17309 ARM backend incorrectly lowers COPY_STRUCT_BYVAL_I32 for thumb1 targets

This commit implements the correct lowering of the
COPY_STRUCT_BYVAL_I32 pseudo-instruction for thumb1 targets.
Previously, the lowering of COPY_STRUCT_BYVAL_I32 generated the
post-increment forms of ldr/ldrh/ldrb instructions. Thumb1 does not
have the post-increment form of these instructions so the generated
assembly contained invalid instructions.

Passing the generated assembly to gcc caused it to complain with an
error like this:

  Error: cannot honor width suffix -- `ldrb r3,[r0],#1'

and the integrated assembler would generate an object file with an
invalid instruction encoding.

This commit contains a small test case that demonstrates the problem
with thumb1 targets as well as an expanded test case that more
throughly tests the lowering of byval struct passing for arm,
thumb1, and thumb2 targets.

11 years agox86: Move bitcasts outside concat_vector.
Jim Grosbach [Thu, 17 Oct 2013 02:58:06 +0000 (02:58 +0000)]
x86: Move bitcasts outside concat_vector.

Consider the following:

typedef unsigned short ushort4U __attribute__((ext_vector_type(4),
aligned(2)));
typedef unsigned short ushort4 __attribute__((ext_vector_type(4)));
typedef unsigned short ushort8 __attribute__((ext_vector_type(8)));
typedef int int4 __attribute__((ext_vector_type(4)));

int4 __bbase_cvt_int(ushort4 v) {
  ushort8 a;
  a.lo = v;
  return _mm_cvtepu16_epi32(a);
}

This generates the, not unreasonable, IR:
define <4 x i32> @foo0(double %v.coerce) nounwind ssp {
  %tmp = bitcast double %v.coerce to <4 x i16>
  %tmp1 = shufflevector <4 x i16> %tmp, <4 x i16> undef, <8 x i32> <i32
  %0, i32 1, i32 2, i32 3, i32 undef, i32 undef, i32 undef, i32 undef>

  ret <4 x i32> %tmp2
}

The problem is when type legalization gets hold of the v4i16. It
legalizes that by spilling to the stack, then doing a zero-extending
load. Things go even more silly from there, ending up with something
like:
_foo0:
  movsd %xmm0, -8(%rsp)       <== Spill to the stack.
  movq  -8(%rsp), %xmm0       <== Reload it right back out.
  pmovzxwd  %xmm0, %xmm1      <== Here's what we actually asked for.
  pblendw $1, %xmm1, %xmm0    <== We don't need this at all
  pmovzxwd  %xmm0, %xmm0      <== We already did this
  ret

The v8i8 to v8i16 zext intrinsic gives even worse results, with two
table lookups via pshufb instructions(!!).

To avoid all that, we can move the bitcasting until after we've formed
the wider (legal) vector type. Then our normal codegen flows along
nicely and we get the expected:
_foo0:
  pmovzxwd  %xmm0, %xmm0
  ret

Expose install_fatal_error_handler() through the C API.

- The C++ API involves a traditional void* opaque pointer for the fatal
error callback.  The C API doesn’t do this.  I don’t think that the void*
opaque pointer makes any sense since this is a global callback - there will
only be one of them.  So if you need to pass some data to your callback,
just put it in a global variable.

- The bindings will ignore the gen_crash_diag boolean.  I ignore it because
(1) I don’t know what it does, (2) it’s not documented AFAIK, and (3) I

Re-commit r192758 - MC: quote tricky symbol names in asm output

The reason this got reverted was that the @feat.00 symbol which was emitted
for every TU became quoted, and on cygwin/mingw we use the gas assembler which
couldn't handle the quotes.

This commit fixes the problem by only emitting @feat.00 for win32, where we use
clang -cc1as to assemble. gas would just drop this symbol anyway, so there is no
loss there.

With @feat.00 gone, there shouldn't be quoted symbols showing up on cygwin since
it uses the Itanium ABI, which doesn't put these funny characters in symbols.

Assert on duplicate registration. Don't depend on function pointer equality.

Before this patch we would assert when building llvm as multiple shared
libraries (cmake's BUILD_SHARED_LIBS). The problem was the line

if (T.AsmStreamerCtorFn == Target::createDefaultAsmStreamer)

which returns false because of -fvisibility-inlines-hidden. It is easy
to fix just this one case, but I decided to try to also make the
registration more strict. It looks like the old logic for ignoring
followup registration was just a temporary hack that outlived its
usefulness.

This patch converts the ifs to asserts, fixes the few cases that were
registering twice and makes sure all the asserts compare with null.

Thanks for Joerg for reporting the problem and reviewing the patch.

Summary:
Given a global array G[N], which is declared in this CU and has static initializer
avoid instrumenting accesses like G[i], where 'i' is a constant and 0<=i<N.

This eliminates ~1% of instrumentations on SPEC2006
