Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting
fall out by removing unused variables. Remaining warnings have to do with
unused functions (I didn't want to delete code without review) and unused

issues when they see them. All changes pass DejaGnu tests and Olden.

Adjust usage of the ExecuteAndWait function to use the last argument which
is the ErrMsg string. This is necessitated because this function no longer
throws exceptions on error.

Make sys::Program::ExecuteAndWait not throw exceptions and update any
affected code. It now return -9999 to signal that the program couldn't be

Rid the Assembly Parser of exceptions. This is a really gross hack but it
will do until the Assembly Parser is re-written as a recursive descent.
The basic premise is that wherever the old "ThrowException" function was
called (new name: GenerateError) we set a flag (TriggerError). Every
production checks that flag and calls YYERROR if it is set. Additionally,
each call to ThrowException in the grammar is replaced with GEN_ERROR
which calls GenerateError and then YYERROR immediately. This prevents
the remaining production from continuing after an error condition.

This is faster because SplitFunctionsOutOfModule no longer calls Clone Module and then removes the functions it doesnt want from the module returned. Instead it creates a module and copies over the specified functions, making changes to the new and old module where neccessary. This reduces the memory demand.

Generally, remove use of fork/exec from bugpoint in favor of the portable
sys::Program::ExecuteAndWait method. This change requires two new options
to bugpoint to tell it that it is running in "child" mode. In this mode,
it reads its input and runs the passes. The result code signals to the
parent instance of bugpoint what happened (success, fail, crash).
This change should make bugpoint usable on Win32 systems.

SparcV9 JIT.
2. Make LLVMTransformUtils a relinked object file and always link it before

pointer marking the end of the list, the zero *must* be cast to the pointer
type. An un-cast zero is a 32-bit int, and at least on x86_64, gcc will
not extend the zero to 64 bits, thus allowing the upper 32 bits to be
random junk.
The new END_WITH_NULL macro may be used to annotate a such a function
so that GCC (version 4 or newer) will detect the use of un-casted zero
at compile time.

Instead of emitting a JIT stub that looks like this:
internal void %l1_main_entry_2E_ce_wrapper(int) {
header:
%resolver = call sbyte* %getPointerToNamedFunction( sbyte* getelementptr ([20 x sbyte]* %l1_main_entry_2E_ce_name, int 0, int 0) ) ; <sbyte*> [#uses=1]
%resolverCast = cast sbyte* %resolver to void (int)* ; <void (int)*> [#uses=1]
call void %resolverCast( int %0 )
ret void
}
Emit one that looks like this:
internal void %l1_main_entry_2E_ce_wrapper(int) {
Entry:
%fpcache = load void (int)** %l1_main_entry_2E_ce.fpcache ; <void (int)*> [#uses=2]
%isNull = seteq void (int)* %fpcache, null ; <bool> [#uses=1]
br bool %isNull, label %lookupfp, label %usecache
usecache: ; preds = %lookupfp, %Entry
%fp = phi void (int)* [ %resolverCast, %lookupfp ], [ %fpcache, %Entry ] ; <void (int)*> [#uses=1]
call void %fp( int %0 )
ret void
lookupfp: ; preds = %Entry
%resolver = call sbyte* %getPointerToNamedFunction( sbyte* getelementptr ([20 x sbyte]* %l1_main_entry_2E_ce_name, int 0, int 0) ) ; <sbyte*> [#uses=1]
%resolverCast = cast sbyte* %resolver to void (int)* ; <void (int)*> [#uses=2]
store void (int)* %resolverCast, void (int)** %l1_main_entry_2E_ce.fpcache
br label %usecache
}
This makes the JIT debugger *MUCH* faster on large programs, as
getPointerToNamedFunction takes time linear with the size of the program, and
before we would call it every time a function in the text module was called from
the safe module (ouch!).

This chagne just renames some sys::Path methods to ensure they are not
misused. The Path documentation now divides methods into two dimensions:
Path/Disk and accessor/mutator. Path accessors and mutators only operate
on the Path object itself without making any disk accesses. Disk accessors
and mutators will also access or modify the file system. Because of the
potentially destructive nature of disk mutators, it was decided that all
such methods should end in the work "Disk" to ensure the user recognizes
that the change will occur on the file system. This patch makes that
change. The method name changes are:
makeReadable -> makeReadableOnDisk
makeWriteable -> makeWriteableOnDisk
makeExecutable -> makeExecutableOnDisk
setStatusInfo -> setStatusInfoOnDisk
createDirectory -> createDirectoryOnDisk
createFile -> createFileOnDisk
createTemporaryFile -> createTemporaryFileOnDisk
destroy -> eraseFromDisk
rename -> renamePathOnDisk
These changes pass the Linux Deja Gnu tests.

Get rid of the difference between file paths and directory paths. The Path
class now simply stores a path that can refer to either a file or a
directory. This required various changes in the implementation and interface
of the class with the corresponding impact to its users. Doxygen comments were
also updated to reflect these changes. Interface changes are:
appendDirectory -> appendComponent
appendFile -> appendComponent
elideDirectory -> eraseComponent
elideFile -> eraseComponent
elideSuffix -> eraseSuffix
renameFile -> rename
setDirectory -> set
setFile -> set

1. Get rid of TOOLLINKOPTS as it is a hold over from llvm-test and only

two things: the FIXME in ExtractBlocks needs to be implemented, and the basic block
extractor itself needs to have enough bugs fixed for this to be more or less
useful.
Until the time that this is generally useful, it is hidden behind the new bugpoint

Also of note, this patch adds a -extract-bbs option to bugpoint which can be used

by creating an internal wrapper function with same signature as the external

The wrapper then calls the external function using the same JIT function
resolution API that has been used before for rewriting instructions, since the
wrapper has an explicit call instruction which we can rewrite.

1. Each time the loop extractor extracted a loop, we would leak a module.
2. When we extracted a loop, we didn't add the new function to the list of
miscompiled functions. Thus if the bug was in a loop nest and we
extracted it, we could actually *LOSE THE BUG*, which is very bad.
With these patches, bugpoint has successfully found a bug for me in a function
with several nested loops, and cut it down to just one of them. :) :)
