        A minus sign was missing - this meant that any module built using stubs
        from the last 2 weeks would branch through zero at the end of initialisation.

      File handling improvements · 8dcb6880
      Ben Avison authored
        * 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.
        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).

      Long long multiply bugfix · 3f057115
      Ben Avison authored
        Last revision broke _ll_mullu (the runtime support function for multiplying
        a 64-bit integer by an unsigned 32-bit integer) except for ROM builds that
        target CPUs with the M extension. So in practice, IOMD ROMs and softloadable
        C libraries both exhibited the bug.
        Verified that the compiler will now run against this C library (previously
        it reported many non-sensical errors).

      Fix objasm 4 warnings. Enable (S|U)MULL/CLZ in math code. · a6d65423
      Jeffrey Lee authored
        s/longlong - The code has always had the ability to use CLZ & long multiply instructions, but it's never been enabled. The nonfunctional code to detect the CPU architecture at runtime has been disabled, and instead a fixed configuration is selected at compile time with the help of Hdr:CPU.Arch. Also added lots of ROUT's for safety.
        s/objmacs - Updated push/pop macros to make use of LDR/STR when only one register is to be transferred. This fixes a few objasm 4 warnings and should result in a speed boost where applicable.
        Tested on rev A2 BB-xM.

      Fix alignment fault when reporting the "This file doesn't contain a BASIC program" error · 38fd341c
      Jeffrey Lee authored
        rlib/c/txtedit - Rather than generating a proper error block to send to Wimp_ReportError, txtedit__validbasicfile was just subtracting 4 from the pointer to the error string.
        The resulting address isn't guaranteed to be aligned properly, resulting in an alignment fault on ARMv7 when Wimp_ReportError examines the error number.
        The new code just reuses the 'buff' array to build a temporary error block.
        Fixes alignment fault on beagleboard when attempting to load a detokenized BASIC file into !Edit.

      Improve safety & reliability of callback handling in SharedCLibrary · 96b4a3c3
      Jeffrey Lee authored
        CallBackHandler in kernel.s.k_body now ensures that the stored 'sp' and 'sl' values are word-aligned before attempting to read from 'sl' to verify that it points to a stack chunk. This avoids an exception being triggered in certain situations when alignment exceptions are turned on and a piece of hand-written assembler is using the sl register to store data.
        Further checks should be added to check that 'fp' is valid before calling _kernel_unwind, as _kernel_unwind currently only performs minimal checks that are not always sufficient.
        Tested on rev C2 beagleboard with KinoAmp pre-release.

      Ben Avison authored
        Install rule now takes an optional INSTTYPE switch: if this is set to
        "libraries" then instead of installing the SCL module, we install the
        headers, stubs, ansilib, risc_oslib and overlay manager libraries. This is
        intended primarily for the tools CD disc image.
        The component is also now cleaned in the "clean" phase. Historically, the
        exception made for this component (and OSLib and Desk, both now binary
        imports) was made on the grounds of speed, and this is not such an issue
        these days. Moreover, we need cleaning to take place on desktop disc builds
        because the SCL must be built and installed in both APCS-R and APCS-32
        versions, which requires an intermediate clean.
        Tested in a Tools CD build.

      Build fix · c676e8e6
      Ben Avison authored
        Some users reported problems building the sources if they had other
        installations of perl on their build machine. The build system was using a
        mixture of "perl" and "<Perl$Dir>.perl" to invoke the interpreter, and
        sometimes but not always using "do" to expand system variables on the
        command line. This has now been standardised to use "do <Perl$Dir>.perl in
        all cases, and where possible, to use the makefile macro ${PERL}.
        Checked that a Tungsten build still works on a build machine with no other
        perl installation. "perl" was aliased to an error to ensure it wasn't used.

        * 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.
