edd42aa42a * moved subsetref/reg and bit_set/test support from cgobj to hlcgobj for
future use by high level code generator targets
   o this in turn required that all a_load*_loc* methods are called via
     hlcg rather than via cg, since a location can be a subsetref/reg and
     and those are no longer handled in tcg
   o that then required moving several force_location_* routines into
     thlcg because they use a_load_loc*, but did not take tdef size
     parameters (which are required by the thlcg a_load_loc* routines)
   o the only practical consequence is that from now on, you have to
     use hlcg.location_force_mem/reg() (fpureg not yet) and
     hlcg.gen_load_loc_cgpara() instead of the removed versions from ncgutil,
     and hlcg.a_load*loc*() instead of cg.a_load*loc* if a subsetref/reg
     might be involved

d84e8adc77 further fix for tw10233 on powerpc(64) platforms:
* do not overwrite left.location.register in second_int_to_bool() but use temp register when converting input value to C style truth values (i.e. 0,-1). With -Or enabled this register will be reused not containing the correct value anymore.

771479e65c * Improved fix for bug #10233 for better Delphi compatibility and efficiency:
- Explicit typecasts like LongBool(byte_value) do not change ordinal value.
  - Explicit typecasts like ByteBool(longint_value) do not change ordinal value and can lead to data loss if longint_value is outside of ByteBool range.
  - Explicit typecasts like ByteBool(LongBool) handle type ranges correctly.
  - Updated test tw10233.pp. It is passed by Delphi as well.

cf235145cb * Fixed a_load_reg_reg for arm.
* Fixed sign/zero-extension in second_int_to_bool for all CPUs. x86 and pppc were not affected by this bug, but I fixed it for all CPUs for consistency.
* cg/tcnvint1 is passed on arm now.

62e66d2a56 * explicit typecasting of any ordinal type to a boolean of the same
size must happen without any mangling of the value (mantis #11027)
  * moved checking for signed-to-unsigned (or vice versa) type
    conversions in assignments from htypechk to ncnv (where there
    was already code for similar checks) and added support for
    bool_to_bool there as well

f36e5411af * split cpu64bit compiler define into
a) cpu64bitaddr, which means that we are generating a compiler which
       will generate code for targets with a 64 bit address space/abi
    b) cpu64bitalu, which means that we are generating a compiler which
       will generate code for a cpu with support for 64 bit integer
       operations (possibly running in a 32 bit address space, depending
       on the cpu64bitaddr define)
   All cpus which had cpu64bit set now have both the above defines set,
   and none of the 32 bit cpus have cpu64bitalu set (and none will
   compile with it currently)
  + pint and puint types, similar to aint/aword (not pword because that
    that conflicts with pword=^word)
  * several changes from aint/aword to pint/pword
  * some changes of tcgsize2size[OS_INT] to sizeof(pint)

8349cde7db * changed byte/word/longbool to be Delphi-compatible (+ similar changes
for qwordbool) + test:
    o assigning true to such a variable now sets them to $ff/$ffff/$ffffffff
    o these types are now all signed
    o converting an integer type to a byte/word/long/qwordbool using an
      explicit type cast keeps the integer's original value stored in the
      bool, instead of forcing it to ord(true)/ord(false)
    (mantis #10233 and #10613, implemented for all architectures, testsuite
     tested for ppc32, sparc and x86)
  * fixed some places where the rtl depended on longbool(true) having the
    value 1
  * extended several boolean tests (and adapted some to no longer assume
    that byte/word/long/qwordbool(true)=1)
  + support for converting to qwordbool in second_int_to_bool for x86, ppc
    and sparc
