3d9713b9c8 * has_single_field() now looks recursively into fields that are aggregate 
types until it finds a non-aggregate type, and then returns "true" if
    that aggregate (record or array) contains one element
  * it now also returns the type of that element directly rather than a
    tfieldvarsym, since we only care about the type and in case of an array
    there is no field

aa6b62cf4c Add new procedure option: po_syscall_has_libsym, 
include this option only of libsym field
 is non NIL.
 Use this option to only write redef of libsym if needed.
 Adapt ppudump source to this new procedure option.

a637fbe596 * moved all g_exception_*() methods to hlcgobj and cleaned them up (no more 
hardcoded registers for the most part)
  + added extra g_exception_discard_reason() that can be called when we only
    want to get rid of the currently pushed exception reason, and don't have
    to load it (so it can do nothing on platforms that don't use push/pop)

4431ba2c08 merged/updated AROS/i386 target to trunk from AROS branch, to support Marcus Sackrow's work on AROS support which will hopefully benefit all Amiga-like targets (classic, MorphOS) on the long run. Compiler only, RTL comes in the next run.

* Better handling of LOC_CREGISTER locations.
  + Support direct compares of constants with references.
  + Optimize away comparison of low dword when its result is constant (cases of "less" and "greater or equal" comparing against a constant with zero low dword).

dc628b8969 * x86: Completely skip instructions that do not exist for target CPU bit width. The existing behavior of writing mnemonics and properties but no encoding allows an invalid instruction to be recognized by assembler reader or even generated by compiler, but it but won't assemble anyway.

92cf25b9a5 * Reworked i386 division by constant optimization to reuse code from powerpc64. The algorithm is slightly different, signed version is one instruction shorter, unsigned one is one instruction longer (typically). The new algorithm is easily scalable for x86_64 target, unlike the old one.

2ee0c8de45 * i386: For integer comparisons with zero, emit "test $-1,%reg" instead of "test %reg,%reg". It is more spilling-friendly, because it transforms into "test $-1,spilltemp" and does not require a register. 
* Improved peephole optimizer to remove these instructions if preceded by flag-setting instruction that operates on same location and followed by conditional jump, and change them back into "test %reg,%reg" otherwise.

d88d644925 + support for FMA intrinsic: if there is no hardware support, the compiler throws an error. 
Currently it is implemented only for x86-CPUs supporting the FMA extension. While it would
  be possible to implement it in software or simulate fma(<single>,<single>,<single>) using
  double operations, it makes no sense in my opinion to do so.
