...er_model Suppose there are two functions in a module which have different sets of function attributes. One function has attributes for "-ffast-math" (foo1) and the other (foo0) has attributes for "-fno-fast-math". In that case, which set of eabi attributes should ARMAsmPrinter::emitAttributes emit? ARMAsmPrinter::emitAttributes is called once at the start of a file (not once per every function), so I assume it has to merge those attributes which have different values or reject the IR if it discovers incompatibilities. define double @foo0(double %a) #0 { entry: %add = fadd double %a...

...MCStreamer interface, with the caller givin the ability to give hints as to what section to place the symbol into. instead of SwitchSection, there would be BeginSymbol, and SymbolSymbol, it would be illegal to call any EmitXXX function outside of these two calls BeginSymbol(Symbol, SectionHint) EmitAttribute(...) EmitAttribute(...) ... StartFragmentEmission() EmitFragment(...) EmitFragment(...) ... EndSymbol() Object file writers would typically start recording fragments and attributes for a symbol on the BeginSymbol, then at EndSymbol they would evaluate what was streamed, and decide what...

...e::getSubtargetImpl(const Function &) to initialize STI (pointer to the per-function subtarget object). Currently, the version of TargetMachine::getSubtargetImpl that doesn’t take a const Function& parameter is called, which returns the module-level subtarget object. 5. Fix ARMAsmPrinter::emitAttributes to compute the value of TargetOptions::UnsafeFPMath based on the function attributes of all the functions in the module being compiled (see the link below). http://lists.cs.uiuc.edu/pipermail/llvmdev/2014-December/079904.html 6.
