      Bugfix to macros in Hdr:CPU.Generic32 · 7a505e55
      Ben Avison authored
      Detail:
        A number of these macros, when build targeting all CPUs (e.g. in disc builds)
        only worked correctly if a register was specified to leave the original
        PSR state in.
      Admin:
        Untested, but no risk to ROM builds.

      Second of a two-part update of HdrSrc. · 726bd695
      Ben Avison authored
      Detail:
        Hdr:System:
        * Hdr:CPU.Arch added to the list of header files included here. This is
          because it's now needed by Hdr:CPU.Generic*.
        Hdr:CPU.Generic*:
        * Reintroduced ARMv2 compatibility to many macros. Should allow a new
          universal boot sequence to be constructed.
        * SCPSR in Generic26 optimised in cases where no PSR bits are preserved.
        * RemovePSRFromReg optimised for 32bit-only builds - becomes a no-op.
        Hdr:Machine.Machine:
        * Reordering of braces so that symbol "HAL" doesn't have to be defined -
          useful for disc builds, which target both HAL and non-HAL machines, so
          the symbol is undefined.
        * Added some comments and an assert about No26bitCode and No32bitCode.
      Admin:
        Update originally from Rob Sprowson, bugfixes and additions and split into
        two parts by me.

      First of a two-part update of Hdr:CPU.Generic* · 154397df
      Ben Avison authored
      Detail:
        Changes split into two parts to make the diffs readable. In this part:
        * Simplified the inclusion of Hdr:Machine.<Machine> - all current builds
          require a new enough version of objasm that the bug with GET directives
          inside conditionals appears to no longer apply.
        * A number of macros used to have large switches of almost-identical code
          depending upon whether an optional register was defined or not - these
          are now simplified by using a local variable to hold the register.
        * RETURNS is no longer wrapped in :LNOT: No26bitCode, since it could still
          be useful for exception return, non-transient callback handlers etc.
          However, its presence is still a warning sign for non-32-bit-compatible
          code, so it emits a warning unless you add an extra argument to indicate
          that you've vetted that the code is 32-bit safe.
        * Operator precedence bug fixed in SCPSR from Generic32 copied across to
          Generic26 (applies if bits to set/clear were given as expressions).
        * Conflicting set and clear bits in SCPSR now produce an error in both
          Generic26 and Generic32 (previously was only a warning in Generic26).
        * Added the same flag bit check in WritePSRc in Generic26 as already
          existed in Generic32.
        * Some comments reformatted for consistency.
        * Uses of mymrs replaced with MRS, and unconditional or flag-only uses of
          mymsr macro replaced with MSR (other ones remain to deal with the
          StrongARM bug).
        * RETURNVC and RETURNVS no longer accept NV condition code.
        * Removed BKPT macro (now implemented natively in objasm).

      Rationalisation of Hdr:Machine · 6b8c37eb
      Ben Avison authored
      Detail:
        * Updated comments in 32, All, All32
        * New Machine for IOMD class
        * Phoebe support removed
        * In Hdr:Machine.Machine:
          + Moved the 4 common switches to the top (No32bitCode; No26bitCode;
            NoUnaligned; StrongARM_MSR_bug).
          + Bracketed non 'All' switches, mid term most of these are actually
            kernel private switches, but the HAL kernel still includes a lot of
            pre HAL code so making it tricky to obsolete them in one pass.
          + Bracketed non 'HAL' switches, pending deletion.
          + Bracketed non 'HAL' STB switches, pending deletion.
          + Deleted unused "NewClockChip", "CDVPoduleIRQs", "OldComboSupport",
             "DoPOSTwithoutPowerOn", "M_Phoebe".
          + Moved "HAL32"; "HAL26"; "ROMSizeOffset" to kernel header.
          + Added some comments.

      Detail:
        * Documented ADFS's and SCSIFS's CMOS use better in Hdr:CMOS.
        * Fixed typo in Hdr:NewErrors that causes asasm to emit a warning.
        * Fixed Hdr:OsBytes so that it doesn't trip up Hdr2H. Also listed hex and
          decimal OS_Byte numbers in comments for ease of reference.
        * Fixed some formatting in Hdr:CMOS and Hdr:NewErrors.

      Added BBC micro compatible error numbers to Hdr:NewErrors · a9f38dbc
      Ben Avison authored
      Detail:
        The result of an investigation of error number usage in filing systems -
        note that there is still a strong correlation between many of these and the
        filing system error blocks. It seemed wise to record them somewhere.

        Tested in a Tungsten ROM build to check for name clashes.

          keep this under the allocations system even though it's highly unlikely

      Add protection against StrongARM conditional MSR CPSR_c bug · 6dfb8d83
      Jeffrey Lee authored
      Detail:
        hdr/Machine/Machine - Add new StrongARM_MSR_bug global that's TRUE when we're targeting a StrongARM-compatible machine type.
        Corrected No26bitCode and No32bitCode comments to say that it's all about whether we're supporting 26/32bit processor modes, not about whether we're targetting 26/32bit only processors
        hdr/CPU/Generic32 - Modify macros to protect against StrongARM MSR bug where appropriate.
      Admin:
        Tested with IOMD softload on StrongARM RiscPC.
        Fixes issue with Maestro crashing due to MSR bug creating a stack imbalance in SoundScheduler.
