* A couple minor fixes to make debug info usable for arbitrary code: don't Eli Friedman2008-05-292-1/+8
| | | | | | | | emit incomplete types, because they crash llc, and always use the logical location as the current location so we don't crash doing invalid queries on CurLoc. llvm-svn: 51675
* Tentative declarations are supposed to have common linkage, not weak. Eli Friedman2008-05-292-2/+2
| | | | | | This change makes clang generate the same thing as llvm-gcc. llvm-svn: 51674
* Always use packed structs. This isn't really very nice, but there's Eli Friedman2008-05-293-21/+15
| | | | | | | | | | | | | nothing fundamentally wrong with it. Emitting unpacked structs where possible is more work for almost no practical benefit. We'll probably want to fix it at some point anyway, but it's low priority. The issue with long double in particular is that LLVM thinks an X86 long double is 10 bytes, while clang considers it for all purposes to be either 12 or 16 bytes, depending on the platform, even in a packed struct. llvm-svn: 51673

* Don't swap function decls, and add them to the scope as they are Eli Friedman2008-05-274-68/+17
| | | | | | | | | | | | | encountered. Mixing up the decls is unintuitive, and confuses the AST destruction code. Fixes PR2360. Note that there is a need to look up the characteristics and declarations of a function associated with a particular name or decl, but the original swapping code doesn't solve it properly. http://lists.cs.uiuc.edu/pipermail/cfe-dev/2008-May/001644.html is one suggestion for how to fix that. llvm-svn: 51584
* Add a more reliable check for whether a static declaration has already Eli Friedman2008-05-272-17/+17
| | | | | | | been used. In preparation for the fix to PR2360, but also a minor bug in its own right. llvm-svn: 51583
* Stop leaking the main Sema object. (Leak found using valgrind.)Eli Friedman2008-05-271-2/+3
| | | | llvm-svn: 51580
* Stop leaking the target data. (Leak found with valgrind.)Eli Friedman2008-05-271-0/+1
| | | | llvm-svn: 51579
* Generalize the float type generation code, and specifically fix the Eli Friedman2008-05-272-5/+23
| | | | | | codegen of X86 long double. llvm-svn: 51578
* Implementation of gcc mode attribute; this is significant because Eli Friedman2008-05-277-1/+169
| | | | | | | | | | it fixes PR2204. Not too much to say about the implementation; it works in a similar way to the vector size attribute. At some point, we need to modify the targets to provide information about the appropriate types. llvm-svn: 51577
* Rewrite struct/union layout. This is mostly cleanup; this might also fix Eli Friedman2008-05-271-192/+80
| | | | | | | | | a few bugs, but I don't know of any in particular. This has good effects besides cleanup, though: it also should make it easier to implement the aligned and packed attributes, and also target-specific struct layouts, because the code won't have to be duplicated in codegen. llvm-svn: 51576
* Stop leaking the TUDecl.Eli Friedman2008-05-271-0/+2
| | | | llvm-svn: 51575
* Change diagnostic per suggestion, to make it a bit clearer what is Eli Friedman2008-05-274-5/+5
| | | | | | happening. llvm-svn: 51574
* Emit memmove, not memcpy, for structure copies; this is unfortunately Eli Friedman2008-05-263-4/+18
| | | | | | | | | | | | | | | | | required for correctness in cases of copying a struct to itself or to an overlapping struct (itself for cases like *a = *a, and overlapping is possible with unions). Hopefully, this won't end up being a perf issue; LLVM *should* be able to optimize memmove to memcpy in a lot of cases, and for small copies the generated code *should* be mostly comparable. (In reality, LLVM is currently horrible at optimizing memmove, but that's a bug, not a fundamental issue.) gcc currently generates wrong code; that's http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32667. llvm-svn: 51566
* Fix for PR2001. I'm not really fond of it, but it is correct (unless Eli Friedman2008-05-251-1/+10
| | | | | | | | someone tries to make a bitfield volatile?). Not sure how to write a test; any suggestions? llvm-svn: 51558
* Count the number of initializable members correctly in structs/unions Eli Friedman2008-05-252-2/+12

* Diagnose implicit init list for empty aggregate, like struct {}. Fixes Eli Friedman2008-05-253-0/+13
| | | | | | PR2151 (by not creating the empty implicit init list). llvm-svn: 51556

| | | | | | | | | http://llvm.org/viewvc/llvm-project/cfe/trunk/lib/Sema/SemaDecl.cpp?rev=51498&r1=51497&r2=51498&view=diff Turns out that there are multiple places where a redefinition diagnostic can be emitted. A cleaner solution (without touching Sema) is to have the Driver turn off these diagnostics. (will submit this patch soon) llvm-svn: 51502
