Chris Lattner 071a5e5649 Rename the intrinsic enum values for llvm.va_* from Intrinsic::va_* to 
Intrinsic::va*.  This avoid conflicting with macros in the stdlib.h file.

Chris Lattner 9e100fc3f7 Really, only if reopen 
llvm-svn: 12080
 2004-03-02 20:46:18 +00:00
Chris Lattner c8d23b19fb Correctly add an array marker on a node when appropriate! 
llvm-svn: 12055
 2004-03-01 19:02:54 +00:00
Chris Lattner 98f8ca4017 ADD MORE FUNCTIONS! 
llvm-svn: 11927
 2004-02-27 20:04:48 +00:00
Chris Lattner 5ef1638da2 Be a good little compiler and handle direct calls efficiently, even if there 
are beastly ConstantPointerRefs in the way...

llvm-svn: 11883
 2004-02-26 22:07:22 +00:00
Chris Lattner c8167b0e7e Add _more_ functions 
llvm-svn: 11862
 2004-02-26 03:43:08 +00:00
Chris Lattner fab2872b6c When building local graphs, clone the initializer for constant globals into each 
local graph that uses the global.

llvm-svn: 11850
 2004-02-25 23:31:02 +00:00
Chris Lattner 5e5e060618 Add a bunch more functions 
llvm-svn: 11847
 2004-02-25 23:06:40 +00:00
Chris Lattner 864c901444 Add a bunch more functions used by perlbmk 
llvm-svn: 11824
 2004-02-25 17:43:20 +00:00
Chris Lattner 9ccb1af08f Add support for 'rename' 
llvm-svn: 11813
 2004-02-24 22:17:00 +00:00
Chris Lattner 396cdaf067 Add support for remove, fwrite, and fread 
Also fix problem where we didn't check to see if a node pointer was null.
Though fclose(null) doesn't make a lot of sense, 300.twolf does it.

llvm-svn: 11810
 2004-02-24 22:02:48 +00:00
Chris Lattner 7b0368ee16 Add two missing returns, which caused us to be very pessimistic about the 
printf and scanf families!

llvm-svn: 11683
 2004-02-20 23:27:09 +00:00
Chris Lattner a061c3b25b Add support for some string functions, the scanf family, and sprintf 
llvm-svn: 11673
 2004-02-20 20:27:11 +00:00
Chris Lattner 0cb8855a1c Only spit out warning for functions that take pointers, not for sin and the like 
Add more special case handling for stdio functions.  I feel dirty, how about you?

llvm-svn: 11506
 2004-02-16 22:57:19 +00:00
Chris Lattner cedfcf5bca memset and bcopy and now unified by the llvm.memset intrinsic 
llvm-svn: 11503
 2004-02-16 18:37:40 +00:00
Chris Lattner 218eb798a2 No need to scan zero initializers. This should make DSA a bit faster. 
llvm-svn: 11471
 2004-02-15 05:53:42 +00:00
Chris Lattner d17e15eddd Add support for a bunch more functions 
llvm-svn: 11395
 2004-02-13 21:21:48 +00:00
Chris Lattner e00227248e Add support for fopen/fclose. Specifically with fopen, we were marking all of the 
operands as incomplete, though fopen is known to only read them.  This just adds
fclose for symmetry, though it doesn't gain anything.  This makes the dsgraphs for
181.mcf much more precise.

llvm-svn: 11390
 2004-02-13 20:05:32 +00:00
Chris Lattner 9761271f0f Restructure code to handle memcpy/memmove 
llvm-svn: 11374
 2004-02-13 16:09:54 +00:00
Chris Lattner 9ab85275ef Instead of callign removeTriviallyDeadNodes on the global graph every time 
removeDeadNodes is called, only call it at the end of the pass being run.
This saves 1.3 seconds running DSA on 177.mesa (5.3->4.0s), which is
pretty big.  This is only possible because of the automatic garbage
collection done on forwarding nodes.

 2004-02-08 01:51:48 +00:00
Chris Lattner 985282c78e This call is no longer needed now that merging does not produce garbage

Chris Lattner 567444309a Do not depend on index type to determine whether it is a structure or sequential index

Chris Lattner ab6895ea76 Implement a small optimization to handling of GEP's that are equivalent to casts. 
This results in substantially reduced collapsing for some testcases

Chris Lattner 12dd38aa99 Handle bzero and memset in the local analysis, because we were missing the fact 
that memset returns its argument!!

 2003-11-08 21:55:50 +00:00
Chris Lattner 2b9926fc8e All DSGraphs keep a reference to the targetdata they are created with. This is 
used to eliminate the hard coded, hacked in, sparc specific, global TargetData.
Changing the TargetData used to actually match the code fixes problems, and
eliminates a crash.

Chris Lattner 04d9cb6770 Switch from using CallInst's to represent call sites to using the LLVM 
CallSite class.  Now we can represent function calls by invoke instructions
too!

Chris Lattner 4853d162af * Changes to make NodeType be private to DSNode. 
* Add new MultiObject flag to DSNode which keeps track of whether or not
  multiple objects have been merged into the node, allowing must-alias info
  to be tracked.
