GitLab

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:
  Parts of RISCOS_Lib use non-standard paths that only really work on native RISC OS compilitation.
  This moves the relevant files into a more normalized dir.h.file format.
 Admin:
  Not tested yet.  #include path changes to follow.

Version 5.54. Not tagged

Detail:
  Added terminating null to clib messages file for tokens C53, C36, C37, C66,
  C70
  appears lost a while ago .. error in field suggested need for this.
  examination of r0 3.7 etc clib messages file showed NULLs here.. believe
  they are the only messages in clib that can emerge through a printf.. and
  this need a null terminator.
Admin:
  Not tested

Version 5.53. Not tagged

* Improved stdio to allocate extra FILE objects beyond the static array of 16. Number of open files now only limited by memory and the OS.

* FOPEN_MAX in <stdio.h> increased from 8 to 16 to reflect reality.
* Minor corrections to comments in <stdio.h>.
* Library shutdown tidied for modules. In particular, shutdown of I/O was
  broken for modules which had been entered as applications.

Version 5.53. Tagged as 'RISC_OSLib-5_53'

Version 5.52. Tagged as 'RISC_OSLib-5_52'

* clib.rom_link_v doesn't seem to have been kept in step with the changes
  to srcbuild as part of the cross-compilation work: it is no longer the
  job of the verbatim rom link makefie fragment to provide a rom_link rule.
  An appropriate alternative set of forwarding rules have been implemented
  instead.
* clib.rom_link_v was never taught about the new C99 library chunks, and the
  relevant s files weren't being exported in the BBE phase either.

Retagged since this won't affect code generation for existing builds.

Detail:
  * Fixed signed pointer comparison: most top-bit-set pointers passed to
    _kernel_raise_error() were being translated into "Exit called"
  * Stack extension is now permitted in SYS mode; includes support in longjmp()
Admin:
  Verified that stack extension works.

Version 5.51. Tagged as 'RISC_OSLib-5_51'

Version 5.50. Tagged as 'RISC_OSLib-5_50'

          * isprint() now true for non-breaking spaces
<math.h>  * FP_INFINITY corrected to FP_INFINITE
          * fma(), fmal(), llrint(), llrintf(), llrintl(),
            llround(), llroundf(), llroundl(),
            remquo(), remquof(), remquol() added.
          * added inlining for remainder() and fmaf() and various
            float functions.
          * math_errhandling removed pending overhaul - it was misleading.
          * expm1() and log1p() now provide decent (< 1 ulp) accuracy,
            rather than only being marginally better than exp(x)-1 and
            log(1+x).
          * new version of copysign() with standard calling conventions.
          * some C99 functions changed to use infinity/NaNs and exceptions
            for error handling - see comments in header file about the
            changes in progress.
<stdio.h>  * output from %a now correctly rounded
<stdlib.h> * strtof() and strtold() added.
<string.h> * strerror() no longer clears _kernel_last_oserror().

Version 5.49. Tagged as 'RISC_OSLib-5_49'

Detail:
  * No longer uses aasm to build h.swis.
  * (Only) compatible with new C compilers: assumes const static data is
    placed in separate read-only areas, and suitable command-line switch
    is used to ensure that library static data is never placed in a zero-
    init area.
  * Stack extension code now thread-safe.
  * Heap thread-safety code (in clib) now uses SWP instruction test results
    from stack extension code (in kernel) - as a side effect, the exported
    symbol _swp_available now exists, if you need to use it elsewhere.
  * Slightly closer to having top-bit-set heap addresses working.
Admin:
  Tested in a Tungsten build, and with Customer W's test suite.

Version 5.48. Tagged as 'RISC_OSLib-5_48'

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

Retagged as 'RISC_OSLib-5_47'

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'

* _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'

Added atoll, strtoll, strtoull, strtoimax, strtoumax, imaxabs and imaxdiv functions to the standard C library.

Version 5.45. Tagged as 'RISC_OSLib-5_45'

Detail:
  * Improved lookup of application Sprites file: uses Wimp_Extend 13 (in
    Wimps that support it) to work out the appropriate resolution suffix,
    and prefixes with "<Wimp$IconTheme>" to allow a future Theme Manager
    to operate.
  * Preserves attributes of any existing file when saving sprite or text
    files.
  * Changed two null menu handles from 0 to (doucmented) -1. Despite the
    fact that the Wimp is actually happy with 0 as a null handle here,
    this was reported as a fault.
  * Changed rlib.c.version to use VersionNum, deleted thereby-obsoleted
    rlib.h.VerIntern.version file. Not that rlib.c.version seems to be used
    at the moment.
  * Added Kevin's additions to the test directory.
Admin:
  Tested briefly.

