It was only implemented for ELF where it collected the Addend, so this
patch also renames it to getRelocationAddend.

This reverts commit r181471.

llvm-svn: 181496

A computable loop exit count does not imply the presence of an induction
variable. Scalar evolution can return a value for an infinite loop.

Fixes PR15926.

- the temporaries "-debug.ll" files generated by DebugIR pass are considered tests, even though they are not

for constructors and destructors since the original declaration given
by the AT_specification both won't and can't.

Patch by Yacine Belkadi, I've cleaned up the testcases.

llvm-svn: 181471

- simple one-function case
- function-calling case
- external function calling case
- exception throwing case
- vector case

Note: these tests are somewhat coupled to the current format of debug metadata.
llvm-svn: 181469

- requires existing debug information to be present
- fixes up file name and line number information in metadata
- emits a "<orig_filename>-debug.ll" succinct IR file (without !dbg metadata
  or debug intrinsics) that can be read by a debugger
- initialize pass in opt tool to enable the "-debug-ir" flag
- lit tests to follow

llvm-svn: 181467

- made all functions virtual so that subclasses can specialize them
- add printInstructionLine so that subclasses can choose whether or not to
  print the newline character (without having to implement printBasicBlock()
- added a second constructor to AssemblyWriter that does not require a
  SlotTracker, as required in order to keep the SlotTracker helper class outside
  AsmWriter.h and buried in the implementation.

llvm-svn: 181466

- previously formatted_raw_ostream tracked columns, now it tracks lines too
- used by (upcoming) DebugIR pass to know the line number to connect to each IR
  instruction

[PowerPC] Add ELF relocation tests

This patch extends test/MC/PowerPC/ppc64-fixups.s to not only check for
the correct fixup type in the --show-encoding output, but also runs the
generated object file through llvm-readobj -r and verifies that the
correct ELF relocation records were generated.

[PowerPC] Add some missing PPC64 relocs

All R_PPC_... relocs should also be present (using the same number)
under the corresponding R_PPC64_... name.   The latter were missing
for a couple of cases, which this patch adds.

This is not a big problem when emitting the reloc, because we can
just use the R_PPC_... define instead.  But it is a problem when
*dumping* relocations e.g. using llvm-readobj, because this will
expect only R_PPC64_... values when inspecting a ppc64 ELF file.

[PowerPC] Fix regression in generating @ha/@l relocs

The patch I committed as revision 167864 introduced a regression that
causes LLVM to no longer generate appropriate relocs for @ha/@l symbol
references (but fail an assertion instead).

This is fixed here by re-enabling support for the VK_PPC_GAS_HA16/
VK_PPC_GAS_LO16 variant kinds (and their Darwin variants) in
PPCELFObjectWriter.cpp.

Tested by running projects/test-suite in -m32 mode with the integrated
assembler forced on.  A standalone test case will be committed shortly
as well.

This fixes bug 15821 similarly to the powerpc64-linux fix for bug 14779.

The floating-point record forms on PPC don't set the condition register bits
based on a comparison with zero (like the integer record forms do), but rather
based on the exception status bits.

The reference encoding is correct, but written in the wrong byte order (these are Thumb tests, while the reference is in ARM byte order).

Fold (xor (and x, y), y) -> (and (not x), y)

This removes an opportunity for a constant to appear twice.

llvm-svn: 181395

This provides basic functionality for imported declarations. For
subprograms and types some amount of lazy construction is supported (so
the definition of a function can proceed the using declaration), but it
still doesn't handle declared-but-not-defined functions (since we don't
generally emit function declarations).

Variable support is really rudimentary at the moment - simply looking up
the existing definition with no support for out of order (declaration,
imported_module, then definition).

The two nested loops were confusing and also conservative in identifying
reduction variables. This patch replaces them by a worklist based approach.

A = 9
B = 3 * A - 2 * A + 1 as  B = 3 * A - (2 * A + 1)

DIBuilder::createImportedDeclaration isn't fully plumbed through (note,
lacking in AsmPrinter/DwarfDebug support) but this seemed like a
sufficiently useful division of code to make the subsequent patch(es)
easier to follow.
