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.

Sandeep Patel 45df3dd3fe Set AAPCS-VFP calling convention accordingly and hard float ABI command handling.

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.

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.

Clang does not wrap the vectors in structs anymore so this isn't needed.

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.

Daniel Dunbar 19964dbe3b IRgen/ABI/ARM: Return large vectors in memory.

 2010-09-23 01:54:32 +00:00
Daniel Dunbar b34b08098c IRgen/ABI/ARM: Trust the backend to pass vectors correctly for the given ABI. 
- Therefore, we can lower out the NEON wrapper structs and pass the vectors
   directly. This makes a huge difference in the cleanliness of the IR after
   optimization.
 - I will trust, but verify, via future ABITest testing (for APCS-GNU, at
   least).

Daniel Dunbar dd38fbc7fb IRgen/ABI/x86-32: Realign indirect arguments when the ABI requires us to pass 
them with a smaller alignment than the rest of codegen expects.

llvm-svn: 114115
 2010-09-16 20:42:06 +00:00
Daniel Dunbar 7b7c2937ef IRgen/ABI: Add support for realigning structures which are passed by indirect 
reference.

 2010-09-16 20:42:02 +00:00
Daniel Dunbar ed23de3348 IRgen/ABI/x86_32/Darwin: On Darwin, only structures with SSE vector types get passed 
with a non-default-stack-ABI-alignment (of 16).
 - This fixes the ABI convenient, but breaks codegen since we now have
   underaligned arguments. Marginal improvement overall though, and will be
   fixed in next commit.

 2010-09-16 20:42:00 +00:00
Daniel Dunbar 8a6c91ff76 IRgen/x86_32/Linux: Linux seems to align all stack objects to 4 bytes, unlike 
Darwin. Checked vs the handiest Linux llvm-gcc I had around, someone on Linux is
welcome to investigate more.

Chris Lattner d426c8eae3 fix rdar://8360877 a really nasty miscompilation in Boost.Xpressive 
caused by my ABI work.  Passing:

struct outer {
  int x;
  struct epsilon_matcher {} e;
  int f;
};

as {i32,i32} isn't safe, because the offset of the second element
needs to be at 8 when it is interpreted as a memory value.

Chris Lattner d774ae9ed1 fix 2xi16 to pass as i32 instead of <2 x i16>. The former passes in 
memory (as required) the later now passes in an xmm register.  This
fixes gcc.dg/compat/vector_1 on x86-32.

Chris Lattner 69e683fb35 vector of long and ulong are also classified as INTEGER in x86-64 abi,
