Chris Lattner e94db67c4f Move addPassesToEmitAssembly from TargetMachine to UltraSparc because it

Chris Lattner 42c66c4887 Minor cleanups 
Make sure to have a pass name

llvm-svn: 4268
 2002-10-23 01:12:01 +00:00
Chris Lattner 49f4242d2b - Fix a really nasty bug in the bytecode reader that caused it to fail 
reading bytecode files with > 255 types in them, but only when optimization
    is enabled.  This was caused by GCC shrinking an enum to a single byte
    instead of a whole word.

llvm-svn: 4266
 2002-10-23 00:51:54 +00:00
Chris Lattner 95fcefcb7e Wow, for some reason, when reading bytecode from stdin, we were only reading 
4 bytes at a time.  Change this to read blocks of 4k

llvm-svn: 4265

Chris Lattner 5ae3bd630d Ensure definate initialization 
llvm-svn: 4263
 2002-10-22 23:34:11 +00:00
Chris Lattner ce64eddb71 - Two minor improvements to the MachineInstr class to reduce footprint and 
overhead: Merge 3 parallel vectors into 1, change regsUsed hash_set to be a
    bitvector.  Sped up LLC a little less than 10% in a debug build!

llvm-svn: 4261
 2002-10-22 23:16:21 +00:00
Chris Lattner 51a2c3cc2d - Make sure to only keep track of mappings that the TD pass may need in the 
future.  This prevents having spurious map entries to nodes that we really
    don't care about.  This allows us to reenable the DeadNodeElim, which was
    disabled.

llvm-svn: 4260
 2002-10-22 16:01:03 +00:00
Chris Lattner d90e74ae13 The callee is not correct, and confuses the TD pass. Null it out. 
llvm-svn: 4259
 2002-10-22 15:58:46 +00:00
Chris Lattner 820d971233 - Rename AnalysisUsage::preservesAll to getPreservesAll & preservesCFG to 
setPreservesCFG to be less confusing.

llvm-svn: 4253
 2002-10-21 19:50:29 +00:00
Chris Lattner f76087336f - Add "ResolvingCaller" to the CallSite record. This keeps track of which 
function was finally able to resolve the function call.  Adding this allows
    the TD pass to actually work right!
  - Temporarily disable dead node pruning.  This will be reenabled soon.

llvm-svn: 4252
 2002-10-21 19:47:18 +00:00
Chris Lattner c6191df9af Add another copy ctor form 
llvm-svn: 4251
 2002-10-21 15:32:34 +00:00
Chris Lattner 78c1e7d83c As it turns out, we don't need a fully generic mapping copy ctor, we just need 
something that maps through a std::map.  Since this simplified the client and
implementation code, do so now.

llvm-svn: 4250
 2002-10-21 15:04:18 +00:00
Chris Lattner 32438d8c84 Don't create a new node for every reference to a global. This caused a huge 
node explosion that doesn't help anything at all.  In previous versions of
the representation this DID help, but not anymore.

llvm-svn: 4249
 2002-10-21 13:51:30 +00:00
Chris Lattner 800b7e33df Fix a confusing bug that caused return value and callee pointers to not 
be printed!

llvm-svn: 4242
 2002-10-21 02:18:55 +00:00
Chris Lattner 5c3ce31e1f - Make DSCallSite not inherit from std::vector. Renamed methods slightly. 
Make copy ctor have two versions to avoid dealing with conditional template
    argument.  DSCallSite ctor now takes all arguments instead of taking one
    and being populated later.

 2002-10-20 20:29:10 +00:00
Vikram S. Adve dc9e142686 Added a first-class representation for each call site that can be 
used in the DS graphs.  Essentially, what was vector<DSNodeHandle>
before is now a DSCallSite with the same vector, plus pointers to the
CallInst and the caller Function.  The special-purpose class
BUDataStructure::CallSite is no longer needed.

Chris Lattner f10327ebce * First try at implementing TD pass this does not merge global nodes yet, 
among other things.
  * Significant rewrite of TD pass to avoid potentially N^2 algorithms if
    possible.  It is still not complete, but at least it's checked in now.

llvm-svn: 4169
 2002-10-14 16:32:24 +00:00
Vikram S. Adve f5492b0c5b Significant improvement: GEP used by a load or store no longer generates 
a separate ADD; instead just use the indexed load/store instruction!
Also, a bug fix: folding a GEP with a leading non-zero index with
its predecessor was incorrect: now it only happens if the predecessor
is pointing to an indexable type (aka SequentialType).

llvm-svn: 4168
 2002-10-14 16:30:55 +00:00
Chris Lattner 74cb2d2503 Allow emission of names that start with an underscore. This is needed to 
interface with code that uses symbols in the ansi-c protected namespace.  In
most cases this comes from system header files, such as stdio.h.  In particular,
without this change, a reference to the __iob symbol is mangled into ll_iob,
which is not resolved by libc.

llvm-svn: 4165

 2002-10-14 03:34:17 +00:00
Chris Lattner 2862d2ec71 There is no way to guarantee that constants are not forward referenced. 
Handle forward referenced constants in a general way.  This fixes bug:
Assembler/2002-10-13-ConstantEncodingProblem.llx and allows the SPEC
197.parser benchmark to be built

llvm-svn: 4161
 2002-10-14 03:33:02 +00:00
Chris Lattner 163b890dfb - Dramatically simplify the Constant::mutateReferences implementation,

 2002-10-14 00:48:57 +00:00
Vikram S. Adve a202c0dbfa Don't try to compute the size of an "array" element if the index is 0: 
the size may be unknown, and is not needed.

llvm-svn: 4153
 2002-10-13 21:47:44 +00:00
Chris Lattner 149376dee5 - Change Function's so that their argument list is populated when they are

    now a Function ALWAYS has a populated argument list.

llvm-svn: 4149
 2002-10-13 20:57:00 +00:00
Chris Lattner 69ce8674b5 - Rename Instruction::First*Op to *OpsBegin, and Num*Ops to *OpsEnd to

Vikram S. Adve 9e5eb46362 Use vectors instead of hash_maps for issueGaps and conflictLists. 
These hash lookups were a major sink of time because they happen so often!
Also, add option to disable scheduling.

llvm-svn: 4135
 2002-10-13 00:34:10 +00:00
Vikram S. Adve 10d8164013 Several major fixes, particularly in emitting constant aggregates: 
(1) Padding bytes between structure fields (for alignment) were never
    being emitted into the constant pool so the layout did not match!
(2) In printing constants, structures containing structures or arrays
    were never handled.
(3) Support new model for external/uninitialized/initialized globals.
    Uninitialized globals are no longer emitted since they are external.
    Initialized globals may go either in .bss or in .data.

llvm-svn: 4134
 2002-10-13 00:32:18 +00:00
Vikram S. Adve 78044fbc8e Don't use %l0 for large operands to a SAVE since it is needed *before* SAVE! 
We now use %g1 instead since that is shared and volatile.

Vikram S. Adve d2dc60e5d9 (1) Try to evaluate constant when multiplying 2 constants. 
(2) Use intelligent multiply selection code for array allocas.
(3) Don't use cache padding for alloca'd stack slots!
(4) Bug fix in handling call arguments: was not copying sixth FP arg
    to int reg. when calling a function with no prototype.
