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, ... like they should.	2003-08-17 14:32:48 +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>"	2003-07-21 13:32:39 +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	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
