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

This question is about the assembler, and would be better directed to
binutils@sourceware.org. See http://sourceware.org/binutils/.
I believe the answer is to use 'dli' if you want to load a 64-bit
constant. Note that your 2.9-gnupro-99r1 toolchain is six years old.
