David Given d2c14ca44f Precisely one stack hreg gets allocated for each vreg/congruence group for
eviction; this prevents us from having to worry about moving values from stack
slot to stack slot, which is hard.

David Given 5208e5f751 Yet another OB1 stack format fix. 2016-11-19 10:42:22 +01:00
David Given 86c832ef86 Put saved registers in *actually* the write place. I hope. 2016-11-15 21:54:15 +01:00
David Given b5c1d622f5 Rework the way stack frames are laid out to be simpler and, hopefully, more
correct. Saved registers are now placed in what may be the right place.

David Given 68419da235 Actually, the locals need to go above the spills and saved regs, so fp == lb. 2016-10-29 12:00:33 +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.

David Given 658db4ba71 Mangle label names (turns out that the ACK assembler can't really cope with
labels that are the same name as instructions...).

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.

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 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 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.

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.
