Mon P Wang a95379d165 When InstCombine simplifies a load -> extract element to gep -> load, place 
the new load by the old load instead of by the extract element because
a store could have occurred between the load and extract element.

 2009-08-12 16:04:34 +00:00
Owen Anderson 117c9e8497 Add contexts to some of the MVT APIs. No functionality change yet, just the infrastructure work needed to get the contexts to where they need to be first.

Daniel Dunbar 3b5008e23a More ProfileInfo improvements. 
- Part of optimal static profiling patch sequence by Andreas Neustifter.

 - Store edge, block, and function information separately for each functions
   (instead of in one giant map).

 - Return frequencies as double instead of int, and use a sentinel value for
   missing information.

Devang Patel b1106fbdbc Fix dom frontier update. This fixes PR4667.

llvm-svn: 78333
 2009-08-06 20:53:06 +00:00
Owen Anderson 03cb69fbd1 Privatize the StructType table, which unfortunately involves routing contexts through a number of APIs. 
llvm-svn: 78258
 2009-08-05 23:16:16 +00:00
Dan Gohman 298bce2aa9 Check for !isa<Constant> instead of isa<Instruction>. This 
matches what the comment says, and it avoids spurious BitCast
instructions for Argument values.

llvm-svn: 78121
 2009-08-04 23:23:56 +00:00
Dan Gohman f011f5a8a2 Add a new Constant::getIntegerValue helper function, and convert a 
few places in InstCombine to use it, to fix problems handling pointer
types. This fixes the recent llvm-gcc bootstrap error.

llvm-svn: 78005
 2009-08-03 22:07:33 +00:00
Eli Friedman cfd3bbe643 Make SimplifyDemandedUseBits generate vector constants where 
appropriate.  Patch per report on llvmdev.  No testcase because the 
original report didn't come with a testcase, and I can't come up with a case
that actually fails.

llvm-svn: 77986
 2009-08-03 19:15:42 +00:00
Owen Anderson 5a1acd9912 Move a few more APIs back to 2.5 forms. The only remaining ones left to change back are 
metadata related, which I'm waiting on to avoid conflicting with Devang.

llvm-svn: 77721
 2009-07-31 20:28:14 +00:00
Dan Gohman ef3ef7f645 Fix GVN's debug output, now that operator<< on Value* doesn't print 
a trailing newline.

llvm-svn: 77719
 2009-07-31 20:24:18 +00:00
Bill Wendling 2602bb4cdc - Convert the rest of the DOUTs to DEBUG+errs(). 
- One formatting change.

No intended functionality change.

Daniel Dunbar 132f78395a Twines: Don't allow implicit conversion from integers, this is too tricky. 
llvm-svn: 77605
 2009-07-30 17:37:43 +00:00
Daniel Dunbar 6afdc5e694 Switch obvious clients to Twine instead of utostr (when they were already using 
a Twine, e.g., for names).
 - I am a little ambivalent about this; we don't want the string conversion of
   utostr, but using overload '+' mixed with string and integer arguments is
   sketchy. On the other hand, this particular usage is something of an idiom.

Daniel Dunbar 98ddd164d8 Fix PR4645 which was fallout from the fix for PR4641. 
- Call RAUW to delete all instructions (this is a patch from Nick Lewycky).

llvm-svn: 77494
 2009-07-29 18:55:55 +00:00
Nick Lewycky f82326b984 Bulk erasing instructions without RAUWing them is unsafe. Instead, break them 
into a new BB that has no predecessors.

Devang Patel a4f43fb5dd Rename MDNode.h header. It defines MDnode and other metadata classes. 
New name is Metadata.h.

to a few tests where it is required for the expected transformation.

Dan Gohman a3dcff5900 Grab the LLVMContext and parent Module of SI ahead of the 
point where SI can get deleted. This fixes a use of free'd memory.
This fixes Externals/Povray.

llvm-svn: 77285
 2009-07-28 00:37:06 +00:00
Mike Stump 4798763e14 Fix a release-asserts warning. Debug functions should be marked used, 
if there are no other uses.  If people don't need this routine
anymore, if should be deleted.

llvm-svn: 77274
