Victor Hernandez 8acf2956b8 Remove AllocationInst. Since MallocInst went away, AllocaInst is the only subclass of AllocationInst, so it no longer is necessary. 
llvm-svn: 84969

Chris Lattner fdd8790718 strength reduce a ton of type equality tests to check the typeid (Through 
the new predicates I added) instead of going through a context and doing a
pointer comparison.  Besides being cheaper, this allows a smart compiler
to turn the if sequence into a switch.

Nick Lewycky 7465cd769c Add more newlines to make up for the ones removed from the end of instructions.

Chris Lattner b25de3ff60 eliminate the "Value" printing methods that print to a std::ostream. 
This required converting a bunch of stuff off DOUT and other cleanups.

Dan Gohman 915302c605 Make SROA and PredicateSimplifier cope if TargetData is not 
available. This is very conservative for now.

Owen Anderson 55f1c09e31 Push LLVMContexts through the IntegerType APIs. 
llvm-svn: 78948
 2009-08-13 21:58:54 +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
Owen Anderson b292b8ce70 Move more code back to 2.5 APIs.

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.

llvm-svn: 77579
 2009-07-30 04:20:37 +00:00
Owen Anderson 4056ca9568 Move types back to the 2.5 API. 
llvm-svn: 77516
 2009-07-29 22:17:13 +00:00
Owen Anderson 487375e9a2 Move ConstantExpr to 2.5 API.

Owen Anderson 4aa3295a65 Return ConstantVector to 2.5 API. 
llvm-svn: 77366
 2009-07-28 21:19:26 +00:00
Daniel Dunbar 4975db6276 Initial update to VMCore to use Twines for string arguments. 
- The only meat here is in Value.{h,cpp} the rest is essential 'const
   std::string &' -> 'const Twine &'.

Owen Anderson edb4a70325 Revert the ConstantInt constructors back to their 2.5 forms where possible, thanks to contexts-on-types. More to come.

Owen Anderson b6b2530000 Move EVER MORE stuff over to LLVMContext.

Torok Edwin fbcc663cbf llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable. 
This adds location info for all llvm_unreachable calls (which is a macro now) in
!NDEBUG builds.
In NDEBUG builds location info and the message is off (it only prints
"UREACHABLE executed").

llvm-svn: 75640
 2009-07-14 16:55:14 +00:00
Torok Edwin 56d0659726 assert(0) -> LLVM_UNREACHABLE. 
Make llvm_unreachable take an optional string, thus moving the cerr<< out of
line.
LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for
NDEBUG builds.

llvm-svn: 75379
 2009-07-11 20:10:48 +00:00
Torok Edwin ccb29cd290 Convert more assert(0)+abort() -> LLVM_UNREACHABLE, 
and abort()/exit() -> llvm_report_error().

llvm-svn: 75363
 2009-07-11 13:10:19 +00:00
Owen Anderson 1e5f00e7a7 This started as a small change, I swear. Unfortunately, lots of things call the [I|F]CmpInst constructors. Who knew!?

Owen Anderson 38264b1554 "LLVMContext* " --> "LLVMContext *"

Owen Anderson e70b637033 More LLVMContext-ification. 
llvm-svn: 74807

Instructions.

Eli Friedman ee94e3cc9e PR4286: Make RewriteLoadUserOfWholeAlloca and 
RewriteStoreUserOfWholeAlloca deal with tail padding because 
isSafeUseOfBitCastedAllocation expects them to.  Otherwise, we crash 
trying to erase the bitcast.

llvm-svn: 72688
 2009-06-01 09:14:32 +00:00
Duncan Sands af9eaa830a Rename PaddedSize to AllocSize, in the hope that this 
will make it more obvious what it represents, and stop
it being confused with the StoreSize.

llvm-svn: 71349
 2009-05-09 07:06:46 +00:00
Chris Lattner c48091f141 fix RewriteStoreUserOfWholeAlloca to use the correct type size 
method, fixing a crash on PR4146.  While the store will 
ultimately overwrite the "padded size" number of bits in memory,
the stored value may be a subset of this size.  This function
only wants to handle the case where all bits are stored.

llvm-svn: 71224
 2009-05-08 15:54:41 +00:00
Chris Lattner 69223bb7f5 fix a crash on a pointless but valid zero-length memset, rdar://6808691

Zhou Sheng 4e2af3cb55 Explicitly check for StoreInst, do not lose the chance to delete 
unused loads or bitcasts.

 2009-03-18 12:48:48 +00:00
Zhou Sheng 05bea906c1 Revert my previous change on Local.cpp, instead, fix the bug on scalarrepl. 
If the instruction has no users, it is also not only used by debug info 
and should not be deleted.

Chris Lattner 21a84f3054 teach SROA to handle promoting vector allocas with a memset into them into 
a vector type instead of into an integer type.

llvm-svn: 66368
 2009-03-08 04:17:04 +00:00
Chris Lattner c009757761 Enhance SROA to "promote to scalar" allocas which are 
memcpy/memmove'd into or out of.  This fixes a serious
perf issue that Nate ran into.

llvm-svn: 66366
 2009-03-08 04:04:21 +00:00
Chris Lattner dc35e5b43a change the MemIntrinsic get/setAlignment method to take an unsigned 
instead of a Constant*, which is what the clients of it really want.

llvm-svn: 66364
 2009-03-08 03:59:00 +00:00
Chris Lattner 334268a211 Introduce a new MemTransferInst pseudo class, which is a common 
parent between MemCpyInst and MemMoveInst, simplify some code to
use it.
