Detail:
  c/armsys - _kernel_language will return NULL if the PC was outside any known library language block, so make sure to check for that before dereferencing the pointer
Admin:
  Builds, untested


Version 5.86. Tagged as 'RISC_OSLib-5_86'

Add xferrecv_last_ref to get hold of the Wimp message id of the request for a scrap file data save, when the RAM transfer gets no reply. This is useful to allow the data save to be distinguished from a file being dragged to an application, without having to resort to string compares against <wimp$scrap>.
SWIOptions:
 Also add RTC to SWI exports, and remove redundant ones.
armsys.c:
 Treat cmd_string as a pointer.
xferrecv.c/.h/rl_entries:
 New function xferrecv_last_ref.

Version 5.84. Tagged as 'RISC_OSLib-5_84'

Fix for problem passing long command lines via system(), while there are good arguments to leave the threshold at 255, non DDEUtils aware programs get brutally truncated command strings, and since the old threshold of 255 applied when the kernel handled 256 command lines, upping the limit to 1k is no worse than before.
Fix for Edit failing to draw lines of text longer than 192 characters (ticket #350). Several factors were conspiring here: on a mode change the window width in characters wasn't being clamped, whereas user entered limits in the menu were, then the internal buffer ("PAINTBUFSIZE") was too short so lines got truncated, and when larger than 256 got wrapped modulo 256 due to the use of an array of chars. Now set at compile time with BIG_WINDOW_SIZE_LIMIT with a new theoretical maximum of 8192. Currently limited to 480 since it uses stack variables.

In the C library:
 armsys.c: adapt the threshold at which to use DDEUtils based on the kernel version number
 scanf.c: squash a warning
 time.c: mark the table of month lengths as constant so we can claw back 13 words of static workspace without having to change the stubs

In RISC OS lib:
 bbc.c: remove local definitions of some SWI numbers
 template.c: squash a warning
 txt.c: delete Modula-2 support
 txt1.c: compare pointer with NULL not an integer
 txtar.c: introduce BIG_WINDOW_SIZE_LIMIT, rationalise a few sprintf's, mark private functions as static
 txtundo.c/txtedit.c: squash old style function warnings
 txtoptmenu.c: clamp the window width read from Edit$Options properly, delete long disabled code
 txtscrap.c: dead function deleted


Version 5.78. Tagged as 'RISC_OSLib-5_78'

Detail:
  c/armsys - _desktop_report now always caches the error message in the local error block. This avoids the error potentially being overwritten with "Task not known" if TaskManager_TaskNameFromHandle fails.
Admin:
  Tested on Raspberry Pi


Version 5.72. Tagged as 'RISC_OSLib-5_72'

  Ammended time() to match ISO9899 and just return UTC like it says.
  Inlined the single use of _bbctime() macro.
locale.c
  The timezone within a territory can now be specified as part of the setlocale() function.
  This uses a qualifier to the already accepted territory name, for an example see test/tzones.c
  Shock addition of some comments to the locale parsing function.
  To avoid needing to mess about with C library workspace the timezone and territory are encoded internally into 1 word, with 10 bits allowing up to 1024 territories worldwide.
  Ripple through to strftime().
time.c
  localtime() updated to respect locale selection.
test/file,gen_inputs,test64
  Copyright headers added.

Output compared with Windows XP using setlocale versus tzset to shift the program into Pacific time.

Version 5.68. Tagged as 'RISC_OSLib-5_68'

Was being used to conditionalise things which aren't really StrongARM related, now should be read as "support split I+D caches" switch.

Version 5.65. Tagged as 'RISC_OSLib-5_65'

Detail:
  * Added 64-bit file pointer API support, following the LFS spec v1.5
    (see Docs directory). Internally, now uses 64-bit file pointers
    exclusively. For now, the backend still limits you to 4GB-1 files, but
    clients of the C library won't need recompiling again to support larger
    files than this once they use the new API.
  * Fixed a large number of warnings produced in compilation, assembly and
    linking, many of them new and resulting from the improved checks in the
    latest toolchain.
  * Increased the maximum stream buffer size from 16MB to 1GB.
  * Added Hdr:SDFS and Hdr:SDIO to the list of headers used to build swis.h
    if they are present.
Admin:
  Verified that the new 64-bit file pointer buffering code works using a
  ROM build (since the toolchain makes extensive use of reading, writing
  and seeking internally).

Version 5.64. Tagged as 'RISC_OSLib-5_64'

Detail:
  * _kernel_irqs_disabled() is included in ansilib build, now needed for
    ARM 2 SWP replacement in c.alloc
  * _kernel_entrypoint() for ansilib now initialises relocation offsets in
    root stack chunk, necessary if linking with -zm object code
  * system() implementation now calls DDEUtils_FlushCL if starting a
    short command line - necessary in case previous system() call was a
    long command line directed at a DDE-unaware application
Admin:
  Ansilib changes tested, DDE change not expected to cause problems.

