Dan Gohman ac41d9f5d8 Refactor various TargetAsmInfo subclasses' TargetMachine members away 
adding a TargetMachine member to the base TargetAsmInfo class instead.

Dale Johannesen f080225490 Fix logic for not emitting no-dead-strip for some 
objects in llvm.used (thanks Anton).  Makes visible
the magic 'l' prefix for symbols on Darwin which are
to be passed through the assembler, then removed at
linktime (previously all references to this had been
hidden in the ObjC FE code, oh well).

Duncan Sands 04fb6bf468 Linux also does not require exception handling 
moves in order to get correct debug info.  Since
I can't imagine how any target could possibly
be any different, I've just stripped out the
option: now all the world's like Darwin!

llvm-svn: 53134
 2008-07-04 09:55:48 +00:00
Bill Wendling b7bd02be57 Darwin doesn't need exception handling information for the "move" info when 
debug information is being output, because it's leet!

Duncan Sands e2b0bf43a7 Output correct exception handling and frame info 
on x86-64 linux.  This causes no regressions on
32 bit linux and 32 bit ppc.  More tests pass
on 64 bit ppc with no regressions.  I didn't
turn on eh on 64 bit linux because the intrinsics
needed to compile the eh runtime aren't done
yet.  But if you turn it on and link with the
mainline runtime then eh seems to work fine
on x86-64 linux with this patch.  Thanks to
Dale for testing.  The main point of the patch
is that if you output that some object is
encoded using 4 bytes you had better not output
8 bytes for it: the patch makes everything
consistent.

Dan Gohman bcde172222 Add AsmPrinter support for emitting a directive to declare that 
the code being generated does not require an executable stack.

Also, add target-specific code to make use of this on Linux
on x86.

Gordon Henriksen 84c7325ca1 Setting GlobalDirective in TargetAsmInfo by default rather than 
providing a misleading facility. It's used once in the MIPS backend
and hardcoded as "\t.globl\t" everywhere else.
