2010-05-04Emit the globals, metadata, etc. associated with static variables even whenJohn McCall
they're unreachable. This matters because (if they're POD, or if this is C) the scope containing the variable might be reachable even if the variable isn't. Fixes PR7044. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@103052 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-03Just bail out immediately when emitting an unreachable function-local staticJohn McCall

2010-03-19Change CodeGenModule to rely on the Module's symbol table instead ofJohn McCall
shadowing it in the GlobalDeclMap. Eliminates the string-uniquing requirement for mangled names, which should help C++ codegen times a little. Forces us to do string lookups instead of pointer lookups, which might hurt codegen times a little across the board. We'll see how it plays out. Removing the string-uniquing requirement implicitly fixes any bugs like PR6635 which arose from the fact that we had multiple uniquing tables for different kinds of identifiers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@99012 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-12Fix a rare corner case bug which exposed a serious block API generationFariborz Jahanian
when initialized variable is a byref block variable and is referenced recursively in the initializer (you guessed it, it is block implementation of fibonacci number). Fix, on the other hand is trvial, by generating the API for byref variable before API for its initializer. We will have this test added to our internal test suite as a clang-style test is not possible due to very convoluted IR sequence. Fixes radar 7745514. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98393 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-10set alignment on static locals properly, patch by Arnaud de Grandmaison!Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98204 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-09IRgen: Add CreateMemTemp, for creating an temporary memory object for a ↵Daniel Dunbar
particular type, and flood fill. - CreateMemTemp sets the alignment on the alloca correctly, which fixes a great many places in IRgen where we were doing the wrong thing. - This fixes many many more places than the test case, but my feeling is we need to audit alignment systematically so I'm not inclined to try hard to test the individual fixes in this patch. If this bothers you, patches welcome! PR6240. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95648 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-08Reapply r95393, without the change to CGExpr. I was wrong in assuming that theDaniel Dunbar
element type always matched the converted LLVM type for ExprType. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95596 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-05IRgen: Use hasAggregateLLVMType instead of isSingleValueType() for cases thatDaniel Dunbar
need to deal with aggregates specially; this is consistent with the rest of IRgen. Also, simplify EmitParmDecl and don't worry about using Decl::getNameAsString. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@95393 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-11Roll out ASTContext::getTypeSizeInChars(), replacing instances ofKen Dyck
"ASTContext::getTypeSize() / 8". Replace [u]int64_t variables with CharUnits ones as appropriate. Also rename RawType, fromRaw(), and getRaw() in CharUnits to QuantityType, fromQuantity(), and getQuantity() for clarity. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93153 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-18Change the return type of ASTContext::getTypeSizeInChars() from uint64_t to theKen Dyck
new opaque value type, CharUnits. This will help us avoid accidentally mixing quantities that are in bit and character units. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91689 91177308-0d34-0410-b5e6-96231b3b80d8
