[mips] Fix ELF e_flags related to -mabicalls and -mplt. Summary: These options are not implemented yet but we act as if they are always given. The integrated assembler is driven by the clang driver so the e_flag test cases should match the e_flags emitted by GCC+GAS rather than GAS by itself.

# 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192035 91177308-0d34-0410-b5e6-96231b3b80d8

[mips] Correct ELF e_flags for the N32 ABI when using a mips-* triple rather than a mips64-* triple Summary: Generally speaking, mips-* vs mips64-* should not be used to make decisions about the content or format of the ELF. This should be based on the ABI and CPU in use. For example, `mips-linux-gnu-clang -mips64r2 -mabi=64` should produce an ELF64 as should `mips64-linux-gnu-clang -mabi=64`. Conversely, `mips64-linux-gnu-clang -mabi=n32` should produce an ELF32 as should `mips-linux-gnu-clang -mips64r2 -mabi=n32`. This patch fixes the e_flags but leaves the ELF32 vs ELF64 issue for now since there is no apparent way to base this decision on the ABI and CPU.

Move the Mips target to storing the ABI in the TargetMachine rather than on MipsSubtargetInfo. This required a bit of massaging in the MC level to handle this since MC is a) largely a collection of disparate classes with no hierarchy, and b) there's no overarching equivalent to the TargetMachine, instead only the subtarget via MCSubtargetInfo (which is the base class of TargetSubtargetInfo). We're now storing the ABI in both the TargetMachine level and in the MC level because the AsmParser and the TargetStreamer both need to know what ABI we have to parse assembly and emit objects. The target streamer has a pointer to the one in the asm parser and is updated when the asm parser is created. This is fragile as the FIXME comment notes, but shouldn't be a problem in practice since we always create an asm parser before attempting to emit object code via the assembler. The TargetMachine now contains the ABI so that the DataLayout can be constructed dependent upon ABI. All testcases have been updated to use the -target-abi command line flag so that we can set the ABI without using a subtarget feature. Should be no change visible externally here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@227102 91177308-0d34-0410-b5e6-96231b3b80d8

Move the Mips target to storing the ABI in the TargetMachine rather than on MipsSubtargetInfo. This required a bit of massaging in the MC level to handle this since MC is a) largely a collection of disparate classes with no hierarchy, and b) there's no overarching equivalent to the TargetMachine, instead only the subtarget via MCSubtargetInfo (which is the base class of TargetSubtargetInfo). We're now storing the ABI in both the TargetMachine level and in the MC level because the AsmParser and the TargetStreamer both need to know what ABI we have to parse assembly and emit objects. The target streamer has a pointer to the one in the asm parser and is updated when the asm parser is created. This is fragile as the FIXME comment notes, but shouldn't be a problem in practice since we always create an asm parser before attempting to emit object code via the assembler. The TargetMachine now contains the ABI so that the DataLayout can be constructed dependent upon ABI. All testcases have been updated to use the -target-abi command line flag so that we can set the ABI without using a subtarget feature. Should be no change visible externally here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@227102 91177308-0d34-0410-b5e6-96231b3b80d8

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] Fix ELF e_flags related to -mabicalls and -mplt. Summary: These options are not implemented yet but we act as if they are always given. The integrated assembler is driven by the clang driver so the e_flag test cases should match the e_flags emitted by GCC+GAS rather than GAS by itself.

# MIPS64EL-MIPS64-O32-NAN2008: Flags [ (0x60001504)
[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).

[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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200332 91177308-0d34-0410-b5e6-96231b3b80d8

# Default ABI for MIPS64 is N64 as opposed to GCC/GAS (N32)
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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200138 91177308-0d34-0410-b5e6-96231b3b80d8
