Jonas Maebe
dc71fc8290 * make sure live_start/end is never a tai_regalloc, as those can be 
removed by the register allocator and thus become invalid. This fixed
    make cycle with -Or for ppc, but I'm not sure what the warning on
    symsym.pas:1663 means. Since the tlocation change, even regular make
    cycle doesn't work anymore though...

eaf46c4fb1 * live_registers must be restored after the spilling store code 
is generate to add correct conflicts for extra temporary registers

f5471aef6e * more spilling rewrites 2004-10-05 20:41:01 +00:00
peter
ee3585f56f * spilling code rewritten for x86. It now used the generic 
spilling routines. Special x86 optimization still needs
    to be added.
  * Spilling fixed when both operands needed to be spilled
  * Cleanup of spilling routine, do_spill_readwritten removed
 2004-10-04 20:46:22 +00:00

649bd81edb * Use a normal pascal set in assign_colours, since it only will contain 
real registers

d2a2aeac9f * supregset_reset clears 8kb of memory. However, it is being called in 
inner loops, see for example colour_registers. According to profile data
    this causes fillchar to be the most time consuming procedure.
    Some modifications done to make it clear less than 8kb of memory each
    call. Divides time spent in fillchar by two, but it still is the no.1
    procedure.

b20d72aa36 * do not remove "allocation,deallocation" pairs, as those are important 
for the optimizer
 2004-04-26 19:57:50 +00:00

Jonas Maebe
71202a141d * taicpu.is_same_reg_move() now gets a regtype parameter so it only 
removes moves of that particular register type. This is necessary so
    we don't remove the live_start instruction of a register before it
    has been processed

90e1ca64f3 * Fixed fast spilling functionality by re-adding the code that initializes 
precoloured nodes to degree 255. I would like to play hangman on the one
    who removed that code.
 2003-09-12 19:07:42 +00:00
florian
8f66389b46 * improved arm code generation 
* move some protected and private field around
  * the temp. register for register parameters/arguments are now released

Jonas Maebe
4f8c390198 * fixed regvars so they work with newra (at least for ppc) 
* fixed some volatile register bugs
  + -dnotranslation option for -dnewra, which causes the registers not to
    be translated from virtual to normal registers. Requires support in
    the assembler writer as well, which is only implemented in aggas/
    agppcgas currently
 2003-08-17 16:59:20 +00:00

daniel
557ac8b02e * Fixed a register allocator bug 
* Figured out why -dnewra generates superfluous "mov reg1,reg2"
    statements: changes in location_force. These moves are now no longer
    constrained so they are optimized away.
 2003-08-03 14:09:50 +00:00
Jonas Maebe
7bc1557f5c * add_edges_used() is now also called for registers allocated with

Jonas Maebe
f67e370ce1 * set inital costs of assigning a variable to a register to 120 for 
non-i386, because the used register must be store to memory at the
    start and loaded again at the end
 2003-05-31 20:31:11 +00:00
Jonas Maebe
0357f71e14 * fixed several regvar related bugs for non-i386. make cycle with -Or now

Jonas Maebe
f433c21ead * use as little different registers on the ppc until newra is released, 
since every used register must be saved

Jonas Maebe
cb279b2029 * changed tt_persistant to tt_persistent :) 
* tempcreatenode now doesn't accept a boolean anymore for persistent

5e7a1e3729 * removed unused units

 2002-04-04 19:05:54 +00:00
peter
5b242f7741 * tlocation,treference update 
* LOC_CONSTANT added for better constant handling
  * secondadd splitted in multiple routines
  * location_force_reg added for loading a location to a register
    of a specified size
  * secondassignment parses now first the right and then the left node
    (this is compatible with Kylix). This saves a lot of push/pop especially
    with string operations
  * adapted some routines to use the new cg methods

7fb55bf4e4 + a_loadfpu_* and a_loadmm_* methods in tcg 
* register allocation is now handled by a class and is mostly processor
    independent (+rgobj.pas and i386/rgcpu.pas)
  * temp allocation is now handled by a class (+tgobj.pas, -i386\tgcpu.pas)
  * some small improvements and fixes to the optimizer
  * some register allocation fixes
  * some fpuvaroffset fixes in the unary minus node
  * push/popusedregisters is now called rg.save/restoreusedregisters and
    (for i386) uses temps instead of push/pop's when using -Op3 (that code is
    also better optimizable)
  * fixed and optimized register saving/restoring for new/dispose nodes
  * LOC_FPU locations now also require their "register" field to be set to
    R_ST, not R_ST0 (the latter is used for LOC_CFPUREGISTER locations only)
  - list field removed of the tnode class because it's not used currently
    and can cause hard-to-find bugs
