
Improved support for 128-bit types.
Added support for parsing .gnu.linkonce.* section names.
Added support for parsing -fdata-sections and -ffunction-sections section names.
Mac builds compiled for x64 processors are now provided in addition to the arm64 builds.
demangle: A newline is now printed at the end of the output.
stdump: The functions and globals subcommands now output a header comment like the types command.
stdump: Added --compact option to omit whitespace and newlines from JSON output.
stdump: The output format of the files subcommand has been updated.
stdump: A crash in the command line parser has been fixed.

Variable symbols are no longer incorrectly deduplicated as if they were types.
The static keyword is no longer missing from the output for static global variables.
Structs defined inside global variable definitions are now printed with the correct C++ syntax.
Fixed an issue where in some cases null addresses would be handled incorrectly.
Glibc-based Linux builds are now provided in addition to the musl-based builds.
stdump: In C++ output, stack variable offsets will now be relative to the value of the stack pointer register for the current function by default.
stdump: Added includes subcommand.
stdump: Added --procedures option.
stdump: Added --sort-by-address option.
stdump: Added --caller-stack-offsets option.

New features and changes:

Added support for ELF and SNDLL symbol tables.
Rewrote core symbol table data structures.
Overhauled the JSON format.
Massively reduced memory usage.
Reworked error handling.
Overloaded operator function names are now demangled.
Reworking the command-line interface of both stdump and uncc, adding many new options.
stdump: Fixed issue where the headers option (previously mdebug) would display some sizes as counts.
stdump: Demangling is now performed automatically unless --dont-demangle-names is passed.
uncc: Improve how pointers to global variables in other global variable data are printed.

A bunch of .mdebug symbol table parsing issues have been fixed:

Virtual inheritance is now detected.
The logic for determining if a struct was defined using a typedef has been fixed.
Handled some rare cases where corrupted STABS strings could be generated for certain instantiated template types.
Some redundant STABS base class information is now parsed. The previous behaviour would very rarely cause some other symbols in the same translation unit to be parsed incorrectly.
Certain cases where incorrect function symbols would be emitted are now caught and handled.
A compiler bug where the STABS type for a structure or union would be recursively emitted inside its own definition is now handled.
A rare case where relative addresses were incorrectly emitted for static functions is now handled better.

Fixed detection of bitfields where the underlying type is a typedef.
Fixed a rare bug where unsigned 32-bit integer types were incorrectly classified as 64-bit types.
Improved how floating point literals are printed for global data.

stdump: A type dependency graph can now be generated.
stdump: There is now an option to list the source files associated with each ELF section.
uncc: Data types are now printed. It guesses which types belong to which files based on multiple heuristics.
uncc: If a FUNCTIONS.txt file is provided, code from that file will be included in the output.
uncc: The initial values of global variables are now printed as initializer lists and literals.
uncc: The implicit this parameter of member functions will now be omitted from parameter lists.
uncc: The parameter lists of member function declarations will now not all be empty.

Added demangle tool.
Added uncc tool.
The end of a function in the symbol table is now identified correctly so that extra local variables are not erroneously generated.
The type deduplication algorithm has been improved.
stdump: Fixed a bug where global variables would be printed to stdout even if an output file was specified.
