2008-07-17Fix for codegen crash on multibit bool bitfield initializationDaniel Dunbar
<rdar://problem/6078606> git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53737 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-21"this patch adds code generation hooks for Objective-C constant strings. It ↵Chris Lattner
also modifies Sema so that Objective-C constant strings are treated as untyped objects if the interface for the constant string class can not be found. This is consistent with Apple GCC. I thought it was consistent with GNU GCC, since this was causing failures when trying to compile GNUstep with (GNU) GCC, but it appears that this is not the case when attempting to produce a simple test case to demonstrate it. Possibly there is a way of making the error go away, but I haven't found out what it is yet." Patch by David Chisnall! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@52599 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-07Fix crash with conversion to an address-space-qualified pointer. Bug Eli Friedman
reported on cfe-dev by Cédric Venet. Note that I seriously doubt that this perticular construct is useful, though: it's a pointer in an alternate address space pointing into unqualified address space. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@52076 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-06Reorganize this loop a bit so it doesn't crash for empty unions. Fixes Eli Friedman

2008-05-30Fix and enable generating general union initializers. Essentially, what Eli Friedman
this does is reconstruct the type for structs and arrays if the type wouldn't be compatible otherwise. The assertion about packing in the struct type reconstruction code sucks, but I don't see any obvious way to fix it. Maybe we need a general utility method to take a list of types and alignments and try to construct an unpacked type if possible? git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51785 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-30Fix constant vector init for initializer lists with an incomplete list Eli Friedman
of elements. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51769 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-30Some additions to constant initializer generation code. Adds Eli Friedman
bit-field initialization; ugly code, X86-only, but it works, at least for basic stuff. Separates/adds union initialization; currently disabled, though, because the struct/array code needs modifications to support elements of the wrong type. Fixes PR2381 and PR2309 with the bit-field initialization. And NetHack compiles and appears to work with a few tweaks (to work around the lack of transparent_union support, and clang being a bit strict about conflicting declarations). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51763 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-29More complete/correct implementation of the comparison operators for Eli Friedman
constant expressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51682 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-29Add codegen support for a few more kinds of initializer constant Eli Friedman
expressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51677 91177308-0d34-0410-b5e6-96231b3b80d8
2008-05-20Restructure constant structure init codegen so that it's possible to Eli Friedman
implement bitfield codegen (although I don't envy the person who implements it). This also prevents a crash on code like that from PR2309 (it's still broken, but it fails more gracefully). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@51285 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-15Remove FileVarDecl and BlockVarDecl. They are replaced by ↵Steve Naroff
VarDecl::isBlockVarDecl() and VarDecl::isFileVarDecl(). This is a fairly mechanical/large change. As a result, I avoided making any changes/simplifications that weren't directly related. I did break two Analysis tests. I also have a couple FIXME's in UninitializedValues.cpp. Ted, can you take a look? If the bug isn't obvious, I am happy to dig in and fix it (since I broke it). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49748 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-08Add support for C++ default arguments, and rework Parse-Sema Chris Lattner
interaction for function parameters, fixing PR2046. Patch by Doug Gregor! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49369 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-15Make a major restructuring of the clang tree: introduce a top-levelChris Lattner
lib dir and move all the libraries into it. This follows the main llvm tree, and allows the libraries to be built in parallel. The top level now enforces that all the libs are built before Driver, but we don't care what order the libs are built in. This speeds up parallel builds, particularly incremental ones. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48402 91177308-0d34-0410-b5e6-96231b3b80d8
