From a245487fa29f7e132f6f2c42d84bdaf5fc099922 Mon Sep 17 00:00:00 2001 From: iximeow Date: Mon, 16 Dec 2019 01:02:56 -0800 Subject: support aesni this includes respecting ModRM_XXXX-style operand codes from alternate 0f opcode maps. this MAY introduce bugs where an opcode 0fXX is valid by the 0f map, invalid by the 660f map, and we see a sequence like 660fXXYY. if YY results in 0fXX being invalid by 660f, we may have to fall back to reading opcode XX as an 0f opcode, where YY needs to be re-read with the correct operand code. hopefully this doesn't actually happen... --- test/test.rs | 32 ++++++++++++++++++++++++++++++++ 1 file changed, 32 insertions(+) (limited to 'test') diff --git a/test/test.rs b/test/test.rs index e2c52fe..cd2f6c0 100644 --- a/test/test.rs +++ b/test/test.rs @@ -98,6 +98,38 @@ fn test_cvt() { } #[test] +fn test_aesni() { + fn test_instr(bytes: &[u8], text: &'static str) { + test_display_under(&InstDecoder::minimal().with_aesni(), bytes, text); + test_display_under(&InstDecoder::default(), bytes, text); + test_invalid_under(&InstDecoder::minimal(), bytes); + } + + fn test_instr_invalid(bytes: &[u8]) { + test_invalid_under(&InstDecoder::minimal().with_aesni(), bytes); + test_invalid_under(&InstDecoder::default(), bytes); + } + + test_instr(&[0x66, 0x0f, 0x38, 0xdb, 0x0f], "aesimc xmm1, [rdi]"); + test_instr(&[0x66, 0x4f, 0x0f, 0x38, 0xdb, 0xcf], "aesimc xmm9, xmm15"); + + test_instr(&[0x66, 0x0f, 0x38, 0xdc, 0x0f], "aesenc xmm1, [rdi]"); + test_instr(&[0x66, 0x4f, 0x0f, 0x38, 0xdc, 0xcf], "aesenc xmm9, xmm15"); + + test_instr(&[0x66, 0x0f, 0x38, 0xdd, 0x0f], "aesenclast xmm1, [rdi]"); + test_instr(&[0x66, 0x4f, 0x0f, 0x38, 0xdd, 0xcf], "aesenclast xmm9, xmm15"); + + test_instr(&[0x66, 0x0f, 0x38, 0xde, 0x0f], "aesdec xmm1, [rdi]"); + test_instr(&[0x66, 0x4f, 0x0f, 0x38, 0xde, 0xcf], "aesdec xmm9, xmm15"); + + test_instr(&[0x66, 0x0f, 0x38, 0xdf, 0x0f], "aesdeclast xmm1, [rdi]"); + test_instr(&[0x66, 0x4f, 0x0f, 0x38, 0xdf, 0xcf], "aesdeclast xmm9, xmm15"); + + test_instr(&[0x66, 0x0f, 0x3a, 0xdf, 0x0f, 0xaa], "aeskeygenassist xmm1, [rdi], 0xaa"); + test_instr(&[0x66, 0x4f, 0x0f, 0x3a, 0xdf, 0xcf, 0xaa], "aeskeygenassist xmm9, xmm15, 0xaa"); +} + +#[test] fn test_sse3() { fn test_instr(bytes: &[u8], text: &'static str) { test_display_under(&InstDecoder::minimal().with_sse3(), bytes, text); -- cgit v1.1
