2009-01-08Do not inline functions with (dynamic) alloca intoDale Johannesen
functions that don't already have a (dynamic) alloca. Dynamic allocas cause inefficient codegen and we shouldn't propagate this (behavior follows gcc). Two existing tests assumed such inlining would be done; they are hacked by adding an alloca in the caller, preserving the point of the tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61946 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-08ValueTracker can't assume that an alloca with no specified alignment Chris Lattner
will get its preferred alignment. It has to be careful and cautiously assume it will just get the ABI alignment. This prevents instcombine from rounding up the alignment of a load/store without adjusting the alignment of the alloca. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61934 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-08This implements the second half of the fix for PR3290, handlingChris Lattner
loads from allocas that cover the entire aggregate. This handles some memcpy/byval cases that are produced by llvm-gcc. This triggers a few times in kc++ (with std::pair<std::_Rb_tree_const_iterator <kc::impl_abstract_phylum*>,bool>) and once in 176.gcc (with %struct..0anon). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61915 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-08Fix failure messages in Verifier::PerformTypeCheck. The argument numbersBob Wilson
passed in to this function changed to support multiple return values, leading to some incorrect argument numbers in the failure messages. With this change, the ArgNo values used for return values and parameters are disjoint, and the new IntrinsicParam function translates those ArgNo values to strings that can be used in the messages. This also fixes a few places where PerformTypeCheck did not return false following calls to CheckFailed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61903 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-07Remove alloca tracking from nocapture analysis. Not onlyDuncan Sands
was it not very helpful, it was also wrong! The problem is shown in the testcase: the alloca might be passed to a nocapture callee which dereferences it and returns the original pointer. But because it was a nocapture call we think we don't need to track its uses, but we do. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61876 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-07Implement the first half of PR3290: if there is a store of an Chris Lattner
integer to a (transitive) bitcast the alloca and if that integer has the full size of the alloca, then it clobbers the whole thing. Handle this by extracting pieces out of the stored integer and filing them away in the SROA'd elements. This triggers fairly frequently because the CFE uses integers to pass small structs by value and the inliner exposes these. For example, in kimwitu++, I see a bunch of these with i64 stores to "%struct.std::pair<std::_Rb_tree_const_iterator<kc::impl_abstract_phylum*>,bool>" In 176.gcc I see a few i32 stores to "%struct..0anon". In the testcase, this is a difference between compiling test1 to: _test1: subl $12, %esp movl 20(%esp), %eax movl %eax, 4(%esp) movl 16(%esp), %eax movl %eax, (%esp) movl (%esp), %eax addl 4(%esp), %eax addl $12, %esp ret vs: _test1: movl 8(%esp), %eax addl 4(%esp), %eax ret The second half of this will be to handle loads of the same form. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@61853 91177308-0d34-0410-b5e6-96231b3b80d8
