  kernel/s/k_body, s/initmodule - Escape some dollars contained in strings to avoid warnings from objasm
Admin:
  Resulting binary unchanged


Version 5.83. Retagged as 'RISC_OSLib-5_83'

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:
  clib/s/cl_stub, kernel/s/k_body, s/initmodule - Use OS_ReadSysInfo 6 to look up CLibWord/RISCOSLibWord/CLibCounter location each time it's needed instead of using hardcoded addresses. SWI overhead shouldn't be too bad since the zero page areas are rarely used.
  rlib/c/menu - Fix null pointer access when attempting to clear a submenu pointer via menu_submenu(...,...,NULL)
  s/h_workspc - Remove old local definitions of CLibCounter, RISCOSLibWorkSpace and CLibWorkSpace. Use Hdr:PublicWS instead.
Admin:
  Tested on rev A2 BB-xM


Version 5.60. Tagged as 'RISC_OSLib-5_60'

Detail:
 This changes all the C and assembler includes to be a canoncial Unix format.
 Also match include paths to previous commit for EditIntern/DrawIntern/VerIntern
 Finally, also include some minor type fixes (NULL vs 0)
Admin:
 May be some other paths elsewhere in the source I'm not immediately able to fix.  Will address any issues ASAP, since this is a huge change.

Version 5.54. Not tagged

Detail:
  * Implemented the thread-safety mutex macros for the user mode heap.
  * Created ansilibm, a version of ansilib suitable for building modules.
  * Fixed an overestimation of the size of the workspace passed to
    SharedCLibrary_LibInitModule[APCS_32] by the stubs.
  * Fixed bug in SharedCLibrary_LibInitModule[APCS_32] regarding handling of
    non-reentrant modules - if module code was at a higher address than the
    module data, then all the intervening data would be pointlessly copied
    back over itself with no allowance for volatility.
  * Removed the bsearch source file, since it was only required for APCS-A
    which the library has not supported since the year 2000, and which the
    compiler is now no longer able to build.
Admin:
  ansilibm builds working modules, but thread safety has not been
  extensively tested.

Version 5.47. Tagged as 'RISC_OSLib-5_47'

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'

* Added two new library chunks, 4 and 5, which contain extensions to the kernel and C library respectively. These have no static data associated with them, just being extensions of the stub tables. The reason for this is to minimise wasted space in programs that don't use the C99 facilities; o.stubs is now a library split into 3 pieces - basic kernel and CLib, extra kernel and extra

  CLib; only the bits a program needs get included.

* Previous extensions to the C library stubs revoked - they now stop at _swix;
  all the new C99 functions now live in chunk 4. Anyone using those new
  functions should relink with new stubs and ensure this C library version.

* printf/scanf now support 64-bit types through "ll" and "j" length modifiers.

* Run-time support for VLAs (__rt_allocauto and __rt_freeauto) added. No
  attempt is currently made to clear up on longjmp or to cope with someone
  changing the kernel allocator while a VLA is active. These would be a
  future enhancement.

* Added complete 64-bit run-time support (48 functions) to kernel library;
  these functions are compatible with the ones used by the ARM ADS. Many of
  the simpler functions will not normally be used by the compiler, as it
  will generate inline code. There is scope for improvement by switching
  in MULL and CLZ-using forms of multiply and divide when possible.

* llabs and lldiv added to C library.

* Header files corrected in a few areas, and changed to match the C compiler.
  <stdint.h> and <stdbool.h> now require the compiler to be in C99 mode
  (as detected using __STDC_VERSION__).


Version 5.41. Tagged as 'RISC_OSLib-5_41'

  * snprintf(), vsnprintf(), vfscanf(), vscanf(), vsscanf()
  * hh, j, z and t printf length modifiers (indicating char, intmax_t, size_t
    and ptrdiff_t respectively)
  * Hexadecimal floating-point printing and scanning (%a/%A)
  * %F printf() specifier (upper-case form of %F)
  * Input/output of NaNs and Infinities
  * imaxdiv_t, imaxdiv(), strtoimax(), strtoumax() (simulated through macros)
  * <fenv.h>: feclearexcept(), fegetexceptflag(), feraiseexcept(),
              fesetexceptflag(), fetestexcept(), fegetround(), fesetround(),
              fegetenv(), feholdexcept(), fesetenv(), feupdateenv()
  * FLT_EVAL_METHOD, DECIMAL_DIG
  * hypot(), hypotf(), fabsf(), fdim(), fdimf(), fmax(), fmaxf(), fmin(),
    fminf()
  * INFINITY, NAN, fpclassify(), isfinite(), isinf(), isnan(), isnormal(),
    signbit(), copysign(), copysignf(), nan(), nanf(), nextafter(),
    nextafterf() isgreater(), isgreaterequal(), isless(), islessequal(),
    islessgreater(), isunordered()

This involves adding 36 new entries to the stubs. Current versions of the C
library will not fault client programs with such larger stubs, but will fill
in the extra entries with junk. Programs requiring the new functions will have
to RMEnsure this version of the Shared C Library.

This version of the C library has been fixed so that in future, any extra
unknown stubs entries will be filled in with a branch to zero, rather than
corrupted.

Requires cc 5.41 or later, both to build, and to make use of some of the extra
facilities.


Version 5.37. Tagged as 'RISC_OSLib-5_37'

C library now has a default message for C71 (Calling standard no longer supported), so you get a meaningful message if soft-loading a new version.

No code changes.
