Hello, Latest version of mips64-elf-as produces an error message when assembling li $1, 0xc000000000000000 start.S:154: Error: Number (0xc000000000000000) larger than 32 bits Previously (in mips64vr5xxx-elf-as version 2.9-gnupro-99r1) this macro was expanded as lui $1, 0xc000 dsll32 $1, $1, 0x10 Does any particular mips64 architecture support this macro extension or 64-bit immediates are not allowed at all? TIA, Vladimir
