David Given 941072e0d7 Add, I hope, patterns for fmsub, fnmadd, and fnmsub (also float versions). 2016-10-31 22:36:54 +01:00
David Given 44f0cea6ca Also use fmadd for single-precision floats. 2016-10-31 19:55:16 +01:00
David Given 064d1a5d5d Use fmadd for multiply-and-add instructions. 2016-10-31 19:52:17 +01:00
David Given a8c4dac67c Merge from default (merging in George Koehler's PowerPC changes). 2016-10-29 22:40:40 +02:00
David Given a311e61360 Add support for preserved registers. 2016-10-29 20:22:44 +02:00
David Given 1ae8b90238 More opcodes. 2016-10-29 12:55:34 +02:00
David Given 61349389fb More opcodes. sti can now cope with non-standard sizes (really need a better 
fix for this). Hack in crude support for mismatched stack pushes and pops (ints
vs longs).
 2016-10-29 12:48:05 +02:00
David Given 2cc2c0ae98 Lots more opcodes. Rearrange the stack layout so that fp->ab is a fixed value 
(needed for CHAINFP and FPTOAB). Wire up lfrs to calls via a phi when
necessary, to allow call-bra-lfr chains.
 2016-10-29 11:57:56 +02:00
David Given 81525c0f2c Swaps work (at least for registers). More opcodes. Rearrange the stack layout 
so we can always trivially find fp, which lets CHAINFP work.
 2016-10-27 21:50:58 +02:00
David Given 9977ce841a Remove the bytes1, bytes2, bytes4, bytes8 attributes; remove the concept of a 
register 'type'; now use int/float/long/double throughout to identify
registers. Lots of register allocator tweaks and table bugfixes --- we now get
through the dreading Mathlib.mod!
 2016-10-25 23:04:20 +02:00
David Given 45a7f2e993 Phi copies are now inserted as part of type inference. More opcodes. 2016-10-24 22:14:08 +02:00
David Given 111c13e253 More opcodes. 2016-10-24 20:15:22 +02:00
David Given b22780c075 More opcodes, including the difficult and fairly stupid los/sts. 2016-10-23 22:24:08 +02:00
David Given abd0cedd61 Massive change to how IR types are handled; we use the type code for matching 
rather than the size. Much cleaner and simpler.
 2016-10-23 21:54:14 +02:00
David Given 11b0bc1055 More opcodes. 2016-10-22 20:32:51 +02:00
David Given 2d52b1fdaa Remove GETRET; values are now returned directly by CALL. Fix a bug in 
convertstackops which was resulting in duplicate IR groups.
 2016-10-22 12:13:57 +02:00
David Given ceb938fb3c More opcodes. 2016-10-22 11:26:28 +02:00
David Given 7ae888b754 Hacky workaround the way the Modula-2 compiler generates non-standard sized 
loads and saves. More opcodes; simplified table using macros.
 2016-10-22 10:48:22 +02:00
David Given f851ab83af Better (and more correct) floating point conversions; fif; various new opcodes. 2016-10-22 00:48:26 +02:00
David Given d535be87b1 fef4 and fef8 is now cleaner, albeit slower; add some more register alias 
stuff.
 2016-10-22 00:02:15 +02:00
David Given 4db402f229 Add (pretty crummy) support for register aliases and static pairs of registers. 
We should have enough functionality now for rather buggy 8-bit ints and
doubles. Rework the table and the platform.c to match.
 2016-10-21 23:31:00 +02:00
David Given e4fec71f9c Lots more opcodes; better eviction behaviour; better register moves. Lots more 
PowerPC stuff (some working).
 2016-10-19 23:29:05 +02:00
David Given 938fb8c2fc Lots more opcodes. 2016-10-18 00:31:26 +02:00
David Given 5f0164db62 Bolt mcg into the PowerPC backend. It doesn't build yet, but it is generating 
*some* code.
 2016-10-17 00:06:06 +02:00
Renamed from mach/proto/mcg/table (Browse further)
