This reverts commit r200064 and r200051. r200064 depends on r200051. r200051 is broken: I tries to replace .mips_hack_elf_flags, which is a good thing, but what it replaces it with is even worse. The new emitMipsELFFlags it adds corresponds to no assembly directive, is not marked as a hack and is not even printed to the .s file. The patch also introduces more uses of hasRawTextSupport. The correct way to remove .mips_hack_elf_flags is to have the mips target streamer handle the default flags (and command line options). That way the same code path is used for asm and obj. The streamer interface should *really* correspond to what is printed in the .s file. llvm-svn: 200078

[mips] Don't derive the default ABI from the CPU in the backend. Summary: The backend has no reason to behave like a driver and should generally do as it's told (and error out if it can't) instead of trying to figure out what the API user meant. The default ABI is still derived from the arch component as a concession to backwards compatibility. API-users that previously passed an explicit CPU and a triple that was inconsistent with the CPU (e.g. mips-linux-gnu and mips64r2) may get a different ABI to what they got before. However, it's expected that there are no such users on the basis that CodeGen has been asserting that the triple is consistent with the selected ABI for several releases. API-users that were consistent or passed '' or 'generic' as the CPU will see no difference.

[mips] Recommit: "N64 static relocation model support" This patch makes one change to GOT handling and two changes to N64's relocation model handling. Furthermore, the jumptable encodings have been corrected for static N64. Big GOT handling is now done via a new SDNode MipsGotHi - this node is unconditionally lowered to an lui instruction. The first change to N64's relocation handling is the lifting of the restriction that N64 always uses PIC. Now it is possible to target static environments. The second change adds support for 64 bit symbols and enables them by default. Previously N64 had patterns for sym32 mode only. In this mode all symbols are assumed to have 32 bit addresses. sym32 mode support is selectable with attribute 'sym32'. A follow on patch for clang will add the necessary frontend parameter. This partially resolves PR/23485. Thanks to Brooks Davis for reporting the issue! This version corrects a "Conditional jump or move depends on uninitialised value(s)" error detected by valgrind present in the original commit.

Implement the missing bits corresponding to .mips_hack_elf_flags. These were: * noreorder handling on the target object streamer and asm parser. * setting the initial flag bits based on the enabled features. * setting the elf header flag for micromips It is *really* depressing I am the one doing this instead of someone at mips actually taking the time to understand the infrastructure. llvm-svn: 200138
