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

# These *MUST* match the output of gas compiled with the same triple and
# corresponding options (-mcpu=mips32 -> -mips32 for example).
Remove some really nasty uses of hasRawTextSupport. When MC was first added, targets could use hasRawTextSupport to keep features working before they were added to the MC interface. The design goal of MC is to provide an uniform api for printing assembly and object files. Short of relaxations and other corner cases, a object file is just another representation of the assembly. It was never the intention that targets would keep doing things like if (hasRawTextSupport()) Set flags in one way. else Set flags in another way. When they do that they create two code paths and the object file is no longer just another representation of the assembly. This also then requires testing with llc -filetype=obj, which is extremelly brittle. This patch removes some of these hacks by replacing them with smaller ones. The ARM flag setting is trivial, so I just moved it to the constructor. For Mips, the patch adds two temporary hack directives that allow the assembly to represent the same things as the object file was already able to. The hope is that the mips developers will replace the hack directives with the same ones that gas uses and drop the -print-hack-directives flag. I will also try to implement a target streamer interface, so that we can move this out of the common code. In summary, for any new work, two rules of the thumb are * Don't use "llc -filetype=obj" in tests. * Don't add calls to hasRawTextSupport. llvm-svn: 192035

Clang has been updated to disable both possible default ABI's before enabling the ABI it intends to use. [*] N64 being the default for MIPS64 is not actually correct.

[mips] Add initial (experimental) MIPS-IV support. Summary: Adds the 'mips4' processor and a simple test of the ELF e_flags. Patch by David Chisnall His work was sponsored by: DARPA, AFRL I made one small change to the testcase so that it uses mips64-unknown-linux instead of mips4-unknown-linux. This patch indirectly adds FeatureCondMov to FeatureMips64. This is ok because it's supposed to be there anyway and it turns out that FeatureCondMov is not a predicate of any instructions at the moment (this is a bug that hasn't been noticed because there are no targets without the conditional move instructions yet).

[mips] Make it impossible to have UnknownABI in CodeGen and Integrated Assembler. Summary: This removes the need to coerce UnknownABI to the default ABI (O32 for MIPS32, N64 for MIPS64 [*]) in both MipsSubtarget and MipsAsmParser. Clang has been updated to disable both possible default ABI's before enabling the ABI it intends to use. [*] N64 being the default for MIPS64 is not actually correct. However N32 is not fully implemented/tested yet.

[mips] Fix ELF header flags. As opposed to GCC/GAS the default ABI for Mips64 is n64. Compatibility bit should be set if o32 ABI is used when targeting Mips64. llvm-svn: 200332

[mips] Add initial support for NaN2008 in the back-end. This is so that EF_MIPS_NAN2008 is set if we are using IEEE 754-2008 NaN encoding (-mnan=2008). This patch also adds support for parsing '.nan legacy' and '.nan 2008' assembly directives. The handling of these directives should match GAS' behaviour i.e., the last directive in use sets the ELF header bit (EF_MIPS_NAN2008).

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
