Eric Christopher af6431077c Add support for AVX registers to clang inline asm. Add a small testcase 
and update the Sema testcase with a register that we won't hit for a while
I hope.

Fixes rdar://10510405

Eli Friedman bfd5addf4c When we're passing a vector with an illegal type through memory on x86-64, use byval so we're sure the backend does the right thing. Fixes va_arg with illegal vectors and an obscure ABI mismatch with __m64 vectors.

Eli Friedman f37bd2f2f1 Don't use a varargs convention for calls unprototyped functions where one of the arguments is an AVX vector.

Tanya Lattner 71f1b2dcd4 Correct the code generation for function arguments of vec3 types on x86_64 when they are greater than 128 bits. This was incorrectly coercing things like long3 into a double2. 
Add test case.

Benjamin Kramer ddbb2b85ab CodeGen: allow __asm renaming on static local variables.

llvm-svn: 144972
 2011-11-18 04:01:36 +00:00
Eli Friedman 0b3f201b61 Fix the meaning of an "empty" record for the case of a zero-length array. Use isEmptyRecord for arguments on x86-32; there are structs of size 0 which don't count as empty. 
llvm-svn: 144971
 2011-11-18 03:47:20 +00:00
Eli Friedman a1748564b4 Make va_arg on x86-64 compute alignment the same way as argument passing.

 2011-11-18 01:32:26 +00:00
Eli Friedman ee94534662 Simplify code for returning a struct for Darwin x86-32 ABI. Use a better type for a function returning a struct containing only a pointer. Handle the edge case of a struct containing only a float or double plus some dead padding instead of asserting.

llvm-svn: 143418
 2011-11-01 02:26:36 +00:00
Eli Friedman fcec630a57 Fix the representation of wide strings in the AST and IR so that it uses the native representation of integers for the elements. This fixes a bunch of nastiness involving 
treating wide strings as a series of bytes.

Patch by Seth Cantrell.

Peter Collingbourne f1d76db466 Add support for lazily linking bitcode files (using a new 
-mlink-bitcode-file flag), and more generally llvm::Modules, before
running optimisations.

Nick Lewycky b25abd1a54 Move these test from checking assembly to checking LLVM IR. Should fix fallout 
from r143097.

llvm-svn: 143052
 2011-10-26 20:46:27 +00:00
Rafael Espindola c594135b68 Fix pr9614 by not emitting an available_externally function when it calls 
itself via an asm label.

available_externally functions are supposed to correspond to an external
function, and that is not the case in the examples in pr9614.

Eric Christopher 4b4beb2fe7 Fix PR11073 by adding the argument type information to the decl we construct 
for the function type. Update a testcase accordingly.

Nick Lewycky ba743b75cb Take DW_AT_comp_dir from $PWD when it's present and starts with a '/'. This is 
closer to what GCC does, except that GCC also checks that the inodes for $PWD
and '.' match.

Eli Friedman cc66a2b067 Add missing newline.

 2011-10-17 21:48:31 +00:00
Eli Friedman a4c2602b71 Initial implementation of __atomic_is_lock_free. The input is the size of an atomic type rather than an atomic type itself just to save some implementation pain; I can change that if it seems worthwhile. 
I think this is the last hook needed for <atomic> besides defines for ATOMIC_CHAR_LOCK_FREE and friends.

llvm-svn: 142281
 2011-10-17 21:44:23 +00:00
Tanya Lattner 49b3841398 The comparison of two vectors should return a signed result. hasIntegerRepresentation() used to always return false for vectors, but since it was changed, it also 
changed the return type of a compare of two unsigned vectors to be unsigned. This patch removes the check for hasIntegerRepresentation since its not needed and returns the appropriate signed type.
I added a new test case and updated exisiting test cases that assumed an unsigned result.

-std=c++0x. Patch by Ahmed Charles!

Eric Christopher 7cdf948601 Recommit: 
Start handling debug line and scope information better:

    Migrate most of the location setting within the larger API in CGDebugInfo and
    update a lot of callers.
    Remove the existing file/scope change machinery in UpdateLineDirectiveRegion
    and replace it with DILexicalBlockFile usage.

    Finishes off the rest of rdar://10246360

after fixing a few bugs that were exposed in gdb testsuite testing.

Rafael Espindola 2d21ab024e Add returns_twice to functions that are known to return twice. This implements 
the same behavior of gcc by keeping the attribute out of the function type.
