bool GlobalValue::canBeOmittedFromSymbolTable ( ) const

True if GV can be left out of the object symbol table.

This is the case for linkonce_odr values whose address is not significant. While legal, it is not normally profitable to omit them from the .o symbol table. Using this analysis makes sense when the information can be passed down to the linker or we are in LTO.

◆ isDefinitionExact()

bool llvm::GlobalValue::isDefinitionExact ( ) const

inline

Return true if the currently visible definition of this global (if any) is exactly the definition we will see at runtime.

Non-exact linkage types inhibits most non-inlining IPO, since a differently optimized variant of the same function can have different observable or undefined behavior than in the variant currently visible. For instance, we could have started with

void foo(int *v) { int t = 5 / v[0]; (void) t; }

and "refined" it to

void foo(int *v) { }

However, we cannot infer readnone for foo, since that would justify DSE'ing a store to v[0] across a call to foo, which can cause undefined behavior if the linker replaces the actual call destination with the unoptimized foo.

Inlining is okay across non-exact linkage types as long as they're not interposable (see isInterposable), since in such cases the currently visible variant is a correct implementation of the original source function; it just isn't the only correct implementation.
