Anton Korobeynikov 7c5f3c40ca Do not propagate ELF-specific stuff (data.rel) into other targets. This simplifies code and also ensures correctness.

Dan Gohman 31dd016f81 Recognize inline asm for bswap on x86-64 GLIBC. This allows it 
to be supported in the JIT.

Bill Wendling 03f2af79b8 Linux wants the FDE initial location and address range to be forced to 32-bit. 
Darwin doesn't. Make this optional for platforms.

 2008-12-29 22:12:11 +00:00
Bill Wendling d6bd7e9372 Darwin likes for the EH frame to be non-local.

 2008-12-24 08:05:17 +00:00
Bill Wendling 066b5f6724 GCC doesn't emit DW_EH_PE_sdata4 for the FDE encoding on Darwin. I'm not sure 
about other platforms.

Rafael Espindola 770b4b830a Fix bug 3202. 
The EH_frame and .eh symbols are now private, except for darwin9 and earlier.
The patch also fixes the definition of PrivateGlobalPrefix on pcc linux.

Rafael Espindola cda011b5ad Fix bug 3140. 
Print a single parameter .file directive if we have an ELF target.

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).
