GAS treats the R5900 as MIPS III, with some modifications. The MIPS III designation means that the GNU C Library will try to assemble the LL and SC instructions, even though they are not implemented in the R5900. GAS will therefore produce the following errors: Error: opcode not supported on this processor: r5900 (mips3) `ll $2,0($4)' Error: opcode not supported on this processor: r5900 (mips3) `sc $6,0($4)' The MIPS II ISA override as used here enables the kernel to trap and emulate the LL and SC instructions, as required. This change has been tested by compiling the GNU C Library 2.27 with a GCC 8.2.0 cross-compiler for mipsr5900el-unknown-linux-gnu under Gentoo. * sysdeps/mips/sys/tas.h (_test_and_set): Handle the R5900 CPU with the ISA override. |
