      Cross-compilation support · a3bda86e
      Ben Avison authored
      * GNUmakefile: add translation of Makefile to GNU make / cross-compilation
        requirements (this component is too non-standard to make much use of the
        shared makefiles)
      * Makefile: comment out rules for objects that aren't used for any targets,
        for clarity; don't clean files that are never created
      * Various: change to using OS-agnostic filename path syntax
      * Various: ensure case matches for filename paths (don't assume host filing
        system is case-agnostic)

      [535] fminf(x,y) / fmaxf(x,y) corrupt result for equal non-zero parameters · ebee6f7d
      Stuart Swales authored
        fminf(x,y) / fmaxf(x,y) corrupted the result when x==y and x!=0.0 due to
        ANDing/ORRing a single precision register with the high word of a double
        precision register pair when fixing up signs for mixed +/- 0 parameters
        in an analogous fashion to fmax/fmin (which are correct).

      Enable modulewrapped applications to use ResGen · 073ebc25
      Ben Avison authored
      This utilises a weak symbol import so that if the symbol `Resources` resolves
      at link time, it is called to discover the address of the resource file data
      block(s) to be installed in ResourceFS. If this fails, it drops back to using
      the `s.ResFiles` source file as previously, thereby ensuring compatibility
      with components that have not yet been converted to use ResGen.
      Since `Resources` is the default area name (and thus discovery function name)
      used for ResGen in the shared makefiles, this makes it as simple as possible
      to utilise it.

      Adjust 26 vs. 32 bit mode checks · fa89c230
      Jeffrey Lee authored
      As noted in https://www.riscosopen.org/forum/forums/9/topics/15359, MRS
      instructions which are executed in user mode may return unknown values
      for the CPSR E, A, I, F and M fields on ARMv8 CPUs. At the moment the
      only observed deviation from normal behaviour is that CPUs which lack
      AArch32 privileged-mode support may return zero for the fields. This was
      found to confuse some 26 vs. 32 bit mode checks in CLib.
      Clearly we're a long way away from having a version of RISC OS which can
      run on a CPU that lacks AArch32 privileged mode support, but we can
      still try and make sure user-mode applications are compatible with them.
      So this change adjusts the mode checks in the stubs and overlay manager
      so that programs linked with them should function correctly (TEQ is now
      used instead of MRS)
      Note that once we do start porting RISC OS to one of the troublesome
      CPUs, there are many more potentially troublesome MRS's within the
      module code that will need adjusting, especially if CPUs start returning
      values other than zero.

      txtar: Support extended scroll requests · d3688b4c
      Jeffrey Lee authored
      Use extended scroll requests to handle mouse wheel scrolling, to avoid
      the "thumbing" code getting confused and thinking the user is dragging
      the scrollbar (the "thumbing" mode of scrolling isn't desirable for the
      mouse wheel, because it largely ignores the requested scroll distance)
      This change allows Edit & SrcEdit (and anything else using txtar) to
      handle the scroll wheel better, now that the WindowScroll module is
      controlling things.

      Fix switch to wrong mode in AbortFindHandler · ae6fe48b

      Add C11/C18 library functions · eef62ec8
      ROOL authored
        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.
        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.

      Add fopen's exclusive mode · 68fc9d43
      ROOL authored
        Remove undocumented 't' mode which forcibly timestamped files, since other operating systems use this to denote a text file (as opposed to 'b' binary mode).
        Add 'x' mode per ISO9899:2018
        * only applies to 'w' mode files (not 'r' or 'a')
        * file must not exist prior to creation
        * beyond that we rely on RISC OS' policy of only allowing a file to be opened once for writing as our exclusivity
        Also fix bug in check for 'Protected disc' error, which only trigged for fsnumber_ADFS (8).
        Tested in a ROM build with a simple test harness.

      Build fix · 20984a33
      ROOL authored
        Add missing function draw_create_diag() to the ROM version of RISC_OSLib, required by Paint-2_24 and later.
        To keep ROM footprint to a minimum, export only that function; this also avoids adding static workspace and needing to increase RlibSpace.

      Various fixes · a8f233bb
      Robert Sprowson authored
      colourtran.c: Swap round arg names to colourtran_colournumbertoGCOL to match prototype.
      txtar.c: Avoid incorrect use of strncat buffer limit, and possible unterminated string after strncpy, by reexpressing using snprintf.
      txtedit.c: Avoid incorrect use of strncat buffer limit by reexpressing using snprintf. Avoid potential NULL pointer dereference by moving the filename copy inside the 'if' which confirms it's non-NULL.
      txtfind.c: Remove repeated check of repls being valid. Free repls on error. Free pat on error.
      xfersend.c: Fix potential out of bounds array access (of leaf[]) if the leafname length exceeds the space in the Wimp message.
      Found by cppcheck static analysis.
      txtopt.c/h: Sprinkle in some consts.
      event.c: Open menu at the Style Guide approved offset of 64.
      xfersend.c: Remove redundant check of xfersend__filename being NULL in xfersend__suggest_leaf() as all paths leading to it being called ensure the allocation exists (also, it would have strcpy'd garbage due to malloc not clear...
