LLVM backend for 6502
dc73dc09f1
The 'common' section TLS is not implemented. Current C/C++ TLS variables are not placed in common section. DWARF debug info to get the address of TLS variables is not generated yet. clang and driver changes in http://reviews.llvm.org/D10524 Added -femulated-tls flag to select the emulated TLS model, which will be used for old targets like Android that do not support ELF TLS models. Added TargetLowering::LowerToTLSEmulatedModel as a target-independent function to convert a SDNode of TLS variable address to a function call to __emutls_get_address. Added into lib/Target/*/*ISelLowering.cpp to call LowerToTLSEmulatedModel for TLSModel::Emulated. Although all targets supporting ELF TLS models are enhanced, emulated TLS model has been tested only for Android ELF targets. Modified AsmPrinter.cpp to print the emutls_v.* and emutls_t.* variables for emulated TLS variables. Modified DwarfCompileUnit.cpp to skip some DIE for emulated TLS variabls. TODO: Add proper DIE for emulated TLS variables. Added new unit tests with emulated TLS.
