◆ computeGlobalGOTEquivs()

void AsmPrinter::computeGlobalGOTEquivs ( Module & M )

Unnamed constant global variables solely contaning a pointer to another globals variable act like a global variable "proxy", or GOT equivalents, i.e., it's only used to hold the address of the latter.

Unnamed constant global variables solely contaning a pointer to another globals variable is equivalent to a GOT table entry; it contains the the address of another symbol.

One optimization is to replace accesses to these proxies by using the GOT entry for the final global instead. Hence, we select GOT equivalent candidates among all the module global variables, avoid emitting them unnecessarily and finally replace references to them by pc relative accesses to GOT entries.

Optimize it and replace accesses to these "GOT equivalents" by using the GOT entry for the final global instead. Compute GOT equivalent candidates among all global variables to avoid emitting them if possible later on, after it use is replaced by a GOT entry access.

◆ OutContext

MCContext& llvm::AsmPrinter::OutContext

This is the context for the output file that we are streaming.

This owns all of the global MC-related objects for the generated translation unit.
