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!

llvm-svn: 52994
 2008-07-01 23:34:48 +00:00
Anton Korobeynikov 2e052a81fd Start refactoring of asmprinters: provide a TAI hook, which will select a 'section kind' for a global.

Dale Johannesen 355b74acc2 Add StringConstantPrefix to control what the 
assembler names of string constants look like.

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.

Anton Korobeynikov ae24cca0e4 Preparation step for some cleanup/generalization in EH information emission:

Dale Johannesen 7ecb3b79c7 Emit unused EH frames for weak definitions on Darwin, 
because assembler/linker can't cope with weak absolutes.
PR 1880.

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.

for Darwin PPC, but it's not fully working yet.

Dan Gohman a1d46c7d0a TargetAsmInfo::getAddressSize() was incorrect for x86-64 and 64-bit targets 
other than PPC64. Instead of fixing it, just remove it and fix all the
places that use it to use TargetData::getPointerSize() instead, as there
aren't very many. Most of the references were in DwarfWriter.cpp.

Dan Gohman 0cc9d1b93b Merge hasDotLoc and hasDotFile into hasDotLocAndDotFile since .loc and .file

Bill Wendling 74fb0f1a1c Add a bool to indicate if we should set the "indirect encoding" bit in the Dwarf 
information for EH.

Bill Wendling 2b8fc31df9 The personality function on Darwin needs a global stub. We then refer to 
that global stub instead of doing the ".set" thingy we were doing before.

Anton Korobeynikov b538f67b1a Fix couple of bugs connected with eh info: 
1. Correct output offsets on Linux
2. Fix "style" of personality function. It shouldn't be indirect.

Anton Korobeynikov 39f3cffbe3 Implement protected visibility. This partly implements PR1363. Linker
