Chris Lattner 1e1abdd6ed Do not function resolve intrinsics. This prevents warnings and possible bad 
things from happening due to

declare bool %llvm.isunordered(double, double)
declare bool %llvm.isunordered(float, float)

Brian Gaeke 21305c6f0c Support alloca instructions. 
Support copying floating-point constants to registers.
Add assertion to visitCallInst to abort if we hit a NULL calledFunction, for now.

Chris Lattner aa27623b99 Codegen sub C, X a little bit better for register pressure. Instead of 
mov REG, C
sub REG, X

generate:

neg X
add X, C

which uses one less reg

Chris Lattner b30d12292a Fold setcc instructions into select and branches that are not in the same BB as 
the setcc.

Brian Gaeke c37af629b4 Make storeRegToStackSlot slightly shorter. 
Make copyRegToReg return 1 instead of -1.
Edit a comment in emitPrologue().

Brian Gaeke eca9546dc3 Set the isBranch and isTerminator flags on branch instructions correctly. 
Add a FIXME about the (currently unused) JMPL instructions.

llvm-svn: 14210
 2004-06-17 22:34:29 +00:00
Brian Gaeke 63c1d6eda8 Emit stores correctly; don't fail an assertion. 
llvm-svn: 14209
 2004-06-17 22:34:19 +00:00
Brian Gaeke c4ee938f55 Support generating machine instructions for Phi nodes (based on x86, but with 
modifications for 1 LLVM BB --> many MBBs).
Fix store operand order: make it always be Base, Offset, SrcReg (think
"[ Base + Offset ] = SrcReg").
Rewrite visitBranchInst() to be even dumber (but working) -- give up on
the branch fallthrough trick, for the time being.
Make visitSetCondInst() work.

Brian Gaeke 27b13253d9 I love the smell of a freshly broken PowerPC build in the morning. 
llvm-svn: 14206
 2004-06-17 22:27:04 +00:00
Brian Gaeke 4300ca9d32 Make debugging dumps w/ multiple MachineBBs for a given LLVM BB readable.

 2004-06-17 22:26:53 +00:00
Chris Lattner 7887da36de Do not fold loads into instructions if it is used more than once. In particular 
we do not want to fold the load in cases like this:

  X = load
    = add A, X
    = add B, X

Chris Lattner f03f320b79 Fix compilation problem on freebsd. Problem noted by Vladimir Merzliakov in 
PR371

 2004-06-17 21:20:52 +00:00
Brian Gaeke 2f2b5f5b93 Use addGlobalAddress and addMBB for call & branch targets instead of addPCDisp. 
Abort if we see a PCRelativeDisp MachineOperand, to be safe. This matches
the X86 backend.

Chris Lattner 6b7275996c Rename Type::PrimitiveID to TypeId and ::getPrimitiveID() to ::getTypeID() 
llvm-svn: 14201
 2004-06-17 18:19:28 +00:00

Misha Brukman a1237d00d6 Since the Great LLVM Tool Renaming(tm), we no longer have collisions between our 
assembler/linker and the system equivalents.

Brian Gaeke 661963c63f Fix typo in DEBUG printout. 
llvm-svn: 14196
 2004-06-17 07:26:52 +00:00
Chris Lattner 6f4a596234 Fix a recent regression in Applications/sgefa that Alkis pointed out to me. 
The vector may actually be empty if the register that we are marking as
recently used is not actually allocatable.  This happens for physical registers
that are not allocatable, like the ST(x) registers on X86.

Brian Gaeke 20e09e5c7b Um, did someone make a typo or something?

Chris Lattner f64f794cad llvm.isnan is dead, long live llvm.isunordered! 
llvm-svn: 14190
 2004-06-15 21:50:46 +00:00
Chris Lattner 7011d35594 Remove support for llvm.isnan. Alkis wins :) 
llvm-svn: 14189
 2004-06-15 21:48:07 +00:00
Chris Lattner ee92bfca97 This testcase is a bit silly now, but oh well :)

 2004-06-15 21:37:54 +00:00
Chris Lattner 70dfc06e02 Add basic support for the isunordered intrinsic. The isnan stuff still needs to go 
llvm-svn: 14185
 2004-06-15 21:36:44 +00:00
Chris Lattner 75bcc59f1c Right, stop being silly 
llvm-svn: 14184
 2004-06-15 21:29:40 +00:00
Chris Lattner ce4ac095f0 Add a nan, stop testing isnan 
llvm-svn: 14183

Brian Gaeke 476c73b241 Fix thinko in visitor... ShiftInsts should currently be delegated 
to visitBinaryOperator.

llvm-svn: 14182
 2004-06-15 21:09:46 +00:00
Chris Lattner b1f0478f1d Do not dereference end iterators. It's really bad for the asmwriter's health. 
This possibly fixes PR370

llvm-svn: 14181
 2004-06-15 21:07:32 +00:00
Brian Gaeke 675c0e9701 I think we'll use the standard lowering passes for now. 
llvm-svn: 14179
 2004-06-15 20:37:12 +00:00
Brian Gaeke 0c8ee30d53 Fix bug generating code for void call instructions: don't call 
getReg() on void value.

llvm-svn: 14178
 2004-06-15 20:06:32 +00:00
Brian Gaeke 065a6cb93a Squash a warning from the Solaris assembler by aligning the stack 
on a double-word boundary instead of a single-word boundary.

llvm-svn: 14177
 2004-06-15 19:53:10 +00:00
Brian Gaeke ad98a9b526 Allow special-casing of operand printing based on opcode. Print 
non-register, non-immed. arguments to SETHI and OR using %hi() and
%lo() respectively.

llvm-svn: 14176
 2004-06-15 19:52:59 +00:00
Brian Gaeke 19fbd28a06 Support constant GEP expressions. 
Support copying long constants to register pairs.
Support copying ConstantPointerNulls and ConstantPointerRefs to registers.

Misha Brukman 342693e35b The correct prototype is `int atoi(CONST char*)'. Unbroke AIX build.

Misha Brukman bba0f0e492 Add file comment.

 2004-06-14 15:13:59 +00:00
Brian Gaeke 21370771ba Quick hack to get this file compiling again on Mac OS X. The right thing to do 
is write an autoconf macro that checks whether __isnan or isnan actually works
**using the C++ compiler after #include <cmath>**, instead of doing it the easy
way with AC_CHECK_FUNCS().

llvm-svn: 14171
 2004-06-14 06:33:19 +00:00
Brian Gaeke 99c6539bce Make -print-machineinstrs even stronger. You get to see the final code after 
peepholing, and make it work the same way in the JIT as in LLC.
