Member Typedef Documentation

AliasMapTy

using llvm::AsmPrinter::AliasMapTy = DenseMap<uint64_t, SmallVector<const GlobalAlias *, 1> >

Print a general LLVM constant to the .s file.

On AIX, when an alias refers to a sub-element of a global variable, the label of that alias needs to be emitted before the corresponding element.

GOTEquivUsePair

using llvm::AsmPrinter::GOTEquivUsePair = std::pair<const GlobalVariable *, unsigned>

Map global GOT equivalent MCSymbols to GlobalVariables and keep track of its number of uses by other globals.

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.

usesCFIWithoutEH()

bool AsmPrinter::usesCFIWithoutEH

(

)

const

Since emitting CFI unwind information is entangled with supporting the exceptions, this returns true for platforms which use CFI unwind information for other purposes (debugging, sanitizers, ...) when MCAsmInfo::ExceptionsType == ExceptionHandling::None.
