Yousong Zhou 71a0a72456 MIPS: UAPI: Ignore __arch_swab{16,32,64} when using MIPS16 ... Some GCC versions (e.g. 4.8.3) can incorrectly inline a function with MIPS32 instructions into another function with MIPS16 code [1], causing the assembler to genereate incorrect binary code or fail right away complaining about unrecognized opcode. In the case of __arch_swab{16,32}, when inlined by the compiler with flags `-mips32r2 -mips16 -Os', the assembler can fail with the following error. {standard input}:79: Error: unrecognized opcode `wsbh $2,$2' For performance concerns and to workaround the issue already existing in older compilers, just ignore these 2 functions when compiling with mips16 enabled. [1] Inlining nomips16 function into mips16 function can result in undefined builtins, https://gcc.gnu.org/bugzilla/show_bug.cgi?id=55777 Signed-off-by: Yousong Zhou <yszhou4tech@gmail.com> Cc: Maciej W.
