Option parsing: properly handle flag aliases for joined options (PR23394)

Clang would previously assert when trying to use --extra-warnings, which is
a flag alias for -W, which is a joined option.

8 years ago[SystemZ] Reclassify f32 subregs of f64 registers
Ulrich Weigand [Mon, 4 May 2015 17:41:22 +0000 (17:41 +0000)]
[SystemZ] Reclassify f32 subregs of f64 registers

At the moment, all subregs defined by the SystemZ target can be modified
independently of the wider register.  E.g. writing to a GR32 does not
change the upper 32 bits of the GR64.  Writing to an FP32 does not change
the lower 32 bits of the FP64.

Hoewver, the upcoming support for the vector extension redefines FP64 as
one half of a V128.  Floating-point operations leave the other half of
a V128 in an unpredictable state, so it's no longer the case that writing
to an FP32 leaves the bits of the underlying register (the V128) alone.
I'd prefer to have separate subreg_ names for this situation, so that
it's obvious at a glance whether we're talking about a subreg that leaves
the other parts of the register alone.

No behavioral change intended.

ScheduleDAGInstrs should toggle kill flags on bundled instrs.

ScheduleDAGInstrs wasn't setting or clearing the kill flags on instructions inside bundles.  This led to code such as this

%R3<def> = t2ANDrr %R0

  t2IT 1, 24, %ITSTATE<imp-def>

BUNDLE %ITSTATE<imp-def,dead>, %R0<imp-use>

  R6<def,tied6> = t2ORRrr %R0<kill>, ...
%R3<def> = t2ANDrr %R0<kill>

where the kill flag was removed from the BUNDLE instruction, but not the t2ORRrr inside it.  The verifier then thought that
R0 was undefined when read by the AND.

This change make the toggleKillFlags method also check for bundles and toggle flags on bundled instructions.
Setting the kill flag is special cased as we only want to set the kill flag on the last instruction in the bundle.

MachO and COFF already do not require this (currently we have temporary hacks
to prevent ownership from being released, but those are brittle and should be
removed soon).

The placeholder mechanism allowed the relocation resolver to look at original
object file to obtain more information that are required to apply the
relocations. This is usually necessary in two cases:

- For relocations targetting sub-word memory locations, there may be pieces
  of the instruction at the target address which we should not override.
- Some relocations on some platforms allow an extra addend to be encoded in
  their immediate fields.

The problem is that in the second case the information cannot be recovered
after the relocations have been applied once because they will have been
overridden. In the first case we also need to be careful to not use any bits
that aren't fixed and may have been overriden by applying a first relocation.

In the past both have been fixed by just looking at original object file. This
patch attempts to recover the information from the first by looking at the
relocated object file, while the extra addend in the second case is read
upon relocation processing and addend to the regular addend.

I have tested this on X86. Other platforms represent my best understanding
of how those relocations should work, but I may have missed something because
I do not have access to those platforms.
We will keep the ugly workarounds in place for a couple of days, so this commit
can be reverted if it breaks the bots.

Fix for PR23103. Correctly propagate the 'IsUndef' flag to the register operands of a commuted instruction.

Revision 220239 exposed a latent bug in method
'TargetInstrInfo::commuteInstruction'. When commuting the operands of a machine
instruction, method 'commuteInstruction' didn't correctly propagate the
'IsUndef' flag to the register operands of the new (commuted) instruction.

Before this patch, the following instruction:
  %vreg4<def> = VADDSDrr  %vreg14, %vreg5<undef>; FR64:%vreg4,%vreg14,%vreg5

was wrongly converted by method 'commuteInstruction' into:
  %vreg4<def> = VADDSDrr  %vreg5, %vreg14<undef>; FR64:%vreg4,%vreg5,%vreg14

The correct instruction should have been:
  %vreg4<def> = VADDSDrr  %vreg5<undef>, %vreg14; FR64:%vreg4,%vreg5,%vreg14

This patch fixes the problem in method 'TargetInstrInfo::commuteInstruction'.
When swapping the operands of a machine instruction, we now make sure that
'IsUndef' flags are correctly set.
Added test case 'pr23103.ll'.

DigitsT. This was preventing instantiations of ScaledNumber with
anything other than uint64_t types.

In implementing the tests, I ran into another issue. Operators >>= and
<<= did not have variants for accepting other ScaledNumber as the shift
argument. This is expected by the SCALED_NUMBER_BOP.

It makes no sense to allow shifting a ScaledNumber by another
ScaledNumber, so the patch includes two new templates for shifting
ScaledNumbers.
