implementation, eliminating a dupe.

The later doesn't depend on any crazy LLVM IR stuff, and this
pulls the concatenation of prefix with GV name (the root problem behind
PR4584) out one level.

llvm-svn: 76778

a new getSectionForMergableConstant hook.  This removes one dependence
of TAI on Type, and provides the hook with enough info to make the 
right decision based on whether the global has relocations etc.

llvm-svn: 76705

Constant::getRelocationInfo(), which has a much simpler
to use API.  It still should not be part of libvmcore, but
is better than it was.  Also teach it to be smart about 
hidden visibility.

virtual.  Just inline it into its two current call sites in preparation
for simplifying the code.

llvm-svn: 76587

Re-apply 75490, 75806 and 76177 with fixes and tests.  Efficiency comes
next.

llvm-svn: 76486

Revert 76177 for now. It's messing up ARM asm printing. Also this significant debate about its efficiency.

llvm-svn: 76279

starting in getCurrentFunctionEHName.  Among other problems,
we would try to privative a "foo.eh" label, but end up emitting
the label as _Lfoo.eh instead of L_foo.eh on darwin.  This is really
bad, and the linker has always tolerated these labels existing.
For now, just emit them as _foo.eh.

This patch also fixes problems with ".eh" labels on unnamed
functions and eliminates two strangely defined TargetAsmInfo
hooks.

llvm-svn: 76231

Add logic to align instruction operands to columns for pretty-printing.
No target uses this currently.  This patch only adds the mechanism so
that local installations can choose to enable this.

llvm-svn: 76177

(llvm-gcc) has gone.

llvm-svn: 75781

This adds location info for all llvm_unreachable calls (which is a macro now) in
!NDEBUG builds.
In NDEBUG builds location info and the message is off (it only prints
"UREACHABLE executed").

llvm-svn: 75640

llvm-svn: 75508

Add infrastructure to allow post instruction printing action triggers.
We'll eventually use this to print comments in asm files and do other
fun things.

This adds interfaces to the AsmPrinter and changes TableGen to invoke
the postInstructionAction when appropriate.  It also add parameters to
TargetAsmInfo to control comment layout.

llvm-svn: 75490

Begin the painful process of tearing apart the rat'ss nest that is Constants.cpp and ConstantFold.cpp.
This involves temporarily hard wiring some parts to use the global context.  This isn't ideal, but it's
the only way I could figure out to make this process vaguely incremental.

llvm-svn: 75445

Make llvm_unreachable take an optional string, thus moving the cerr<< out of
line.
LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for
NDEBUG builds.

llvm-svn: 75379

into DarwinTargetAsmInfo.cpp.  The remaining differences should
be evaluated.  It seems strange that x86/arm has .zerofill but ppc
doesn't, etc.

Reapply 68847.
Now debug_inlined section is covered by TAI->doesDwarfUsesInlineInfoSection(), which is false by default.

llvm-svn: 68964

from the assembler:

Error: unknown pseudo-op: `.debug_inlined'
llvm-svn: 68863

Keep track of inlined functions and their locations. This information is collected when nested llvm.dbg.func.start intrinsics are seen. (Right now, inliner removes nested llvm.dbg.func.start intrinisics during inlining.) 

Create debug_inlined dwarf section using these information. This info is used by gdb, at least on Darwin, to enable better experience debugging inlined functions. See DwarfWriter.cpp for more information on structure of debug_inlined section.

llvm-svn: 68847

Do not propagate ELF-specific stuff (data.rel) into other targets. This simplifies code and also ensures correctness.
