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.

Owen Anderson 23a204d91b Move getTrue() and getFalse() to 2.5-like APIs.

Daniel Dunbar 9813b0b025 Eliminate some uses of DOUT, cerr, and getNameStart().

Daniel Dunbar 0dd5e1ed39 More migration to raw_ostream, the water has dried up around the iostream hole. 
- Some clients which used DOUT have moved to DEBUG. We are deprecating the
   "magic" DOUT behavior which avoided calling printing functions when the
   statement was disabled. In addition to being unnecessary magic, it had the
   downside of leaving code in -Asserts builds, and of hiding potentially
   unnecessary computations.

Owen Anderson 47db941fd3 Get rid of the Pass+Context magic. 
llvm-svn: 76702
 2009-07-22 00:24:57 +00:00
Owen Anderson c37bc69e91 Rename getConstantInt{True|False} to get{True|False} at Chris' behest. 
llvm-svn: 76598
 2009-07-21 18:03:38 +00:00
Owen Anderson 20b34ac794 Move the ConstantInt uniquing table into LLVMContextImpl. This exposed a number of issues in 
our current context-passing stuff, which is also fixed here

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
Owen Anderson 542619e6d5 Move more functionality over to LLVMContext. 
llvm-svn: 75497
 2009-07-13 20:58:05 +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().

Owen Anderson f1f1743b2e Finish LLVMContext-ing lib/Analysis. This required pushing LLVMContext's through the ValueTracking API. 
llvm-svn: 74873

Owen Anderson 39f00cc1d4 Thread LLVMContext through the constant folding APIs, which touches a lot of files.

Nick Lewycky 7ea68536b5 Don't crash on multiple return value with no obvious inserted value. 
Fixes PR4314.

Nick Lewycky 206876e2da Use Operands.data() instead of &Operands[0] where Operands is a potentially 
empty SmallVector.

Duncan Sands 1f15ca7c7a Factorize out a concept - no functionality change. 
llvm-svn: 67454
 2009-03-21 21:27:31 +00:00
Duncan Sands a09e0afe74 Don't load values out of global constants with weak 
linkage: the value may be replaced with something
different at link time.  (Frontends that want to
allow values to be loaded out of weak constants can
give their constants weak_odr linkage).

llvm-svn: 67407

Rafael Espindola 6de96a1b5d Add the private linkage.

 2008-08-14 21:31:10 +00:00
Dan Gohman 8ded5d5884 Fix SCCP's handling of struct value loads and stores. SCCP doesn't 
track individual leaf values in such cases, so it needs to treat
struct values as normal values in this case.

llvm-svn: 54760
 2008-08-13 21:22:48 +00:00
Dan Gohman fa1211f69b Enable first-class aggregates support. 
Remove the GetResultInst instruction. It is still accepted in LLVM assembly
and bitcode, where it is now auto-upgraded to ExtractValueInst. Also, remove
support for return instructions with multiple values. These are auto-upgraded
to use InsertValueInst instructions.

The IRBuilder still accepts multiple-value returns, and auto-upgrades them
to InsertValueInst instructions.

 2008-07-23 00:34:11 +00:00
Dan Gohman a5dd67f002 Tidy up some commments and use the getAggregateOperand and 
getInsertedValueOperand accessors. Thanks Matthijs!

llvm-svn: 52543
 2008-06-20 16:41:17 +00:00
Dan Gohman b5210efb31 Fix the conditions under which SCCP should examine insertvalue 
instructions. Thanks to Matthijs Kooijman for pointing this out!

llvm-svn: 52542
 2008-06-20 16:39:44 +00:00
Dan Gohman 041f9d03ff Teach SCCP about insertvalue and extractvalue, and about 
propagating constants across aggregate return values when
insertvalue and extractvalue are used.

Chris Lattner 5c207c83c6 Fix PR2358 by resolving calls with undef arguments to overdefined.

Dale Johannesen fecb88249f Allow for switch with no cases. Was causing fault 
in gcc.dg/pr27531-1.c.

llvm-svn: 51464
 2008-05-23 01:01:31 +00:00
Dan Gohman d78c400b5b Clean up the use of static and anonymous namespaces. This turned up 
several things that were neither in an anonymous namespace nor static
but not intended to be global.

llvm-svn: 51017
 2008-05-13 00:00:25 +00:00
Chris Lattner 47fed61526 Fix various DOUTs to not call the extremely expensive Value::getName() 
method.  DOUT statements are disabled when assertions are off, but the
side effects of getName() are still evaluated.  Just call getNameSTart,
which is close enough and doesn't cause heap traffic.

llvm-svn: 50958

Chris Lattner 82146fa267 Simplify code by using SwitchInst::findCaseValue instead of reimplementing it.

Nick Lewycky 4d43d3c72c Remove 'unwinds to' support from mainline. This patch undoes r47802 r47989

 2008-04-24 00:21:50 +00:00
Chris Lattner 12f1e007f7 Don't replace multiple result of calls with undef, 
sccp tracks getresult values, not call values in this
case.

Chris Lattner 769203cb03 code cleanup, no functionality change. 
llvm-svn: 50201
 2008-04-24 00:16:28 +00:00
Chris Lattner 5a58a4dc6d Rewrite multiple return value handling in SCCP. Before, the -sccp pass 
would turn every getresult instruction into undef.  This helps with
rdar://5778210

Dan Gohman 9988569af8 Don't include <map> in Pass.h, which doesn't need it. This requires 
adding <map> to many files that actually do need it.
