John McCall f3735e01ce Restore the lvalue-to-rvalue conversion patch with a minimal fix. 
llvm-svn: 120555
 2010-12-01 04:43:34 +00:00
Chris Lattner b85025fedd add some infrastructure that will let us codegen 
http://llvm.org/bugs/show_bug.cgi?id=279#c3 better.

No functionality change yet.

Chris Lattner 46a7ad7605 get some i32/i8/i1 constants from Builder, which is much less painful than 
using ConstantInt::get.

John McCall 5a39bd2443 A CGRecordLayout object persists. Since its contained types may 
refer to opaque types, they must be held via PATypeHolders.  I'm
not sure why this hasn't blown up before.

John McCall 4f22c9de48 L-value to r-value conversion is not ready for prime-time.

 2010-11-30 17:58:55 +00:00
John McCall 824fd1dcff Introduce an r-value to l-value cast kind. I'm not promising anything 
about the reliability of this yet.

Anders Carlsson 0c75b49dc1 Fix a (probably very old) regression where we weren't using the typedef name for anonymous tag types. 
llvm-svn: 120113
 2010-11-24 21:05:09 +00:00
Anders Carlsson 0e4dfebe63 Revert r120110. We don't want to call ConvertType from within getCGRecordLayout. 
llvm-svn: 120112
 2010-11-24 20:22:04 +00:00
Anders Carlsson 449bbc5bde Use ConvertType instead of ConvertTagDeclType, since ConvertType will assign a name to the type.

 2010-11-24 19:52:29 +00:00
Anders Carlsson 63e0f2050f Make CodeGenTypes::getCGRecordLayout compute the layout lazily if it doesn't exist. This matches ASTContext::getASTRecordLayout and is less confusing. 
llvm-svn: 120107

Argyrios Kyrtzidis d004064864 Refactoring of Diagnostic class. 
-Move the stuff of Diagnostic related to creating/querying diagnostic IDs into a new DiagnosticIDs class.
-DiagnosticIDs can be shared among multiple Diagnostics for multiple translation units.
-The rest of the state in Diagnostic object is considered related and tied to one translation unit.
-Have Diagnostic point to the SourceManager that is related with. Diagnostic can now accept just a
   SourceLocation instead of a FullSourceLoc.
-Reflect the changes to various interfaces.

John McCall 7decc9e4ea Calculate the value kind of an expression when it's created and 
store it on the expression node.  Also store an "object kind",
which distinguishes ordinary "addressed" l-values (like
variable references and pointer dereferences) and bitfield,
@property, and vector-component l-values.

Currently we're not using these for much, but I aim to switch
pretty much everything calculating l-valueness over to them.
For now they shouldn't necessarily be trusted.

Chris Lattner 11feaf5921 When forming the !srcloc mdnode for an inline asm, add the SourceLocations 
of all the lines of the inline asm.  With the refactoring and enhancement
of the backend, we can now reports errors on the correct source line when
an asm contains multiple lines of text.  For something like this:

void foo() {
  asm("push %rax\n"
      ".code32\n");
}

we used to get this: (note that the line 4 in t.c isn't helpful)

t.c:4:7: error: warning: ignoring directive for now
  asm("push %rax\n"
      ^
<inline asm>:2:1: note: instantiated into assembly here
.code32
^

now we get:

t.c:5:8: error: warning: ignoring directive for now
      ".code32\n"
       ^
<inline asm>:2:1: note: instantiated into assembly here
.code32
^

Note that we're pointing to line 5 properly now.  This implements
rdar://7839391 - inline asm errors should point to the right line in the asm
and makes the error message in PR8595 much less confusing.

John McCall 4f29b49de1 Support compound complex operations as l-values in C++. Add a test 
case based on CodeGen/volatile-1.c which tests the current C++
semantics, and note the many, many places we fall short of them.

Fariborz Jahanian a3e54bd33e Implements __block API for c++ objects. There is still 
issue with runtime which I am discussing it with Blaine.
This is wip (so no test yet).

llvm-svn: 119368
 2010-11-16 19:29:39 +00:00
John McCall 07bb19667a Simplify some complex emission and implement correct semantics for 
assignment to volatiles in C.  This in effect reverts some of mjs's
work in and around r72572.  Basically, the C++ standard is quite
clear, except that it lies about volatile behavior approximating
C's, whereas the C standard is almost actively misleading.
