 2006-01-05 04:48:15 +00:00
Andrew Lenharth 6bec63aac9 Move brcond over and fix some imm patterns. This may be the last change before changing the default alpha isel. 
llvm-svn: 25057
 2006-01-01 22:16:14 +00:00
Andrew Lenharth 60ab61fcfc improve constant loading. Still sucks, but oh well 
llvm-svn: 25047
 2005-12-30 02:30:02 +00:00
Andrew Lenharth 50d9caf6a4 let us get some do what I meant not what I said stuff checked in. You would think the alpha backend would be 64bit clean 
llvm-svn: 25040

Andrew Lenharth 962dcbd572 Fix alpha regressions. 
llvm-svn: 25025
 2005-12-27 03:53:58 +00:00
Evan Cheng 14c53b45f5 Added field noResults to Instruction. 
Currently tblgen cannot tell which operands in the operand list are results so
it assumes the first one is a result. This is bad. Ideally we would fix this
by separating results from inputs, e.g. (res R32:$dst),
(ops R32:$src1, R32:$src2). But that's a more distruptive change. Adding
'let noResults = 1' is the workaround to tell tblgen that the instruction does
not produces a result. It works for now since tblgen does not support
instructions which produce multiple results.

 2005-12-26 09:11:45 +00:00
Andrew Lenharth f520093eb3 add br pattern, unify JSR and BSR ISel instrs, and add BSR support for DAG 
llvm-svn: 25011
 2005-12-25 17:36:48 +00:00
Andrew Lenharth 0fce613eff All that just to lower div and rem 
llvm-svn: 25008
 2005-12-25 01:34:27 +00:00
Andrew Lenharth 5b18ed9e60 All addressing modes are now exposed. The only remaining relocated forms 
are for function prologue.

TODO: move external symbols over to using RelLit.
    : have a pattern that matches constpool|globaladdr
    : have a pattern that matches (add x imm) -> x, imm or (...) -> ..., 0
llvm-svn: 25003
 2005-12-24 08:29:32 +00:00
Andrew Lenharth b9aaea3564 Unify the patterns for loads and stores. Now offset addressing should be 
supported.  This almost completes memory operations.

llvm-svn: 25002
 2005-12-24 07:34:33 +00:00
Andrew Lenharth 4621488965 Let's see if we can break things. 
Lower GOT relative addresses to Lo and HI.
Update both ISels to select them when they can.
Saves instructions here and there.

llvm-svn: 25001

Andrew Lenharth 20d0b81c04 FP select improvements (and likely breakage), oh and crazy people might want to *return* floating point values. Don't see why myself 
llvm-svn: 24658
 2005-12-11 03:54:31 +00:00
Andrew Lenharth 87bf2234b5 it helps if your conditionals are not reversed

Andrew Lenharth 873ed82a36 FPSelect and more custom lowering 
llvm-svn: 24535
 2005-11-30 16:10:29 +00:00
Andrew Lenharth 6db615df14 All sorts of stuff. 
Getting in on the custom lowering thing, yay
evilness with fp setcc, yuck
trivial int select, hmmm
in memory args for functions, yay
DIV and REM, always handy.  They should be custom lowered though.

Lots more stuff compiles now (go go single source!).  Of course, none of it
probably works, but that is what the nightly tester can find out :)

llvm-svn: 24533
 2005-11-30 07:19:56 +00:00
Andrew Lenharth 0294e33ea4 massive DAGISel patch. lots and lots more stuff compiles now

Chris Lattner fd07fcda67 Add some pattern fragments to simplify the repetitive parts of the patterns 
for some common ops and use them for a few examples.  Andrew, if you like
this, feel free to convert the rest over, if you hate it, feel free to
revert.

Andrew Lenharth 7b69867052 ret 0; works, not much else 
still lots of uglyness.
Maybe calls will come soon.
Fixing the return value of things will be necessary to make alpha work.

Andrew Lenharth 5e177826fd Implement count leading zeros (ctlz), count trailing zeros (cttz), and count 
population (ctpop).  Generic lowering is implemented, however only promotion
is implemented for SelectionDAG at the moment.

More coming soon.

Andrew Lenharth e0b789fdf5 so, if you beat on it, you too can talk emacs into having a sane indenting policy... Also, optimize many function calls with pc-relative calls (partial prologue skipping for that case coming soon), try to fix the random jumps to strange places problem by pesimizing div et. al. register usage and fixing up GP before using, some calling convention tweaks, and make frame pointer unallocatable (not strickly necessary, but let's go for correctness first)
