| | | | | | | | | | | | | | | Summary: This fixes PR27682. Additionally, '.set micromips' by itself is not sufficient to raise the EF_MIPS_MICROMIPS flag. It is also necessary to emit a microMIPS instruction. This has also been fixed.

| | | | | | | | | | | | | | | | | | 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.

* [mips] Fix inconsistent .cprestore behaviour between direct object emission ↵Daniel Sanders2016-05-061-0/+5
| | | | | | | | | | | | | | | | | | | and assembling. Summary: Direct object emission has an initialization order problem where an InitMCObjectFile is called after MipsTargetELFStreamer determines whether PIC is enabled by default or not. There doesn't seem to be point that initializes all cases so split the responsibility between MipsTargetELFStreamer and MipsAsmPrinter.

Summary: The portion in MipsAsmParser is responsible for figuring out which expansion to use, while the portion in MipsTargetStreamer is responsible for emitting it. This allows us to remove the call to isIntegratedAssemblerRequired() which is currently ensuring the effect of .cprestore only occurs when writing objects.

| | | | | | | | | | | | | | | | | | | Summary: This will allows us to eliminate some magic numbers from the offset operand of branch instructions in favour of symbols and makes it possible to avoid double-filling delay slots when clang is given -save-temps. parseDirectiveCpRestore() is calling isIntegratedAssemblerRequired() for the moment since correctly pushing the generation of these instructions into the ELF target streamer is tricky enough to warrant a separate patch.

* Move the Mips target to storing the ABI in the TargetMachine ratherEric Christopher2015-01-261-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 227102

Before this patch, the assembler never disabled feature bits. For example, .set mips64 .set mips32r2 would result in the 'OR' of mips64 with mips32r2 feature bits which isn't right. Unfortunately this isn't trivial to fix because there's not an easy way to clear feature bits as the algorithm in MCSubtargetInfo (ToggleFeature) only clears the bits that imply the feature being cleared and not the implied bits by the feature (there's a better explanation to the code I added).

* [mips] Add support for -modd-spreg/-mno-odd-spregDaniel Sanders2014-07-101-8/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: When -mno-odd-spreg is in effect, 32-bit floating point values are not permitted in odd FPU registers. The option also prohibits 32-bit and 64-bit floating point comparison results from being written to odd registers. This option has three purposes: * It allows support for certain MIPS implementations such as loongson-3a that do not allow the use of odd registers for single precision arithmetic. * When using -mfpxx, -mno-odd-spreg is the default and this allows us to statically check that code is compliant with the O32 FPXX ABI since mtc1/mfc1 instructions to/from odd registers are guaranteed not to appear for any reason. Once this has been established, the user can then re-enable -modd-spreg to regain the use of all 32 single-precision registers. * When using -mfp64 and -mno-odd-spreg together, an O32 extension named O32 FP64A is used as the ABI. This is intended to provide almost all functionality of an FR=1 processor but can also be executed on a FR=0 core with the assistance of a hardware compatibility mode which emulates FR=0 behaviour on an FR=1 processor. * Added '.module oddspreg' and '.module nooddspreg' each of which update the .MIPS.abiflags section appropriately * Moved setFpABI() call inside emitDirectiveModuleFP() so that the caller doesn't have to remember to do it. * MipsABIFlags now calculates the flags1 and flags2 member on demand rather than trying to maintain them in the same format they will be emitted in. There is one portion of the -mfp64 and -mno-odd-spreg combination that is not implemented yet. Moves to/from odd-numbered double-precision registers must not use mtc1. I will fix this in a follow-up.
