  • Bugfix - Changes that fix known bugs.
  • Build - Changes to the build infrastructure, (eg. nwe platforms)

2005-10-22 Bugfix

  • Fixed a bunch of bugs in tcc (-P, -Ystatus, -info, -show_env).

2005-10-20 Bugfix

  • Fixed a bug in the producers if both -n and -e werespecified.

2005-10-19 Codebase

  • Removed non-working environments: aes, motif_1_1 andmse.

2005-10-18 Behaviour

  • Allow --version in tld and tnc.

2005-10-17 Bugfix

  • Fixed the tchk script.

2005-10-17 Bugfix

  • Fixed spec file reading in the producers (-s file).

2005-10-17 Enhancement

  • Tcc taught about .S files (assembler files with preprocessor directives).

2005-10-16 API

  • Implemented C99's _Pragma preprocessing operator.

2005-10-10 API

  • Implemented C99's hexadecimal floating pointliterals.

2005-07-22 API

  • Allow post- and prefix increments and decrements on_Bool.

2004-10-17 API

  • Implemented C99's flexible array members.

2004-10-17 API

  • Implemented C99's flexible array members.

2004-08-15 Codebase

  • Converted producers to the libten platform.

2004-06-19 Codebase

  • All tools and utilities (except tcc) now use the new command line option parser provided by libten. Long options using a single dash now require a double dash.

  • Concatenation of empty macro arguments fixed to conform to C99.

2004-06-02 Enhancement

  • The producers can now print dependency information usable for make(1) by using the new option -i. Passing -iM causes all headers to be printed, while passing -iMM causes only the headers between double quotes to be printed. At the moment this requires -Wp,-iM -E (-Wg,-iM -E for C++ files) to be passed to tcc.

2004-05-25 Codebase

  • Retired the CONST macro; we require C90 compilers for TenDRA.

2004-05-28 API

2004-05-25 Behaviour

2004-05-25 Behaviour

  • The disp option -h has been moved to -a (alignment spacing). The option -V has been moved to -r (don't rationalise output). The option -U has been moved to -l (print usage/linkage information). The option -v has been moved to -V (version). The option -p has been moved to -v (verbose).

2004-05-25 Behaviour

2004-05-25 Behaviour

  • The 80x86 trans option -h has been moved to -j (do not use .bss segment).