Version 5.47. Not tagged

* _Exit() added.
* Lots of new <math.h> functions (acosh, asinh, atanh, exp2, expm1,
  ilogb, log1p, log2, logb, scalbn, scalbln, cbrt, erf, erfc,
  lgamma, tgamma, nexttoward, fmaf). Float and long double forms
  of every function added; long double forms are included as another
  library object in the stubs rather than the shared library, as they
  just branch to the double form.
* Subnormal/NaN/infinity cases in various <math.h> functions improved.
* Added <tgmath.h>.
* Headers brought into line with CC 5.54.
* RMEnsures added to C library initialisation to try to load minimum
  CallASWI, FPEmulator, CLib. No errors reported if load fails.
* A few pointless inter-file dependencies removed to reduce minimum
  size of included ANSILib.

Version 5.46. Tagged as 'RISC_OSLib-5_46'

PCI added to swis.h
alloc.c updated to handle bigger slots (new code merged from ARM libraries)
Various 32-bit fixes for backtracing, and general trap handling.
Polite "Application is not 32-bit compatible" message.
Headers <stdint.h> and <inttypes.h> fixed to work in non-C99 mode.
txt changed to do new-style Delete behaviour

Version 5.44. Tagged as 'RISC_OSLib-5_44'

  Aborts now give standard error messages (Abort on Data Transfer at... etc)
  *ShowRegs now filled in after aborts
  assert(), abort(), "free failed" and standard signal handlers now use Wimp
    error boxes if in the desktop
  Postmortem button on error boxes to view the postmortem

Also, x$multiply, x$divide, __rt_sdiv, x$remainder, x$udivide, __rt_udiv and
x$uremainder optimised.

Version 5.35. Tagged as 'RISC_OSLib-5_35'

* Fixed C library tty so it can output '\b' (backspace).
* Made offsetof() and va_arg() macros work with C++.

Version 5.34. Tagged as 'RISC_OSLib-5_34'

  Another getenv() bug fixed.
Detail:
  stdio.c contains a vastly improved implementation of fwrite.
  hostsys.h declares _terminate_getenv to remove build warnings.
  armsys.c contains fix to getenv() to stop Omni dying.
Admin:
  Tested on desktop machine for over a week without incident, including
    several heavy fwrite users (WebServe, C compiler)
  fwrite change is documented in Doc/fwrite
  getenv() bug is Bugzilla bug #28

Version 5.27. Tagged as 'RISC_OSLib-5_27'

  OS_ReadVarVal.

Detail:
  getenv calls OS_ReadVarVal to read a system variable into a buffer.
  If the buffer is not big enough it increases the size of the buffer by
  256 bytes and tries again.
  However, the first time it was called, it would have no buffer and
  would call OS_ReadVarVal with r2=-1. The PRM says this "may" return an error
  which should be ignored, but if it did not return an error then getenv
  would not allocate a buffer and the call would fail.
  This change allocates a 256 byte buffer before OS_ReadVarVal is called.

Admin:
  Untested.

Version 5.20. Tagged as 'RISC_OSLib-5_20'

  Fixed bug in getenv() relating to macro and numeric system variables.
Detail:
  Uses SYMDEFS file to avoid messing around with generating little text
    files, generating assembler source, assembling it etc.  abssym et al
    are construct as symbol definition template files and then updated
    directly by the linker ready for export.  The linker can use these
    files directly without needing them to be assembled into AOF format.
  Fixed getenv so that it can read macro and numeric variables.  With these
    variable types, R2 does not equal -length of the variable value, so
    trying to obtain a variable with a larger value than any previously
    read variable would fail.  This is now fixed.
  This module will refuse to build without link 5.19 or later.
Admin:
  Requires Library 0.54 or later.

  This component will not build with Library 0.53 or earlier.

Version 5.16. Tagged as 'RISC_OSLib-5_16'

Version 5.06. Tagged as 'RISC_OSLib-5_06'

This is the standard RISC OS convention (cf OS_NewLine) - some apps assume
it when redirecting output.

Version 5.02. Tagged as 'RISC_OSLib-5_02'

StrongARMfudge flag removed.
StrongARM compatibility set according to AMBKernel flag in Hdr:RISCOS
strftime %U and %W specifiers fixed for week 0.

Version 4.89. Tagged as 'RISC_OSLib-4_89'

If a module written in C uses function getenv, buffer space
is allocated in the RMA. This buffer was never freed, leading
to RMA leakage when the module was 'RMKill'ed or 'RMReInit'ed.

Changes

 c.armsys
   added function _terminate_getenv to free the buffer

 c.stdlib
   added flag getenv_finalised to the exit_s structure

   initialised getenv_finalised in function _exit_init

   atexit tests getenv_finalised, calls _terminate_getenv

 s.version
   version string changed to 4.86 (27 Jul 1998)
