MSP430: interrupt vector number out of bounds error in v6/trunk (with patch)
...ms.getLimitedValue(255);
if ((Num & 1) || Num > 30) {
S.Diag(AL.getLoc(), diag::err_attribute_argument_out_of_bounds)
<< AL.getName() << (int)NumParams.getSExtValue()
<< NumParamsExpr->getSourceRange();
return;
}
Also, the __isr_ symbol is emitted with the vector number divided by 2.
// Step 3: Emit ISR vector alias.
unsigned Num = attr->getNumber() / 2;
llvm::GlobalAlias::create(llvm::Function::ExternalLinkage,
"__isr_" + Twine(Num), F);
