Don't pass a Reloc::Model to MC. MC only needs to know if the output is PIC or not. It never has to decide about creating GOTs and PLTs for example. The only thing that MC itself uses this information for is expanding "macros" in sparc and mips. The rest I am pretty sure could be moved to CodeGen. This is a cleanup and isolates the code from future changes to Reloc::Model. llvm-svn: 269909

[mips][ias] Fix N32 and N64 .cprestore directive when inside .set noat region. Summary: r268058 unintentionally made the retrieval of the current assembler temporary unconditional. This was fine for the existing tests but it broke the cases where the assembler temporary is not needed (N32/N64 or not PIC) and is unavailable due to a '.set noat' directive. This fixes FreeBSD's libc. Reviewers: emaste, sdardis, seanbruno Subscribers: dsanders, emaste, sdardis, llvm-commits Differential Revision: http://reviews.llvm.org/D20093 llvm-svn: 269179

[llvm-objdump] Support detection of feature bits from the object and implement this for Mips. Summary: The Mips implementation only covers the feature bits described by the ELF e_flags so far. Mips stores additional feature bits such as MSA in the .MIPS.abiflags section. Also fixed a small bug this revealed where microMIPS wouldn't add the EF_MIPS_MICROMIPS flag when using -filetype=obj.

[mips][ias] Fix O32 .cprestore directive when inside .set noat region and offset is in range. Summary: This expands on r269179 to fix an additional case that was not covered by our tests. The assembler temporary is not needed when the .cprestore offset fits inside a simm16 and it is not an error to use it inside a '.set noat' in this case.
