- Noteworthy changes to the RISC OS GCCSDK
-
- RISC OS GCC release 3.4.1 release 1 (released 05 October 2004)
- =======================================
-
- * gcc: Updated to version 3.4.1 to make the distribution current and
- bring in speed improvements and better optimisation. The 3.3 release
- branch was abandoned in favour of this.
-
- * gcc: Default is now to tune for XScale - this will improve performance
- on StrongARM and XScale processors - the most common ARM processors running
- RISC OS.
-
- * Many substantial changes and improvements - see docs.ULChanges for the
- complete list. Highlights include:
-
- - Integrated iconv support via an external module.
- - Much improved handling of child processes, avoiding previous
- potential aborts.
- - Miscellaneous pthreads improvements including addition of semaphore
- support.
- - Complete set of 64-bit maths functions.
- - Considerably improved compatibility with glibc headers, easing
- porting of many programs.
- - Improved terminal handling.
- - /dev/dsp support meaning some Unix programs using sound will work
- without modification.
- - Further improvements to filename translation.
- - General improvements to source formatting and comments.
-
-
- RISC OS GCC release 3.3.3 pre-release 2 (released 18 April 2004)
- =======================================
-
- * diffutils: Upgrade to version 2.8.1. Add documentation.
-
- * flex: Upgrade to version 2.5.31. Add documentation.
-
- * grep: Upgrade to version 2.5. Add documentation.
-
- * gperf: Add documentation.
-
- * make: Upgrade to version 3.80. Add documentation.
-
- * patch: Upgrade to version 2.5.4.
-
- * sed: Upgrade to version 4.0.9. Add documentation.
-
- * gcc: Fix accidental commit that prevented error messages for compiled
- files from being displayed.
-
- * unixlib: Preserve DDEUtils Prefix upon parent process exit. This fixes
- an interaction bug between AMU and gcc causing files to be stored in
- the wrong place.
-
- * drlink: Fix handling of RISC OS filenames.
-
- RISC OS GCC release 3.3.3 pre-release 1 (released 20 March 2004)
- =======================================
-
- * unixlib: Path <Unix$Path> has been replaced by <UnixLib$Path>. All
- makefiles that previously used the path Unix: will have to be updated
- to use UnixLib: instead.
-
- * gcc: updated to release 3.3.3 20040214. The Standard C++ Library
- has undergone a re-write, meaning any applications compiled with this
- C++ compiler are not compatible with previous GCC releases.
-
- * unixlib: POSIX thread (pthread) support
-
- * gcc, unixlib, libscl: Default build is now APCS-32. APCS-26 builds are
- deprecated and will be removed from a future version.
-
- * gcc: C++ and Fortran applications can now be compiled to use the
- SharedCLibrary (libscl) as an alternative to UnixLib. UnixLib
- remains the default target C run-time library.
-
- * unixlib: Stack model changed from UNIX-style linear stacks
- to RISC OS SharedCLibrary style chunked stacks. This allows
- for automatic WimpSlot extension.
-
- * unixlib: Emulation of /dev/random and /dev/zero.
-
- * unixlib: New resolver libraries, taken from glibc 2.2.5.
-
- * unixlib: Improve compatibility with the C99 standard.
-
- * unixlib: New crypt implementation, taken from glibc 2.2.5.
-
- * as: Big-endian processor support. Required for cross-compiling on
- * processors such as the MIPS.
-
- * as: Fixes for common area symbol handling
-
- * as: Support for ELF object format.
-
- * as: Improve filename handling and search paths for GET.
-
- * ar: Closer emulate UNIX's 'ar' implementation.
-
- * sed: Upgrade to version 4.0.7.
-
- RISC OS GCC release 2.95.4 release 3 (released 05 January 2003)
- ====================================
-
- * as: Fix pre/post indexed addressing assembler error.
-
- * gccsdk: Support NetBSD.
-
- * unixlib: Fix #include typo in inttypes.h.
-
- * libscl: Preserve flags on 26-bit systems.
-
- RISC OS GCC release 2.95.4 release 2 (released 13 November 2002)
- ====================================
-
- * ar: This is an ALF implementation of the Unix archiver. This is
- simply a front end onto libfile but takes compatible arguments.
-
- * nm: Based on decaof, this program is an AOF version of the Unix
- program to list symbols in object files.
-
- * as: Fix broken co-processor mnemonic support.
-
- * drlink: Upgrade from 0.3.4 to 0.3.9.
-
- * unixlib: Fix a command line argument bug when using file-descriptor
- based re-direction.
-
- * unixlib: Logic for isprint was wrong.
-
- * unixlib: usleep gets 1/100th sec resolution.
