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

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.

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>"	2003-07-21 13:32:39 +00:00

Jonas Maebe	80d6905b7b	* fixed my previous completely broken commit. It's not perfect though, ... registers > last_supreg and < max_intreg may still be "translated"	2003-07-06 15:00:47 +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 ... works for ppc	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	2003-05-17 13:30:08 +00:00
