2010-07-28fix some break statements to be formatted more consistently,Chris Lattner
remove some now-dead code. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109690 91177308-0d34-0410-b5e6-96231b3b80d8

don't get errors similar to PR7714 on the return path. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109689 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-28refactor the autosizing code, eliminating duplicationChris Lattner
and making Get8ByteTypeAtOffset always succeed and documented. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109685 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-28fix PR7714 by not referencing off the end of a struct when passed by value inChris Lattner
x86-64 abi. This also improves codegen as well. Some refactoring is needed of this code. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109681 91177308-0d34-0410-b5e6-96231b3b80d8

Tested by mi1-var-obj.exp in gdb testsuite. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109571 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-28When creating a jump destination, its scope should be the scope of theJohn McCall
enclosing normal cleanup, not the top of the EH stack. I'm *really* surprised this hasn't been causing more problems. Fixes rdar://problem/8231514. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109569 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-27Revert r109546, it broke linux build.Argyrios Kyrtzidis
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109550 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-27Merge PCHWriterDecl.cpp's isRequiredDecl and ↵Argyrios Kyrtzidis
CodeGenModule::MayDeferGeneration into a new function, DeclIsRequiredFunctionOrFileScopedVar. This function is part of the public CodeGen interface since it's essentially a CodeGen predicate that is also needed by the PCH mechanism to determine whether a decl needs to be deserialized during PCH loading for codegen purposes. This fixes current (and avoids future) codegen-from-PCH bugs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109546 91177308-0d34-0410-b5e6-96231b3b80d8

I knew this code duplication would bite me. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109463 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-24Untangle filename/dirname confusion. Store constructed strings on the side. ↵Devang Patel
Avoid use of Path.makeAbsolute(). DW_TAG_compile_unit uses two attributes DW_AT_name and DW_AT_comp_dir. Their expected values are: $ clang foo.c -g DW_AT_name - foo.c DW_AT_comp_dir - `pwd` $ clang one/two/foo.c -g DW_AT_name - one/two/foo.c DW_AT_comp_dir - `pwd` $ clang /tmp/one/foo.c -g DW_AT_name - /tmp/one/foo.c DW_AT_comp_dir - empty git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109303 91177308-0d34-0410-b5e6-96231b3b80d8

Diagnose attempts to do this under the GNU or fragile NeXT runtimes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109298 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-24Return type of a setter call caused byFariborz Jahanian
use of property-dot syntax using 'super' as receiver is 'void'. This fixes a bug in generating correct API for setter call. Fixes radar 8203426. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109297 91177308-0d34-0410-b5e6-96231b3b80d8

as well as some significant asymptotic inefficiencies with threading multiple jumps through deep cleanups. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109274 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-23There is no need to use separate dir name for AT_comp_dir attribute. Using ↵Devang Patel
absolute path for filename allows clients to query complete file location info from gdb breakpoints. Save constructed full file name. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109263 91177308-0d34-0410-b5e6-96231b3b80d8
2010-07-23Vectors are not integer types, so the type system should not classifyDouglas Gregor
them as such. Type::is(Signed|Unsigned|)IntegerType() now return false for vector types, and new functions has(Signed|Unsigned|)IntegerRepresentation() cover integer types and vector-of-integer types. This fixes a bunch of latent bugs. Patch from Anton Yartsev! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@109229 91177308-0d34-0410-b5e6-96231b3b80d8

2010-07-21Switch finally cleanups over to being lazy cleanups. We get basically nothingJohn McCall
from the laziness features here except better block ordering, but it removes yet another CleanupBlock use. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108990 91177308-0d34-0410-b5e6-96231b3b80d8

initializer of (). Make sure to use a simple memset() when we can, or fall back to generating a loop when a simple memset will not suffice.

a big deal, except that I want to eliminate the shared-code EH cleanups in preparation for a significant algorithmic fix. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@108973 91177308-0d34-0410-b5e6-96231b3b80d8
