This support does two main things: 1. Implement support for three new relocation items in bfd. The three new relocation items are shown below: R_LARCH_TLS_LE_ADD_R R_LARCH_TLS_LE_HI20_R R_LARCH_TLS_LE_LO12_R 2. ADD a new macro RELOCATE_TLS_TP32_HI20 Handle problems caused by symbol extensions in TLS LE, The processing is similar to the macro RELOCATE_CALC_PC32_HI20 method. 3. Implement the tls le relax function. bfd/ChangeLog: * bfd-in2.h: Add relocs related to tls le relax. * elfnn-loongarch.c: (loongarch_relax_tls_le): New function. (RELOCATE_TLS_TP32_HI20): New macro.
