Chris Lattner 80c345927e delete a forwarding function.

Chris Lattner 5418dd5fda move elf section uniquing to MCContext. Along the way 
merge XCore's section into MCSectionELF

llvm-svn: 100812
 2010-04-08 21:26:26 +00:00
Chris Lattner 433d40695b remove the TargetLoweringObjectFileMachO::getMachoSection 
api and update clients to use MCContext instead.

llvm-svn: 100808
 2010-04-08 20:40:11 +00:00
Chris Lattner 2073112fc0 move macho section uniquing from MCParser and TLOF to MCContext where 
the compiler and asmparser now unique to the same sections.  This fixes
rdar://7835021.

llvm-svn: 100807
 2010-04-08 20:30:37 +00:00
Chris Lattner 2104b8d36e rename llvm::llvm_report_error -> llvm::report_fatal_error 
llvm-svn: 100709
 2010-04-07 22:58:41 +00:00
Chris Lattner 9897043928 Rip out the 'is temporary' nonsense from the MCContext interface to 
create symbols.  It is extremely error prone and a source of a lot
of the remaining integrated assembler bugs on x86-64.

This fixes rdar://7807601.

Bill Wendling bbcaa40227 Now that the default for Darwin platforms is to place the LSDA into the TEXT 
section, remove the target-specific code that performs this.

Chris Lattner 2ea586b8f5 use Mang->getSymbol() more. 
llvm-svn: 98577
 2010-03-15 20:37:38 +00:00
Chris Lattner 632eb65cd2 fix MCSectionELF to not leak memory, just like I did for MCSymbol. 
MCSectionMachO is already fine (yay for fixed size arrays?),
MCSectionCOFF still leaks.

llvm-svn: 98537
 2010-03-15 06:23:52 +00:00
Chris Lattner 03627cb12c fix a fixme in TargetLoweringObjectFile::getExprForDwarfReference 
where we used ot create an MCSymbol for ".".  Now emit an assembler
temporary label and reference it instead of "." textually.

 2010-03-11 21:55:20 +00:00
Chris Lattner 2562356992 rename getSymbolForDwarf* to getExprForDwarf* since it returns 
an MCExpr and not an MCSymbol.  Change it to take an MCStreamer,
which is currently unused.

No functionality change.

Bill Wendling a810bdfcca Add a bit along with the MCSymbols stored in the MachineModuleInfo maps that 
indicates that an MCSymbol is external or not. (It's true if it's external.)
This will be used to specify the correct information to add to non-lazy
pointers. That will be explained further when this bit is used.

Chris Lattner 71c30c164f move three lowering hooks from MAI to TLOF and make one of them 
semantic instead of syntactic.  This completes MCization of
darwin/x86[-64]!

llvm-svn: 98145
 2010-03-10 07:20:42 +00:00
Chris Lattner ac2361a9b0 set the temporary bit on MCSymbols correctly.

Charles Davis 8545afe0b0 Don't emit global symbols into the (__TEXT,__ustring) section on Darwin. This 
is a workaround for <rdar://problem/7672401/> (which I filed).

This let's us build Wine on Darwin, and it gets the Qt build there a little bit
further (so Doug says).

Bill Wendling ce153affa3 Okay. One last attempt: 
Place the LSDA into the TEXT section on Mach-O. This saves space.

Anton Korobeynikov 31a9212b0b It turned out that we failed to emit proper symbol stubs on non-x86/darwin for ages (we emitted a reference to a stub, but no stub was emitted). The code inside x86-32/macho target objfile lowering should actually be the generic one - move it there. 
This (I really, really hope) should fix EH issues on ppc/darwin
and arm/darwin.

Bob Wilson 336c0a1c87 Revert Anton's most recent EH patch (r96637), since it breaks a lot of 
ARM and Thumb tests.

 2010-02-19 17:10:59 +00:00
Anton Korobeynikov 9baeb02000 Use the same encoding for EH stuff uniformly on all MachO targets. 
This hopefulyl should unbreak EH on PPC/Darwin.

Anton Korobeynikov ab663a0bfe Move TLOF implementations to libCodegen to resolve layering violation.
