Because binutils2.42 corrects the implementation of ".align [abs-expr,[abs-expr[,abs-expr]]]". The macro ASM_OUTPUT_ALIGN_WITH_NOP in GCC uses this assembler directive, and an error occurs. See link below for detailed description. https://gcc.gnu.org/pipermail/gcc-patches/2024-February/645067.htmlIn order to solve the above problems, do the following operations: 1. Delete macro definition ASM_OUTPUT_ALIGN_WITH_NOP. (cherry pick r14-4674) 2. Check whether binutils supports the relax function. (cherry pick r14-4160) 3. Disable relaxation if the assembler don't support conditional branch relaxation. (cherry pick r14-5434) PR112299 is also fixed here. Lulu Cheng (2): LoongArch: Delete macro definition ASM_OUTPUT_ALIGN_WITH_NOP. LoongArch: Check whether binutils supports the relax function. If supported, explicit relocs are turned off by default.
