Current JIT includes fall-back code for byte-swapping on older ARM archs, but fails tests from module test_bpf: test_bpf: torvalds#299 ALU_END_FROM_BE 64: 0x0123456789abcdef >> 32 -> 0x01234567 jited:1 ret 4530944 != -271733879 (0x452300 != 0xefcdab89)FAIL (1 times) test_bpf: torvalds#303 ALU_END_FROM_BE 64: 0xfedcba9876543210 >> 32 -> 0xfedcba98 jited:1 ret 12246016 != 271733878 (0xbadc00 != 0x10325476)FAIL (1 times) test_bpf: torvalds#315 BSWAP 64: 0x0123456789abcdef >> 32 -> 0xefcdab89 jited:1 ret 4530944 != -271733879 (0x452300 != 0xefcdab89)FAIL (1 times) test_bpf: torvalds#319 BSWAP 64: 0xfedcba9876543210 >> 32 -> 0x10325476 jited:1 ret 12246016 != 271733878 (0xbadc00 != 0x10325476)FAIL (1 times) These problems can be traced back to emit_rev32(). Rewrite as simpler code, going from 10 insns to 4 and dropping use of 2 temp registers, while also fixing the test failures above. Signed-off-by: Tony Ambardar <[email protected]>
