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

"LinkerPrivatePrefix". It seems to have been used in only one place before I
started this "linker_private" business. I'm thinking that a rename is in
order...

 - This provides the AsmLexer interface to the target specific assembly parsers.

llvm-svn: 76460

Fix some sub-reg coalescing bugs where the coalescer wasn't updating the resulting interval's register class.

"private" symbols which the assember shouldn't strip, but which the linker may
remove after evaluation. This is mostly useful for Objective-C metadata.

This is plumbing, so we don't have a use of it yet. More to come, etc.

being more consistent with other backends, this makes the SPARC backend 
deal with functions with arguments with illegal types correctly, which 
fixes some tests in test/CodeGen/Generic.

copied from the SystemZ target.  I don't think this causes any 
significant changes to the output (I compared the assembly, and the 
results appeared to be essentially unchanged), although I don't actually 
have an Alpha to test on.

I would appreciate if anyone with the appropriate hardware could test 
this. I'm not sure if that includes anyone subscribed to llvm-commits, 
though.

 - What it doesn't have is the rest of its cmake files...

llvm-svn: 76352

 - We should canonicalize this and get rid of the cmake and llvm-config hacks to
   support both variants.

llvm-svn: 76350

 - Shouldn't really be necessary, but currently .inc files get included into
   some main target headers.

Use R_X86_64_32S to handle Jump Table Index relocation entries. Hide TAI usage inside getSection* functions

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

llvm-svn: 76279

Fix x86 inline ams 'q' constraint support. In 32-bit mode, it's just like 'Q', i.e. EAX, EDX, ECX, EBX. In 64-bit mode, it just means all the i64r registers. Yeah, that makes sense.

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.
