Tom Stellard [Mon, 20 Apr 2015 18:49:50 +0000 (18:49 +0000)]
configure: Add --enable-runtime-subnormal option

This makes it possible for runtime implementations to disable
subnormal handling at runtime.

When this flag is enabled, decisions about how to handle subnormals
in the library will be controlled by an external variable called
__CLC_SUBNORMAL_DISABLE.

Function implementations should use these new helpers for querying subnormal
support:
__clc_fp16_subnormals_supported();
__clc_fp32_subnormals_supported();
__clc_fp64_subnormals_supported();

In order for the library to link correctly with this feature,
users will be required to either:

1. Insert this variable into the module (if using the LLVM/Clang C++/C APIs).

2. Pass either subnormal_disable.bc or subnormal_use_default.bc to the
linker.  These files are distributed with liblclc and installed to
$(installdir).  e.g.:

llvm-link -o kernel-out.bc kernel.bc builtins-nosubnormal.bc subnormal_disable.bc

or

llvm-link -o kernel-out.bc kernel.bc builtins-nosubnormal.bc subnormal_use_default.bc

If you do not supply the --enable-runtime-subnormal then the library
behaves the same as it did before this commit.

In addition to these changes, the patch adds helper functions that
should be used when implementing library functions that need
special handling for denormals:

__clc_fp16_subnormals_supported();
__clc_fp32_subnormals_supported();
__clc_fp64_subnormals_supported();

This patch implements several improvements to the
module-loading support for the expression parser.

- It adds support for auto-loading modules referred
  to by a compile unit.  These references are
  currently in the form of empty translation units.
  This functionality is gated by the setting

  target.auto-import-clang-modules (boolean) = false

- It improves and corrects support for loading
  macros from modules, currently by textually
  pasting all #defines into the user's expression.
  The improvements center around including only those
  modules that are relevant to the current context -
  hand-loaded modules and the modules that are imported
  from the current compile unit.

- It adds an "opt-in" mechanism for all of this
  functionality.  Modules have to be explicitly
  imported (via @import) or auto-loaded (by enabling
  the above setting) to enable any of this
  functionality.

It also adds support to the compile unit and symbol
file code to deal with empty translation units that
indicate module imports, and plumbs this through to
the CompileUnit interface.

Finally, it makes the following changes to the test
suite:

- It adds a testcase that verifies that modules are
  automatically loaded when the appropriate setting
  is enabled (lang/objc/modules-auto-import); and

- It modifies lanb/objc/modules-incomplete to test
  the case where a module #undefs something that is
  #defined in another module.

Andrea Di Biagio [Mon, 20 Apr 2015 11:56:59 +0000 (11:56 +0000)]
[X86][FastIsel] Fix assertion failure when selecting int-to-double conversion (PR23273).

This fixes a regression introduced at revision 231243.
The target-independent selection algorithm in FastISel knows how to select
a SINT_TO_FP if the target is SSE but not AVX. That is because on X86, the
tablegen'd 'fastEmit' functions know how to select CVTSI2SSrr and CVTSI2SDrr.

Method X86FastISel::X86SelectSIToFP was therefore working under the
wrong assumption that the target was AVX. That assumption was incorrect since
we can have a target that is neither AVX nor SSE.

So, rather than asserting for the presence of AVX, we should have had an
early exit from 'X86SelectSIToFP' if the target was not AVX.
This patch fixes the issue replacing the invalid assertion with an early exit.

Thanks to Dimitry Andric for reporting this problem and for providing a small
reproducible testcase. Added test pr23273.ll.

Hal Finkel [Mon, 20 Apr 2015 00:01:30 +0000 (00:01 +0000)]
[InlineAsm] Remove EarlyClobber on registers that are also inputs

When an inline asm call has an output register marked as early-clobber, but
that same register is also an input operand, what should we do? GCC accepts
this, and is documented to accept this for read/write operands saying,
"Furthermore, if the earlyclobber operand is also a read/write operand, then
that operand is written only after it's used." For write-only operands, the
situation seems less clear, but I have at least one existing codebase that
assumes this will work, in part because it has syscall macros like this:

({                                                                         \
  register uint64_t r0 __asm__ ("r0") = (__NR_ ## name);                   \
  register uint64_t r3 __asm__ ("r3") = ((uint64_t) (arg0));               \
  register uint64_t r4 __asm__ ("r4") = ((uint64_t) (arg1));               \
  register uint64_t r5 __asm__ ("r5") = ((uint64_t) (arg2));               \
  __asm__ __volatile__                                                     \
  ("sc"                                                                    \
   : "=&r"(r0),"=&r"(r3),"=&r"(r4),"=&r"(r5)                               \
   :   "0"(r0),  "1"(r3),  "2"(r4),  "3"(r5)                               \
   : "r6","r7","r8","r9","r10","r11","r12","cr0","memory");                \
  r3;                                                                      \
})

Furthermore, with register aliases and subregister relationships that only the
backend knows about, rejecting this in the frontend seems like a difficult
proposition (if we wanted to do so). However, keeping the early-clobber flag on
the INLINEASM MI does not work for us, because it will cause the register's
live interval to end to soon (so it will not appear defined to be used as an
input).

Fortunately, fixing this does not seem hard: When forming the INLINEASM MI,
check to see if any of the early-clobber outputs are also inputs, and if so,
remove the early-clobber flag.

everything together *except* globals that are only ever used alone, that
is, those for which it's clearly non-profitable to merge with others.

In my testing, grouping by Function is too aggressive, but grouping by
BasicBlock is too conservative.  Anything in-between isn't trivially
available, so stick with Function grouping for now.

cl::opts are added for testing; both enabled by default.

A few of the testcases aren't testing the merging proper, but just
various edge cases when merging does occur.  Update them to use the
previous grouping behavior. Also, one of the tests is unrelated to
GlobalMerge; change it accordingly.
While there, switch to r234666' flags rather than the brutal -O3.

9 years ago[AArch64] Don't force MVT::Untyped when selecting LD1LANEpost.
Ahmed Bougacha [Fri, 17 Apr 2015 23:43:33 +0000 (23:43 +0000)]
[AArch64] Don't force MVT::Untyped when selecting LD1LANEpost.

The result is either an Untyped reg sequence, on ldN with N > 1, or
just the type of the input vector, on ld1.  Don't force Untyped.
Instead, just use the type of the reg sequence.

This mirrors the behavior of createTuple, which feeds the LD1*_POST.

The narrow code path wasn't actually covered by tests, because V64
insert_vector_elt are widened to V128 before the LD1LANEpost combine
has the chance to run, usually.

The only case where it does run on V64 vectors is if the vector ops
legalizer ran.  So, tickle the code with a ctpop.

Fixes PR23265.
