[LLVMdev] Preferred alignment of globals > 16bytes
...l globals bigger than 16 bytes are being 16
byte aligned by LLVM (assuming there isn't an explicitly requested
alignment). I'd really rather avoid this, at least for the XCore
backend. I tracked this down to the following code in TargetData.cpp:
if (GV->hasInitializer() && GVAlignment == 0) {
if (Alignment < 16) {
// If the global is not external, see if it is large. If so,
give it a
// larger alignment.
if (getTypeSizeInBits(ElemType) > 128)
Alignment = 16; // 16-byte alignment.
}
}
I was a bit surprised to see these nu...
