  * Updated to latest tccx work, fixing struct alignment issues and
    enum handling..

0.11  Mon, Aug 8, 2016

  [DIFFERENT BEHAVIOR]
  
  * The binary, library, and include file locations are reported based on
    the results of an actual subdirectory search, rather than by sheer
    guesswork, as used to be the case.
  
  [BUG FIXES]
  
  * BSDs were switched to use cc, but that is clang (at least on some
    BSDs) so we need to add the heinous-gnu-extensions flag.
  
  * Add patch for Mac OSX to #define _VA_LIST_T. Macs were hitting trouble
    with incompatible preprocessor definitions. If the macros and internal
    definitions had all been expanded, the definitions for variadic function
    lists would have been the same, but tcc doesn't know that.

src/Changelog  view on Meta::CPAN

- fixed array declaration in old style function parameters
- support casts in static structure initializations
- added various __xxx[__] keywords for GCC compatibility
- ignore __extension__ GCC in an expression or in a type (still not perfect)
- added '? :' GCC extension support

version 0.9.15:

- compilation fixes for glibc 2.2, gcc 2.95.3 and gcc 3.2.
- FreeBSD compile fixes. Makefile patches still missing (Carl Drougge).
- fixed file type guessing if '.' is in the path.
- fixed tcc_compile_string()
- add a dummy page in ELF files to fix RX/RW accesses (pageexec at
  freemail dot hu).

version 0.9.14:

- added #warning. error message if invalid preprocessing directive.
- added CType structure to ease typing (faster parse).
- suppressed secondary hash tables (faster parse).
- rewrote parser by optimizing common cases (faster parse).

@section X86 Assembler
@cindex assembler

All X86 opcodes are supported. Only ATT syntax is supported (source
then destination operand order). If no size suffix is given, TinyCC
tries to guess it from the operand sizes.

Currently, MMX opcodes are supported but not SSE ones.