-
- * gcc: Support hh and icc filename extensions.
-
- * gcc: [BUG48] Tail call optimisation and chunked stacks.
-
- * gcc: [BUG88] Prevent STR code generation where the source and base
- register are the same.
-
- * bison: [BUG26] Pack bison files in the distribution.
-
- * libscl: Support APCS-32.
-
- RISC OS GCC release 2.95.4 release 1 (released 20 December 2001)
- ====================================
-
- * unixlib: Allow for program independent sfix settings.
-
- * unixlib: Remove restriction on the maximum length of a command line.
-
- * unixlib: Add wchar.h, inttypes.h, stdint.h and supporting functions.
-
- * unixlib: Support `,xyz' RISC OS file type extensions.
-
- * unixlib: Fix longstanding bug that causes programs to hard-lock a
- computer whilst using the network stack.
-
- * unixlib: Support for DoggySoft's Syslog module.
-
- * unixlib: Header file re-arrangements so that UnixLib can be used
- as a drop-in compile time replacement for the SharedCLibrary.
-
- * gcc: Remove weak symbol use that was enabled in pre-release 3.
-
- * gcc: Changed compiler executable directory from arm-riscos to
- arm-acorn-riscos.
-
- * gcc: Minor code generation optimisation for small C++ functions.
-
- * gcc: Bug fix in Unix filename translation. Pathnames starting with
- `../../something' would be translated to '../../'.
-
- * gcc: By default the libraries and headers for UnixLib and SharedCLib
- are integrated into the distribution. GCC therefore no longer relies
- on the Unix$Path and C$Path variables. During the link stage, it is
- recommended that the GCC command is used, rather than calling drlink
- directly.
-
- * gcc: The option specifying that source code should be built and linked
- against the SharedCLibrary rather than UnixLib has changed from the
- rather uninformative -mstubs to -mlibscl.
-
- * as: Better support for local labels.
-
- * gcc: Upgraded to version 2.95.4.
-
- RISC OS GCC pre-release 3a (released 23 November 1999)
- ==========================
-
- * Integer division will now raise a SIGFPE upon division
- by zero
-
- * Front-end programs g77 and g++ had not been built since the
- upgrade to 2.95.2 and were looking for the compilers in
- directory 2_95_1.
-
- * The !run file incorrectly set the pathname for the /tmp
- directory.
-
- RISC OS GCC pre-release 3 (released 19 November 1999)
- =========================
-
- These are the user visible changes since pre-release 2.
-
- * Updated to GCC 2.95.2
-
- * C++: The Standard Template Library headers have been moved from
- their own sub-directory (stl) to their parent directory.
-
- * Fix errors in the conversion of float/double and long doubles
- to 64-bit integers. These functions have been re-coded to not
- use floating-point instructions.
-
- * as: The assembler incorrectly compiled a post-indexed LDR/STR
- as a pre-indexed LDR/STR.
-
- * as: Incorrect filename translation was causing AOF files
- named o.s_temp to be written out as o.o_temp
-
- * unixlib: Bug fixes in UnixLib's strsep and strtoul functions.
- Implemented C9X headers, fenv.h and complex.h. Added many new
- math functions.
-
- RISC OS GCC pre-release 2 (released 23 September 1999)
- =========================
-
- This file details the user visible changes since pre-release 1.
-
- * Separate libgcc runtime library for targetting the SharedCLibrary
- called libgcc_sh.
-
- * Exception handling bug fix.
-
- * Transparent suffix swapping performed by UnixLib is now private
- to the GCC compilers and utilities (set by UnixFS$<progname>$sfix)
-
- * Directory structure has been reorganised. Binaries and
- supporting libraries are now in version specific directories so
- it will be possible to have multiple gcc installations and select
- an appropriate compiler by it's version number (see `gcc -V').
-
- * C++ support libraries libio and libstdc++ are now integrated
- into the main !gcc tree, rather than being separate directories.
- Hence it is no longer a requirement to add -Ilibio: and -Ilibstdc:
- to the gcc command line, likewise with -Llibio: and -Llibstdc:
- on the linker command line, however you still will need to add
- -lstdc++ and -liostream.
-
- * The C++ libraries should now be compatible with the long
- file name feature of RISC OS 4. This shouldn't affect users of
- filing systems that support only 10 characters i.e. ADFS, IDEFS
- and SCSIFS on RISC OS 3.
-
- * The example programs originally located in !gcc.files have been
- moved out of the !gcc directory. Running !gcc will no longer
- change the currently selected directory.
-
- * Documentation update to reflect directory structure changes.
- Added a clear note regarding the memory usage of gcc.
