      When multiple CPU architectures are supported, allow dynamically linked... · f3f167bc
      Jeffrey Lee authored
      When multiple CPU architectures are supported, allow dynamically linked clients to be given optimal versions of routines where possible
      
      Detail:
        This set of changes adds support for representing architecture-specific variants of routines within the export tables which the shared C library uses to fill in the client's stubs.
        This allows builds of the module which target multiple architectures (e.g. IOMD, Raspberry Pi, or softloads) to offer the most optimal versions of routines to clients wherever multiple variants exist.
        If only one architecture is supported, only one version of each routine will be built, and no variant tables will be generated.
        Currently routine selection for staticly linked clients isn't supported - staticly linked targets will only use the most backwards-compatible version of the routines, as before. Also not all routines are catered for yet (e.g. _ll_udiv)
        File changes:
        - s/h_common - New file containing macros used during variant table construction
        - Makefile - Set SHARED_C_LIBRARY to {TRUE} for SCL builds of assembler code, as per the SHARED_C_LIBRARY #define
        - kernel/s/k_body, s/longlong - For routines which have multiple variants available for the target architectures, build all variants, and generate variant table entries using the new RoutineVariant macro. This has required some reordering of the different variants to make sure that when both versions are built, the most backwards-compatible one will be first (and thus will be called by staticly linked clients)
        - s/h_modmacro - "Entry" macro (when building SCL export tables) changed to use DCD instead of B, to allow byte-aligned symbols to be represented (low bits of symbol address is now used as 'is a variant table' flag)
        - s/initmodule - Client stub initialisation rewritten to take into account the B -> DCD change, and to detect and evaluate variant entries
        - clib/s/cl_entries, kernel/s/k_entries, kernel/s/k_entries2 - Update library entry tables to reference the variant forms of routines where relevant

      Add C99 standard headers wchar.h and wctype.h · 3ed0fb98
      Ben Avison authored
      Detail:
        These were previously languishing in the C compiler sources, but they
        belong in the C library. Note however that the library does not implement
        the functions described in these headers at the present time, so any
        attempt to use them will result in link-time errors.

      Unbreak stdio.h for C90 mode · 83945ac3
      Ben Avison authored
      Detail:
        Large file support made use of long longs in various definitions. These
        were switched out in PCC mode, but no allowances were made for the fact
        that C90 doesn't define long long either.
        Remember that to force cc to use non-builtin standard headers, you need
        to point at these using the -j switch (e.g. -jC:). The only version of
        cc which featured the C90-incompatible stdio.h was 5.70.
      Admin:
        Checked that the header now works when included in -pcc, -c90 and -c99 modes.

      Merged in a fix to <math.h> from C compiler · 9fe4fc44

      Detail:
        This change was first applied to the inbuilt headers in the C compiler at
        version 5.59 (07 Apr 2005), but was accidentally not copied into the
        RISC_OSLib version of math.h. Fortunately, this would only have affected
        anyone compiling software with the -jC: switch.

        Untested, but should be a safe change.

      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).

      Ben Avison authored
      * 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

        An appropriate alternative set of forwarding rules have been implemented

          from stack extension code (in kernel) - as a side effect, the exported
          symbol _swp_available now exists, if you need to use it elsewhere.

      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__).

      * 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.

      Added the following C99 features: · f464cdae
      Kevin Bracey authored
        * 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.

      Abort and error handling massively overhauled: · 350370aa
      Kevin Bracey authored
        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.

      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.
      Admin:
        Fixes Bugzilla bug #4085
        Should fix BaseSW's build problems too.

      BBE support added. · 0f6d9975
      Stewart Brodie authored
      Detail:
        The BBE export rules for this component are fairly complex.  The rom_link
          bbe rule is overridden in its entirety by clib.rom_link_v as the symbol
          definitions need to be generated and exported during the rom_link phase.
      Admin:
        Tested in BBE build; does not affect other builds.
