When debugging test failures with -vv (or -v in the case of the

after concatenation for line continuations.

When reading the generated shell script, this also makes it easier to
locate the RUN line that produced each command.

To support reporting RUN line numbers in the case of the internal
shell, this patch extends the internal shell to support the null
command, ":", except pipelines are not supported.

To support reporting RUN line numbers in the case of windows cmd.exe
as the external shell, this patch extends -vv to set "echo on" instead
of "echo off" in bat files.  (Support for windows cmd.exe as a lit

Per discussion on the generic-abi mailing list:
https://groups.google.com/forum/#!topic/generic-abi/MPr8TVtnVn4

An object file manipulation tool must either write out a symbol
table with the same number of entries as the original symbol table
and in the same order, or if this is impossible, refuse to operate
on the object file if it has unrecognized sections that are linked
to the symtab section. However, existing tools (namely GNU strip,
GNU objcopy and ld.{bfd,gold,lld} -r) do not comply with this at
present: they change symbol table indexes and set sh_link to 0 on
the unrecognized symtab-linked sections.

We intend to use the latter as a (temporary) signal that a tool has
operated on a proposed new symtab-linked section and invalidated the
symbol table indexes. However, llvm-objcopy currently keeps sh_link
pointing to the new symtab section. This patch changes llvm-objcopy
to set sh_link to 0 to match the behaviour of the other tools.

[GlobalISel][Legalizer] LegalizerInfo verifier: check rules cover type indices

This commit adds a simple verifier that tracks type indices being
touched by legalization rules' builders.

Every target will now have an opportunity to call
LegalizerInfo::verify(...) at the end of its derived LegalizerInfo's
constructor and check there are no obvious mistakes like checking only
first type for an opcode that has more than one type index and therefore
implicitly declaring any type for the second (and higher) type index
legal.

The check is only ran in assert builds and should have very minor
performance impact in assert builds and none in release builds.

This commit does not add LegalizerInfo::verify(...) calls to
target-specific legalizers, look for separate commits for that.

This commit also doesn't make the verification errors fatal, only
produces an error message, look for a later commit that does.

Serge Pavlov [Wed, 30 May 2018 05:13:19 +0000 (05:13 +0000)]
Use uniform mechanism for OOM errors handling

This is a recommit of r333390, which was reverted in r333395, because it
caused cyclic dependency when building shared library `LLVMDemangle.so`.
In this commit `ItaniumDemangler.cpp` was not changed.

The original commit message is below.

In r325551 many calls of malloc/calloc/realloc were replaces with calls of
their safe counterparts defined in the namespace llvm. There functions
generate crash if memory cannot be allocated, such behavior facilitates
handling of out of memory errors on Windows.

If the result of *alloc function were checked for success, the function was
not replaced with the safe variant. In these cases the calling function made
the error handling, like:

    T *NewElts = static_cast<T*>(malloc(NewCapacity*sizeof(T)));
    if (NewElts == nullptr)
      report_bad_alloc_error("Allocation of SmallVector element failed.");

Actually knowledge about the function where OOM occurred is useless. Moreover
having a single entry point for OOM handling is convenient for investigation
of memory problems. This change removes custom OOM errors handling and
replaces them with calls to functions `llvm::safe_*alloc`.

Declarations of `safe_*alloc` are moved to a separate include file, to avoid
cyclic dependency in SmallVector.h

6 years ago[LoopInstSimplify] Re-implement the core logic of loop-instsimplify to
Chandler Carruth [Tue, 29 May 2018 20:15:38 +0000 (20:15 +0000)]
[LoopInstSimplify] Re-implement the core logic of loop-instsimplify to
be both simpler and substantially more efficient.

Rather than use a hand-rolled iteration technique that isn't quite the
same as RPO, use the pre-built RPO loop body traversal utility.

