Chandler Carruth f3e8502cc1 Add 'llvm_unreachable' to passify GCC's understanding of the constraints
of several newly un-defaulted switches. This also helps optimizers
(including LLVM's) recognize that every case is covered, and we should
assume as much.

Nick Lewycky 50f02cb21b Move global variables in TargetMachine into new TargetOptions class. As an API
change, now you need a TargetOptions object to create a TargetMachine. Clang
patch to follow.

One small functionality change in PTX. PTX had commented out the machine
verifier parts in their copy of printAndVerify. That now calls the version in
LLVMTargetMachine. Users of PTX who need verification disabled should rely on
not passing the command-line flag to enable it.

Evan Cheng bbf3b0de8b Goodbye TargetAsmInfo. This eliminate last bit of CodeGen and Target in llvm-mc.
There is still a bit more refactoring left to do in Targets. But we are now very
close to fixing all the layering issues in MC.

supports compact unwind info instead of having a separate flag indicating this.

Bill Wendling d346304373 Add a __LD,__compact_unwind section.
If the linker supports it, this will hold the CIE and FDE information in a

Bill Wendling a48b1375df Remove a flag that would set the ".eh" symbol as .globl. MachO was the only one
who used this flag, and it now emits CFI and doesn't emit this anymore. All
other targets left this flag "false".

Rafael Espindola 750cb61553 GCC uses a different encoding of pointers in the FDE when using
-fno-dwarf2-cfi-asm. Implement the same behavior.

Rafael Espindola 08704349da Rename getPersonalityPICSymbol to getCFIPersonalitySymbol, document it, and
give it a bit more responsibility. Also implement it for MachO.

If hacked to use cfi, 32 bit MachO will produce

.cfi_personality 155, L___gxx_personality_v0$non_lazy_ptr

and 64 bit will produce

.cfi_presonality ___gxx_personality_v0

The general idea is that .cfi_personality gets passed the final symbol. It is
up to codegen to produce it if using indirect representation (like 32 bit
MachO), but it is up to MC to decide which relocations to create.

Rafael Espindola a01cdb0e37 Add 129518 back with a fix for when we are producing eh just because of debug info.

Chris Lattner a986aa33eb fix a significant difference between llvm and gcc on ELF systems:
GCC would put weak zero initialized mutable data in the .bss section,
we would put it into a crasy '.gnu.linkonce.b.test,"aw",@nobits' 
section.  Fixing this will allow simplifications next up.

Chris Lattner 5b585f8b1a introduce a section kind for common linkage. Use this to slightly
simplify and commonize some of the asmprinter logic for globals.

This also avoids printing the MCSection for .zerofill, which broke
the llvm-gcc build.

2010-01-19 02:48:26 +00:00
Chris Lattner 1d371882b6 Cleanup handling of .zerofill on darwin:
1. TargetLoweringObjectFileMachO should decide if something
   goes in zerofill instead of having every target do it.
2. TargetLoweringObjectFileMachO should assign said symbols to
   the right MCSection, the asmprinters should just emit to the
   right section.
3. Since all zerofill stuff goes through mcstreamer anymore,
   MAI can have a bool "haszerofill" instead of having the textual
   directive to emit.
