Chris Lattner fbc070bfdc Improve compatibility with VC++, patch contributed by Morten Ofstad! 
llvm-svn: 17126
 2004-10-18 15:54:17 +00:00
Chris Lattner 112fd88a05 Unify handling of constant pool indexes with the other code paths, allowing 
us to use index registers for CPI's

llvm-svn: 17082
 2004-10-17 07:49:45 +00:00
Chris Lattner 3b78938b9e Give the X86 JIT the ability to encode global+disp constants. Patch

Reid Spencer 7c16caa336 Changes For Bug 352 
Move include/Config and include/Support into include/llvm/Config,
include/llvm/ADT and include/llvm/Support. From here on out, all LLVM
public header files must be under include/llvm/.

Chris Lattner 4dfadc05e6 Remove dead method 
llvm-svn: 15647
 2004-08-11 02:26:39 +00:00
Chris Lattner c856e90d1d Make sure to emit the immediate byte for instructions like: 
shrd [mem], reg, imm

This fixes the jit-ls failure on 186.crafty.

llvm-svn: 14914
 2004-07-17 20:26:14 +00:00
Chris Lattner 82baa9c394 Convert to the new TargetMachine interface. 
llvm-svn: 13952
 2004-06-02 05:55:25 +00:00
Brian Gaeke de5ccc18e3 Don't keep track of references to LLVM BasicBlocks while emitting; use 
MachineBasicBlocks instead.

llvm-svn: 13568
 2004-05-14 06:54:58 +00:00
Brian Gaeke 6e102a7edd Use emitWordAt() to emit forward-branch fixups. 
llvm-svn: 13120
 2004-04-23 17:11:16 +00:00
Chris Lattner eaa28a29ae Add support for new instruction type 
llvm-svn: 12894
 2004-04-13 17:18:51 +00:00
Alkis Evlogimenos 508b459d12 Add emitInstruction() API so that we can get the bytes of a simple instruction 
llvm-svn: 12252
 2004-03-09 03:34:53 +00:00
Alkis Evlogimenos a7c2da3af5 Constify things a bit 
llvm-svn: 12251
 2004-03-09 03:30:12 +00:00
Alkis Evlogimenos 194939086d Each instruction now has both an ImmType and a MemType. This describes 
the size of the immediate and the memory operand on instructions that
use them. This resolves problems with instructions that take both a
memory and an immediate operand but their sizes differ (i.e. ADDmi32b).

llvm-svn: 11967
 2004-02-28 22:02:05 +00:00
Alkis Evlogimenos 58270fcf1f Rename MRMS[0-7]{r,m} to MRM[0-7]{r,m}. 
llvm-svn: 11921
 2004-02-27 18:55:12 +00:00
Chris Lattner 30e73e3442 Add support for GlobalAddress's for alkis 
llvm-svn: 11560
 2004-02-17 18:23:55 +00:00
Chris Lattner c07eeaef6b Expand the repertoire of the forms we can print and encode. 
llvm-svn: 11537
 2004-02-17 07:40:44 +00:00
Alkis Evlogimenos bbf53937a4 Make dense maps keyed on physical registers smallerusing 
MRegisterInfo::getNumRegs() instead of
MRegisterInfo::FirstVirtualRegister.

Also use MRegisterInfo::is{Physical,Virtual}Register where
appropriate.

llvm-svn: 11477
 2004-02-15 21:37:17 +00:00
Alkis Evlogimenos 6a35516dcc Add back machine code deleter pass until we get a MachineCode pass 
that will be responsible for the creation of MachineFunctions and will
be required by all MachineFunctionPass passes.

llvm-svn: 11453
 2004-02-15 00:03:15 +00:00
Chris Lattner 8dc99feeaf Add support for the rep movs[bwd] instructions, and emit them when code 
generating the llvm.memcpy intrinsic.

llvm-svn: 11351
 2004-02-12 17:53:22 +00:00
Alkis Evlogimenos 80da865f77 Change MachineBasicBlock's vector of MachineInstr pointers into an 
ilist of MachineInstr objects. This allows constant time removal and
insertion of MachineInstr instances from anywhere in each
MachineBasicBlock. It also allows for constant time splicing of
MachineInstrs into or out of MachineBasicBlocks.

llvm-svn: 11340
 2004-02-12 02:27:10 +00:00
Alkis Evlogimenos 327426411e Modify the two address instruction pass to remove the duplicate 
operand of the instruction and thus simplify the register allocation.

llvm-svn: 11124
 2004-02-04 22:17:40 +00:00
Alkis Evlogimenos 68cff6bf4d Remove floating point killer pass. This is now implemented in the 
instruction selector by adding a new pseudo-instruction
FP_REG_KILL. This instruction implicitly defines all x86 fp registers
and is a terminator so that passes which add machine code at the end
of basic blocks (like phi elimination) do not add instructions between
it and the branch or return instruction.

llvm-svn: 10562
 2003-12-20 16:22:59 +00:00
Chris Lattner 452597611f Finally, _actually delete the machine code_ for a function, after it has 
been emitted.  Also, since the FPK pass is causing memory access violations,
disable it.

llvm-svn: 10542
 2003-12-20 01:22:19 +00:00
John Criswell c6efb11f02 Modified cast so that it converts the int to a long before casting to 
a pointer.  This evades a warning emitted by GCC when we cast from
unsigned int (32 bit) to void * (64 bit) on SparcV9.

llvm-svn: 10435
 2003-12-12 19:57:48 +00:00

namespacification.

llvm-svn: 9903
 2003-11-11 22:41:34 +00:00
John Criswell 482202a601 Added LLVM project notice to the top of every C++ source file. 
Header files will be on the way.

llvm-svn: 9298
 2003-10-20 19:43:21 +00:00
Chris Lattner 97e1b55723 * Rename X86::IMULr16 -> X86::IMULrr16 
* Implement R1 = R2 * C where R1 and R2 are 32 or 16 bits. This avoids an
  extra copy into a register, reducing register pressure.

llvm-svn: 9278

Brian Gaeke 845b5af4d4 addPassesToJITCompile and addPassesToEmitMachineCode now take a 
FunctionPassManager, to support function-at-a-time compilation and
 emission of code.

llvm-svn: 7821
 2003-08-13 18:17:27 +00:00
Chris Lattner 7c257321c7 This is the real fix for the previous register allocator problem. 
Physical registers should not float around.

John Criswell 3ef61afb76 Merged in autoconf branch. This provides configuration via the autoconf 
system.

llvm-svn: 7014
 2003-06-30 21:59:07 +00:00
Brian Gaeke 7a719ed20c Isolate machine-dependent use of <alloca.h> in "Support/Alloca.h", 
so that we can easily change its use to be conditional on the result of
an autoconf test later.

Chris Lattner d964c3b9fd IMPLICIT_DEF was not the beautiful elegant solution I thought it was going 
to be.  In fact, it made stuff worse.  :(
