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 db03785109 Merge pull request #7 from davidgiven/travis 
Use built-in Lua rather than relying on a system one
 2016-10-30 15:59:04 +01:00
David Given 9b6a5e3ae7 Merge from default. 2016-10-30 15:53:26 +01:00
David Given a5990289a9 Don't allow parallel builds in the top-level makefile. 2016-10-30 15:49:39 +01:00
David Given 613821d771 Old versions of make don't support -r. 2016-10-30 14:28:08 +01:00
David Given ca5b6e07bb Properly export symbols. 2016-10-29 23:52:17 +02:00
David Given 8c3670483f Get top working with the PowerPC; use it to eliminate useless branches and 
moves.
 2016-10-29 23:37:11 +02:00
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 e3ebf986e9 More opcodes. 2016-10-29 13:32:09 +02:00
David Given 1ae8b90238 More opcodes. 2016-10-29 12:55:34 +02:00
David Given acaae765af Emit negative constants correctly. 2016-10-29 12:55:21 +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 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.
 2016-10-29 11:57:56 +02:00
David Given bfa65168e2 Don't generate phis if unnecessary (because this breaks the 
critical-edge-splitting guarantee and causes insertion of phi copies to fail).
 2016-10-29 10:55:48 +02:00
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...).
 2016-10-27 23:17:16 +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 be3dece5af Allow emission of strings containing ". 2016-10-27 21:48:46 +02:00
David Given 51bd3ee4dd Fix bug where some phis weren't being inserted when a given variable definition 
needed more than one phi (due to the dominance frontier containing more than
one basic block).
 2016-10-27 21:40:25 +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 a4644dee4d More opcodes. 2016-10-24 12:08:40 +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 b1a3d76d6f Re-re-add the type inference layer, now I know more about how things work. 
Remove that terrible float promotion code.
 2016-10-22 23:04:13 +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 90d0661639 Typo fix. 2016-10-22 00:48:55 +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 d6984d60ac Add parsing support for register aliases. 2016-10-20 21:47:28 +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 ffb1eabf45 Floating point promotion is less buggy. 2016-10-19 23:27:53 +02:00
David Given 34c4cfee8f Merge pull request #6 from kernigh/pr-linuxppc 
PowerPC fixes
 2016-10-19 20:39:10 +02:00
George Koehler 99dee0ad24 Remove f14 to f31 from FREG and FSREG. 
This would have happened later, if f14 to f31 became regvar (like r13
to r31 are now).  I am doing it now because ncg is too slow for rules
"with FREG FREG uses FREG".  We use such rules for adf 8 and other EM
instructions that operate on 2 floats.  Like my last commit cfbc537,
this commit speeds ncg by removing choices for register allocation.
 2016-10-18 21:16:47 -04:00
David Given d5071e7df1 Promote values accessed via NOP. 2016-10-18 23:58:03 +02:00
David Given 5413d47029 '!' tracing is now always emitted; tracing goes to stderr. 2016-10-18 22:32:09 +02:00
David Given 3520704ea8 Add support for floating point constants. 2016-10-18 22:29:42 +02:00
