[MC] Target-Independent Small Data Section Handling
...roach for handling small global
variables in its TargetLoweringObjectFile subclass. Also, the clang driver
responds to the `-G <bytes>` flag so the user can define a cutoff size
other than 8 (or 0 to disable small data altogether).
It seems the Hexagon and Lanai targets duplicate much of the
IsGlobalInSmallSection handling from the MIPS target, but perform the same
basic classification tasks:
1. Pass GlobalObject to target-declared IsGlobalInSmallSection.
If it's a declaration, skip to step 4.
2. Pass GlobalObject to target-independent
TargetLoweringObjectFile::getKindForGlobal.
3. Ensure the retu...

[LLVMdev] Problem with Store of i8 in a global address
...arguments: source register and address (immediate). This
instruction is not available in Mips, but it is in Hexagon, so I copied
from Hexagon the following, adapting it to my registers:
- In ISelLowering.h: CONST32 and CONST32_GP
- In ISelLowering.cpp: LowerGlobalAddress
- In TargetObjectFile.cpp: isGlobalInSmallSection
- In InstrInfo.td:
def SDTmyCONST32 : SDTypeProfile<1, 1, [
SDTCisVT<0, i32>,
SDTCisVT<1, i32>,
SDTCisPtrTy<0>]>;
def myCONST32 : SDNode<&q...
