* [mips] Remap move as or.Vasileios Kalintiris2015-08-113-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | Summary: This patch remaps the assembly idiom 'move' to 'or' instead of 'daddu' or 'addu'. The use of addu/daddu instead of or as move was highlighted as a performance issue during the analysis of a recent 64bit design. Originally move was encoded as 'or' by binutils but was changed for the r10k cpu family due to their pipeline which had 2 arithmetic units and a single logical unit, and so could issue multiple (d)addu based moves at the same time but only 1 logical move. This patch preserves the disassembly behaviour so that disassembling a old style (d)addu move still appears as move, but assembling move always gives an or Patch by Simon Dardis.

* MC: Remove MCSubtargetInfo() default constructorDuncan P. N. Exon Smith2015-07-101-3/+1
| | | | | | | | | | | | | | | | | | | | | Force all creators of `MCSubtargetInfo` to immediately initialize it, merging the default constructor and the initializer into an initializing constructor. Besides cleaning up the code a little, this makes it clear that the initializer is never called again later. Out-of-tree backends need a trivial change: instead of calling: auto *X = new MCSubtargetInfo(); InitXYZMCSubtargetInfo(X, ...); return X; they should call: return createXYZMCSubtargetInfoImpl(...); There's no real functionality change here. llvm-svn: 241957
* Change the last few internal StringRef triples into Triple objects.Daniel Sanders2015-07-061-2/+2
| | | | | | | | | | | | | | | | | | | | Summary: This concludes the patch series to eliminate StringRef forms of GNU triples from the internals of LLVM that began in r239036. At this point, the StringRef-form of GNU Triples should only be used in the public API (including IR serialization) and a couple objects that directly interact with the API (most notably the Module class). The next step is to replace these Triple objects with the TargetTuple object that will represent our authoratative/unambiguous internal equivalent to GNU Triples.

* [mips] [IAS] Refactor the emitDirectiveModuleFP() functions. NFC.Toma Tabacu2015-06-251-14/+3
| | | | | | | | | | | | | | | | | | | | Summary: Simplify emitDirectiveModuleFP() by having it just print the current information from MipsABIFlagsSection and doing an updateABIInfo() before such calls. This prevents us from forgetting to update the STI.FeatureBits, because updateABIInfo() uses those to update the MipsABIFlagsSection object, and also makes sure we use the update mechanism from MipsABIFlagsSection.

* [mips][ias] Expand on r238751 to cover as many relocs as possible.Daniel Sanders2015-06-161-22/+36
| | | | | | | | | | | | | | | | | | | | | | | Summary: Relocs that can be converted from absolute to PC-relative now do so if IsPCRel is true. Relocs that require PC-relative now call llvm_unreachable() if IsPCRel is false and similarly those that require absolute assert that IsPCRel is false. Note that while it looks like some relocs (e.g. R_MIPS_26) can be converted into the MIPS32r6/MIPS64r6 relocs (R_MIPS_PC*_S2), it isn't actually valid to do so. Placeholders have been left in the testcase for unsupported relocs and relocs that cannot be generated at the moment.

* Bring back r239006 with a fix.Rafael Espindola2015-06-043-14/+5
| | | | | | | | | | | | | | | | | | | The fix is just that getOther had not been updated for packing the st_other values in fewer bits and could return spurious values: - unsigned Other = (getFlags() & (0x3f << ELF_STO_Shift)) >> ELF_STO_Shift; + unsigned Other = (getFlags() & (0x7 << ELF_STO_Shift)) >> ELF_STO_Shift; Original message: Pack the MCSymbolELF bit fields into MCSymbol's Flags.

* [mips] Add support for dynamic stack realignment.Vasileios Kalintiris2015-06-022-0/+5
| | | | | | | | | | | | | | | | | | | | Summary: With this change we are able to realign the stack dynamically, whenever it contains objects with alignment requirements that are larger than the alignment specified from the given ABI. We have to use the $fp register as the frame pointer when we perform dynamic stack realignment. In complex stack frames, with variably-sized objects, we reserve additionally the callee-saved register $s7 as the base pointer in order to reference locals.

* Use std::bitset for SubtargetFeatures.Michael Kuperstein2015-05-262-21/+21
| | | | | | | | | | | | Previously, subtarget features were a bitfield with the underlying type being uint64_t. Since several targets (X86 and ARM, in particular) have hit or were very close to hitting this bound, switching the features to use a bitset. No functional change. The first several times this was committed (e.g. r229831, r233055), it caused several buildbot failures. Apparently the reason for most failures was both clang and gcc's inability to deal with large numbers (> 10K) of bitset constructor calls in tablegen-generated initializers of instruction info tables. This should now be fixed. llvm-svn: 238192

| | | | | | | | | | | | | | | | | | | | | | | | This starts merging MCSection and MCSectionData. There are a few issues with the current split between MCSection and MCSectionData. * It optimizes the the not as important case. We want the production of .o files to be really fast, but the split puts the information used for .o emission in a separate data structure. * The ELF/COFF/MachO hierarchy is not represented in MCSectionData, leading to some ad-hoc ways to represent the various flags. * It makes it harder to remember where each item is. The attached patch starts merging the two by moving the alignment from MCSectionData to MCSection. Most of the patch is actually just dropping 'const', since MCSectionData is mutable, but MCSection was not. llvm-svn: 237936
