Add, I hope, patterns for fmsub, fnmadd, and fnmsub (also float versions).

Also use fmadd for single-precision floats.

Use fmadd for multiply-and-add instructions.

Merge from default (merging in George Koehler's PowerPC changes).

Add support for preserved registers.

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).

Actually, the locals need to go above the spills and saved regs, so fp == lb.

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.

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

Swaps work (at least for registers). More opcodes. Rearrange the stack layout
...
so we can always trivially find fp, which lets CHAINFP work.

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!

Phi copies are now inserted as part of type inference. More opcodes.

Massive change to how IR types are handled; we use the type code for matching
...
rather than the size. Much cleaner and simpler.

Remove GETRET; values are now returned directly by CALL. Fix a bug in
...
convertstackops which was resulting in duplicate IR groups.

Hacky workaround the way the Modula-2 compiler generates non-standard sized
...
loads and saves. More opcodes; simplified table using macros.

Better (and more correct) floating point conversions; fif; various new opcodes.

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.

Lots more opcodes; better eviction behaviour; better register moves. Lots more
...
PowerPC stuff (some working).

Bolt mcg into the PowerPC backend. It doesn't build yet, but it is generating
...
*some* code.
