Version 2.08. Tagged as 'CLXLite-2_08'

When netfix_done() is #defined to nothing, it leaves behind empty if
statements.  Define it to {} so the if statements are correctly terminated.

Previously these functions were no-ops.  Replaced them with a POSIX
implementation.

Don't read from dh until after it is validated.
Found by cppcheck static analysis.

Version 2.07. Tagged as 'CLXLite-2_07'

Detail:
  Now uses environment variable RISCOS to point to root of source tree.
  This makes it easier to keep the two forks of each script in line when cloning the file for a component at a different directory depth, and also allows it to be overridden from the command line.

CLibrary now includes the others itself so we don't have to.
Resolve a couple of trivial warnings in the code.
Build, but not tested.

Version 2.06. Tagged as 'CLXLite-2_06'

Detail:
  Changed path to Env directory, assuming source trees are no longer merged


Version 2.05. Tagged as 'CLXLite-2_05'

Detail:
  c/wholefls - wf_save() was passing (start,length) to OS_File instead of (start,end), causing files to either be truncated or not saved at all
Admin:
  modsqz now works properly when linked against CLXLite
  Fixes bug #297, with thanks to hilltop


Version 2.04. Tagged as 'CLXLite-2_04'

Put the linefeed in some error messages in the wrong place. It's late.

Cocked-up the placement of an if() statement. Won't affect binary on RISC OS but would result in build errors on other systems.

Version 2.03. Tagged as 'CLXLite-2_03'

Detail:
  * Added shell-script make wrapper
  * Removed Norcroft-specific options from Makefile
  * Added GCC equivalents of inline assembler
  * Force use of our kernel.h with GCC (its own one is incomplete)
  * Workarounds to allow full-fat CLX library to use shared makefiles
Admin:
  Tested by rebuilding the DDE tools

Version 2.02. Tagged as 'CLXLite-2_02'

Detail:
  Testing whether !Depend had been updated was unreliable because
  filestamp_get() and filestamp_now() round in opposite directions.
  Since filestamp_now() was only used by amu, I've changed it to match
  filestamp_get().
Admin:
  Tested using amu - requires additional changes to amu itself.

Version 2.01. Tagged as 'CLXLite-2_01'

Detail:
  The original CLX library was an ad-hoc collection of functions shared
  between the sources for multiple tools. Ownership of the original source
  files is now spread between Castle, ARM, Codemist, AT&T and Alcatel, making
  release a licensing nightmare. However, without at least some of these
  source files it is impossible to build various RISC OS specific tools, so
  making it of little use to release the source code thereof.
  To facilitate the release of the most unique tools, we have therefore
  taken the following steps:
  * Evaluated which source files are untainted by non-Castle ownership
    and released them complete with CVS history. This applies to files named:
      dir elf filestamp hash host libflfmt mapping maxalloc pathmacro re
      symdefs wildcard
  * Done a cleanroom rewrite of other particularly critical files:
      bytesex err prgname wholefls
  * Withheld the remaining source files from release
  * Written a new set of build scripts
  With this cut-down version of CLX, which we're calling CLXLite to avoid
  confusion internally within ROOL (we still need the complete version in
  order to build the C tool suite) it should be possible to release:
    chmod diff find modsqz romlinker squeeze srcbuild unmodsqz xpand
Admin:
  Builds all the above tools, but they are currently untested

Version 2.00. Tagged as 'CLXLite-2_00'

Detail:
  Reinstatement of old CLX library files libflfmt and maxalloc
  Ensures that at least one space follows even really long diassembled opcodes
  Bugfix to floating point rounding
  Various extra defines and structs in h.asdfmt and h.ieeeflt
Admin:
  Presumably used for C 5.53 / 5.54 releases.

Version 1.32. Tagged as 'CLX-1_32'

  ELF header file updated to reflect revision B-01 of ARM's document.
  ELF hash function added.
  Fixed a missing return value in wf_rename.
Detail:
  The err_* functions could not previously handle floating point values
    being passed in the variadic arguments.  This restriction is now
    removed from the library and responsibility placed on the caller to
    ensure that floating point hardware/emulator is present if using FP
    arguments to these functions.
  ARM have released SWS ESPC 0003 B-01 - the ARM ELF specification.  The
    header file elf.h has been updated with the new relocation types as
    defined in that document, except for R_ARM_ALU_PCREL_23_15 which has
    been entered as R_ARM_ALU_PCREL_23_16 as this is an obvious mistake
    in the documentation.
  Added a new source file (elf.c) which contains the ELF hashing function.
Admin:
  Built.
  Required by link 5.26 and later (probably)

Version 1.27. Tagged as 'CLX-1_27'

Detail:
  Build fixes for Unix:

* We now use -I{RISCOS_CLIB_HDRS} -I- to ensure that RISCOS C
   library headers aren't used in preference to system headers.

* INSTALL(1) now used to install the clx library.  This is available
   on both Solaris and Linux systems.

Admin:
  Built on Solaris and on a Linux glibc 2.1.3 system.


Version 1.25. Tagged as 'CLX-1_25'

Detail:
  hash_key returns the key used for a given HashId.  This makes it
    easy to make the associated value of a hash entry be the key itself.
Admin:
  Tested.

Version 1.23. Tagged as 'CLX-1_23'

Detail:
  The linker usually caches object files internally.  This means that
    you cannot use SYMDEFS files embedded inside other files (e.g. ALF
    files).  The new API allows an in-memory file to be processed.
  Several APIs changed to allow a void* parameter to be specified for
    passing to the callback function.
Admin:
  Required by link 5.22 and later.
  Tested in conjunction with link 5.22.