Once visiting the loop body in RPO, we can assert that we visit defs
before uses reliably. When this is the case, the only need to iterate is
when simplifying a def that is used by a PHI node along a back-edge.
With this patch, the first pass over the loop body is just a complete
simplification of every instruction across the loop body. When we
encounter a use of a simplified instruction that stems from a PHI node
in the loop body that has already been visited (due to some cyclic CFG,
potentially the loop itself, or a nested loop, or unstructured control
flow), we recall that specific PHI node for the second iteration.
Nothing else needs to be preserved from iteration to iteration.

On the second and later iterations, only instructions known to have
simplified inputs are considered, each time starting from a set of PHIs
that had simplified inputs along the backedges.

Dead instructions are collected along the way, but deleted in a batch at
the end of each iteration making the iterations themselves substantially
simpler. This uses a new batch API for recursively deleting dead
instructions.

This alsa changes the routine to visit subloops. Because simplification
is fundamentally transitive, we may need to visit the entire loop body,
including subloops, to handle knock-on simplification.

I've added a basic test file that helps demonstrate that all of these
changes work. It includes both straight-forward loops with
simplifications as well as interesting PHI-structures, CFG-structures,
and a nested loop case.

6 years ago[RISCV] Add peepholes for Global Address lowering patterns
Sameer AbuAsal [Tue, 29 May 2018 19:34:54 +0000 (19:34 +0000)]
[RISCV] Add peepholes for Global Address lowering patterns

Summary:
  Base and offset are always separated when a GlobalAddress node is lowered
  (rL332641) as an optimization to reduce instruction count. However, this
  optimization is not profitable if the Global Address ends up being used in only
  instruction.

  This patch adds peephole optimizations that merge an offset of
  an address calculation into the LUI %%hi and ADD %lo of the lowering sequence.

  The peephole handles three patterns:

 1) ADDI (ADDI (LUI %hi(global)) %lo(global)), offset
     --->
      ADDI (LUI %hi(global + offset)) %lo(global + offset).

   This generates:
   lui a0, hi (global + offset)
   add a0, a0, lo (global + offset)

   Instead of

   lui a0, hi (global)
   addi a0, hi (global)
   addi a0, offset

   This pattern is for cases when the offset is small enough to fit in the
   immediate filed of ADDI (less than 12 bits).

 2) ADD ((ADDI (LUI %hi(global)) %lo(global)), (LUI hi_offset))
     --->
      offset = hi_offset << 12
      ADDI (LUI %hi(global + offset)) %lo(global + offset)

   Which generates the ASM:

   lui  a0, hi(global + offset)
   addi a0, lo(global + offset)

   Instead of:

   lui  a0, hi(global)
   addi a0, lo(global)
   lui a1, (offset)
   add a0, a0, a1

   This pattern is for cases when the offset doesn't fit in an immediate field
   of ADDI but the lower 12 bits are all zeros.

 3) ADD ((ADDI (LUI %hi(global)) %lo(global)), (ADDI lo_offset, (LUI hi_offset)))
     --->
        offset = global + offhi20<<12 + offlo12
        ADDI (LUI %hi(global + offset)) %lo(global + offset)

   Which generates the ASM:

   lui  a1, %hi(global + offset)
   addi a1, %lo(global + offset)

   Instead of:

   lui  a0, hi(global)
   addi a0, lo(global)
   lui a1, (offhi20)
   addi a1, (offlo12)
   add a0, a0, a1

   This pattern is for cases when the offset doesn't fit in an immediate field
   of ADDI and both the lower 1 bits and high 20 bits are non zero.

[AArch64][SVE] Asm: Support for ADD (immediate) instructions.

This patch adds addsub_imm8_opt_lsl_(i8|i16|i32|i64) operands
that are unsigned values in the range 0 to 255. For element widths of
16 bits or higher it may also be a signed multiple of 256 in the
range 0 to 65280.

Note: This also does some refactoring to reuse convenience function
getShiftedVal<shift>(), and now allows AArch64 scalar 'ADD #-4096' to be
accepted to be mapped to SUB #4096.
