Peephole optimization in switch table lookup: reuse the guarding table comparison if possible.

This optimization tries to reuse the generated compare instruction, if there is a comparison against the default value after the switch.
Example:
    if (idx < tablesize)
       r = table[idx]; // table does not contain default_value
    else
       r = default_value;
    if (r != default_value)

    cond = idx < tablesize;
    if (cond)
       r = table[idx];
    else
       r = default_value;
    if (cond)

changes to existing relocations:

1. R_AARCH64_NONE is defined to be zero rather than 256

R_AARCH64_NONE has been defined to be zero for a long time elsewhere
e.g. binutils and glibc since the submission of the AArch64 port in
2012 so this is required for compatibility.

2. R_AARCH64_TLSDESC_ADR_PAGE renamed to R_AARCH64_TLSDESC_ADR_PAGE21

I don't think there is any way for relocation names to leak out of LLVM
so this should not break anything.

Tested with check-all with no regressions.

Lang Hames [Wed, 26 Nov 2014 06:53:26 +0000 (06:53 +0000)]
[MCJIT] Clean up RuntimeDyld's quirky object-ownership/modification scheme.

Previously, when loading an object file, RuntimeDyld (1) took ownership of the
ObjectFile instance (and associated MemoryBuffer), (2) potentially modified the
object in-place, and (3) returned an ObjectImage that managed ownership of the
now-modified object and provided some convenience methods. This scheme accreted
over several years as features were tacked on to RuntimeDyld, and was both
unintuitive and unsafe (See e.g. http://llvm.org/PR20722).

This patch fixes the issue by removing all ownership and in-place modification
of object files from RuntimeDyld. Existing behavior, including debugger
registration, is preserved.

Noteworthy changes include:

(1) ObjectFile instances are now passed to RuntimeDyld by const-ref.
(2) The ObjectImage and ObjectBuffer classes have been removed entirely, they
    existed to model ownership within RuntimeDyld, and so are no longer needed.
(3) RuntimeDyld::loadObject now returns an instance of a new class,
    RuntimeDyld::LoadedObjectInfo, which can be used to construct a modified
    object suitable for registration with the debugger, following the existing
    debugger registration scheme.
(4) The JITRegistrar class has been removed, and the GDBRegistrar class has been
    re-written as a JITEventListener.

This should fix http://llvm.org/PR20722 .
