Use a better NOT; and after remembering that PowerPC bit numbers are all
...
backwards in the documentation, rewrote IFEQ/IFLT/IFLE to actually work.
Probably. Thanks to the B test suite for spotting this.

Better handling of float conversions; more tests; converting to unsigned ints
...
works now.

cif8 and cuf8 work now. More tests.

Made csa and csb work with mcg; adjust the libem functions and the
...
corresponding invocation in the ncg table so the same helpers can be used for
both mcg and ncg. Add a new IR opcode, FARJUMP, which jumps to a helper
function but saves volatile registers.

Put saved registers in *actually* the write place. I hope.

Update the table to return call output values in the right registers. Fix the
...
register allocator so the corrupted registers only apply to throughs
(otherwise, you can't put output registers in corrupted registers).

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.

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.

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.
2016-10-29 12:00:33 +02:00

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...).

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.

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.

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.

fef4 and fef8 is now cleaner, albeit slower; add some more register alias

stuff.

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.

*some* code.
