a23630260b + "weakexternal" support for imported procedures and variables. 
the syntax is exactly the same as for "external", except for
    the keyword. It is currently only active for Darwin targets.
    It should also work at least for Linux targets, but only with
    the GNU assembler (which is why it is not activated there)
  + test for this functionality

+ write the header for non-pic darwin/arm call stubs properly in aggas
  * r9 is not available for general use on darwin/arm according to the llvm
    code generator

ec943198fd * Properly fill treference.alignment when variable is loaded by tcgloadnode. It allows code generator to insert unaligned handling if needed. 
* Improved generic a_load_ref_reg_unaligned if ref alignment is 2.
* Improved unaligned load/store of register for ARM.
* It fixes passing records by value on ARM.
+ New test.

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.

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

e815b923d5 * a_loadfpu_* gets two size parameters: fromsize and tosize 
* fixed downsizing the precision of floating point values
  * floating point constants are now treated using only the minimal
    precision required (e.g. 2.0 is now a single, 1.1 extended etc)
    (Delphi compatible)
