5358278ca1 tai_regalloc.allocation changed to ratype to notify rgobj of register size changes 2004-05-22 23:34:27 +00:00

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

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

daniel
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
    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()
  * writing the intereference graph is now only done with -dradebug2 and
    the created files are now called "igraph.<module_name>"

 2003-07-06 15:00:47 +00:00
Jonas Maebe
b1917a614b * support integer registers that are not managed by newra (ie. don't

    first_supreg..last_supreg)
 2003-07-06 14:45:05 +00:00
peter
b7d99ec934 * paraloc splitted in callerparaloc,calleeparaloc

* added constants for indicating source and destination operands of the
    "move reg,reg" instruction to aasmcpu (and use those in rgobj)
 2003-06-14 14:53:50 +00:00

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,

 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
