I think local symbols in X86 GAS have to start with .L, not just

2. Otherwise, set OBJ_ROOT to .

in TargetInstrInfo::ConvertConstantToIntType.

Bug fix: after reallocating the hash table, we have to re-insert each value
instead of copying table entries!

Rename 'dump-asm' to 'dump-input' and really print it just before code-gen.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7394 91177308-0d34-0410-b5e6-96231b3b80d8

Bug fix: don't unnecessarily pretty-print control-characters, some of
which were wrong (particularly, '\a' for '\007').

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7393 91177308-0d34-0410-b5e6-96231b3b80d8

Add ConvertConstantToIntType() to unify all constant handling
that depends on machine register size.
Moved insertCallerSavingCode() to PhyRegAlloc and
moved isRegVolatile and modifiedByCall to TargetRegInfo: they are all
machine independent.  Remove several dead functions.

Add code to support stack spill/temp offsets that don't fit in the
immed. field.  Moved insertCallerSavingCode() to PhyRegAlloc: it is
now machine independent.  Remove all uses of PhyRegAlloc.

All constant-evaluation code now unified into
TargetInstrInfo::ConvertConstantToIntType().

1. Bug fix:  Don't use branch operand reg. as temp. reg. when
   spilling values used by an instruction in the delay slot of the branch
   (which will eventually be moved before the branch).
2. Bug fix:  Delete the delay slot instr, not the branch instr, when
   moving delay slot instr. out!!!!
3. Move code to insert caller-saves moved here from SparcRegInfo:
   it is now machine-independent.

Don't require a BB to look-up live variables, unless they may need to
be recomputed.

Add const version of getLiveRangeForValue().

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7386 91177308-0d34-0410-b5e6-96231b3b80d8

Code to insert caller-saves moved here from SparcRegInfo: it is now
machine-independent.
Fix problem with using branch operand reg. as temp. reg. when
spilling values used by an instruction in the delay slot of the branch
(which will eventually be moved before the branch).

Enable JIT when the platform supports it.
Select /localhome/$USER when it exists.
Fix the checks for bidirectional and forward iterators so that they work with
version of GCC prior to 3.x.

* Correctly emit a far call if the target address does not fit into 30 bits
  instead of assert()ing
* Fixed a nasty bug where '07' was used instead of register 'o7'

* Stop hard-coding a value for beginning of emitted code on Sparc since we can
  now handle far calls (i.e., beyond the 30-bit limit in call instructions).
* As a side-effect, this allows us to unify and clean up the mmap() call and
  code around it.

* Disambiguate symbols before we start splitting module by functions
* Moved DisambiguateGlobalSymbols() out of the ReduceMisCodegenFunctions class
* Added an assert to have a cleaner exit if `main' is not found in the module
