for the Sparc backend: breaking up constant expressions. Thus, we cannot have it
guarded by a conditional, it should never be disabled.
Also, it's now available for the JIT since it is a FunctionPass.

since it is *necessary* for correct code generation. Only optional
transformations belong in the PreOpts pass (which needs to be renamed
from PreSelection to PreOpts).

Move LowerAllocations, PrintFunction, and SymbolStripping passes, and
the corresponding -disable-strip and -d options, over here to the SPARC
target-specific bits of llc. Rename -d to -dump-asm.
tools/llc/Makefile:
Reindent. Add x86 library so that llc compiles again.
tools/llc/llc.cpp:
Remove support for running arbitrary optimization passes. Use opt instead.
Remove LowerAllocations, PrintFunction, and SymbolStripping passes, as noted
above.
Allow user to select a backend (x86 or SPARC); default to guessing from
the endianness/pointer size of the input bytecode file.
Fix typos.
Delete empty .s file and exit with error status if target does not support
static compilation.

* Removed instruction scheduling as it is too slow to run in a JIT environment
* Removed other passes because they aren't necessary and can slow JIT down

Update file comment to contain a bunch of the overview mapping-info
documentation previously buried within the file.
Remove some unnecessary include/using stmts.
Rename pass to MappingInfoCollector.
Rewrite a lot of it so it doesn't use global instance variables and so
it outputs into MappingInfo objects and then dumps those out, instead of going
straight to an assembly file.
Change name of factory to getMappingInfoCollector.
Fold prologue & epilogue writers into MappingInfo methods.
lib/Target/Sparc/FInfo.cpp:
Correct file comment to reflect above change
lib/Target/Sparc/Sparc.cpp:
Change name of factory to getMappingInfoCollector.
llvm-svn: 6617
a default value is set in the header file.
* Fixed some code layout to make it more consistent with the rest of codebase
* Added addPassesToJITCompile() with relevant passes
llvm-svn: 6369
TargetMachine.cpp, since it is entirely machine-independent.
Also, add options to disable optional back-end passes (preselection and
instr. scheduling).
