      Changes required for Customer W. · d08d7612
      Ben Avison authored
      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.

      Kevin Bracey authored
      * _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.

      Misc changes. · aa313346
      Ben Avison authored
      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.

      Kevin Bracey authored
      * 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__).

      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.

      * Optimised hypot[f].

        * 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)

        * Input/output of NaNs and Infinities
        * imaxdiv_t, imaxdiv(), strtoimax(), strtoumax() (simulated through macros)

                    fesetexceptflag(), fetestexcept(), fegetround(), fesetround(),
                    fegetenv(), feholdexcept(), fesetenv(), feupdateenv()

          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.

      Fix for strcmp(). · 9d5bf66a
      Stewart Brodie authored
        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.

      Improved abort handling · c31e0d58
      Dan Ellis authored
      Detail:
        * One check for 26-bit mode wan't being made, leading to the runtime reporting
          'Uncaught trap:' when a trap should have been catching the abort.  This
          prevented signal handlers from trapping some aborts.
        * When an abort was occuring in SVC mode, the stack wasn't being flattened,
          resulting in all sorts of nasty things when you tried to carry on from a
          signal handler (probably the main reason why you ever see 'No stack for trap
          handler'). SVC and undefined stacks are now flattened.  Further work should
          be done to restore the state of the OS after an abort, but this probably
          requires a new OS call to tidy itself up adequately.

        Built 26-bit versions of the library with new 32-bit compatible entry points and checked abort handling with both sharedclibrary and ansilib.

      Changed getenv to ensure it always allocates a buffer before calling · 9076880f
      Paul Skirrow authored
        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.

          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.
