It looks like this version of patch does exactly this.
It does not open file separately and does not parse file name.
The only thing which is additionally done is for already opened file :
"well, if you didn't specify a section index, we'll use the first section that covers this address" :
uint64_t SymbolizableObjectFile::getModuleSectionIndexForAddress(
uint64_t Address) const {
for (SectionRef Sec : Module->sections()) {
if (!Sec.isText() || Sec.isVirtual())
continue;
if (Address >= Sec.getAddress() &&
Address <= Sec.getAddress() + Sec.getSize()) {
return Sec.getIndex();
}
}
return object::SectionedAddress::UndefSection;
}
I think it looks very close to above description.
