Eli Friedman 8547e1d129 Don't assume that the type of a FunctionDecl is a FunctionType; that 
assumption isn't accurate in the presence of typedefs.

Eli Friedman 6859a1b961 PR1893: Fix up the type of tentative definitions of incomplete array 
types so that they end up the correct size.

llvm-svn: 51787
 2008-05-30 20:39:54 +00:00
Eli Friedman 34994cbcbf Fix and enable generating general union initializers. Essentially, what 
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?

This fixes a crash on the included testcase (found in NetHack).

Eli Friedman 3c28524632 Fix an extremely subtle bug with pointer comparisons: they have to be 
unsigned because it's possible (at least in theory) to have

llvm-svn: 51681
 2008-05-29 15:09:15 +00:00
Eli Friedman 133e8040ca Rearrange EmitLValueForField a bit to work properly for _Bool bitfields 
in unions (we don't want to do the union-specific bitcast for 
bit-fields).

llvm-svn: 51678
 2008-05-29 11:33:25 +00:00
Eli Friedman 045bf4ff82 Add codegen support for a few more kinds of initializer constant 
expressions.

alignment and alignment attributes.

 2008-05-29 11:10:27 +00:00
Eli Friedman d72a9624a1 Tentative declarations are supposed to have common linkage, not weak. 
This change makes clang generate the same thing as llvm-gcc.

llvm-svn: 51674
 2008-05-29 11:03:17 +00:00
Eli Friedman 5a6d0ede91 Always use packed structs. This isn't really very nice, but there's 
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

Eli Friedman aee9e54dca Don't swap function decls, and add them to the scope as they are 
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
 2008-05-27 05:07:37 +00:00
Eli Friedman 078c963a31 Add a more reliable check for whether a static declaration has already

 2008-05-19 20:17:34 +00:00
Eli Friedman f23b6fa41f Fix the emission of expressions like char a[10] = "asdf"; previously, 
they were causing bad code to be emitted.  There are two fixes here: one 
makes sure we emit a string that is long enough, and one makes sure we 
properly handle string initialization in init lists.

llvm-svn: 51259
 2008-05-19 17:51:16 +00:00
Eli Friedman f2442dcc8d Fix support for _Bool bitfields. The issue is that the bitfield width 
used for _Bool is not the same as the primitive width (which for _Bool 
is 1 bit).  The load and store changes add some casts to make the 
types consistent.  The EmitLValue changes make sure that the pointer is 
of an appropriate type for loading the bitfield.

This isn't perfect, but it's an improvement, and getting everything 
right depends on actually laying out structs in an ABI-compliant way.

Eli Friedman a1b4ed8003 Implementation of __builtin_shufflevector, a portable builtin capable of 
expressing the full flexibility of the LLVM shufflevector instruction.  
The expected immediate usage is in *mmintrin.h, so that they don't 
depend on the mess of gcc-inherited (and not completely implemented)
shuffle builtins.

Chris Lattner 73669defed remove the 'unused static' diagnostic from codegen. This should be 
reimplemented in Sema someday.  This is tracked in PR2236.  Until then
disabling it removes some bogus diagnostics (see 2236).

Chris Lattner e799eb5daa Fix PR2081 (problems codegen'ing some recursive structures) patch 
by Lauro Venancio!

llvm-svn: 49144
 2008-04-03 05:50:42 +00:00
Chris Lattner a21ad8058a Fix several bugs in array -> pointer decomposition. 
First, we got several CVR propagation cases wrong, which Eli pointed
out in PR2039.

Second, we didn't propagate address space qualifiers correctly, leading
to incorrect lowering of code in CodeGen/address-space.c.

Third, we didn't uniformly propagate the specifier in the array to the
pointer ("int[restrict 4]" -> "int *restrict").

This adds an ASTContext::getArrayDecayedType member that handles the 
non-trivial logic for this seemingly simple operation.

Chris Lattner b5eda6253b pull .ll and .bc writing out of the ASTConsumer destructors into some top

emit into foo.ll instead of stdout.  Use "clang foo.c -emit-llvm -o -" or 
"clang < foo.c -emit-llvm" to get the old behavior.

Steve Naroff f727faf2ed Explicitly set the string literal type from "char *" to "constant array of char". 
At this point, I am fairly certain the front-end is correct. Unfortunately, the back-end is still unhappy.

That said, I've commented out the two lines in globalinit.c that are causing problems.

Chris, please have a look...thanks!