Version 5.44. Not tagged

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'

Detail:
  Fixed a stack imbalance in _memcpy that's been there since 32-bitting.
Admin:
  Not tested yet.

Version 5.43. Tagged as 'RISC_OSLib-5_43'

Detail:
  This version now builds with cc-5_45. Note: it has not been verified as
  actually functioning correctly.
Admin:
  Tested in DSL Baseline build.

Version 5.42. Tagged as 'RISC_OSLib-5_42'

* 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-ti...

Created cleanroom implementation of 64-bit integer support for licencing reasons. Tested fairly thoroughly (in fact, this testing showed up a bug in the old code which unbalanced the stack for 50% of cases where you divided a negative long long by 10). Hopefully should work faster than the old code too!

Reapplied all relevant old tags.

Real commit date 2008-03-18.

Version 5.40. Tagged as 'RISC_OSLib-5_40'

* Added C99 functions floorf, ceilf, [l]rint[f], trunc[f], [l]round[f], nearbyint[f] and remainder[f].

* Added macros (only) for sinf, cosf, atanf.
* Requires cc 5.43

Version 5.39. Tagged as 'RISC_OSLib-5_39'

* Added C99 extensions to strftime(). All basic specifiers supported, but "E" and "O" modifiers ignored.

* strftime specifiers %c, %X and %x for "C" locale changed to match C99.
* Optimised hypot[f].
* Missing hypotf() declaration added to <math.h>.
* Fixed Shared C Library - inadvertent change to static data size meant it was
  incompatible with the stubs.

Version 5.38. Tagged as 'RISC_OSLib-5_38'

  * 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...

Version 5.36. Tagged as 'RISC_OSLib-5_36'

  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'

* 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'

Detail:
  strxfrm was passing the buffers to the Territory module SWI the wrong
    way around so Territory_TransformString copied the destination over
    the source rather than vice versa!
Admin:
  Reported by <mailto:ian.foster@gps.tandb.co.uk>
  Fixes Bugzilla bug #4375


Version 5.33. Tagged as 'RISC_OSLib-5_33'

  Initialised so_far in stdio.c to remove compiler warning.
Admin:
  Built.  strcmptest() still indicates that strcmp() is working OK!

Version 5.32. Tagged as 'RISC_OSLib-5_32'

Detail:
  This alternate implementation returned non-zero for equal strings,
    because the tidyup routine failed to stop examining the differing
    words when it found matching zero bytes.
Admin:
  Tested in softload C library, and in Lazarus ROM image.  strcmp()
    appears to be working per spec now.

Version 5.31. Tagged as 'RISC_OSLib-5_31'

Detail:
  The file no longer exists as the UROM definition is passed on the command
    line now.
Admin:
  5.29 wouldn't build because of the missing file - didn't catch it during
    testing for some reason :-(

Version 5.30. Tagged as 'RISC_OSLib-5_30'

  Fix for RISC_OSLib res() function.
Detail:
  Version 4.89 featured an improved strcmp() routine that didn't actually
    work properly (bug #4085).  The return values had the wrong sign if this
    optimised code was used and the string contained top-bit set chars.
  Removed that rlib.s.asmdefs hack as the comment in the makefile suggested.
    Nothing needs it any more as the assembler sources that require it now
    get via a -PD argument.
  res_ prefix function was still wrong as it failed to detect valid but wrong
    filenames, hence the "Make$Path not defined" errors in the latest tools
    release.
Admin:
  Fixes Bugzilla bug #4085
  Should fix BaseSW's build problems too.

Version 5.29. Tagged as 'RISC_OSLib-5_29'

  Module library builds of RISC_OSLib are exported during export_libs
Detail:
  Ever since res_findname was altered to use <appname>:<resourcename> as
    the filename, the !C++ tool has been broken, because C++:Messages
    returns a different error to "not found" when you try to open it (it
    says it is an invalid filename).  This error is now caught explicitly
    and res_findname falls back to using <appname$Dir>.<resourcename>
    like it did before.
Admin:
  Required by FrontEnd 1.21 or later.
  Required by !C++ (c++cmd-3_17 or later to function correctly)

Version 5.28. Tagged as 'RISC_OSLib-5_28'

  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
