$TenDRA$ TenDRA Change Log. Only significant changes are listed in this document, they're broken down into the following categories: * API - Changes related to APIs, such as C99 and SUSv3. * Arch - Changes related to support of new architectures. * Behaviour - Changes in the behaviour of a program or system. (eg. output), * Bugfix - Changes that fix known bugs. * Build - Changes to the build infrastructure, (eg. nwe platforms) * Codebase - General changes to the codebase, (major source changs) * Enhancement - New features. * OS support - Changes in the operating systems supported (add/remove) ---- 2005-11-07 API * Semantics of C99's inline specifier fixed. 2005-11-05 API * Initial version of C99's header, the PRI and SCN macros are still missing. 2005-11-01 API * The xpg3 API is now built by default. 2005-10-30 API * The -Yc99 flag can now be combined with -Xmode. 2005-10-27 Bugfix * Fixed C producer bugs for tentative definitions. 2005-10-26 Bugfix * Maximum line number in #line directives made adjustable. 2005-10-26 Bugfix * Tcc's -KPIC option now works on FreeBSD/80x86. 2005-10-24 Bugfix * Make the C++ producer allow 'return voidexp;'. 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. 2004-09-04 Codebase * Imported generic, low-level TDF manipulation library as part of libten. Converted tools, producers andinstallers to use library functions for TDF manipulations. 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. 2004-06-08 Codebase * Converted tnc to the libten platform. 2004-06-02 API * Implemented placemarkers as described in ISO/IEC 9899:1999. 2004-06-02 Bugfix * 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 * Initial support for the C99 function specifier inline. 2004-05-25 Behaviour * The sid option -? has been moved to -h (help), and the -v option has been moved to -V (version). 2004-05-25 Behaviour * The make_tdf option -v has been moved to -V (version). 2004-05-25 Behaviour * The lexi option -v has been moved to -V (version). 2004-05-25 Behaviour * The calculus option -v has been moved to -V (version), and the -q option has been moved to -v (verbose). 2004-05-25 Behaviour * The tspec option -C (copyright) has been removed. 2004-05-25 Behaviour * The tnc options -v and -V have been swapped. The -v option now enables verbose mode, while the -V option reports version. 2004-05-25 Behaviour * The pl option -v has been moved to -p (PrettyPrint). 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 * The producer options -v and -V have been swapped. The -v option now enables verbose mode, while the -V option reports version. The option -? has been deleted as it is identical to -h (help). 2004-05-25 Behaviour * The 80x86 trans option -h has been moved to -j (do not use .bss segment). 2004-05-25 Behaviour * The alpha trans options -v and -i have been removed, as they are identical to -V (version). 2004-05-25 Behaviour * The hppa trans option -h has been moved to -g (similar to GCC's -g). The option -? has been removed. 2004-05-25 Behaviour * The mips trans option -B on ULTRIX has been removed, as it is identical to -F. The option -Q now exits indicating success rather than failure for both IRIX and ULTRIX. 2004-05-25 Behaviour * The aix trans option -D has been added as a placeholder. 2004-05-23 Behaviour * Eliminate the need to pass -Ytdf_ext in addition to -Yc99 for some expressions with long long operands. 2004-05-14 Codebase * Converted tspec to the libten platform. 2004-05-12 API * Initial support for the C99 _Bool type. 2004-05-01 Codebase * Added startup files for the ISO99 API. 2004-04-21 Codebase * Converted tcc to the libten platform. 2004-04-10 API * Reimplemented C99's , ;, , and .

A new option in config.mk, USE_PATH_DEV, can be set to return to the previous behaviour. 2004-03-28 Build * Added a new version of tendra.version.mk which holds all version information for TenDRA. 2004-03-27 OS Support * Split support for FreeBSD into 4.x and 5.x. 2004-03-23 API * Implemented C99's and finish , , and . 2004-03-23 Build * Introduce the SRC_MACHINES variable, which similarly to SRC_ENV holds the path to files in src/lib/machines.

ELF is now the default FreeBSD output format. 2002-12-16 API * Added framework files for ISO99. 2002-12-14 Enhancement * tcc now has a -vt flag to dump verbose information about each step in the toolchain, including the argv given to each stage. Additionally, tcc now has a -ve flag to dump very verbose information about the environment used in each step of the toolchain. 2002-12-11 Bugfix * tspec and calculus now print non-error verbose output to stdout instead of stderr. 2002-12-05 Behaviour * sid now outputs ansi-c instead of ossg-c. 2002-12-01 Behaviour * Added -y option to tcc used to modify the relative location of the environment files specified by -Y arguments.
