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

8fb3536f6e * simple regvar support, not yet finished 2004-09-26 17:45:29 +00:00

65c3ba277c * ungetregister is now only used for cpuregisters, renamed to 
ungetcpuregister
  * renamed (get|unget)explicitregister(s) to ..cpuregister
  * removed location-release/reference_release

daniel
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
peter
3a5717c1b7 * rewrote add_to_movelist, it now uses a field to store the number 
of allocated entries. Also made it using less hardcoded values

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

      300 kb memory in make cycle)
    * Trgobj.combine hand-optimized (still too slow)

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.

8f66389b46 * improved arm code generation 
* move some protected and private field around
  * the temp. register for register parameters/arguments are now released
    before the move to the parameter register is done. This improves
    the code in a lot of cases.

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
7d3bfaaed4 * Precoloured nodes now have an infinite degree approached with 255,

 2003-08-09 18:56:54 +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 
getexplicitregisterint()

    the created files are now called "igraph.<module_name>"
 2003-07-21 13:32:39 +00:00

 2003-07-06 15:00:47 +00:00
Jonas Maebe
b1917a614b * support integer registers that are not managed by newra (ie. don't 
translate register numbers that fall outside the range
    first_supreg..last_supreg)
 2003-07-06 14:45:05 +00:00

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

 2003-05-30 18:55:21 +00:00
Jonas Maebe
f433c21ead * use as little different registers on the ppc until newra is released, 
since every used register must be saved
 2003-05-30 12:36:13 +00:00
Jonas Maebe
cb279b2029 * changed tt_persistant to tt_persistent :) 
* tempcreatenode now doesn't accept a boolean anymore for persistent
    temps, but a ttemptype, so you can also create ansistring temps etc
