Nate Begeman 1b8121b227 Add bswap, rotl, and rotr nodes
Add dag combiner code to recognize rotl, rotr
Add ppc code to match rotl

Targets should add rotl/rotr patterns if they have them

Duraid Madina 014e8ee806 heh, 'sif it'd be a legalizer bug.

2006-01-10 05:26:01 +00:00
Duraid Madina e977a93bd5 support functions that return bool (this "should" work but doesn't,
*maybe* due to a legalizer bug.)

Duraid Madina 69ac08c683 nasty paste-o, calls passing more than 8 arguments along were having
args >8 put into the wrong place

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.

Duraid Madina 644e7db818 this is a hack, which may or may not hang around. In short:
whimper out of doing things the Right Way, and hack up a generic
'BRCALL' instruction, that gets generated when calls are lowered.
This gets selected by hand in the DAG isel, where it gets turned
into real (i.e. in tablegen) br.call instructions.

BUG: this dies on void calls, but seems to work otherwise?

2005-12-22 13:29:14 +00:00
Duraid Madina 3692fa14b8 we can't do this directly in lowering, so we need this case

Duraid Madina d0c146d59f this should take care of calls to varadic functions, but it doesn.,t
BUG: calling printf(string, float) will load the float into the wrong
register, completely forget about loading the string, etce

2005-12-22 06:39:57 +00:00
Duraid Madina a8de8a5db4 we need to emit the getf.d instruction in lowering, so add it
to IA64ISD

Duraid Madina 5ccf76fed3 I shoulda done this a *long* time ago (tm): implement calls properly,
i.e. r1/r12/rp are saved/restored regardless of scheduling/luck

TODO: calls to external symbols, indirect (function descriptor) calls,
      performance (we're being paranoid right now)

BUG: the code for handling calls to vararg functions breaks if FP
args are passed (this will make printf() go haywire so a bunch of
tests will fail)

BUG: this seems to trigger some legalize nastiness

Duraid Madina 8f6c86fe3b kill SelectCALL() in the DAG isel, we handle this in lowering now, like
SPARCv8. (we copy sparcv8's workaround for tablegen not being nice about
ISD::CALL/TAILCALL)

Chris Lattner c54cddd25b Add some explicit type casts so that tblgen knows the type of the shiftamount, which is not necessarily the same as the type being shifted.

Nate Begeman 6f8c1ace6e No longer track value types for asm printer operands, and remove them as
an argument to every operand printing function.  Requires some slight
tweaks to x86, the only user.

change.

Duraid Madina 4645db0948 ask for 16-byte aligned jmpbufs. This should unbreak C++ on IA64 (and
a bunch of other things) but is currently ignored by the code
generator.

Duraid Madina 31071b7471 oops, forgot to load GP for indirect calls, though the old code now commented
out failed (e.g. methcall) - now the code compiles, though it's not quite
right just yet (tm) ;)

would fix this but it's 3am! :O
