Misha Brukman 2a0baf1a2b This way it's easier to test: if the call to external exit(0) succeeded, 
program exits with code 0, no error. If the call does not work/succeed, main
returns 1, so we notice it. The other way around doesn't work. :)

Also make all loads & stores 4-byte aligned for performance. ;)

Misha Brukman 2ef75daf78 This is supposed to provide correct size for datatypes. Supposedly.

Misha Brukman 260dbc79fc Take advantage of our knowledge of 2-address X86 instructions and 
register-allocated them appropriately.

llvm-svn: 4976
 2002-12-12 23:20:31 +00:00
Misha Brukman eedcef4f92 Define the 2-address flag used by X86 instructions (add,sub,and,or,xor) that 
need to be declared as such.

 2002-12-12 23:19:51 +00:00
Misha Brukman 7b21678aed Added the flag to mark instructions which are really 2-address instructions in 
X86, but would be 3-address in any normail architecture.

Brian Gaeke 5e91d38ecb This checkin is brought to you by the brian gaeke allnighter fund. 
(lib/Target/X86) InstSelectSimple.cpp:
 Include llvm/DerivedTypes.h and iostream.
 Refactor visitMul out into a wrapper around doMultiply(), so that we
  can do multiplications on temporary values when we are doing
  getelementptrs.
 Refactor part of getReg out into makeAnotherReg, so that we can create
  registers willy-nilly to hold temporary values, when we are doing
  getelementptrs.
 Add stub implementations of visitMallocInst and visitAllocaInst.
 Add initial implementation of visitGetElementPtrInst.
 In copyConstantToRegister:
  We throw a *lot* of our asserts here. So, when we want to throw an
   assert, print out to stderr whatever expr or whatever constant made
   us barf.
  Support copying ConstantPointerNull to register, using a move immediate
   of zero.
 Rename FLDr4 and FLDr8 to FLDr32 and FLDr64, so that they match the meanings
  of the numbers in the other instruction names. All uses modified.
 Teach visitCallInst to extract byte- and short-class return values
  from subregs of EAX.  Add a FIXME note about how we would do it for
  float-class return values.
 Add a FIXME note about how we would cast float to int and back.

X86InstrInfo.def:
 Rename FLDr4 and FLDr8 to FLDr32 and FLDr64, so that they match the meanings
  of the numbers in the other instruction names. All uses modified.

(tools/jello) GlobalVars.cpp:
 Include iostream.
 If we have to emit a floating-point constant to memory, gamble and use
  the same method as for ints.
 If we have to emit a ConstantPointerNull to memory, try using a "void *"
  and "NULL".
 Otherwise, if we are going to throw an assert, print out whatever constant
  made us barf, first.

Misha Brukman 1028ac46d6 'graph' is spelled without a 'c'. 
Also added Statistic counters for NoAlias and MayAlias.

Misha Brukman 356163f48a ipa.a only needs to be mentioned once, and spaces should be used instead of 
tabs for readability.

llvm-svn: 4970
 2002-12-12 05:29:32 +00:00
Misha Brukman 0d19db3c34 No need to specify the class if the method is within the class declaration.

parallelization pass.

Vikram S. Adve c864ab1e33 This file implements the function DemoteRegToStack(), which takes a 
virtual register computed by an Instruction& X and replaces it with
a slot in the stack frame, allocated via alloca.

Vikram S. Adve 5fb974b74a This file provides the function DemoteRegToStack(), which takes a

Vikram S. Adve 9a672d17ae This file implements a pass that automatically parallelizes a program, 
using the Cilk multi-threaded runtime system to execute parallel code.
The current version inserts too many sync() operations in the program
because it does not attempt to optimize their placement.

Vikram S. Adve 41aab86c40 The pass Parallelize automatically parallelizes a program using the 
Cilk multi-threaded runtime system to execute parallel code.  This file
exposes some routines needed for code generation for that pass.

 2002-12-09 05:53:11 +00:00
Vikram S. Adve 42b7335d7c Repeat ipa.a. Since IPModRef is currently only used in analysis.o, 
it was causing linking errors.

Vikram S. Adve 775e51d87a Iterator that enumerates the ProgramDependenceGraph (PDG) for a function, 
i.e., enumerates all data and control dependences for the function.

 2002-12-08 14:13:19 +00:00
Vikram S. Adve 8975afdfc4 An explicit representation of dependence graphs, and a pass that

using interprocedural Mod/Ref information.

 2002-12-06 21:19:07 +00:00
Vikram S. Adve 04aee9478c Two bug fixes: 
(1) Make entries for Constant values in the ScalarMap.
(2) Set MOD bit for the node pointed to by the
    argument of a free instruction.

 2002-12-06 21:17:10 +00:00
Vikram S. Adve 0d5559fdfb Fix several related bugs in DSNode::mergeWith() caused by the 
fact that the incoming nodes may be merged away at intermediate
steps.  Use an extra level of indirection via DSNodeHandles
to track the nodes being merged.  All this now happens in a
static helper function MergeNodes().

llvm-svn: 4947
 2002-12-06 21:15:21 +00:00
Vikram S. Adve 00ca82dbd2 Added static helper method MergeNodes(). See DataStructure.cpp for more.
