      Add C11/C18 library functions · eef62ec8
      ROOL authored
      Detail:
        alloc.c - Add aligned_alloc(). Since softloaded versions of the C library can't rely on OS_Module 24 being available there is a fallback implementation for older kernels.
        stdlib.c - Add quick_exit() and at_quick_exit(). Also fix bug in _Exit; a missing loop pre-decrement led to only checking a single (out of array bounds!) vector.
        time.c - Add timespec_get().
        cl_entry2 - 4 new functions added to the stubs.
        Reduce spare CLib static workspace to absorb the quick_exit() handlers, remove the unused words from armsys.c so they're all accounted for in one space.
      Admin:
        In order that the functions can be defined in the stubs now (despite not having a compiler to support C11/C18) they are enabled when 'DDE' is defined so that C library builds work.

      File handling improvements · 8dcb6880
      Ben Avison authored
      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).

      <ctype.h> * isblank() added. · 8f9cfb8a

                * isprint() now true for non-breaking spaces
      <math.h>  * FP_INFINITY corrected to FP_INFINITE
                * fma(), fmal(), llrint(), llrintf(), llrintl(),

                  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().

      * __assert2() added to support for C99 assert(), which displays function name. · f126a1ab
      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.

      * 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__).
