b77a51f67d + first somewhat-valid AmigaOS/PowerPC support (no linking yet)

c25aba7592 * cleaned up subsetreg support (put everything in a record) 
* prepared support for elements with arbitrary bit length (as opposed
    to a multiple of 8)

e08aa358fb * removed stb from calculation_target_op0 (stb does not calculate a value 
to store in operand 0)

git-svn-id: trunk@4269 -
 2006-07-20 22:38:26 +00:00
Jonas Maebe
90cacb4cf5 * changed result type of dwarf_reg from byte to shortint to avoid 
warning about comparison which can never be true

a shared library

550626ef34 - Removed need of assembler startup files for wince. Now compiler directly creates .pdata section needed for arm-wince exception handling. 
git-svn-id: trunk@3764 -
 2006-06-02 08:36:25 +00:00

488d8ae766 * improved support for merging two consecutive rlwinm's (now also works 
if both perform a rotation)

git-svn-id: trunk@3759 -
 2006-05-31 20:25:39 +00:00

3a3651a050 + ppc implementations of subsetreg routines 
git-svn-id: trunk@3758 -
 2006-05-31 19:01:08 +00:00
Jonas Maebe
03302dc7c4 * fixed support for macpas & and | operators: they only work on booleans 
now, and always perform short circuit boolean evaluation (also in {$b+})

git-svn-id: trunk@3745 -
 2006-05-30 13:02:36 +00:00

a20f211811 * don't try to reuse registers from left/right, impedes optimal register 
allocation

a3cb1b1523 + support for "exotic" locations in load_left_right() 
git-svn-id: trunk@3556 -
 2006-05-17 19:12:00 +00:00

a387be19a0 + a_call_ref for ppc32 and ppc64 
git-svn-id: trunk@3392 -
 2006-04-30 20:50:37 +00:00
Jonas Maebe
0d77459b9d * added missing masking of upper 24/16 bits on ppc after performing 
add/sub/shl/mul on 8 or 16 bit "registers" + test (tcinvint5)
  * optimized register-register loading of < 32 bit values (removes
    30KB of superfluous extsb/extsh/rlwinm's from compiler+rtl)

git-svn-id: trunk@3207 -
 2006-04-14 13:01:10 +00:00
Jonas Maebe
55a2007321 * fixed skipping of parameter registers for ppc/aix in case a parameter 
has to be passed on the stack before all registesters are used up
  * fixed calculation of stack offsets for ppc/aix abi for small records, 
    arrays and ordinals passed on the stack after all registers are used
  + test for all of the above

c41da1172c * removed wrong comment along with commented-out code 
git-svn-id: trunk@3165 -
 2006-04-07 21:57:30 +00:00
Jonas Maebe
385815beff * fixed offset calculation of first parameter on the stack if there 
were any preceding parameters < 4 bytes

 2006-04-04 12:44:19 +00:00
Jonas Maebe
6c62d6a647 + get_max_value in defutil 
* use a linear cmp list instead of subtractions on ppc if low >=
    low(smallint) and high <= high(word), because a compare does not
    introduce any dependencies (and in those cases using subtractions
    does not save any instructions or bytes either)

ab8f96f4cf * disabled i386 createtempparaloc again because it generates wrong 
code in case of nested function calls with lots of arguments

 2006-03-17 22:01:25 +00:00

8a6ebdf274 - disabled loop unrolling for level 3 optimizations since it only causes 
crashes (and even if it didn't, on its own it mainly causes code
    bloat)
