2010-03-24crypto: aesni-intel - Fix another CTR build failure with gas 2.16.1Huang Ying
The previous AES-NI CTR optimization compiling failure gas 2.16.1 fix introduces another compiling failure by itself. This patch fixes that.

2010-03-13crypto: aesni-intel - Fix CTR optimization build failure with gas 2.16.1Huang Ying
Andrew Morton reported that AES-NI CTR optimization failed to compile with gas 2.16.1, the error message is as follow: arch/x86/crypto/aesni-intel_asm.S: Assembler messages: arch/x86/crypto/aesni-intel_asm.S:752: Error: suffix or operands invalid for `movq' arch/x86/crypto/aesni-intel_asm.S:753: Error: suffix or operands invalid for `movq' To fix this, a gas macro is defined to assemble movq with 64bit general purpose registers and XMM registers. The macro will generate the raw .byte sequence for needed instructions.

2009-11-09x86: Generate .byte code for some new instructions via gas macroHuang Ying
It will take some time for binutils (gas) to support some newly added instructions, such as SSE4.1 instructions or the AES-NI instructions found in upcoming Intel CPU. To make the source code can be compiled by old binutils, .byte code is used instead of the assembly instruction. But the readability and flexibility of raw .byte code is not good. This patch solves the issue of raw .byte code via generating it via assembly instruction like gas macro. The syntax is as close as possible to real assembly instruction. Some helper macros such as MODRM is not a full feature implementation. It can be extended when necessary. Signed-off-by: Huang Ying <ying.huang@intel.com> Acked-by: H.
