Also, add -h option to print usage information.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@3729 91177308-0d34-0410-b5e6-96231b3b80d8

Fixed problem with printing struct definitions in the correct order.
This allows for the Regression/Transforms/ScalarReplacement/scalarize.c to run correctly.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@3721 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@3719 91177308-0d34-0410-b5e6-96231b3b80d8

Moving to lib/CodeGen/RegAlloc.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@3718 91177308-0d34-0410-b5e6-96231b3b80d8

Function.h is unnecessary when Module.h is included.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@3716 91177308-0d34-0410-b5e6-96231b3b80d8

On the quest of eliminating unnecessary includes.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@3715 91177308-0d34-0410-b5e6-96231b3b80d8

Again, including Module makes Function unnecessary.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@3714 91177308-0d34-0410-b5e6-96231b3b80d8

Following Chris's advice, I'm pruning some unnecessary .h includes that I'm
noticing. Since Module includes Function, and eventually, BasicBlock and
GlobalVariable, the last three are unnecessary to be included directly.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@3713 91177308-0d34-0410-b5e6-96231b3b80d8

Factor platform specific makefile directives out into their own makefile
fragments.  This is gross, but having tons of confusing conditionals all
throughout the build system seems worst.

Credits got to Casey Carter for the idea.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@3705 91177308-0d34-0410-b5e6-96231b3b80d8

Add better linux support by using the right macro.  This still should be
autoconfiscated, but for now this is sufficient.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@3701 91177308-0d34-0410-b5e6-96231b3b80d8

Submitted by Casey Carter:

ISSUE: Linux doesn't have any steenking SIGEMT signal, as referred to in
lib/Support/Signals.cpp.

ACTION: Wrap the use with a #ifdef SIGEMT / #endif.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@3700 91177308-0d34-0410-b5e6-96231b3b80d8

Another portability fix provided via Casey Carter:

ISSUE: getTimeRecord in lib/VMCore/Pass.cpp uses timeval and
gettimeofday() without including sys/time.h.

ACTION: Include sys/time.h.

Add a new BasicBlockPass::doInitialization/Finalization(Function &) pair of
methods that may be useful for BasicBlockPasses.

Make sure to print a message when linking a tool

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@3687 91177308-0d34-0410-b5e6-96231b3b80d8

Compiling with "gmake" should produce less output. The compilation/linking
flags are always the same anyway, who wants to see so much text on the
screen? Compiling with "gmake VERBOSE=1" should produce all the output
you're used to.

Basically it checks for VERBOSE being defined, and if it is, sets VERB
appropriately. VERB is then prepended in a bunch of key places such that
when VERB is "@", the command is not echoed, when VERB is not set to
anything, it's as before.

One thing I could not get rid of is "gmake[1]: Entering directory <blah>",
but running "gmake -s" suppresses it all, and shows just the interesting
stuff.

Now output (when running "gmake -s" will look something like):

Recently changed getelementptr to use 'long' indexes for sequential types
instead of uints.  This adds a translation scheme to be backwards compatible
with old .ll files.
