* Check Attribute::NoInline.Devang Patel2008-11-051-4/+2
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58742 91177308-0d34-0410-b5e6-96231b3b80d8
* Add InlineCost class for represent the estimated cost of inlining aDaniel Dunbar2008-10-301-5/+9
| | | | | | | | | | function. - This explicitly models the costs for functions which should "always" or "never" be inlined. This fixes bugs where such costs were not previously respected. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58450 91177308-0d34-0410-b5e6-96231b3b80d8
* Rename isWeakForLinker to mayBeOverridden. Use itDuncan Sands2008-09-291-5/+9
| | | | | | | | instead of hasWeakLinkage in a bunch of optimization passes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56782 91177308-0d34-0410-b5e6-96231b3b80d8
* Implement function notes as function attributes. Devang Patel2008-09-261-1/+1
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56716 91177308-0d34-0410-b5e6-96231b3b80d8
* Large mechanical patch.Devang Patel2008-09-251-1/+1
| | | | | | | | | | | | | | | | | s/ParamAttr/Attribute/g s/PAList/AttrList/g s/FnAttributeWithIndex/AttributeWithIndex/g s/FnAttr/Attribute/g This sets the stage - to implement function notes as function attributes and - to distinguish between function attributes and return value attributes. This requires corresponding changes in llvm-gcc and clang. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56622 91177308-0d34-0410-b5e6-96231b3b80d8
* Put FN_NOTE_AlwaysInline and others in FnAttr namespace.Devang Patel2008-09-241-1/+1

* Move FN_NOTE_AlwaysInline and other out of ParamAttrs namespace.Devang Patel2008-09-231-1/+1
| | | | | | | Do not check isDeclaration() in hasNote(). It is clients' responsibility. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56524 91177308-0d34-0410-b5e6-96231b3b80d8
* Use parameter attribute store (soon to be renamed) forDevang Patel2008-09-231-1/+1
| | | | | | | | Function Notes also. Function notes are stored at index ~0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@56511 91177308-0d34-0410-b5e6-96231b3b80d8
* Add hasNote() to check note associated with a function.Devang Patel2008-09-221-1/+1

* Handle "always inline" note during inline cost analysis.Devang Patel2008-09-031-0/+3

* Inliner tweak. Function calls should cost more than one instruction!Evan Cheng2008-07-171-0/+5

* If a function calls setjmp, never inline it into other functions. This isChris Lattner2008-07-141-1/+23
| | | | | | | | a hack around the fact that we don't represent the CFG correctly for sj/lj. It fixes PR2486. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53540 91177308-0d34-0410-b5e6-96231b3b80d8
* simplify some code, shuffle and insertelt always return a vector.Chris Lattner2008-07-141-2/+1

* Adjust inline cost computation to be less aggressive.Evan Cheng2008-04-241-2/+2
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@50222 91177308-0d34-0410-b5e6-96231b3b80d8
* 1. Drop default inline threshold back down to 200.Evan Cheng2008-04-011-8/+13
| | | | | | | | 2. Do not use # of basic blocks as part of the cost computation since it doesn't really figure into function size. 3. More aggressively inline function with vector code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49061 91177308-0d34-0410-b5e6-96231b3b80d8
* Increasing the inline limit from (overly conservative) 200 to 300. Given ↵Evan Cheng2008-03-241-5/+29
| | | | | | | | | each BB costs 20 and each instruction costs 5, 200 means a 4 BB function + 24 instructions (actually less because caller's size also contributes to it). Furthermore, double the limit when more than 10% of the callee instructions are vector instructions. Multimedia kernels tend to love inlining. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48725 91177308-0d34-0410-b5e6-96231b3b80d8

This interface allows clients to inline bunch of functions with module level call graph information.:wq git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40486 91177308-0d34-0410-b5e6-96231b3b80d8
