Bruno Cardoso Lopes 129b4cc9ec Revert x86_64 ABI changes until I have time to check the items raised by Eli. 
llvm-svn: 134765
 2011-07-08 22:57:35 +00:00
Bruno Cardoso Lopes 308d7423a9 Add support for AVX 256-bit in the x86_64 ABI (as in the 0.99.5 draft) 
llvm-svn: 134754
 2011-07-08 22:18:40 +00:00
Eli Friedman 1310c68bb0 Don't use x86_mmx where it isn't necessary. 
The start of some work on getting -mno-mmx working the way we want it to.

Eli Friedman 4774b7e456 We don't pass classes with a copy-constructor or destructor byval, so the address takes up an integer register (if one is available). Make sure the x86-64 ABI implementation takes that into account properly. 
The fixed implementation is compatible with the implementation both gcc and llvm-gcc use.

rdar://9686430 . (This is the issue that was reported in the thread "[LLVMdev] Segfault calling LLVM libs from a clang-compiled executable".)

John McCall 31168b077c Automatic Reference Counting. 
Language-design credit goes to a lot of people, but I particularly want
to single out Blaine Garst and Patrick Beard for their contributions.

Compiler implementation credit goes to Argyrios, Doug, Fariborz, and myself,
in no particular order.

Akira Hatanaka b579fe5f15 Add stuff for o32 ABI conformance.

 2011-06-02 00:09:17 +00:00
Chris Lattner e76b95ae15 make the x86-32 backend specify a byval alignment, even when the 
code generator will do it.  With this patch, clang compiles the example
in PR9794 to not have an alloca temporary.

llvm-svn: 131881
 2011-05-22 23:35:00 +00:00
Chris Lattner 44c2b90556 Fix x86-64 byval passing to specify the alignment even when the code 
generator will give it something sufficient.  This is important because
the mid-level optimizer doesn't know what alignment is required otherwise.

Justin Holewinski bd4a3c03ff PTX: Add default PTX calling conventions 
llvm-svn: 129987
 2011-04-22 11:10:38 +00:00
John McCall e0fda7377e The 0.98 revision of the x86-64 ABI clarified a lot of things, some 
of which break strict compatibility with previous compilers.  Implement
one of them and then immediately opt out on Darwin.

Anton Korobeynikov 231e875b5c Implement ARM pcs attribute. Basically it's another way of calling convention selection (AAPCS or 
AAPCS+VFP), similar to fastcall / stdcall / whatevercall seen on x86.

In particular, all library functions should always be AAPCS regardless of floating point ABI used.

llvm-svn: 129534
 2011-04-14 20:06:49 +00:00
Sandeep Patel 45df3dd3fe Set AAPCS-VFP calling convention accordingly and hard float ABI command handling.

Jay Foad 20c0f02cc5 Remove PHINode::reserveOperandSpace(). Instead, add a parameter to

Bill Wendling ec9d2633f1 When we adjust the inline ASM type, we need to take into account an early 
clobber with the 'y' constraint. Otherwise, we get the wrong return type and an
assert, because it created a '<1 x i64>' vector type instead of the x86_mmx
type.

NAKAMURA Takumi f8a6e802f9 lib/CodeGen/TargetInfo.cpp: On Win64, arg i128 should be emitted as INDIRECT. 
mingw-w64's i128 tweak should be done with x86_64-mingw32.

NAKAMURA Takumi 31ea2f14bc Triple::MinGW64 is deprecated and removed. We can use Triple::MinGW32 instead. 
No one uses *-mingw64. mingw-w64 is represented as {i686|x86_64}-w64-mingw32.

NAKAMURA Takumi bd91f50190 lib/CodeGen/TargetInfo.cpp: Add Win64 calling conversion. 
FIXME: It would be incompatible to Microsoft's in one point.
On mingw64-gcc, {i128} is expanded for args and returned as {rax, rdx}.

Bill Wendling c7c9be661f Temporarily revert r116684. It was causing failures with 
Clang :: CodeGen/x86_32-arguments-darwin.c
    Clang :: CodeGen/x86_32-arguments-linux.c

Bill Wendling 812f4b123e The "gcc.dg/compat/vector-1 -m32" test was broken after the MMX rewrite. The 
function parameters weren't converted to use the correct type (x86_mmx). Add a
check, similar to the one in llvm-gcc, to see if we need the x86_mmx type for
that function parameter. If so, it coerces the type to be that.

Chris Lattner a09e8efd1f Per discussion with Sanjiv, remove the PIC16 target from mainline. When/if 
it comes back, it will be largely a rewrite, so keeping the old codebase
in tree isn't helping anyone.
