Devang Patel 593bf9ceb3 Handle multiple split conditions. 
llvm-svn: 40941
 2007-08-08 21:02:17 +00:00
Reid Spencer 8574ac95f0 Make it clear that getSTDIN returns null when stdin is empty. 
llvm-svn: 40940
 2007-08-08 20:02:20 +00:00
Reid Spencer 155533cf73 Make getSTDIN return null if the standard input is empty, as the header file 
documentation implies and as its uses depend.

llvm-svn: 40939
 2007-08-08 20:01:58 +00:00
Reid Spencer 8609c06956 Allow the filename "-" to be a place holder for stdin. This allows directing 
stdin through llvm-ld and llvm-link.

Owen Anderson 680862880d Global values also don't undead-ify pointers in our dead alloca's set.

Owen Anderson ddf4aee543 Make handleEndBlock significantly faster with one trivial improvement, 
and one hack to avoid hitting a bad case when the alias analysis is imprecise.

llvm-svn: 40935
 2007-08-08 18:38:28 +00:00
Owen Anderson 50df9685b0 Small improvement: if a function doesn't access memory, we don't need to scan 
it for potentially undeading pointers.

 2007-08-08 17:58:56 +00:00
Owen Anderson 52aaabf74d Add some comments, remove a dead argument, and simplify some control flow. 
No functionality change.

Chris Lattner 87f4836184 now that implicit conversions are explicit, we can eliminate 
EmitUsualArithmeticConversions.

 2007-08-08 17:49:18 +00:00
Steve Naroff 4bc57c0de7 Add support for __builtin_classify_type(). This builtin function isn't "public", however 
it is used by "tgmath.h" (so we need to support it). It might also come in handy when
developing the overloaded function macros for OpenCU.

Next check-in will make this an integer constant expression...

Chris Lattner 5ebb2fed89 now that implicit conversions are explicit, we can eliminate 
EmitExprWithUsualUnaryConversions.

Chris Lattner d1fd0db2ae eliminate redundant conditions from the signless types conversion.

Chris Lattner 7574ef3ac4 Handle functions with no name better.

Evan Cheng d771b793fe Adding kill info to val#. 
llvm-svn: 40925
 2007-08-08 07:03:29 +00:00
Chris Lattner 785f9986bd significantly speed up constant folding of calls (and thus all clients that use 
ConstantFoldInstruction on calls) by avoiding Value::getName().  getName() constructs
and returns an std::string, which does heap allocation stuff.  This slightly speeds up
instcombine.

llvm-svn: 40924
 2007-08-08 06:55:43 +00:00
Chris Lattner 415750e132 Speed up updateDFSNumbers with two observations: 
1. domtree is a tree, not a graph.  There is no need to avoid revisiting nodes with a set.
2. the worklist can contain the child iterator pointers so we don't get N^2 rescanning of children.

This speeds up updateDFSNumbers significantly, making it basically free.  On the testcase in PR1432,
this speeds up loopsimplify by another 3x, dropping it from the 12th most expensive pass to the to
the 30th. :)  It used to be #1.

Owen Anderson b17ab03081 A few more small cleanups. 
llvm-svn: 40922
 2007-08-08 06:06:02 +00:00
Evan Cheng 103947125c Clean up and bug fix. 
llvm-svn: 40921
 2007-08-08 05:56:18 +00:00
Chris Lattner c63d4c2e4e reimplement dfs number computation to be significantly faster. This speeds up 
natural loop canonicalization (which does many cfg xforms) by 4.3x, for 
example.  This also fixes a bug in postdom dfnumber computation.

 2007-08-08 05:51:24 +00:00
Owen Anderson 0aecf0ebef First round of cleanups from Chris' feedback. 
llvm-svn: 40919
 2007-08-08 04:52:29 +00:00
Evan Cheng a8c2f38617 - Each val# can have multiple kills. 
- Fix some minor bugs related to special markers on val# def. ~0U means
  undefined, ~1U means dead val#.

llvm-svn: 40916
 2007-08-08 03:00:28 +00:00
Devang Patel 68de1ae816 Embrace patch review feedback. 
llvm-svn: 40915
 2007-08-08 01:51:27 +00:00
Evan Cheng c236617ea0 Remove a dead assertion. 
llvm-svn: 40914
 2007-08-08 01:00:21 +00:00
Evan Cheng 0d0fee269a - LiveInterval value#'s now have 3 components: def instruction #, 
kill instruction #, and source register number (iff the value# is defined by a
copy).
- Now def instruction # is set for every value#, not just for copy defined ones.
- Update some outdated code related inactive live ranges.
- Kill info not yet set. That's next patch.

llvm-svn: 40913
 2007-08-07 23:49:57 +00:00
Devang Patel c7e53bdcfd Fix new compare instruction's signness. Caught by Chris during review.

Steve Naroff 773df5cf30 Move the function/array conversion for ParmVarDecl's from Sema::ParseIdentifierExpr() 
to Sema::ParseParamDeclarator(). After discussing this with Chris, we decided this
approach has more immediate benefit (though we loose some information in the AST). 
The comment below should describe more (if interested).

Dale Johannesen a47f7d7cfd Long double patch 8 of N: make it partially work in 
SSE mode (all but conversions <-> other FP types, I think):
>>Do not mark all-80-bit operations as "Requires[FPStack]"
(which really means "not SSE").
>>Refactor load-and-extend to facilitate this.
>>Update comments.
>>Handle long double in SSE when computing FP_REG_KILL.

Dale Johannesen 57c6ac5fe5 Long double patch 7 of N, unless I lost count:). 
Last x87 bits for full functionality (not
thoroughly tested, and long doubles do not work
in SSE modes at all - use -mcpu=i486 for now)
