This is possible if there is an undef use when
splitting the vreg during spilling.

Fixes bug 33620.

As discussed on llvm-dev I've implemented the first basic steps towards
llvm-objcopy/llvm-objtool (name pending).

This change adds the ability to copy (without modification) 64-bit
little endian ELF executables that have SHT_PROGBITS, SHT_NOBITS,
SHT_NULL and SHT_STRTAB sections.

We have the same relation between class properties and getter/setters
that we have for instance properties, so set the same symbol sub-kind.

Targets.cpp is getting unwieldy, and even minor changes cause the entire thing 
to cause recompilation for everyone. This patch bites the bullet and breaks 
it up into a number of files.

I tended to keep function definitions in the class declaration unless it 
caused additional includes to be necessary. In those cases, I pulled it 
over into the .cpp file. Content is copy/paste for the most part, 
besides includes/format/etc.

As discussed on [1], if the profile is compressed and llvm-profdata is not built with zlib support, the error message is not informative. Give a better error message if zlib is not available.

MIR SRADI uses instruction template XSForm_1rc which declares Defs = [CARRY]. But MIR SRADI_32 uses instruction template XSForm_1, and it doesn't declare such implicit definition. With patch D33720 it causes wrong code generation for perl.

This patch adds the implicit definition.

This change is part of the RegCall calling convention support for LLVM. 
Existing RegCall implementation was extended to include correct handling of 
Complex Long Double type. Complex long double types should be returned/passed 
in memory and not register stack. This patch implements this behavior.

This includes the hash table, the address map, and the thunk table and
section offset table. The last two are only used for incremental
linking, which LLD doesn't support, so they are less interesting. The
hash table is particularly important to get right, since this is the one
of the streams that debuggers use to translate addresses to symbols.

For example
  asm ("memw(%0++%1) = %2" : : "r"(addr),"a"(mod),"r"(val) : "memory")

Summary: Currently the ThinLTO minimized bitcode file only strip the debug info, but there is still a lot of information in the minimized bit code file that will be not used for thin linker. In this patch, most of the extra information is striped to reduce the minimized bitcode file. Now only ModuleVersion, ModuleInfo, ModuleGlobalValueSummary, ModuleHash, Symtab and Strtab are left. Now the minimized bitcode file size is reduced to 15%-30% of the debug info stripped bitcode file size.
