      Update to work with zero page relocation · 14a49538
      Jeffrey Lee authored
        clib/s/cl_stub, kernel/s/k_body, s/initmodule - Use OS_ReadSysInfo 6 to look up CLibWord/RISCOSLibWord/CLibCounter location each time it's needed instead of using hardcoded addresses. SWI overhead shouldn't be too bad since the zero page areas are rarely used.
        rlib/c/menu - Fix null pointer access when attempting to clear a submenu pointer via menu_submenu(...,...,NULL)
        s/h_workspc - Remove old local definitions of CLibCounter, RISCOSLibWorkSpace and CLibWorkSpace. Use Hdr:PublicWS instead.

      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.

      Build process changes · 6bfb6dbc
      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.

      Ben Avison authored
        * 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.
        ansilibm builds working modules, but thread safety has not been
        extensively tested.

      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__).

Hopefully should work faster than the old code too!