Version 1.22. Tagged as 'CLX-1_22'

  Added the thumb disassembler and symbol mapping.
  Added more functionality to bytesex and symdefs.
Detail:
  The symdefs library code can now identify a file without loading it
    into memory in its entirety - this saves the linker a lot of grief.
    A new API is available to ask CLX whether the file is a symdefs
    file or not and defer loading of the symbols until a later date
    (during the load1 phase where the linker is concerned).
  elf.h makes all the definitions per the ARM ELF specification.  The
    linker requires these definitions (even if TARGET_HAS_ELF is not
    defined).
  Some more fixes to the disassembler.
  bytesex has a new API: bytesex_reverse_auto(flag), where flag is either
    bytesex_WANT_LITTLE_ENDIAN or bytesex_WANT_BIG_ENDIAN.  This relieves
    tools of the need to mess around trying to work out the endianness of
    the host to call bytesex_reverse or not.  (bytesex_reversing can be
    called to find out if reversing is happening or not after the call
    to bytesex_reverse_auto.)
  A new macro has been added to aof.h: rel_II to construct the II field
    of a type 2 AOF relocation.
Admin:
  Required by link 5.19 and later.
  Required by objasm 3.19 and later.

Version 1.20. Tagged as 'CLX-1_20'

  Added hash_destroy.
Detail:
  The pathmacro source file exports a single function for resolving
    RISC OS pathnames on whatever the host system is.  For example, this
    means that provided the environment variable HdrPATH is set to point
    to the appropriate directories, then "Hdr:RISCOS" will be resolved
    to the full pathname that can be passed to fopen et al.
  hash_destroy function added to enable hash tables to be destroyed.
    Each associate value is passed to a supplied callback function to
    permit each value to be freed.  Usually this will be NULL (no action)
    or the address of the library function free unless a private allocator
    has been used by the caller.
Admin:
  Tested on RISC OS and Solaris.

Version 1.19. Tagged as 'CLX-1_19'

Detail:
  Only symbols that have their values updated are output during a
    call to sf_rewrite.
Admin:
  Behaviour wrt deletion of the restrict file and its replacement with
     the real output file needs to be fixed.
  Tested with test program and development version of the linker.

Version 1.17. Tagged as 'CLX-1_17'

Detail:
  The symdefs file format is now supported by CLX.  Functions are
    exported for loading symbols tables, updating symbol values
    and regenerating output files as per the ARM documentation.
Admin:
  Tested with a small test program.
  Tested on Solarix x86 and RISC OS.

Version 1.16. Tagged as 'CLX-1_16'

Detail:
  dem.c and dem.h have been added, so they can now be removed from
    all the tools it infests.
  filestamp.c modified to build on Solaris as well as RISC OS.
Admin:
  Exports VersionNum as CLXVersion to prevent search path problems
    in components which put C:CLX on the include path.
  RISC OS build tested.
  Solaris build tested.

Version 1.15. Tagged as 'CLX-1_15'

Detail:
    Added files wildcard.c and wildcard.h from SrcFiler version.
    Debug code modified slightly to use #ifdef LIB_DEBUGGING instead of
      #if LIB_DEBUGGING and #include "clxdebug.h", to be consistent with
      other code in the CVS version.
    Makefile modified to compile this code and export the header.
Admin:
    Compiled and used to build find.

Version 1.12. Tagged as 'CLX-1_12'

dir.c updated to expect up to 256 characters in object leafnames instead of just 16.  Fixes buffer overflows in !Diff.

Detail:
  Changed size of names to 256, reduced number of entries read at
    once to 8, so dynamic memory usage per directory read increases
    from around 16*16 bytes to 256*8.
Admin:
  Built with new version of diff for testing.

Version 1.11. Tagged as 'CLX-1_11'

Detail:
  filestamp.c wasn't building (at least on 1 platform), adding a
  #include <time.h> fixed it.  Unix makefile now also cleans up the
  *.[ch] symlinks on clean: target now.
Admin:
  Built on Linux x86 platform.

Version 1.10. Tagged as 'CLX-1_10'

Detail:
  * Added dir.c and dir.h from the original CLX library.  Minor change
    required to wholefls.c & .h to get this to compile.  Two macros
    previously privately defined in the wholefls.c are now exported in the
    header.
  * Added StripDepnd call to !MkClean.
Admin:
  * Built on RiscPC.  Dir enumeration code tested on Acorn Diff.

Version 1.09. Tagged as 'CLX-1_09'

  host functions for UNIX corrected.
Detail:
  host.c will now tell UNIX targets that:
    The command to change directory is "cd" and not "dir"
    The directory separator is / and not .
    Home directory synonym is ~ and not &
  filestamp.c functions for UNIX added (were never there!)
    filestamp_now() returns result of time() C library call
    filestamp_get(file) returns st_mtime from stat(file) result
    filestamp_mk_execable does nothing.
    filestamp_ignore_centiseconds does nothing.
Admin:
  Tested on Solaris (x86 and SPARC) and RISC OS.
  Required by Solaris builds of modgen (1.01 and later)
  Required by other UNIX builds which rely on host bits being right!
  This implementation of filestamp_* functions will have severe
    difficulties functioning in an environment which utilises 64-bit
    time_t.

Version 1.08. Tagged as 'CLX-1_08'

Version 1.06. Tagged as 'CLX-1_06'

Added missing source files to ccsolaris/Makefile. Converted some of the source files over to ANSI definitions. Fixed wholefls so it actually compiles on RISC OS.

Version 1.05. Tagged as 'CLX-1_05'

* Makefile uses -ff to strip function names from the code areas.

Version 1.04. Tagged as 'CLX-1_04'
