Dale Johannesen 8fc8a272e0 Don't assume a tail call can't reference a byval 
argument to the outer function, this isn't correct.

Dan Gohman 2cd8e38ab9 Teach AliasSetTracker about VAArgInst.

 2008-04-14 18:34:50 +00:00
Dan Gohman 5e6ce7bb33 In the special case, call the comparison function instead of 
manually performing the comparison. This allows the special
case to work correctly even in the case where someone is
experimenting with a different comparison function :-).

llvm-svn: 49670

wrong order.

 2008-03-30 18:02:00 +00:00
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.

llvm-svn: 48667
 2008-03-21 23:51:57 +00:00

 2008-03-18 22:22:53 +00:00
Scott Michel 08ef1b2bdb Dial down gcc's warnings: don't use 0UL when 0U suffices (and when the 
variables and methods themselves only use unsigned.)

llvm-svn: 48492
 2008-03-18 16:55:06 +00:00
Devang Patel 864970e9b6 Identify Analysis pass. 
Do not run analysis pass again if analysis info is still available.
This fixes PR1441.

Gabor Greif f77e6977a0 Fix http://llvm.org/bugs/show_bug.cgi?id=2104 by ordering lexicographically what gets printed. Be const-correct in PrintResults and uninline it too 
llvm-svn: 47712

llvm-svn: 47437
 2008-02-21 17:33:24 +00:00
Nick Lewycky 5a3db1406a Simplify this code, no functionality change. 
llvm-svn: 47434
 2008-02-21 09:14:53 +00:00
Nick Lewycky 839adb877a GlobalValues are Constants, remove redundant code. Also fix typo in a comment. 
llvm-svn: 47433
 2008-02-21 08:34:02 +00:00
Anton Korobeynikov 579f07135a Unbreak build with gcc 4.3: provide missed includes and silence most annoying warnings. 
llvm-svn: 47367
 2008-02-20 11:08:44 +00:00
Nick Lewycky b0a2f9513f Use getConstant for ConstantInts. 
llvm-svn: 47361
 2008-02-20 06:58:55 +00:00
Nick Lewycky 1c44ebcf86 Add 'umax' similar to 'smax' SCEV. Closes PR2003. 
Parse reversed smax and umax as smin and umin and express them with negative
or binary-not SCEVs (which are really just subtract under the hood).

Parse 'xor %x, -1' as (-1 - %x).

Remove dead code (ConstantInt::get always returns a ConstantInt).

Don't use getIntegerSCEV(-1, Ty). The first value is an int, then it gets
passed into a uint64_t. Instead, create the -1 directly from
ConstantInt::getAllOnesValue().

llvm-svn: 47360
 2008-02-20 06:48:22 +00:00
Duncan Sands eec73618af Fix a compiler warning. 
llvm-svn: 47328
 2008-02-19 09:28:48 +00:00
Owen Anderson d2d7c6b309 In addition to arguments passed to it, memcpy (and all other calls) can ModRef pointers that alias their arguments as well. This fixes PR2057. 
llvm-svn: 47317
 2008-02-19 06:47:18 +00:00
Chris Lattner 8ed77c41d8 don't bother calling getUnderlyingObject for non-pointers. 
llvm-svn: 47272
 2008-02-18 17:28:21 +00:00
Owen Anderson cc01ebbac6 Since we're not checking for the more general AllocationInst first, we need to explicitly check 
that Object is an Argument before casting it to one.

llvm-svn: 47268
 2008-02-18 10:11:00 +00:00
Owen Anderson bdf7ed9495 This check is not correct for mallocs, so exclude them earlier. 
llvm-svn: 47263
 2008-02-18 09:11:02 +00:00
Owen Anderson 57a98b7f4b Fix a comment, and a bug where we weren't applying the tail call logic in cases that failed the first test. 
llvm-svn: 47253
 2008-02-18 03:52:21 +00:00
Owen Anderson fa2ba5352f Fix bugs that Chris noticed in my last patch. 
llvm-svn: 47252
 2008-02-18 02:31:23 +00:00
Chris Lattner 8432cc662f bitcasts of pointers are always pointers. 
If we see a memcpy of a pointer, make sure to check later
uses of the pointer as well.

llvm-svn: 47250
 2008-02-18 02:11:28 +00:00
Owen Anderson 2e3edf193a Teach getModRefInfo that memcpy, memmove, and memset don't "capture" memory addresses. 
Also, noalias arguments are be considered "like" stack allocated ones for this purpose, because
the only way they can be modref'ed is if they escape somewhere in the current function.
